How to Dispose Your Air Conditioner

Ever wondered how much air-conditioning Singaporeans actually use? We have more installed air-conditioning units per person than other parts of Southeast Asia, which shows that we’re truly air-conditioning addicted. Apart from the amount of energy we guzzle, we should also think about how many air conditioners we’re going to dispose of. Air conditioners have a typical lifespan of between 10 and 15 years, and trying to extend it beyond that would prove to be damaging and inefficient. This is especially so for older models that are not as efficient as modern ones. Getting rid of your air conditioner is not as simple as throwing it down the refuse chute. There are certain things you need to do to ensure that it’s safely disposed of. Why We Need to Dispose Our Air Conditioners Carefully Air conditioners use refrigerants to complete the entire cooling process. Even if you use an air conditioner that uses more environmentally friendly refrigerants, like a LG R32 aircon that uses an LG R32 refrigerant gas, it will still be harmful when incorrectly disposed of. Refrigerants contain greenhouse gases like hydrochlorofluorocarbon (HCFC), hydrofluorocarbon (HFC) and chlorofluorocarbon (CFC). Apart from HFC, the other gases play a part in depleting the ozone layer and therefore harm the environment. If you throw your air conditioner away in a typical landfill, the refrigerant may leak and affect the environment, increasing global warming as a result. How to Dispose Your Air Conditioner Send It to a Professional Recycling Centre Air conditioners fall under the e-waste category. The NEA has implemented e-waste recycling programmes for individuals and households. You can drop off your air conditioner at the listed recycling points to recycle your e-waste properly. As of July 2021, a regulated e-waste management system based on the Extended Producer Responsibility (EPR) approach has been in place. This system ensures that producers will undertake the responsibility of collecting and treating their products at their end-of-life. Other businesses also offer recycling programmes, like Gain City. You can take your air conditioner there for their professionals to properly dismantle and dispose of without harming the environment. Trade or Donate It Apart from sending your air conditioner to a recycling centre, you can also trade or donate it at the respective collection centres. Sometimes, you may get an incentive in return as well, depending on what the terms are. Call a Professional Air Conditioner Removal Service Provider Some companies offer an air conditioner removal service to help you dispose of your air conditioner. This method is considerably hassle-free since all you need to do is call the business and wait for them to send someone to your doorstep with a fee. Refurbish Your Air Conditioner If your air conditioner has some sentimental value, or for whatever reason that you wish not to dispose of it completely, you can choose to refurbish it instead. Since replacement can be expensive, you can opt for a cheaper method and refurbish it. Refurbishment typically involves topping up the refrigerant gas, fixing leakages in the piping, deep cleaning the inner systems, and repairing the condenser fins and fans. However, you should note that air conditioners made before 2010 cannot be refurbished since they use the old R-22 refrigerant. If you want to check whether an older model can be converted to be compatible with newer refrigerants, you can see whether there are brands that allow this.

The Ideal Air-Conditioning Temperature to Make Your WFH Productive

A work-from-home approach has become a reality over the course of the COVID-19 pandemic, which means that many of us stay home most of the day. No one knows for sure when this trend will last, but it’s definitely staying around for some time. Regardless of whether you’re working in the office or at home, an important factor is to make sure that the environment you’re working in is conducive. This can make or break your productivity and influence your work. It’s not just buying that ergonomic office chair and table or setting up multiple large computer screens - the humidity level, temperature and indoor air quality should play a part as well. In this article, we’ll talk about the best air conditioner temperature to help boost your productivity as you work from home! How Temperature Affects Productivity There’s no denying that Singapore is hot all-year-round and that being out in the sun under the mercy of the heat is torturous for many. All of us have the preferred temperature that we like to operate in, though most of us would choose a cool temperature over its warm counterpart. The right temperature goes beyond just comfort, affecting your health, mood and performance as well. It can either make you feel tired and sluggish or bright and raring to go. Certain temperatures are also not recommended for performing certain activities, while some suit others better. For example, a slightly warmer temperature may improve productivity, while a hot temperature may reduce it. Temperatures that are too cold will also reduce productivity. Complicated decisions and solving mathematical-related problems are typically difficult to do when it’s too warm as well. Maintaining an Ideal Temperature for WFH It’s impossible to find an ideal temperature for all the employees at the workplace, but when you’re working from home and you’re the only one in the room, it means that you now have complete access to the temperature you want. As a rule of thumb, productivity is best between 21 to 22 degrees celsius. Research also shows that a temperature of 25 degrees reduces error rates while boosting productivity. Below that, the mistakes increased and productivity dropped by half. Knowing it is insufficient - you need to understand how to reach and maintain this ideal temperature. This is where a smart aircon and smart aircon system come in. They can help to maintain your desired temperature using smart temperature triggers, modes and settings. Humidity and Indoor Air Quality A smart air conditioner offers many amazing benefits, and it’s up to you to make full use of them! For example, you can use the dry mode to maintain the humidity level in the room. Some smart air conditioners can measure the level of humidity as well. We tend to have high humidity levels because of our climate, so these tools can be very helpful. You can also use your air conditioner’s powerful filters to improve the indoor air quality of the room. After all, who enjoys sneezing and feeling terrible because of bad air quality, especially when you’re going to be cooped up indoors for most of the day?

