10 Common AC Issues and Their Solutions

December 8th, 2022

Air-conditioning units which have not been used in a long time and units that are not regularly cleaned are more prone to damage and breakdowns. While some problems can be resolved using simple steps, some issues may require you to look for AC repair in Dubai.


Here are some of the most common AC issues and how to resolve them.

1. Restricted airflow/AC does not blow cold air

Dirt builds up whether you use your air conditioner or not. The build-up of dirt, dust and other particles on the filter not only restricts airflow but can ultimately damages the unit if left unattended. To avoid such problems, clean the filter regularly.

2. AC is not turning on

If the AC unit in your property is not turning on, check the thermostat batteries and replace them if they run out of charge. If the batteries and thermostat are fine, but the AC is still not working, check the circuit breaker. If the breaker tripped, you need to reset it.

3. Leaking water

Leaking water from your AC units is caused by various reasons, especially during summer. The leakage may be caused by a serious problem. If you are unable to identify the cause, it’s best to contact your trusted facility management company in Dubai to help resolve the issue.

4. Malfunctioning Thermostat

As mentioned above, checking, and changing the battery of the thermostat often solves the problem. However, if the thermostat is still not working properly, you may need to calibrate or upgrade it to make sure it gets the right temperature. You may seek help with services provided specializing in AC services.

5. Failure of Electric control

Turning the AC on and off frequently can cause the compressor and fan to wear out. Addressing this issue often requires emergency home maintenance as it involves wiring and electrical work. Contact your services provider or facility manager as soon as you can

6. Leaking ducts

A duct carries cold air to your home. Any leaks and holes in the duct can affect its function, making it seem like the AC is not on or does not work properly. To address this, look for holes or tears in the ductwork and check the airflow. Once you find the damage, seal the tear or hole using foil-faced tape.

7. Unpleasant smell

Mold growth may cause your AC to release a pungent or unpleasant smell. It is recommended that you perform regular AC duct cleaning or deep cleaning before using it again after a long time of dormancy. If the odor does not disappear, reach out to the facility manager.

8. Unusual noise

Like other issues, unusual noise coming from your AC unit is caused by a lot of things. To properly diagnose the issue or find the source of the noise, it’s best to contact the person in charge of facility management or find HVAC professionals who can do the work for you.

9. Circuit breaker tripping repeatedly

Several factors can cause your circuit breaker to malfunction or trip. Unlike other issues, there is no DIY solution for this. You need to call professionals as soon as possible to safely address the problem.

10. Damaged compressor

The compressor helps refrigerants carry out heat exchange and regulates AC pressure. Lack of lubrication, dirty coils and other factors can cause this. If your AC is not working properly, you can reach out to professionals to have it fixed. If the damage is extensive, they will advise you to change the compressor.
