You might hear grinding or banging noises or smell something unpleasant and not realize it’s coming from your AC. Follow up on any unusual noises or smells. If your air conditioner is causing them, then something is wrong.
An air conditioner should remove humidity from the air as well as cool. If your house is feeling more humid than usual, this could mean there’s a problem with the AC.
Another symptom that you might not associate with your air conditioner is a sudden spike in your power bill. If it’s not due to an increase in usage or rates, it could mean your AC is running less efficiently.
The above symptoms could have several causes, including refrigerant leaks, thermostat issues, and dirty condenser coils. We’ll get to the bottom of your air conditioner malfunction and get your home cool again.