How to Prevent Your Compressor From Breaking Down

Occasionally, your trusty air conditioner may run into problems. Some of these issues will be easier and less costly to fix, like dirty air filters and a blocked duct. Others will be more expensive, like a compressor failure. When the worst happens, you need to contact your aircon contractor Singapore. Thankfully, most of these issues, whether big or small, can be prevented before they occur or worsen to the point of no return. Here, we’ll discuss the different ways you can prevent your compressor from breaking down, saving yourself a hefty sum of replacement fees. The Role of an Air Conditioner’s Compressor Considered the core or heart of an air conditioner, a compressor is in charge of compressing the cooling substance, the refrigerant, so that it can travel inside the air conditioner and get rid of heat. A compressor has about the same lifespan as an air conditioner of 10 to 15 years. However, this is only so if you maintain it carefully, because failure to do so can cause increased wear and tear. Issues like dirt, dust, debris and even refrigerant leaks can affect the compressor in a detrimental way. When the compressor breaks down, you’ll most likely need to replace the entire component. Common Causes of Compressor Failure Displacement of the Evaporator Motor A displaced evaporator motor forces the refrigerant to return to the compressor. This means that it’ll drive the compressor oil out of its position and lead to lubrication problems. This may result in the compressor losing its efficiency and eventually stopping its operations. Stuck Dirt and Debris When it’s placed outdoors weathering the outside and elements, it means that outdoor pollutants and moisture can easily go into the unit and result in issues. Air can also enter, dispelling the refrigerant located in the condenser. This can cause the temperature inside the compressor to increase and lead to oil carbonisation where the discharge valve is. As a result, residue buildup occurs and causes the valves to leak. Leaking valves further contribute to a temperature increase and more damage to the compressor. How to Prevent Your Compressor From Breaking Down Get Rid of Litter Surrounding Your Outdoor Unit Just because we don’t see it like the indoor unit, it doesn’t mean that you shouldn’t maintain and take care of your outdoor unit. From time to time, pollutants and clutter can accumulate around the outdoor unit. This includes dirt, dust and grime. If it’s located close to trees, leaves may occasionally land nearby as well. You need to clean the outdoor unit on a regular basis to ensure that these substances don’t build up and interfere with its functioning. Lubricate Your Air Conditioner A compressor is a key component that also requires constant lubrication. Lubricating it lowers frictional wear on the bearings and other moving parts, cools the refrigerant gas when it’s being compressed, and seals against potential refrigerant gas leakage. Keeping your air conditioner lubricated is essential in maintaining your compressor’s functioning. Clean Your Coils Regularly At this point, you should realise that cleaning plays a big role in the maintenance of your air conditioner. Air conditioner coils are susceptible to accumulating plenty of dirt and debris, therefore requiring constant cleaning. If you skip on this step, you risk it interfering with the heat exchange process. In this scenario, you force the compressor to work extra hard to remove heat.

