"Change came out the same day and accommodated prior supper commitments. He diagnosed the compressor issue quickly and methodically and made the repair. He checked the air temps and showed me the readings on his phone (ain't technology great?) and explained the equipment to an inquisitive grandson. The service call and parts were very reasonable. I was very impressed and remain so as the house is now quite comfortable. Great job and very good value!"

Heating and Air Conditioning questions, answered by experts

There are several AC unit problems to troubleshoot, but luckily you can identify them by keeping a close eye on your system. Look out for the following signs that your AC needs repair:

  • Unusual noises during operation

  • AC unit blows warm air

  • AC unit doesn’t come on or turn off with temperature changes

  • Strange odors come through the vents

  • AC unit cycles on and off rapidly

  • Indoor air is more humid or less comfortable than usual

  • AC unit keeps tripping your breaker

  • Fan in the outdoor compressor doesn’t operate when the AC is on

Don’t run your AC with a wet filter. It can cause your AC to work too hard, which will run up your utility bill and cause extra wear and tear on the system. You could also spread moisture and mold throughout your house. Turn off the AC, remove the wet filter, and check for cracks or clogs. Fix the problem (with a pro’s help, if you need it), and put a dry filter in place before you turn the system back on.

While spending money once or twice a year to tuneup your AC and furnace might seem like a waste of money, think again. The cost of HVAC maintenance is far less than the cost of replacing your furnace or AC unit, regardless of the type of HVAC system you have. Paying this smaller fee now will help you avoid paying much more significant costs in the future. Not to mention, having a serviced AC and heating system will help keep your home comfortable, no matter the season. 

Signs that your air conditioner capacitor is bad or failing include a range of symptoms. The AC unit may not turn on at all, or it might struggle to start before shutting down randomly or in the middle of a cooling cycle. You might hear a humming or banging noise when it attempts to start, or the compressor might hum without the unit actually running. Other indicators include a smell or smoke coming from the unit, the blower circulating room-temperature air instead of cold air, and an unexpected increase in your energy bills.

It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.
