Chris A.
I have recommended this company to everyone. They have a very professional staff, that are timely as well as respectful of your time and your home. Prices are very reasonable and the quality and service are amazing.
Robert B.
They came out right away and properly fixed my AC problem a month after the original AC company came out. Very professional and honest. They could have charged me double (which is what the original company did) and I would not have questioned it and would have gladly paid it. THANKS!
Keith S.
I generally don't post but will make an exception. ClimateSmith is the best HVAC contractor I've used in the 20+ years I've been in Atlanta. They installed a complete heat pump system and ductwork for a very challenging room to cool. Dependable, fair, honest, knowledgeable..highly recommended!