How to Fix Refrigerant Issues

Air conditioners depend on the refrigerants they use to cool down their surroundings. A refrigerant takes in outside heat and releases cool air after it travels through the compressor and evaporator. Refrigerant issues are also a type of problem that air conditioners can run into. In this article, we’ll take you through the common refrigerant issues and how to fix them. How Refrigerant Works Let’s recap. An air conditioner’s refrigerant helps to cool plenty of appliances, including your air conditioner, refrigerator and freezer. The refrigerant travels through the inner copper coils in the evaporator and condenser to take in heat and release it into the outside environment. It shifts from a low-pressure gas to a high-pressure liquid that then moves along with a fan’s help. This liquid continues to compress before it’s quickly removed using a special nozzle and converted into a gaseous state again. How to Determine the Refrigerant Your Air Conditioner Uses Newer air conditioners typically use either the R-410A or R-32 refrigerants that are considered more environmentally friendly. If your air conditioner was manufactured before the year 2010, it probably uses the R-22 refrigerant. For example, modern air conditioners like the Mitsubishi R32 aircon uses the R-32 refrigerant. It’s easy to find a Mitsubishi R32 refrigerant using air conditioner model in today’s market. You can also take a look at the label pasted on the side of your air conditioner’s outdoor unit. It’s usually written there, or in the user manual. If all else fails, you can simply contact the supplier you got it from and ask. Common Refrigerant Problems Frozen Coils Inside your ductless indoor unit is a network of copper coils. These coils are cooled by the refrigerant as it flows through. Although they are icy to the touch, it should not reach the point where they freeze over. If you notice frosty coils, it’s likely that the refrigerant is leaking. Warm Air Released When your air conditioner fails to fulfil its main purpose of releasing cool air, it means that you need to take a look at your refrigerant. When it lacks refrigerant, it cannot provide cooling. Although it may be due to other issues, the most probable one is because of insufficient refrigerant. How to Fix Refrigerant Issues Top Up Gas If your refrigerant levels are low, simply recharge your refrigerant. Remember to only engage a professional air conditioner contractor to do this because of the high levels of pressure and because refrigerants can be toxic. Your air conditioner contractor will top up the gas swiftly and safely without doing any damage to the system. Check for Leaks Sometimes, the problem doesn’t lie with insufficient gas. It can be because of a leak that’s allowing the refrigerant to escape. Enlist the help of an air conditioner expert to help you conduct a thorough check and seal up the leaks that they find. If the refrigerant level is too low, proceed to top it up as well.

How We Can Make Air-Conditioning Better for the Environment (Part 1)

We’re not going to sugarcoat this: as wonderful as air conditioners are to people, they’re bad news for the environment. As an increasing number of people are becoming aware of the harsh effects everyday products leave on our planet, air conditioners have been relooked at over and over again in a bid to seek out a more environmentally friendly and sustainable solution. We’ll take you through how you can make a better choice when you look out for air conditioners with certain characteristics and features! Yes, Air Conditioners Are Bad News, But… Your cooling comfort comes at a cost to the world around us, but that doesn’t mean that you can’t make informed and better choices to mitigate that cost. Here are some ways you can do that: Look for More Ticks NEA’s energy label comes with a tick rating to help consumers make more transparent decisions. This label is found in many different appliances, whether that’s your refrigerator, television or air conditioner. This tick rating denotes the energy efficiency of the different air-conditioning models. The more ticks there are, the more energy-efficient the unit is. A quick look at this label helps consumers discern more efficient models quickly. It tells consumers that the air conditioner uses less electricity to produce the same output. In turn, this helps to reduce the harmful effects of air conditioners by lowering the demand for power generation, which can be a leading source of carbon emissions. The Right Size Even if you find an air conditioner that has 5 ticks, it’s not going to help if you buy the wrong size for the place you’re cooling. Big is not always better, and small doesn’t mean you’re saving more money. It’s imperative to determine the right size for cooling so that the energy usage is efficient. You don’t spend hours cooling a small room when it could have been accomplished in 20 minutes, and you don’t buy a huge air conditioner meant for a landed property when a simple split-system only takes half the amount of energy needed to cool your HDB flat. Refrigerant The refrigerant is an important part in the way your air conditioner functions. Refrigerants are known to have detrimental effects on the ozone layer and also act as potent greenhouse gases. They’re also harmful to humans, causing potential poisoning. Choose an air conditioner that uses the R32 gas or R32 refrigerant. One such air conditioner model that uses this is the Daikin iSmile Eco. The R32 refrigerant is the newest refrigerant developed by Daikin. Smart Air Conditioners Smart air conditioners are made for the future. They’re clever in many ways to help us achieve the optimal cooling we want with ease, and also have eco-friendly features like energy usage tracking, as well as smart automated climate control. You can set your desired temperatures and even make your air conditioner turn itself off when nobody is using it. Managing it with complete control makes it easier for you to boost its energy efficiency and savings as well

