"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

Absolutely! You can seriously improve the overall value of your home by maintaining high-quality, compatible systems for heating and cooling. Potential buyers will love not having to worry about getting a new HVAC unit for 15 to 20 years and will pay more for it. For maximum efficiency and cost savings, replacing the furnace and air conditioner at the same time, when possible, gives you (and potential future buyers) reliable comfort and modern convenience.

Unfreezing an AC unit is not a DIY project unless the problem is a dirty air filter. Changing out an air filter is easy for homeowners, but otherwise, trying to repair ductwork, refill refrigerant, or replace a blower fan motor are tasks best left to the pros. Otherwise, you could cause further damage to your cooling system or even harm to yourself.

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.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

While most air conditioners can last between 10 and 20 years, they will only last this long (or longer) if properly taken care of. Routine maintenance and inspections help keep your AC unit running in tip-top shape but understanding what factors will decrease its lifespan will also help keep your unit running cool.

Some things that shorten your AC’s lifespan include:

  • Extreme outdoor conditions, like high humidity or extensive salt spray 

  • Improper installation

  • Extended run times, either by the unit being too small or the thermostat setting too low

  • Not performing required maintenance
