There are many reasons why your air conditioner might not be cooling correctly. It is important to know what the most common reasons why aircon is not cold are and how you can remedy this. Of course, there are some problems that you will not be able to fix yourself and will need to contact a professional to fix.
A Clogged Air Filter
One of the most common reasons for your air conditioner to not be getting cold is a clogged air filter. When the air filters are clogged, there will be limited air movement which reduces the cooling capacity of the unit. This is a problem that is easy to determine as you simply have to look at the filter.
If your filters are dirty or clogged, you will need to replace them. This is a simple task and you should be able to do this yourself. It is recommended that you check the instructions in the manual that came with the unit to ensure that you replace the filters correctly.
Another reason why your air conditioner might not be cooling is that the condenser coils may be dirty. The condenser coils in the air conditioner unit will help to dissipate the heat which has been removed from the air. The heat will be dissipated outside, but when the coils are dirty they will not be able to do this correctly.
The dirtier the coils in your unit, the less heat they will be able to remove. This will make it harder for the unit to cool the room and if the coils are very dirty, the unit will never be able to get cold enough. You can check if the coils are dirty, but it is recommended that you talk with a professional to clean them. If they are not cleaned correctly, the coils could be damaged and further affect the functioning of the unit.
Coolant is essential to the working of your air conditioner and if there is an insufficient level, your unit will not be able to cool correctly. Your coolant will need to be topped up at regular intervals, but this may have to be done more often if you are using the unit a lot. The manual that comes with your unit should have instructions about the coolant that your unit uses and how to top it up.
When you are topping up your coolant, you will need to ensure that you are using the right products. There are a number of different coolants on the market and some which, like R22, are being phased out. If your unit works on these coolants, you will want to look at alternatives as the supply will start to wane and the price of the coolant will rise in the coming years.
There are many reasons why your air conditioner might not be cold. Some of the common reasons for this will include clogged filters, dirty condenser coils and insufficient levels of coolant. You can remedy some of these problems yourself, but you will have to call a professional for others.
