Even with regular maintenance, it is common for problems to occur with your air conditioning system.

Whether your air conditioner is producing unusual sounds, or if it’s just not cooling the room enough, it is good to be aware of the issues it could possibly have.

Here are 10 common problems that you might have with your AC:

1. Dirty/clogged filters

Dirty or clogged filters are one of the most common reasons why air conditioners stop working properly. They reduce airflow and the quality of air is decreased significantly as well.

2. Drainage

Just like AC filters, drain lines can become clogged. Dust, dirt and lint build up over time, and the growth of algae can clog it too. If this happens, it can result in a leak, and that could cause problems with your AC.

3. Water leaks

Water leaks can be seen outside as well as inside.

If it is indoors, it is probably because the drain system has become clogged, forcing the water to go back up the pipe. If that is not the case, another reason could be that the condensate pump has broken down. In this case, the pipe needs to be replaced.

If there is a water leak outdoors, it can be due to dry air filters, a broken condensate pan, improper AC seal or even improper installation.

4. Fan failure

The fan located in the outdoor unit transfers the heat from indoors to outdoors. If this fan is not working properly, it will prevent proper heat transfer from taking place and reduce the overall efficiency of your air conditioner. Because of this, the AC’s compressor may overheat. As a result, it might even receive internal damage. If this does happen, you might have to replace your air conditioner.

5. Refrigerant leaks

An AC refrigerant is a coolant: it is responsible for cooling the air in the system. If it leaks, the unit will not be able to work properly. This will lead to the temperature fluctuating, and will lower the efficiency of your air conditioner. It is advised to get it checked by a technician.

6. Evaporator coils

Evaporator coils can become corroded, or they might freeze. A frozen evaporator coil can cause the entire system to freeze up and stop it from functioning. Regular maintenance is required to prevent this from happening.

7. Condenser coils

Condenser coils, which are located in the outdoor unit, can become dirty over time. Normally, they can be cleaned easily with water, but if its conditions are too bad, a technician needs to be called to clean it with a chemical cleaner.

8. Compressor

The compressor’s job is to apply energy to set the refrigerant in motion so that the heat exchange can take place. If it is damaged or has stopped working, your air conditioner will stop cooling your house.

9. Electrical problems

If you turn your air conditioner on and off too frequently in short periods of time, the compressor and fan of the system might eventually wear out. The compressor, condenser motor, and blower motor are connected. If the connection is disrupted because of corroded wires or the terminals, the compressor and motor might not turn on.

10. Thermostat

Your thermostat could be incorrectly calibrated and could be on the wrong setting. Make sure the inside of your thermostat is clean and that it is not being affected by direct sunlight.