The Detailed Differences Between Aircon Dry Mode and Cool Mode

As important as an air conditioner is, many people only use the on/off function and temperature settings. However, being able to fully control all other functions of your air conditioner makes it highly advantageous for you. If you haven’t already been doing so, there’s no time like the present to start delving in to the different modes of your unit. It might take a bit of time and effort, but the benefits will make all that effort worth it. Don’t wait for your aircon installer to explain the different functions one by one when you engage an aircon service Singapore for your new air conditioner. Now that we’ve explained both the air conditioner dry mode and cool mode in our earlier articles, what differences can you spot between them? Most people tend to use only the cool mode without knowing how it differs from the dry mode, and not many even know that the dry mode exists. However, the dry mode is especially useful in hot and humid countries like our own! Basic Function The basic functions are different for the two modes - the dry mode manages the humidity levels in a room, cooling it by removing moisture in the room. On the other hand, the cool mode cools the room by getting rid of existing heat. Unlike the cool mode, the dry mode does not release cold air, nor is it actively cooling the room. All that you’re experiencing is dehumidified air, the effects of which will be largely felt in a room with high humidity levels of 90% or more. Default Mode Unlike the dry mode, the cool mode is the customary setting that your air conditioner is on. It depends largely on the unit’s compressor to function smoothly. You only need to set the temperature you desire as well as the fan speed. This mode has the ability to cool your room quickly and lower the humidity levels. Icon The dry mode is usually identified on the remote control with an icon of a water drop, and the cool mode is recognised with an icon of a snowflake. Internal Function When the dry mode is turned on, the internal components of the air conditioner are functioning but they are not circulating coolant to cool the air. What happens is that the air from the room passes through the air conditioner to get rid of heat and moisture present. Maintaining Humidity Unlike the dry mode, the cool mode cannot maintain the humidity level in the room. The dry mode maintains the humidity level that is best suited for your comfort, and is recommended for use for about one to two hours. Consumes the Most Energy One difference that sets the cool mode apart from the other modes is that it takes up a lot of power. It’s never wise to leave it running for a long period of time because you can easily rack up substantial bills. Instead of doing so, you can choose to turn it on until you reach the temperature you want before turning it off, or simply keep it at a regular temperature no lower than 25 degrees celsius. Unlike the cool mode, the dry mode is energy-saving and therefore a cost-effective method to keep yourself cool and comfortable.

