"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."

"The technician was on time and courteous.  My A/C wasn't blowing any cold air, so he checked the air handler first, then checked the heat pump.  The freon was very low, 1.5 pounds in a 3.5 pound system, so he charged the unit with freon.  The air was fine after that.  He did a check for leaks from the evaporator coil "on the house" and showed me that the coil was losing coolant from several spots.  He recommended that an engineer come have a look about a system replacement since it was impossible to tell how long the coolant was leaking - the main issue being that the coil had several leaking spots.
Overall the service went well.  The price was a function of the high price of freon ($90 or so per pound), so it could have been any HVAC company getting dinged on the price issue.

"Yahav was the service technician that Clean Air Atlanta sent and he not only did a really great job on the work: he also saved us over $1000 by being HONEST about work our fireplace did not need, that another company had said we needed. I highly recommend this company!"

Heating and Air Conditioning questions, answered by experts

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.

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.

While both have advantages, a split system is generally cheaper than a ducted one. Because they are less invasive to install, the labor costs are lower, and they can be more energy efficient. But, a ducted system might be worth the investment if you run it more frequently. 

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

No, you don’t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.
