HVAC Contractors Who Explain Before They Fix
About MR. HVAC
MR. HVAC is a family business that repairs, replaces and maintains cooling and heating equipment for houses, commercial spaces and new construction. Our technicians come to Dunwoody from our shop in Canton. On every call you hear what failed, why it failed and what the fix costs before any work begins, and nothing gets replaced without your approval. After more than 25 years of this work, our team is equally comfortable with a five-minute fix and a full system install.

Emergency AC and Furnace Repair in Dunwoody
When the air conditioner quits on a summer night or the furnace stops on a winter morning, call us. Our emergency line runs 24/7, and technicians arrive with parts for most furnace, AC and heat pump repairs.
If you smell burning or hear grinding, switch the system off at the thermostat and wait for the technician. 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.

Dunwoody Heating and AC Questions
Q Do you service air conditioners and furnaces in Dunwoody, GA?
Yes. Our work in Dunwoody covers air conditioner repair and replacement, furnace repair, ductless systems, air filtration and maintenance plans for houses and businesses. Technicians drive out from our Canton shop.
Q My AC uses R-22. Can it still be repaired?
Q What are the signs my furnace needs repair?
No heat or weak heat, flames that ignite and then die out, short cycling, a burning smell that lasts more than the first run of the season, or a yellow flame. Call us.
Q Is a high-efficiency system worth it?
It depends on how long you plan to stay and how much you run the system. Higher SEER2 air conditioners and higher AFUE furnaces cost more up front and save more each month; we show you both numbers so you can compare them.
