11 Reasons Why Your Air Conditioner Is Not Cold


When the weather is hot, we rely on our air conditioners to keep us cold and comfortable. Unfortunately, AC units don’t always work like they’re supposed to. If your AirCon is not cold, you’ll want to get to the bottom of the problem. These are a few potential problems you might be dealing with.

1. You May Need To Change Your Air Filter

In many cases, air conditioner problems are caused by dirty filters. Filters are supposed to be changed every few months, but a lot of people wind up forgetting about them entirely.

If you haven’t replaced your air filter in a while, now is the prime time for a replacement. Find out what kinds of filters your AC unit uses. Put in a new filter and see if your air conditioner starts blowing cold air again.

2. You Could Be Dealing With A Frozen Or Blocked Condenser

A faulty condenser can cause a number of problems. Your condenser could be blocked. Give your unit a good cleaning and get rid of dust and debris. When debris builds up inside of an AirCon, it’s difficult for the unit to function.

A condenser can also freeze if your unit hits a certain temperature. In most cases, regular maintenance is enough to prevent this from happening. If your condenser is already frozen, you may want to have a professional look at your air conditioner.

3. Your Thermostat Might Be Broken

Some AC units are connected to thermostats. While this sort of functionality can make it easier to control the temperature in your home, it can also cause some issues. If your thermostat is malfunctioning, your AirCon will also experience problems.

Check your thermostat and see if the temperature there is correct. If the thermostat is displaying the wrong temperature, it’s safe to assume that this is the cause of your AirCon problems.

4. You Could Have A Dirty Evaporator

Air conditioners have a number of parts. If one part isn’t functioning, it can influence the performance of the entire system. An evaporator is one of the parts that could cause problems. A dirty evaporator can make it difficult for an AC unit to blow cold air.

If you haven’t cleaned your air conditioner in a long time, you should open it up and try cleaning some of the parts. If you notice a dirt build-up around one of the parts, you’ll want to address that. If you’re not comfortable cleaning your unit yourself, have a professional give it a good cleaning.

5. You Might Have A Low Refrigerant Charge Or A Refrigerant Leak

As AC units age, they become more to problems like refrigerant leaks. If your unit leaks a large amount of refrigerant, it will no longer be able to produce cool air. A low refrigerant charge can also keep your unit from properly cooling your home.

Regular servicing can resolve refrigerant issues. If you want to keep an eye on your unit, you can test for leaks with a leak detector.

6. You Could Be Dealing With A Bad Compressor

The failure of a single part can cause an entire AC unit to stop functioning. Faulty compressors are very common; it’s not unusual to find a bad compressor in an AC unit. Thankfully, this is a part that can easily be replaced.

7. You Might Need To Look At Your Ductwork

If your home is cooled by an HVAC system, you should look at the ductwork around that system. Your ductwork is what sends cold air into your home. If you have a clog or cracked or bent ductwork, that cool air may not be able to reach your home. If your AC unit seems fine, you should check out the ductwork and see if there are problems there.

8. You Should Check Out Your Breakers

Sometimes, major problems have very simple solutions. Check your breakers and see if you can spot a blown fuse or a tripped circuit breaker. You could be able to get your AirCon running again in a matter of minutes.

9. Give Your Air Conditioner Some Time

AirCons don’t work instantly. If you’ve allowed your home to get very hot, it could take a long time to bring temperatures back down. If your home isn’t cool yet, don’t assume that your unit is failing. Wait a little while and see if the temperatures in your home start to drop.

10. You Might Need A Larger Air Conditioner

If you’re cooling your home with a window box unit, the size of the unit might be the problem. A lot of smaller units can only provide a limited amount of cool air. If you’re trying to cool a large apartment with a small unit, it might feel like your AC unit isn’t producing cold air at all.

Stand directly next to your AirCon and see if you feel cool. If your home feels warm, but you can feel cool air coming from your unit, you may need to use a larger unit. You can also try purchasing additional units. Use fans so that the cool air from the air conditioners is able to circulate throughout your home.

11. Your Air Conditioner May Have To Be Replaced

Nothing lasts forever — not even air conditioners. If your AirCon won’t run at all, and you can’t find the cause of the problem, it may be time for you to replace your unit.

Having to replace your air conditioner isn’t necessarily a bad thing. Although a new unit can be expensive, many newer units are more energy efficient than older models. After you replace your unit, you could see your utility bills drop.

