HVAC Company in Kennesaw, GA
About MR. HVAC
MR. HVAC is a family-owned company, and our licensed, certified technicians come to Kennesaw from our shop in Canton (7620 E Cherokee Dr). They handle residential service, commercial work and new construction with the same care. From a single repair on an older home to a full system for a new build, the goal is the same: equipment that runs right and a customer who knows exactly what was done.
Every visit starts by listening first, explaining the problem in everyday language and putting the repair price on paper before we touch a part. After 25+ years, that approach still brings customers back for their next tune-up, repair or system replacement.

Emergency AC and Furnace Repair in Kennesaw
Call MR. HVAC when the heat or air quits and the office team will take your information, ask a few quick questions about the system and send a technician with the right parts. You get the price before any repair starts.
Emergency service is available 24/7. If you smell gas or your carbon monoxide alarm sounds, leave the house and call 911 and your gas utility first.
Equipment Brands We Install and Repair
We install Goodman, Rheem, Carrier, Trane, Lennox and American Standard equipment and repair every major brand, including older systems that other companies will only quote for replacement.
When we quote a new system, we explain the efficiency and warranty differences between the options instead of pushing one brand.
Every new system is sized to the house, because an oversized unit wastes energy and an undersized one struggles on the hottest and coldest days.
Ask your technician which equipment fits your home and budget, and we will put the options side by side in writing.

- A written diagnosis and price before any work starts, with no hidden fees.
- Financing for new systems and major repairs. Subject to approved credit.
- New installations backed by the manufacturer's parts warranty, and we stand behind our installation work.

Kennesaw Heating and AC Questions
Q What happens during an AC repair visit in Kennesaw, GA?
The technician asks what you have noticed, inspects the indoor and outdoor units and tests the electrical parts, refrigerant pressures and airflow until the cause is confirmed. You get the diagnosis and a price in writing, then the repair, then a final test run.
Q How often should a furnace or heat pump be serviced?
Q Do you service HVAC systems in both older and newer Kennesaw homes?
Yes. Older homes often need duct repairs, better returns or electrical updates alongside the equipment, while newer homes usually need the right maintenance to keep manufacturer warranties valid. Our technicians adjust the service to the house and the system, whatever its age.
Q What should I do if my heating system fails during a cold snap?
Call MR. HVAC for emergency heating repair and tell the office what the system is doing: no airflow, cold air, or a furnace that tries to light and shuts off. If you smell gas, leave the house and call 911 and your gas utility first.
