We’re Brandt HVAC, an HVAC company serving Roswell, GA, and the neighborhoods around it. Roswell work is different from the metro average: you’re dealing with 19th-century mill village homes along the Chattahoochee, mid-century ranches, and whole subdivisions built between 1980 and 2010. Each of those needs a different approach to heating and cooling, and most of them are fighting Georgia humidity and spring pollen at the same time. Roswell’s three main services have their own pages, linked just below. Call (478) 662-5175 and a live person answers, day or night.
Why Roswell Homes Are Different
Roswell’s housing stock spans roughly 180 years, and the split is unusually sharp. In the historic district near Canton Street and along the Chattahoochee, you’ll find homes with original pine floors, plaster walls, and no ductwork at all. Those jobs rarely allow conventional central-air retrofits; the practical answer is often a high-velocity mini-duct system or ductless mini-splits, which means smaller wall openings and less damage to original trim. In the larger subdivisions that went up from the 1980s through the early 2000s, the homes usually have central systems from the start, but many of those systems are now 15 to 20 years old and were sized for cooler summers than Roswell actually gets.
Roswell’s climate is humid subtropical: hot, muggy summers and mild winters that still produce cold snaps. That means cooling does the heavy lifting, and humidity control matters as much as temperature. Spring pollen is another Roswell-specific problem – cottonwood and pine pollen clog outdoor condenser coils quickly, which is why a spring cleaning here is not optional. A unit with a fouled coil will run longer, cool less, and cost more to operate. Many older Roswell homes also have original insulation levels that make the system work harder than it should.

Our Main Roswell Services
The three services Roswell homeowners call us for most, with a local breakdown of each:
AC Repair in Roswell
Most Roswell AC failures follow a pattern: a condenser coil packed with spring pollen, a refrigerant leak that got worse through the first heat wave, or a capacitor that aged out under heavy cooling loads. Older homes in Roswell’s historic district often pair aging air handlers with newer outdoor units, and that mismatch creates its own strain. We diagnose the problem, put a written price in front of you before any work starts, and stock parts locally for faster turnaround. Full details on the AC Repair in Roswell page.
Furnace Repair in Roswell
Roswell winters are mild enough that furnaces get ignored for months, then pushed hard on a 25-degree morning. Igniters, flame sensors, and blower motors are the common failures we see, and many Roswell furnaces are located in crawlspaces where Georgia humidity speeds up rust and corrosion. Every repair includes a written guarantee, and if it fails within the guarantee period, we return at no charge under our 365-Day Done Right Promise. Details here: Furnace Repair in Roswell.
AC Maintenance in Roswell
Given Roswell’s pollen load and humidity, a yearly tune-up is the cheapest insurance you can buy on a cooling system. We clean the condenser coil, check refrigerant pressures, test the capacitor, and confirm the drain line is clear before the first big heat. A spring visit catches most issues before they become a July emergency, and you get a written report of exactly what was found. See AC Maintenance in Roswell for what’s included and what it costs.

What moves a repair toward the high end in Roswell is usually the home itself: older ductwork that complicates access, a system that’s been retrofitted, or a crawlspace location that adds time to the job. But the price you’re quoted is the price you pay, and it’s in writing before a tool comes off the truck.

Most Roswell repair work does not require a city permit, but installations and major equipment changes often do. Our technicians know the local requirements and handle the paperwork when it’s needed.
Yes. In the historic district, where original floors and plaster make big ductwork changes tough, we lean on high-velocity mini-duct systems and ductless mini-splits that respect the original structure while still delivering proper cooling and humidity control.