Take a good look at your AirCon and see if you can get to the bottom of the problem. Whether you fix your air conditioner yourself or call a professional, you should be able to get your AC unit to start blowing cool air. Make sure you’re getting everything you need from your AirCon. Go over these troubleshooting tips and see if you can figure out what’s wrong.

Aircon servicing: How much maintenance work does an AC need?


Air-conditioning equipment requires regular maintenance service to operate at optimum levels for the whole year. It doesn’t even matter what type of air-conditioning system you employ, all of them need regular inspection, cleaning, and other maintenance work depending on its condition.

An AC unit that uses up cooling gas should also be inspected for the remaining volume. Doing so shall ensure that the machine doesn’t run out of coolant that helps cool the air and prevent it from running on empty which can damage the system.

Cleaning or replacing the air filter is a common service. You should know when the last time the filter was checked. It is also easy to spot a dirty filter because it is full of dirt and dust not retaining the translucent look of the filter.

Indoor coils should also be cleaned because it allows for the efficient movement of air in the space that it is cooling. You will notice better airflow immediately and the unwanted particles are also drained and excreted properly. However, this should be done by a professional to avoid damage to this important part.

Some air-conditioners have an outdoor coil such as the split-type air-conditioners. This needs to be cleaned because it not only improves the efficiency of your unit, but it also extends the service life of your machine. Blocked coils are easy to spot due to the visible accumulation of particles.

Condensation pumps should also be inspected because in many cases this is where a system failure begins. It accumulates molds and slime that should be totally cleaned to avoid irreparable damage to the system.

Routine inspections and cleaning have become very important nowadays because you want an AC to depend on especially during summers in Singapore.

Tips for maintaining your air-conditioner at home


Scheduled maintenance is a must for any home with an air-conditioning unit that runs regularly. However, there are also chores that you can insert in your routine that can really help prevent your home’s AC from breaking down.

Replacing Air Filters

Most AC’s have a reusable air filter that you can clean yourself. If your unit operates throughout most of the day, it would be best to have it cleaned each month. If you live in an area that has a lot of smog outside, it is also best to clean your filter every two weeks.

Dirty filters accumulate dust, dirt, and allergens affecting the flow of air inside your living space. Your kids might be allergic to dust or you might have allergic rhinitis that can get triggered because of the dust and particles that are getting blown together with the cool air.

Electrical wires

Checking wires can be done on your own you just have to know where it’s hidden inside your unit. Access panels are easily located, you can just consult the manual for your unit to find where it is.

Be sure that your unit isn’t connected to a power outlet to avoid electrocuting yourself. Once you’ve secured that part, it’s time to open the access panel which can be opened using tools like a screwdriver.

Look for blackened wires, pitting in the contactor switch, and other signs of overheating. If you have an electrical meter, you can use it to check the condition of the capacitors in your unit. These simple tests can be helpful in finding initial signs of a problem.

Thermostat check

A functioning thermostat allows you to cool your rooms at the right temperature. Many AC’s nowadays come with a programmable thermostat which is a convenient option because you don’t have to do any more hard turning unlike the early mechanical thermostats.

These devices can help you control the temperature throughout the day and schedule cooling times for your AC. It helps you save time and money because you don’t need to manually set the temperature and the right temperatures at the right time mean you’re not wasting energy which translates to the electric bill.

Fan Unit

Your AC has a fan unit that helps circulate the air in and out of your home. You must make sure that it’s running smoothly with no damage. Turn off your AC and do a simple inspection by looking at the fan in the cracks and maybe check the bearings for rust.

Outside units

For AC’s that have an external unit, there might be grass, dirt, and other organic materials that can get inside. It will clog up and cause damage to your external unit. You must make sure that there is empty space between your ACs external unit and your plants. Regularly trimming your garden will go a long way in keeping plant materials from entering your external unit.

Air Conditioner Servicing VS Aircon Overhaul Cleaning


Air conditioners that are not functioning properly will often require a professional air conditioning business to come out to do repairs. Sometimes it is only required to provide general servicing, but then there are other times where you will need an aircon overhaul cleaning service. These are very different services that are provided by or conditioning companies, each one doing very different things. It just depends on the condition of the air conditioning unit that you have, how long it has been since its last servicing, and what they believe will resolve the problem. Here is an overview of the differences between air conditioner servicing and aircon overhaul cleaning.

Reasons To Call In Air Conditioning Repair Company?

There are several reasons why people will contact one of these businesses to take advantage of air conditioner servicing or aircon overhaul cleaning. In most cases, it has to do with an air conditioning unit that has suddenly stopped functioning. Some of these businesses will offer emergency services, whereas others will only be able to come out to your location in the next few days. Let’s first look at the differences between the two types of cleaning services that you can take advantage of from local aircon repair companies.

