AfterHVAC Company in Dunwoody, GA
Most HVAC calls in Dunwoody aren’t about the equipment alone. They’re about ductwork cooked to 140°F in July attics, compressors suffocating behind azaleas the city won’t let you touch, and second floors that never cool because the original flex runs were sized for single-pane windows and R-19 insulation. We’re Brandt HVAC, and we handle the full picture: equipment, airflow, and the local conditions that break both. Dispatch runs from our Atlanta office; crews live and work in Dunwoody. Call (984) 538-9003 when you need us.
Why Dunwoody Homes Are Different
Dunwoody’s housing stock was built in a concentrated wave between the late 1960s and early 1990s, during DeKalb County’s suburban expansion. Those homes are now 35 to 55 years old, and a large share still run on original or first-replacement flex duct systems draped through unconditioned attics. That ductwork is the defining HVAC challenge here. Leaky, uninsulated, or undersized runs create chronic second-floor comfort complaints that a simple equipment swap won’t fix.
The climate doesn’t help. Dunwoody sits fully inside Atlanta’s humid subtropical zone, where cooling systems run six or more months under heavy latent loads. High humidity plus the city’s celebrated tree canopy means condensate drain lines clog with algae faster than in more open suburbs, and outdoor condenser coils accumulate leaf debris and seed pods year-round.
Then there’s the tree-preservation ordinance. Contractors often cannot clear vegetation around outdoor units. Homeowners routinely have compressors running in heavily shaded, poorly ventilated side yards that never get trimmed back, driving up head pressure and shortening compressor life faster than almost anywhere else in the metro.
Our Main Dunwoody Services
Homeowners in Dunwoody call us most often for cooling emergencies in July and heating failures in January. Each job type has its own page with full detail.
AC Repair in Dunwoody
AC repair in Dunwoody usually means a dead compressor on a 90-degree afternoon, a frozen coil from a clogged condensate line, or a capacitor that gave out after running overloaded all summer. We stock capacitors, contactors, and refrigerant for same-day fixes on most systems, and we always check the duct runs while we’re in the attic. A compressor replacement without addressing the airflow problem just burns up the next unit faster. AC Repair in Dunwoody
Furnace Repair in Dunwoody
Furnace repair in Dunwoody peaks in January when heat exchangers crack from years of short-cycling caused by those same undersized duct runs. We see a lot of failed igniters and dirty flame sensors on 15- to 20-year-old systems. Our techs test heat exchanger integrity on every gas furnace call, and we won’t patch a cracked exchanger. We’ll show you the camera footage, give you a written price for replacement, and let you decide. Furnace Repair in Dunwoody
AC Maintenance in Dunwoody
AC maintenance in Dunwoody is where we catch the problems before they become emergency calls. We clean condensate drains and treat them with algae preventative, pull and wash condenser coils clogged with oak and pine debris, and measure static pressure across those aging duct systems. If your flex runs are collapsing or your attic insulation has settled below the joists, we’ll document it with photos and a written report. AC Maintenance in Dunwoody
