Since 1972 homeowners have chosen Reliable for fast, efficient and friendly AC Repair & Service. We have the largest residential heating and AC service team in the Chattanooga area with fully-stocked vans so you don't have to wait for repairs. Our technicians are experienced, knowledgeable and drug-free. We only hire the best of the best HVAC technicians! Our Customer First commitment is pervasive throughout the entire Company.

Reliable Heating & Air Conditioning Co. Inc. was founded in June of 1971. From its original staff of three, Reliable has grown to become Chattanooga's largest Residential HVAC Company, a respected Commercial service provider and winner of the "Small Business of the Year" for the State of Tennessee. As a second generation family-owned business, Reliable offers nearly a half-century of service experience to our customers. A third Generation of Cornell's is being trained to carry on the family tradition of Customer Delight.

Heat pump systems feature auto mode, which automatically switches between cooling and heating in response to the changing load in the space. Our ductless systems are nearly silent; their fans deliver air quietly and continuously with only a gentle whoosh for constant circulation and filtration. For this reason, Mitsubishi Electric split-zoning ductless air systems have long been the choice in thousands of homes, churches, schools, and libraries across the U.S. and the world. If you are looking for discrete zoned comfort, then a short-run ducted unit is the right solution.

Reliable Heating and Air Conditioning goes beyond selling, servicing, repairing and maintaining heating and air conditioning systems. We also make indoor air quality a priority. Reliable Heating and Air Conditioning has long been considered the leader in the tri-state area for handling all residential Indoor Air Quality needs. From steam humidifiers, high efficiency air filters and germicidal u.v. With so many options on the market to choose from, Reliable Heating and Air Conditioning has chosen to partner with Honeywell and their revolutionary IAQ team to bring you the latest and greatest in the ongoing battle to make your home comfortable, dust and germ free.

Jonathan S was fantastic. He was very competent and courteous. He went above and beyond what was required of him to finish his assignment.

This was our first maintenance service experience with Reliable Heating&Air and it was great! Cameron Scogg was the service tech and he was.

We had a great visit with Daniel that solved our AC problem quickly and in a very professional manner. Reliable is best in our area, no doubt