What Is Air Conditioner Servicing?

When you get air conditioner servicing, they are going to look at several different things. They’re going to check the filter that is filtering the air that is coming into the system. They will look at the coolant to see if it is low, or if there is a leak. They will also consider looking at the fan belt which must be tight enough to make it turn properly. Other things they will look at will include the motor, lower, and will make sure that there are no problems with it connecting with the power supply. The problems they detect can be repaired relatively easily. Filters can be traded out, and belts can also be changed out if they are loose or if they are ready to break. However, if more extensive services need to be done, this is going to require aircon overhaul cleaning.

What Is Aircon Overhaul Cleaning?

This is a much more extensive form of cleaning. In the previous type of cleaning, they may have used a vacuum, or even chemicals, in order to complete the project. In this case, they are going to be much more intricate in the examination that they do of your air conditioning unit. They will look to see if the coolant is actually circulating properly, not just check to see if it is low. If the air conditioning unit is not turning on at all, they will do troubleshooting by looking at all of the internal circuitry. You may have blocked vents that are due to not just dust, but also toxic gunk that can build up over time. There could be drainpipes that are clogged, causing water to overflow, especially with the larger units. Evaporator coils can be damaged, prompting them to replace them. Instead of just looking at whether or not the fan is spinning because of the belt, they may actually look at the ball bearings within the fan mechanism to see if they are flattening out. These are all things that will occur during a full aircon overhaul, a much more time-consuming process. However, if it is a very expensive unit, one that would cost an incredible amount of money to replace, getting an aircon overhaul cleaning is probably the best choice for you.

How To Schedule One Of These Cleanings

The best way to schedule a cleaning is to look for a company that currently has several different options available. They may have different levels of cleaning services that they offer including both air conditioner servicing, or extensive aircon overhauling. Once they have completed either of these, your air conditioning unit should work fine. It just depends on how much damage there is, and how long it will take them to order the parts that may be necessary in order to complete the repairs.

You can easily find and air conditioning repair company that will provide you with the services. You can see all of the packages that they make available on their website. You should compare different companies to see how much they charge, and how extensive each of the cleaning services is, before deciding on one company over another. If you can find public feedback in the form of comments or testimonials, this can help you make your decision even more quickly. If you need their help right away, also consider using one of the companies that will offer you emergency services that may help you get your air conditioning unit running the same day if that is what needs to occur.

Why Air Conditioner Servicing Is So Important


Most people understand that they need to regularly service their air conditioner, but many of them do not understand why it is so important. There are a number of reasons why you should look at having your air conditioner regularly serviced. These reasons are particularly important if you live in a hot and humid climate such as Singapore.

Extending The Life Of Your Air Conditioning Unit

The primary reason why you should look at servicing your air conditioner is to extend its life. Regular servicing will find any issues with the unit before they become large problems. It also ensures that all aspects of the air conditioner are working correctly to properly circulate cool air.

Servicing will not only increase the overall life of the air conditioning unit, it will also reduce the repair costs that you face. Regular servicing will remove any dirt and dust which builds up over time and with use. When there is a large buildup, the unit will not be able to function correctly and multiple parts could start to wear which will result in large repair costs. In extreme cases, you may have to replace the entire unit.

Having Cleaner Air

While most people have an air conditioner to cool their home, there are other people who use them for the air purification function. Breathing clean air is vital to good health and you need to consider this when looking at the servicing of your unit. When you do not have your unit regularly serviced, you might not be getting good quality air.

As air conditioning units work with water to cool the air temperature, there is the chance that mould and bacteria can build within the dark recesses of the unit. If left unchecked, this mould and bacteria could enter the air in your home. Regular servicing will be able to identify any signs of mould or bacteria and remove them before they spread and become airborne. This will not only improve the air quality, it will also improve your health.

Preventing Water Leaks

One of the most common issues that people have with their air conditioner is that it leaks water. This often occurs when there is a buildup of dirt and dust in the unit. The passages that the water would generally travel will become clogged and there will be limited air circulation to remove excess moisture.

The exact cause of the water leak can vary from dust buildups to pipes within the unit breaking. Servicing your unit regularly will limit the cases of pipes breaking or a dust buildup. This can also reduce the chances of other complications that can come from a water leak such as mould.

