3 Reasons Why Your Air Conditioning System Could Malfunction

When it's working well, your air conditioning system distributes cooled air throughout your home to keep you comfortable during summer.

Unfortunately, several factors, including improper installation, inadequate maintenance and blatant disregard of early trouble signs can cause it to fail, leaving you at the mercy of the summer heat. By this time, you may need expensive repairs to get your AC system running properly again.

So, what are some possible reasons why your air conditioning system may stop working in a time of need? Read along to find out.

Dirty filter

One of the most common reasons for AC failure is relatively straightforward – a clogged filter. When your air conditioner's filter is dirty, it prevents air from passing through it freely. Consequently, the conditioned air coming from your AC system may be insufficient to match your residential cooling demand.

Thankfully, dirty filters are one of those AC issues that are easy to fix. All you need to do to restore the supply of cool air in your home is to remove and replace your dirty filter with a new one. If reusable, simply clean and reinstall it.

Dirty AC coils

Your air conditioning system has two sets of coils – one in the internal evaporative unit and the other outside. Clean AC coils are essential for maximising the performance and efficiency of your home's space-cooling system.

On the other hand, dirty coils will impede your system's ability to absorb and transfer heat from your home's indoor environment to the outside, reducing the cooling function and increasing the running cost of air conditioning.

If your AC system is malfunctioning because of dirty coils, cleaning the coils should help make the system run properly again.

Low refrigerant level

Your air conditioning system works by performing a refrigeration cycle – the process of removing heat from a space you want to cool. To facilitate this process, your system must have enough refrigerant.

While your air conditioner isn't designed to run out of refrigerant, leaks within the system can result in low refrigerant levels. When this happens, your air conditioner will lose its cooling ability.

If your AC system has a low refrigerant level, you'll need to detect and fix the leaks before regassing it to restore the normal refrigerant level.

Other factors, such as dirty fins, a frozen evaporator and a faulty compressor can also cause your air conditioner to malfunction. The good news is that AC contractors know the various issues you may experience if you neglect maintenance on your cooling system.

Don't hesitate to contact them for assistance with your air conditioning maintenance needs. Proper AC maintenance will help you avoid costly repairs down the road.
