Common Signs of AC Trouble

Common Signs of AC Trouble

With summer on the way, you'll want to make sure that your AC system is ready to beat the heat. When you first notice a symptom of AC trouble, it's best to call in an HVAC professional to conduct an inspection. Here are six signs of AC failure.

Poor Airflow

Weak airflow could mean that it's time for a professional cleaning of your ductwork. When debris is removed from your ducts, it'll be easier for air to flow like it's supposed to. But this could also indicate a mechanical problem, such as compressor trouble.

Doesn't Blow Cold Air

A dirty filter or faulty condenser fan could prevent cold air from reliably coming from your AC. This could also be an indication of a thermostat problem.

Increase in Energy Bill

If your AC unit is functioning inefficiently, then it could use more power as it struggles to keep your home cool. This might occur toward the end of an AC unit's lifespan.


If your AC is leaking refrigerant, this poses a health hazard and should be addressed ASAP. An issue with the condensate drain line could also lead to leaking.

Strange Noises

You might hear a squealing noise if there's an issue with the belt connecting the motor and blower. Whenever you hear strange sounds coming from your HVAC system, it's best to have a technician conduct an inspection.


A burning smell could be due to fried wire insulation, which creates a serious safety issue. If this occurs, you'll want to shut down your system and call in an HVAC professional. And if you notice a musty stench, then there could be mold/mildew building up in your AC unit.
