"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

AC leaks are common, and an HVAC pro can usually fix them. You may be able to resolve some leaks on your own, but a professional HVAC technician should handle most AC leak repair. If left ignored, an AC leak could cause serious damage to your system or leave you with expensive water damage, usually leading to more costly repairs or replacements.

Replacing both an AC and a furnace takes a full day on average, ranging from eight to 12 hours. The process involves removing the old units, installing the new ones, and ensuring all connections are properly made. If both systems are being replaced simultaneously, it can take longer than installing a furnace alone, so plan accordingly.

Troubleshooting common issues with your AC often sheds light on a problem with the compressor. Signs that you need to replace a bad compressor include your AC blowing warm air, short cycling (turning on and off), making strange noises, and blowing less air overall. Since these problems can stem from several areas of your AC, always call a local AC repair team to confirm it's the compressor.

Fixing a leak in an AC unit costs $200 to $1,600, depending on the type of leak and any related damage. But depending on the age and condition of your AC, it might make more sense to replace the AC unit instead of repairing it. If your AC is only a few years old and relatively problem-free, then repairing it is the right call. But if it’s nearing a decade old and has other issues, consider replacing it.

If both your furnace and AC unit are more than a decade old, it may be a good idea to replace both of them. However, your furnace can last up to three decades, and your air conditioner can typically last up to 15 years, so consulting with a pro before deciding to replace both of them is best. If it’s before that time limit for each, you can fix many problems with repairs or just replace one.
