"Very pleased with the finished work. Donny did a great job with everything, he really knows what he is doing. Put a new service entrance in, new breaker box in the basement, fixed up an old dryer plug and some new wiring. I have a few other smaller projects and he will be my go to guy. Thanks again Donny."

Heating and Air Conditioning FAQs, answered by experts

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

Unfortunately, a freon leak will persist even when your AC unit is off. The freon in the AC unit is under pressure no matter the status of the system, so it will continue to drip through the leak even when you shut off the entire unit. It will continue to leak freon until it’s completely empty.

Yes, but they don’t feel the same as an AC-cooled room. You’ll feel cool, moist air, opposite from an HVAC system that dries the air as it cools. Ventless units also have less tonnage than alternatives like ductless and central air, which means they aren’t as capable of quickly cooling large spaces or circulating cold air.

Most AC repair technicians will take between two and six hours to carry out repairs, depending on the work needed and the accessibility of the unit. For example, recharging refrigerant lines should take one to two hours to service, while replacing a compressor, blower fan, or other major components can take five to eight hours. You can ask your AC repair technician how long they expect the job to take, but just in case, you should plan on being home and available for most of the day.