The Benefits of An Aircon Chemical Wash

Haven’t decided on a chemical wash for your air conditioner yet? Are you ready to continue learning about the wonders an aircon chemical wash will do for your air conditioner, whether it’s an old model or new ones like a Mitsubishi 5 ticks or Mitsubishi Heavy aircon? In this second part of our series, we’ll be introducing more reasons to get your air conditioner that long overdue chemical wash it needs to get it back running perfectly again. Let’s go! Improves the Energy Efficiency of Your Aircon When your air conditioner is filled with gunk, you’re putting unnecessary strain on your unit. This makes it hard for your air conditioner to function properly as it works harder to pass air through its different components. A chemical wash helps to eliminate this problem by getting rid of the particles stuck inside. With nothing obstructing the flow of operations, your air conditioner will be able to work optimally and boost its energy efficiency. Reduces Utility Costs A clogged air conditioner not only has lowered energy efficiency, it also contributes to a sharp increase in your electricity bill. Why pay more for less output when you can solve the problem with a chemical wash that will unblock your unit and improve its energy efficiency? By doing so, you can expect reduced electricity costs since your unit is functioning optimally. Prevents Components From Freezing There are certain components in your air conditioner that are especially prone to freezing, like the condenser, pipes and coils. A frozen condenser results in serious damage to your entire cooling system, and prevents your unit from operating. It is also expensive to replace the entire condenser unit. Using effective ways to clean the system, like a chemical wash, helps prevent freezing from happening by making sure that the fans and air ducts are clean. Prevents Leaks Refrigerant leaks are particularly dangerous and harmful not just to the air conditioner, but to the people using the appliance as well. This is because refrigerants are usually toxic substances that can be dangerous to your health when breathed in. Leakages can happen because of corrosive materials that collect near the refrigeration tubes, damaging them in the process. A chemical wash helps to prevent this, and the technician can also check the tubes and rectify any problem that is found. Cleans the Evaporator It is vital to clean your air conditioner’s evaporator properly so that the system will run properly. Dirt and debris will be detrimental to its key function of turning hot air into cool air to be released. This prevents cool air from being discharged into the environment. A chemical wash is necessary to make sure that it functions as it should.

How to Reduce Indoor Air Pollutants at Home (Part 1)

Given that outdoor air is full of exhaust fumes, cigarette smoke, and plenty of other pollutants, it’s no surprise if you think that outdoor air is more polluted. However, the levels of indoor air pollution is actually 2 to 5 times more than that of outdoor air. Let’s not forget how outdoor pollution can actually seep into indoor spaces as well, like your neighbour taking a smoke below your HDB, of which the noxious fumes will waft up to your unit if you live close enough to the ground. And yes, mortality does take place because of diseases linked to indoor air pollution. Therefore, it’s essential to make sure that you actively try to reduce indoor air pollutants to boost air quality. What Is Indoor Air Pollution? You may not smell or see it most of the time, but indoor air pollution is very real, and if you’re indoors right now, you’re probably inhaling it. Indoor air pollution is a result of different activities, from cooking to cleaning. People who use open-air fires or simple stoves are exposed to significant amounts of indoor air pollution. Cooking produces a substantial amount of tiny particles that are harmful to human health when inhaled, far more than if you were to stand by the roadside of a busy street. Many airborne chemicals are also present in homes, whether that’s the glue, sealants, paints, or materials used in your furniture, personal care products, household cleaning products and more. How to Lower Indoor Air Pollutants Air Conditioners Modern air conditioners have powerful air filters with a variety of capabilities. These filters can effectively trap pollutants like dander, dustmites, PM2.5 particles, dust mites and more, which offers you protection against their harmful effects. The efficiency of the air filter depends on the quality. You can measure this quality using the Minimum Efficiency Reporting Values (MERV), where the higher the number, the more efficiently it can trap pollutants. For example, a Daikin single-split system, as well as multi-split systems like the Daikin System 2 aircon, Daikin System 3 aircon, Daikin System 4 aircon, and Daikin System 5 aircon, have this ability. Air Purifiers Air purifiers primarily get rid of pollutants that exist in indoor air, boosting the air quality as it purifies it. An air purifier operates by filtering the air using various types of filters that target each type of indoor air pollutant. One popular term you’ll find is the High-efficiency Particulate Air (HEPA) air purifier that can get rid of over 99% of airborne particles that measure 0.3 microns in size. Crafted from fragile layers of glass fibres, this air purifier type can remove nearly all kinds of pollutants. There are also ionisers that release negatively charged anions or particles in substantial amounts into the air. They become attached to the pollutants and boost their density. This is how they get rid of pollutants in the air and land on the surface. Ventilate Often Ventilation is extremely important in maintaining a healthy and balanced indoor air quality. You need to open the windows in your home every day for a period of time to allow fresh air to enter. Doing so will force a large number of pollutants outside. You can also install exhaust fans to deliver adequate ventilation, particularly where they’ll be extra useful in the bathroom and kitchen.

