Furnace repair in Atlanta typically costs between $150 and $700, and most failures we see are diagnosed in a single visit. If your heat is out in Midtown or you’re hearing a rattle from a closet unit in a 1950s ranch near North Druid Hills, you want a tech who knows Atlanta’s housing stock and the ways our weather abuses it. We run service calls across the city every day, and we answer the phone with a live person around the clock. Call (762) 465-4570 and you’ll get a written price before any work starts.
Atlanta’s humid subtropical climate means furnaces sit idle for seven months, then get hammered the first week of November. Rust, dust, dead insects, and the occasional mouse nest all accumulate in that off-season. When the first cold snap hits, we hear the same thing from Decatur to Forest Park: “It worked fine in March.” It usually did. The question is what happened since.
Why Brandt HVAC Co Atlanta Is Atlanta’s Preferred Furnace Repair Company
We’re not the cheapest outfit in Metro Atlanta, and we won’t pretend to be. What we offer is certainty. Every Brandt technician is background-checked and identity-verified under the Threshold Verified standard. Before your appointment, you get the tech’s name and photo. When they knock, they show a photo ID badge at the door. If anyone arrives who you were not told to expect, that visit is on us. Full stop.
Our Furnace Repair team works on Carrier, Trane, Lennox, and Goodman systems daily. We stock common parts for these brands at our Atlanta office, which keeps turnaround fast on ignitors, flame sensors, capacitors, and blower motors. No waiting a week for a part to ship from a warehouse in another state.
Devin Marlowe leads our Atlanta crew, and he insists on one rule above all: the customer sees a written price before the tool bag opens. Not a rough guess. Not a range whispered over the phone. A line-item price on paper. If you don’t approve it, we don’t do the work. That’s been the way since day one, and it’s why Atlanta homeowners who have been burned by open-ended invoices keep calling us back.
Every repair we make carries a written guarantee, and if that repair fails inside the guarantee period, we come back free. That’s the 365-Day Done Right Promise. It’s not marketing language. It’s a line in the contract.

Heat Pump Repair in Atlanta
Heat pump repair in Atlanta is a year-round need, because the same system that pushes heat out of your house in August pulls heat into it in January. In our climate, the outdoor unit gets hit hard: pollen coat in spring, thunderstorms in summer, and slick red clay mud in winter. A heat pump that’s losing refrigerant or carrying a weak capacitor will still blow air, but it won’t reach temperature. Homeowners notice it most on the first genuinely cold night, when the thermostat calls for heat and the air coming from the vents feels lukewarm.
Most heat pump diagnoses in Atlanta run $180 – $700, which includes the service call, the diagnostic labor, and the repair itself. If we find a major compressor failure or a burned-out reversing valve, we’ll quote the part and labor separately before you commit to anything.
There’s no maintenance contract required. No upsell pressure. The tech tells you what’s wrong, writes the number, and you decide.
Sinking Outdoor Units and Refrigerant Stress
In low-lying parts of Atlanta like Buckhead and Druid Hills, the water table sits high and the soil is heavy with red clay. We routinely find outdoor heat pump and condenser pads that have sunk inches into the ground over a few summers. That sinking stresses the copper refrigerant lines at the service valve. A slow leak develops. The system loses charge gradually, and one November morning it simply can’t transfer enough heat. The indoor coil never gets warm. The homeowner thinks the furnace is dead; the real problem is a refrigerant line that’s been under tension for three years.
We won’t just top off refrigerant and walk away. We’ll check the pad first. If it’s sinking, we’ll level it or pour a new one. Otherwise you’re back in the same spot next season.
Power Surge Damage on Heat Pump Controls
Atlanta summer thunderstorms are violent, and they don’t always wait for you to unplug things. A nearby lightning strike or even a utility line surge can send a spike through your heat pump’s control board. The compressor and fan may still run fine, but the thermostat communication gets scrambled. You’ll see error codes or a system that runs constantly without satisfying the setpoint. We replace control boards and surge-damaged capacitors routinely between May and September, then again when the first cold snap trips the system into heat mode and exposes the damage.
Heating Repair in Atlanta
Heating repair in Atlanta covers the full spectrum: gas furnaces, heat pumps, electric air handlers, and the occasional boiler in older intown homes. Most of our heating calls come in two waves. The first is late October, when homeowners fire up the furnace for the first time and discover the ignitor died quietly back in April. The second is February, when a cold snap holds the city under 20 degrees for four straight nights and systems that were limping along finally quit.
