Top 6 Reasons Your AC Breaks Down

Many of us have tales of our own of our AC breaking down while its 90 degrees outside. It can be a truly frustrating experience to have to bear with the heat when you should not have to. Here are some reasons why your air conditioner can betray you at the most inopportune times.


Your air conditioner is supposed to last up to 20 years or even longer. However, after about 10 years, you may start to see recurring problems, especially if you haven’t had the AC maintained recently. If you do not have it maintained regularly and your usage is high, don’t be surprised if your AC calls it quits.

Dirty Filter

Dust, dirt, and microbes can clog your air filters, causing your AC to only push out small amounts of cool air. It also forces your AC to work on overdrive, which leads to overheating and eventually, a broken down AC. To keep your AC functioning smoothly, change air filters every two months at least.

Dirty Condenser Coils

Your AC condenser coils get rid of the heat removed by expelling it outside, but if they get covered with a buildup of dirt, they won’t function properly. When that happens, they cannot release the heat outside, your unit has to overwork, and it can lead to system failure and break down.

Frozen Evaporator Coils

Your AC’s evaporator coils need warm air circulating through them to function properly. If they malfunction, these coils can get very cold and can build up a layer of frost on the outside. When that happens, your AC will issue warm air or nothing at all form the vents.

Refrigerant Leakage

If your AC develops cracks in the refrigerant lines, the gas will leak and the air form your AC will not be cooled. To fix this problem, you will need to get an HVAC professional, who will first fix the holes in the refrigerant pipe before refilling it with gas.

Fan Issues

Your AC has two fans; one that blows cool air into your room and another that expels the heat and humidity outside. These fans can malfunction because of a buildup of dirt, worn out belts, faulty motors or rusting. This can result in poor or no airflow. If left untreated, it can result in compressor failure which is the death blow for your AC.
