Decatur isn’t a one-size-fits-all HVAC market. A 1925 Craftsman bungalow in Oakhurst puts very different demands on a cooling system than a 1990s ranch near Glenlake Park, and the humidity that settles into this part of Georgia between May and September punishes undersized or poorly sealed ductwork. Brandt HVAC handles both ends of that spectrum and everything in between, and we start every Decatur job with a written price before any work begins. Call (762) 465-4570 and a live person answers, any hour, any day.
Why Decatur Homes Are Different
Decatur’s housing stock spans nearly a century of construction styles, and that range shapes every repair and maintenance call we run here. The city’s core is dense with 1920s through 1940s Craftsman bungalows and Victorian-influenced houses, many still carrying original radiators and boilers. Those homes were built for coal-fired heat and open windows, not for central air, so when cooling gets retrofitted into them the work has to account for plaster walls, tight mechanical closets, and limited ceiling space for duct runs. Our technicians regularly work in Winnona Park and the streets around Agnes Scott College where a condenser has to sit on a narrow side yard and the air handler has to squeeze into a former linen closet.
Then there’s the climate itself. Decatur summers run hot and humid, with frequent afternoon thunderstorms that drive moisture into the air and into unconditioned crawlspaces. Mold and condensation on duct exteriors are real problems here, and a system that’s oversized will short-cycle and never pull the humidity down the way it should. Winter freezes are shorter but they stress older furnaces and aging boiler pumps, especially during the cold snaps that catch hydronic systems off guard. Decatur also has a high concentration of historic early-20th-century homes with hydronic heating and later-added air conditioning, which means the technician who shows up has to know both how a 1940s radiator loop behaves and how to integrate modern cooling into a house that was never designed for it.
Styles & brands we work with






Our Main Decatur Services
Most Decatur homeowners call us for two reasons: the air conditioner has stopped cooling, or the furnace won’t fire. These two services, plus the preventative maintenance that keeps both systems alive, each have their own dedicated Decatur page linked below.
AC Repair in Decatur
When a Decatur air conditioner fails in July, it’s rarely a single cause. It could be a capacitor that gave out after a string of 95-degree afternoons, a condensate line clogged with the algae that thrives in Georgia humidity, or a refrigerant leak that’s been slowly robbing the system of charge since spring. We diagnose the specific fault, put a written price in front of you before any work starts, and repair the system the same day in most cases. Read the full breakdown on our AC Repair in Decatur page.

Furnace Repair in Decatur
Decatur’s mild winters can lull homeowners into ignoring furnace issues until a January cold front hits and the system won’t ignite. Older homes here often have furnaces tucked into crawlspaces or basement corners where ignition problems, rusted burners, and failing thermocouples are common. In bungalows with original boilers, the trouble is often a seized circulator pump or air trapped in the radiator lines. Our Furnace Repair in Decatur page covers the typical repairs and what they cost.

AC Maintenance in Decatur
Humidity and pollen are the twin enemies of Decatur air conditioners. The same muggy air that makes your living room uncomfortable breeds debris on condenser coils, and the spring pollen season in metro Atlanta coats outdoor units with a fine yellow film that chokes airflow by June. A maintenance visit means cleaning those coils, checking refrigerant pressures, testing capacitors, flushing the condensate drain, and catching small problems before they become July emergencies. See what’s included on our AC Maintenance in Decatur page.

AfterPricing for HVAC Company in Decatur, GA
| Service | Typical range in Decatur |
|---|---|
| AC repair (diagnosis and common parts) | $150 – $650 |
| Furnace repair (igniters, valves, controls) | $150 – $700 |
| Full AC system installation | $3,500 – $7,500 |
| Seasonal tune-up | $80 – $200 |
What pushes a Decatur repair toward the high end of those ranges is usually access. A furnace wedged into a 30-inch crawlspace opening in an Oakhurst bungalow takes longer to reach than one in a full-height basement, and that labor time shows up in the final number. The other factor is age: the older the system, the more likely a repair requires a discontinued part or a retrofit component. Whatever the job is, you’ll see the total in writing before we start, and nothing gets billed that wasn’t agreed to upfront.
