"A giant shoutout to Atlanta Air Authority for coming to our rescue this week. We came home from being out of town on Sunday to a hot house. Our A/C unit was toast. Their quick response and fantastic service had us back up and running with a new unit within 3 days. Canâ t say enough good things about them. Definitely check them out next time you need HVAC service!!"

"I wanted to say a few things about this company. My other company sold to Dayco and this is my experience with the HVAC department. I called them because my upstairs unit was making a strange noise. Dakota came out and found the problem. He recommended what was needed and gave me an estimate. He was very professional. Later I spoke with Lane the service manager to ask a few questions. He was extremely helpful and also very professional. So, I will say that my first experience with Dayco was a very positive one. I would recommend anyone to give them a call."

"From the quote visit to the actual work, all the people were very knowledgeable and polite. I had multiple quotes and they were not only on par with the others I received but Guardian gave me alternative options. The gentlemen that worked my HVAC issue even took the time to pluck the little pieces of attic insulation out of the carpet that made it past the floor coverings they put down. So far so good and I am just happy that they were a no pressure outfit that seems to have gone above and beyond."

"They did exactly what they said they would do in our estimate and more. They even fixed an exhaust duct that had been damaged previously by another contractor. They ( Moises Garcia and his co worker) were on time, highly professional, did a fabulous job of clean up and it did not take as long to install as we thought it would. We are very happy with their work and our new HVAC system, it performs very well, so much better than the old system ever did."

Heating and Air Conditioning FAQs, answered by experts

It is possible to add air conditioning to an older home, but it can be very expensive to do so. Expect to pay anywhere from $6,000 to $17,000 or more for the ductwork and AC unit. You’ll also have to hack into the home’s walls and ceilings to add ductwork, which can impact the aesthetics of an old home.

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.

If your AC suddenly stops working, the first thing to check is your thermostat settings. Ensure the thermostat is set to the appropriate temperature and mode (cooling). Sometimes, a simple adjustment or replacing the batteries in the thermostat can resolve the issue. If that’s not the issue, look to see if the circuit breaker tripped. These basic checks can often identify simple fixes before you need to call for professional assistance.

Yes, you can potentially save $60 to $200 by handling your own air conditioner capacitor installation. However, capacitor replacement comes with the risk of electric shock. Only attempt this if you have the knowledge and protective gear to carry it out safely. Otherwise, we recommend hiring an HVAC pro with the experience to properly diagnose the issue and avoid damaging other parts of your AC unit.