Standard heating repairs in Atlanta run $150 – $700. That range covers flame sensor cleaning, ignitor replacement, gas valve repair, blower motor diagnostics, and thermostat calibration. We’ll give you an exact number before we touch a screw.
Furnace Failure After the Storm Season
Atlanta’s thunderstorm season is brutal on furnaces. Power surges from lightning knock out control boards and blower motor capacitors, especially in older homes without whole-house surge protection. The furnace worked fine when you shut it off in March. Then a July storm sent a voltage spike through the line, the capacitor shorted, and now the blower motor just hums without spinning. You won’t know until November. We see this exact pattern in homes across Atlanta every fall.
The fix is straightforward: replace the capacitor, inspect the control board for burn marks, and test the full sequence of operation. It’s a $150 – $350 repair in most cases, and it takes under an hour.
Thermostat Wiring After Flooding
In crawlspace and utility-closet installs around Atlanta, thunderstorm flooding can leave low-voltage thermostat wiring soaked or shorted. Water finds its way into the spliced connections, corrodes the copper, and the furnace won’t respond to the thermostat even though power is restored. We trace the low-voltage path, replace the damaged section, and recalibrate the thermostat so your system isn’t short-cycling. That work typically lands around $150 – $400 depending on how much wire needs replacing.
Trusted Brands We Service in Atlanta
We work on all major residential furnace brands, but most Atlanta homes we visit run Carrier, Trane, Lennox, or Goodman. Our techs know the quirks of each. Carrier gas valves tend to fail on heat exchangers that haven’t been cleaned in years. Trane blower motors are workhorses but sensitive to voltage spikes. Lennox systems in Atlanta’s older homes often fight against undersized ductwork. Goodman units are common in the 1980s and 1990s subdivisions north of I-20, and their ignitors fail with regularity. Because we service these brands across Atlanta daily, we keep the common parts in local stock. A capacitor, flame sensor, or ignitor that would take days to order is often on our truck the same morning you call.
Common Furnace Repair Problems We See in Atlanta Homes
- Post-storm power surges. Lightning and utility spikes kill furnace control boards and capacitors. Older Atlanta homes without whole-house surge protection are the most vulnerable, and the damage hides until the first cold snap.
- Sinking condenser pads. Lots in Buckhead, Druid Hills, and other low-lying areas sit on high water tables. Pads sink, refrigerant lines stretch, and slow leaks develop that leave your furnace unable to reach temperature on the first cold night.
- Flooded low-voltage wiring. Thunderstorm flooding in shallow utility closets and crawlspaces short-circuits thermostat wires. The furnace stays dead even after power returns, and the homeowner is left standing in a cold house wondering what else is wrong.
- Clogged burners from summer dust. Atlanta furnaces sit idle for months while pollen, dust, and humidity work through the cabinet. First startup in fall often trips a dirty flame sensor or a clogged burner, leaving you with a system that fires and shuts off repeatedly.

FAQs About Furnace Repair in Atlanta
Check the main breaker and the furnace’s dedicated switch first; a power surge often trips the furnace breaker even when the rest of the house comes back on. If the breaker is fine and the thermostat screen is blank, the low-voltage transformer or a surge-damaged control board is likely the culprit. Don’t keep resetting the breaker repeatedly, as that can worsen damage. Call (762) 465-4570 and our tech will trace the fault from the panel to the board.
Dust that settled on the heat exchanger over seven idle months burns off during the first firing, creating a dry, dusty odor that should clear within an hour. If the smell persists or smells like plastic or gas, shut the system off and call us. Older Buckhead homes often have debris or even rodent nests near the heat exchanger, and that’s a safety issue we check on every first-start visit.
Yes. A sinking pad pulls on the copper refrigerant lines where they enter the outdoor unit, and that stress creates slow leaks at the service valve. The system loses charge gradually, and your furnace or heat pump loses heating capacity until one fall morning it simply can’t warm the house. We level or replace sinking pads before recharging, because a recharge alone won’t stop the leak from recurring.
A whole-house surge protector at your main electrical panel covers everything, but a point-of-use surge protector at the furnace disconnect adds a second layer for the control board. Atlanta’s thunderstorm frequency makes this a reasonable investment. We see far more furnace board and capacitor failures in homes without surge protection than in homes with it. We can install the protection during any repair visit. Call (762) 465-4570 for a written quote.
Never start a flooded condenser or furnace until a technician has opened the cabinet, dried the electrical components, and checked for corrosion on the control board and wiring. Water and electricity in a confined crawlspace pose a shock and fire hazard, and a wet control board can short out the moment power is restored. Call us. We’ll inspect the damage, determine what’s salvageable, and give you a written price before any restart attempt happens.
