"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

The cost to add Freon to an AC ranges from $100 to $350. It can increase up to $600 for large AC units requiring much more coolant. The cost also depends on how much refrigerant your unit needs. If only a small amount of Freon leaked out, your cost would be on the lower side. A complete replacement of all the required refrigerant can get expensive.

While it is possible to add Freon to your AC unit yourself, it is not recommended. In fact, the U.S. Environmental Protection Agency (EPA) prohibits the handling of Freon without a license. Freon is a dangerous gas that can cause irreversible damage to your AC or yourself if not installed correctly. It is worthwhile to hire a professional to add Freon to your AC.

You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.

Some AC filters, known as reusable filters, can be cleaned and reinserted. Most AC filters, however, are disposable and cannot be cleaned. 

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.
