6 Symptoms of AC Trouble

6 Symptoms of AC TroubleTo keep your family comfy and healthy during stretches of hot summer weather, you need your AC unit to reliably keep your home cool. At the first indication of AC trouble, you'll want to call in a professional HVAC specialist to conduct an inspection. Here's a look at six common signs of AC failure.

Foul Smells

Fried wire insulation could cause a burning odor. If you notice this symptom, you'll want to immediately shut off your system because of the safety hazard. If mold or mildew is growing in your ductwork or AC unit, you may notice a musty smell.


If moisture or liquid builds up around your AC unit/ventilation, then you'll want to determine what the underlying cause is. This issue could be indicative of leaking refrigerant, which creates a health hazard. With this symptom, a leaking condensate drain line is another possible concern.

Poor Airflow

Issues with airflow can potentially be resolved by getting a thorough duct cleaning. But it's also possible that a mechanical problem is present, such as an issue with the AC compressor.

Doesn't Blow Cold Air

Oftentimes, this means that your AC unit has failed and it's time for a replacement. But there's also a chance that this is a thermostat problem that can be fixed.

Increased Energy Bill

A faulty AC unit tends to draw more power as it labors to keep your home nice and cool. This can lead to a spike in your energy bill.

Strange Sounds

You'll want to schedule a professional HVAC inspection if your unit is making squealing or grinding noises. In many cases, such sounds are an indication that your unit is due for replacement.