Improved Efficiency

Most people are looking for a way to lower their energy bills, but in hot and humid countries, turning off your air conditioner may not be an option. If you are one of these people, you should look at getting an energy efficient air conditioner. These units will save you money as they do not use as much energy, but you will need to have them regularly serviced.

When you have your unit serviced, you are ensuring that it works as it should. This means that you ensure it is energy efficient and now wasting any energy. Units that do not get serviced correctly or regularly will start to use more energy and will increase your bills.

Abiding By Warranty Stipulations

There are a lot of people who do not realize that regular servicing of their air conditioning unit is actually a stipulation in the warranty. If you need to use the warranty at any time, the manufacturer is going to ask you about the service history of the unit. If you have not had your unit serviced regularly, you might not be able to use the warranty.

Of course, not all warranties have this stipulation. It is important that you find out if your unit’s warranty does have this stipulation. You do not want to be in a situation where you need the warranty only to find that it is void because you have not serviced the unit.

There are many reasons why regular servicing of your air conditioner is important. Not only will servicing identify any potential problems, it will also ensure that the unit runs correctly.

Tips To Save Money On Air Conditioning



There was a time when air conditioning was considered a luxury but these days, it has become a necessity. The air conditioning system keeps your home cool but it also results in huge energy bills. Many homeowners do not realize that they can quickly bring down their air conditioning energy costs with some simple things. So, follow the tips mentioned below in order to save money on your air conditioning energy costs.

One of the most important thing you need to do in order to lower your energy bills is to invest in proper maintenance of your air conditioning system. It’s recommended to get your air conditioning system serviced and cleaned at least once in a year in order to make sure it keeps running at peak efficiency. You should hire the services of a certified and reliable HVAC contractor to ensure that your air conditioning system is ready for the summer months.

If the air-conditioning system is not running at its peak efficiency, it will use more than required energy to provide the same level of cooling and that will cost you extra money. Ideally, you should get in touch with a licensed HVAC contractor before you turn on the air conditioning during the summer months. It is important that you do some research and hire an HVAC contractor who has experience with the type of air conditioning system you have in your home.

You should also consider investing in a programmable thermostat in order to bring down the energy bills. Without a programmable thermostat, you will always have to make changes manually and many people avoid making constant changes as it is uncomfortable. They do not realize that it also costs a lot of money in terms of higher energy bills. These days, Wi-Fi capable thermostats are also available that allow you to maintain the environment inside your home even when you are far away. So, do your research and invest in a programmable thermostat.

Experts recommend changing the air filters on the HVAC system on a regular basis. A dirty air filter is not only bad for your health but it also leads to increased energy consumption. In fact, dirty air filter also reduces the life of your HVAC system. Therefore, it is important that you regularly change the air filter.

It is also recommended to use the right sized filter. While air-conditioning will keep the temperatures down inside your home, you should also make use of window covering and shades in order to keep the radiant heat outside. It is also recommended to invest in energy efficient windows and doors to make sure cool air inside your home doesn’t escape.

You should also get the ductwork tested for airflow leakage. Proper sealing of ductwork has the potential to increase the efficiency of HVAC system by up to 20%. In other words, plugging any leakages in the ductwork can reduce your energy bills by up to 20%. So, get in touch with a reliable and experienced HVAC contractor in order to test the ductwork and seal any leakages.

Many homeowners are not aware that planting trees and shrubs all around their property can increase the efficiency of the air-conditioning system by up to 10%. In other words, a thing as simple as planting shrubs and trees around your property can bring down your energy bills by up to 10%. It is due to the fact that most heat that accumulates in a home is either due to the sun shining on the roof or through windows. By planting trees around the property, it will prevent the sun from shining directly inside the home which in turn will bring down your energy bills.

Proper air circulation inside the home is necessary in order to throw the hot air outside. In case you live in a multi-storey home, it is recommended to operate fans on the upper level and keep the windows open on the lower level. In case you have a one story apartment, it is recommended to close the windows near the fan and open the windows that are far away from the fan in order to keep the air moving. Proper air circulation will add to the cooling effect and will help you lower air-conditioning costs.

If your HVAC system is old, especially if it is more than 10 years old, it is recommended to invest in a new high efficiency cooling system. Technological advances in the recent years have increased energy efficiency of cooling systems and you should be able to fully recover the cost of a completely new cooling system through energy savings in a few years.

Overall, an air-conditioning system runs best when it is properly maintained. Therefore, you should ensure proper check and maintenance at least once a year. Regular maintenance will not only enhance the life span of the air-conditioning system but it will also keep it running at its most efficient. In simple terms, regular maintenance will save you a lot of money over the long run.
