Reasons why your AC is not cooling properly
It’s no fun when your air conditioner is not cooling properly on a sweltering afternoon, but it can happen. There could be many reasons why your AC is not working properly, ranging from a dirty air filter to something as serious as a bad condenser. Before you call your HVAC company, try to figure out what is causing the problem and see if it is something you can resolve on your own. Here are some of the most common reasons why your AC is not cooling properly:
Wrong size AC
If your air conditioner has been recently installed and does not cool properly, it is likely because it is too small or too small for the room. It is vital to choose the right size considering the size of the room, the amount of sunlight the room gets, the number of windows, and other factors.
Thermostat issues
The first thing to check when your AC is not cooling properly is your thermostat setting. It could be in “cool” mode, and the desired temperature should be lower than the current room temperature. If the settings are correct, check if the batteries need replacement (indicated by a malfunctioning thermostat screen).
Dirty air filter
If your AC is not cooling properly it could be because of dirty air filters. The air filter prevents dust, dirt, and other airborne particles from entering the air handler unit and keeps the components cleaner and working more efficiently. Over time, the air filter may become clogged and can block airflow.
This can reduce cooling and in worse cases, it can shut down the air conditioner completely. You can simply take out the filter and check how dirty it is. In case the filter is clogged, replacing it would do the trick. If the air filter is clean, but your AC still does not cool properly, you should look for other reasons.
Dirty coils
Condenser coils that are too dirty can prevent the ac from cooling your home properly. The condenser is the outdoor component of an air conditioner that is responsible for the condensation process that releases heat. If the condenser coil is dirty, it will not be able to dissipate heat outside, which will make the air conditioner less efficient.
Low/leaking refrigerant
Your AC uses refrigerant, a chemical compound that absorbs environmental heat and provides cool air once it runs through compressors and evaporators. R410A (also known as Puron) is the most commonly used refrigerant.
When the refrigerant level becomes low, the AC may have problems cooling your home. Low refrigerant levels could be due to undercharging during installation or a leak within the system.
Compressor problems
The compressor is the heart of your air conditioner. It transfers heat from the refrigerant to the condenser, the part that takes heat away from the air. It is one of the most important parts of your air conditioner. When it malfunctions, the system is unable to absorb heat from inside your home and transfer it outside, and the air conditioner cannot keep your home cool. Other signs of a faulty compressor include strange noises from the AC, a shaky outside unit, and the AC blowing warm air.
Age of the air conditioner
If your air conditioner is nearing the end of its operating life, it is unable to cool your home like before. Like any other mechanical equipment, the air conditioner also suffers wear and tear over the years and eventually needs replacement.
When the AC is near the end of its operating life and fails to keep your home cool, it is best not to waste time and money on repairs. If the old AC is not cooling properly, replace it before it shuts down completely.
In addition, if your AC is not cooling properly, electrical issues could be to blame. Faulty wiring or tripped breakers can disrupt the cooling process, causing discomfort in your space.