How Air Conditioner Sensor Problems Can Affect Your Appliance

Air conditioners are fitted with thermostat sensors that measure the temperature of the air entering the evaporator coil. These sensors are located behind the unit’s control panel and are essential in reading and starting a room’s ideal temperature. If this sensor turns faulty, it may be due to a variety of reasons. Often, it’s because the sensor was shifted out of its original position or is being plagued by an internal issue that needs a detailed look. We’ll run you through the different problems that are associated with a faulty air conditioner sensor in this article. Signs of a Faulty Sensor Basically, a faulty sensor can be identified by the air conditioner cycling on and off between regular activation periods, or erratic cycles. It may not turn off even when your room achieves the desired temperature, and will simply continue to blow cold air. The temperature may also be cold to the point of uncomfortable. If you ignore a faulty sensor, you can expect a hike in your monthly utility bill. Dislocated Sensor Notice that the sensor was moved out of place? This can lead to things going wrong. As the sensor operates by measuring the air temperature that enters the coil, a dislocated sensor will have a difficult time performing this responsibility, hence making the unit work irregularly. If this takes place, the unit will run into difficulty in delivering reliable cooling for you. You can ascertain whether there is a dislocated sensor by checking it carefully to see if it’s out of position. However, the best thing to do is to ask a professional air conditioner technician from an aircon service company for help. Damaged Thermostat If you find that the air conditioner thermostat is still working incorrectly, it may be because of a malfunctioning thermostat. When this happens, the sensor may run erratically on and off during proper starting. In a home that is too warm or cool, the thermostat may begin to act up by switching itself on and off before it meets the desired temperature you set. This makes the air conditioner’s thermostat function sporadically in cycles, and cause the actual unit to fall short in providing the right amount of cooling to a room. Fixing a Faulty Sensor If the cause of the issue comes from the sensor itself, it’ll not cost you an arm and a leg to fix it. Instead, you can get an aircon service Singapore or aircon company Singapore to send a reliable technician to assess the connection and fix it.

How to Choose the Best Split-system Air Conditioners

Get confused easily when it comes to choosing the air conditioner that’s best suited for your home, particularly split-system air conditioners? You’re not alone, and you shouldn’t worry. In this article, we’ll walk you through the different split-system air conditioners, and how you can make a wise decision to choose the best one for yourself. What’s a Split-system Air Conditioner? Remember early on when we explained all about this common type of air conditioner? A split-system air conditioner is unlike the single-split system in the sense that it’s separated into two parts, one that’s called the evaporator, or indoor unit, that’s in charge of cooling your room, and the other which is the condenser or outdoor unit that’s responsible for getting rid of the heat outside. The indoor unit is installed inside your house to bring in cool air. Since evaporator coils are located within the indoor unit, it’s called an evaporator as well. On the other hand, the compressor, compressor coils, electrical components and condenser fan are located in the outdoor unit. The indoor unit collects the warm air from your room before cooling it down and sending it back to your room. By doing so, it heats up the refrigerant, which is in turn sent to the outdoor unit to be cooled down. The excess heat is released into the air outside. 3 Main Types of Split-system Air Conditioners Mini-split Air Conditioner System The mini-split air conditioner system is possibly the most common type of multi-split air conditioner you’ll find. Let’s talk about Daikin’s, for example - they’re the Daikin System 2 aircon, Daikin System 3 aircon, Daikin System 4 aircon and Daikin System 5 aircon that are common and popular. The indoor unit is typically installed high on the wall using brackets which is particularly beneficial for our space-constrained HDB and BTO flats. Designed to be contemporary and sleek, the pipes are connected between the indoor and outdoor unit through a concealed hole in the wall. Central Split-system Air Conditioner A central split-system unit is a complicated type of air-conditioning system. This system involves placing the main cooling unit in one location. This unit usually consists of the evaporator and air handler. From that location, the air handler unit supplies air through a series of pipes and ducts into other parts of the house. You can use thermostats to control the amount of air that enters each area. It is also considered a ducted air conditioner, and is ideal for large rooms that need powerful cooling. It requires plenty of structural considerations for its placement so it’s best to consult your designer and technician. Floor-standing Split Unit This kind of air conditioner includes tall standing units that are bigger than mini-split systems. Imagine how a refrigerator looks - that’s how they look. You can place them anywhere you wish, and there’s no need to mount brackets. Simply link up the indoor and outdoor units, plug in the power cord and switch it on. It’s suitable for use in corridors, conference rooms, lobbies and other areas with high footfall because of its amazing cooling capacity. How to Choose Your Ideal Split System Unit Budget A central air-conditioning system is relatively pricier because of the ductwork involved and added contractor costs. Servicing is also more affordable. Therefore, if you’re on a tight budget, it’s advisable to opt for a mini-split air-conditioning system instead. Efficiency Generally speaking, mini-split air conditioners, or ductless air conditioners, are more efficient than ducted air conditioners. Plus, if you’re looking to ramp up the efficiency level, you should focus on 5 ticks models. Type of Home What type of home do you plan to install your multi-split system in? If it’s a landed property and you’re building it from scratch, it may be a great choice to choose a central air-conditioning system. This gives you a centrally conditioned home that is suitable for the large size. If you’re doing up a resale HDB flat, or a BTO flat, then a mini-split air-conditioning system will suffice. Not only does it save space, it also looks modern and streamlined.

