AC Trouble: 6 Common Symptoms

AC Trouble: 6 Common Symptoms

With summer fast approaching, you need a healthy AC system to ensure that your family can stay comfortably cool. At the first indication of AC trouble, you'll want to call in a reputable HVAC expert who can accurately diagnose the problem and then return your unit to proper working order. Here are six signs of AC failure.


If you notice a leak around your AC system, it should be repaired as quickly as possible. This could be a refrigerant leak, which creates a health issue. Leaking could also occur due to a problem with the condensate drain line.

Fails to Reliably Blow Cold Air

When your AC fails to consistently cool your home to your desired temperature, you could be dealing with thermostat trouble. A dirty filter and bad condenser fan could also lead to this problem.

Spike in Energy Bill

AC problems could cause your unit to suck up more power as it struggles to keep your home cool. Consequently, your energy bills could climb.

Weak Airflow

Poor airflow could be a sign that your ductwork is in need of a thorough cleaning. By eliminating debris from your ducts, air will be able to flow more freely. However, weak airflow could also be caused by a mechanical issue, such as a compressor problem.

Strange Sounds

A squealing sound may emerge if there's a problem with the belt that connects the motor and blower. Anytime you hear strange noises coming from your AC system, you'll want to further investigate the matter.


Fried wire insulation could cause a burning odor. This poses a significant safety hazard. In this scenario, it's best to turn off your system and then call in an HVAC technician to conduct an inspection. Also, if you notice a musty smell in your home, it could be because of mold/mildew growing in your AC unit.
