When Do You Need an Air Conditioner Repair?

It is important to know when to fix your air conditioner. Some signs indicate you may need an air conditioning repair:

  • Unusual noises coming from the unit - If you hear grinding, squealing, or any other strange noises from your air conditioner, it’s time to call for a repair.
  • Weak airflow or poor cooling - If your unit is not blowing as much air as it should or if the air isn’t cool, you likely need a repair.
  • Water leaking from the unit - If you notice water leaking from your AC unit, it could be due to a damaged drain line or a refrigerant leak.
  • High utility bills - If your energy bills have suddenly increased, it could be due to an inefficient air conditioner that needs to be repaired.
  • Strange smells - If you smell anything strange coming from your air conditioner, it could mean there’s something wrong with the system that needs to be fixed.


Why is my AC blowing hot air instead of cooling?

Several reasons can contribute to this disturbance.

  • Incorrect setting of the thermostat.
  • Fan or compressor malfunction.
  • Leakage of refrigerant.
  • Clogged filter.

How can I tell if my AC compressor is malfunctioning?

By characteristic signs.

  • Instead of cooling - hot air.
  • Appearance of vibrations and unusual sounds.
  • Problems with the switching mode.

What should I do if my air conditioner is not cooling or is leaking water?

If your air conditioner is not cooling:

  • make sure the thermostat is set to the desired temperature and cooling mode; 
  • check the condition of the filters to make sure they are not clogged;
  • make sure the air ducts are not blocked.

If the air conditioner is leaking water:

  • make sure the air conditioner is properly installed;
  • check the drain hose: It may be clogged or blocked;
  • check if the condensate drip tray is full.

Why does my air conditioner emit strange smells or noises?

The most common odors are a musty smell and a burning smell. In the first case, it is caused by moisture and dirt accumulation in the air conditioner. Burning odor can be a result of a short circuit or overheating of the air conditioner.

What do strange noises indicate?

  • Hum - causes wear and tear on the compressor.
  • Grinding - problems with the fan.
  • Vibration - evidence of loose components.

When should I contact a professional for AC repair?

Professionals should be contacted:

  • if you cannot identify and eliminate the cause of the problem yourself;
  • if complex repair is necessary, for example, compressor replacement;
  • if you want to perform preventive maintenance on your air conditioner.