5 Ways to Troubleshoot Your Faulty Air Conditioner Fan, Part 2

Did the methods we introduced to you in our earlier article help you diagnose the problem with your faulty air conditioner fan? If you’re still confused and trying to find out the reason for this issue, fret not. We’ll take you through the remaining few causes of this phenomenon in this next article before you call your aircon repair Singapore service. Defective Dual Shaft Fan Motor The dual shaft fan motor or the circulation fan motor may occasionally run into issues. It consists of two blades, one on either side of the motor. On one side, the blade operates by taking in the external air over the condensing coil. This allows the unit to successfully dissipate the heat. On the other hand, the other blade functions by channelling the air over the evaporator coil. The dual shaft or circulation fan motor comprises bearings that can bind or loosen from regular usage. It’s simple to check whether the bearings are defective: you only need to shake the motor shaft. If this shaft is loose or refuses to turn, it means that you should replace it. Problematic Main Control and Relay Boards These boards are in charge of supplying power and voltage to various components of the air conditioner unit. One of the parts includes the fan motor. If the boards run into issues, they will not function. Before you consider changing out these boards, ensure that you’ve completely run through other potential problems first, like broken fan motor capacitors or even the fan motor itself. If you’ve checked through and they are not the source of the problem, you can go ahead to engage an aircon repair service to replace the boards. Broken Blower Motor You can determine if the blower motor is broken by checking for any odd activity inside the fan blades. If they don’t spin freely, it’s a sign that you should replace them. You should also check that the power is being supplied to the blower motor. If the motor receives power but is still insufficient for it to run, it means that it has to be replaced. A broken or defective blower motor is impossible to repair. This means that you need to replace it with a new unit completely. Faulty Rotary Switch The air conditioner’s rotary switch is responsible for triggering the fan motor. As time passes, the electrical contacts inside can gradually become closer to each other and compressed. This may lead to a failure to conduct electricity. You can use a multimeter to check whether the rotary switch needs to be changed. Burnt-out Temperature Control Thermostat Your air conditioner’s temperature control thermostat usually has various electrical contacts that can burn or fizzle out over time. If this happens, the thermostat will stop operating. If the compressor is turned on, the fan motor needs to be constantly running. If the compressor is functioning but the fan motor isn’t, it signals that the capacitor may require repairs. If both components don’t run at all, you can use a multimeter to check whether the temperature control thermostat is running.

Benefits and Disadvantages of VRF/VRV Systems

Already understood what Variable Refrigerant Volume (VRV) and Variable Refrigerant Flow (VRF) means? Remember that both terms point to the same meaning! In an earlier article, we talked about the pros and cons of choosing this type of air-conditioning system. We didn’t just stop there - there’s more to find out in this next article! What VRF/VRV Systems Are First, let’s recap what these systems are to jog your memory a bit. The VRV term was copyrighted by leading air conditioner manufacturer Daikin, so the other companies had no choice but to adopt VRF to represent the same meaning. As a majority of houses are not one big open space, especially in Singapore, it leads to the problem of uneven temperatures. Although conventional ductless air-conditioning units are effective to assist in this, VRV/VRF systems take it up a notch. Apart from using a few indoor units around the house, it also regulates refrigerant flow so that it can meet the different needs of each area. Advantages of VRF/VRV Systems Better Energy Efficiency Considered a groundbreaking technology, this innovative development that’s taken the air-conditioning industry by storm boasts leading features and components. In addition, it also possesses a high energy efficiency level that’s better than most other options. Additional Features For certain brands and models, this type of system comes with added features as well. For example, you may find air purification functions that will deliver better air quality and cleanse the surrounding air effectively. This is particularly useful if you’re installing it in a dirtier and messier environment, or if you have allergies. Quiet Relative to other types of air-conditioning systems, the VRF/VRV system is much quieter. Plus, since they require longer pipes because of the area and location needed, they’re usually placed a distance from your air-conditioning units or room. This means that the noise of the units would be significantly lowered because of the distance. The noise that is heard may even be lower than that of split-system air conditioners. Facilitates Designs Most air conditioners are mounted atop walls, but this type of system doesn’t require that. This means that you can let loose your interior design ideas and style your house with a unique positioning for your air conditioner. Environmentally Friendly Thanks to modern innovation, these VRF/VRV systems use more environmentally friendly refrigerants. For example, they may use R32 or R410-A refrigerants that are better for the environment. Disadvantages of VRF/VRV Systems Unsuitable for Certain Settings As amazing as this system is, it’s not a one-size-fits-all solution. For example, it may not be ideal to be installed in places like a laboratory or medical buildings. Unsuitable for High Surrounding Temperatures We’ve mentioned that this system tends to adjust its operations depending on the temperature that is surrounding it. For units that need high temperatures, this may not be a good choice to choose, since it may affect the unit’s operations. You may encounter problems like the aircon not cold, or other functional issues.

Choosing Between Professional and DIY Aircon Installation

Have you ever been tempted to skip calling up your trusted air conditioner expert in exchange for installing your air conditioner yourself? Perhaps it’s always looked simple to fix - just haul it up where you want it installed, put in the pipes, plug in the wires, add the trunking, turn it on and voila! If that’s what you think, it’s time to relook your perspective. When you’re dealing with something lifesaving against the heat like your air conditioner, it’s important to make sure everything is done right from the get-go. Let’s have a look at why you should always go for the professionals. Affordable Now, Not Long Term Maybe you’re feeling a little tight on your budget this month, and you don’t feel like adding to your expenses by getting a professional to install your new air conditioner for you. Sure, you can save money by avoiding that, but what happens when you’re trying to do it yourself, and halfway through you realise that you’re plugged in a wire wrongly, or your unit sounds funky when you turn it on? Despite its intimidating size and appearance, air conditioners are very delicate appliances. If something goes wrong, you can expect the entire unit to stop functioning. Would you rather spend money on a professional’s help now or risk calling the technician again and again when problems come up in the future? Mistakes can be costly, and you don’t need an expert to tell you that. Wrong Location When you’ve had plenty of experience dealing with air conditioner installations, it shows, and nothing can hide that. Compared to someone who is unfamiliar and unsure of what to do, a skilled aircon has both firsthand experience and knowledge. Whether you want to install your Panasonic 5 ticks aircon or buy Mitsubishi Starmex 5 ticks aircon, a professional can deduce certain things immediately, like the optimal location to place your indoor units for the best efficiency. Finding the right location can be a tricky part of installing your air conditioner, and you need to get it right to save on utility bills and a whole lot of hassle. Safety Remember that you’re dealing with an electrical appliance that has the potential to be extremely hazardous and dangerous. A qualified expert knows the safety regulations and understands how to avoid dangerous situations. You don’t want to risk your safety, nor that of your loved ones living together with you. Air conditioners are also mechanical appliances which calls for the need to know how complicated mechanical systems work. Lastly, air conditioners use refrigerants that can be toxic because of their chemical properties. Don’t put yourself in situations that you will regret later on! Speed When the day can be spent doing other important things, you don’t want to burn it all trying to figure out how you can install the air conditioner. Professionals who are used to this can complete the job much faster than you doing it yourself. Get an expert to do it while you sit back and relax.
