Most furnace failures in Atlanta give you a warning before they quit: a rattle that wasn’t there last week, a burner that cycles on and off more than it used to, or a heat exchanger that’s been running hard through three winters of damp Georgia cold. If you need Furnace Repair in Atlanta, acting early can save you from a complete breakdown. By the time the house won’t warm past 62 degrees on a January night, you need a repair tech you actually know something about before they ring the doorbell. Brandt HVAC Co Atlanta has been repairing furnaces across Atlanta since 2003, and we do it with one rule that shapes everything else: you get a written price before any work starts, a written guarantee on every repair, and the name and photo of your technician before they arrive. Devin Marlowe leads our Atlanta team, and every tech who shows up at your door is background-checked, uniformed, and carrying a photo ID badge under the Threshold Verified standard. If your furnace is acting up in Atlanta, call (762) 465-4570 now. A live person answers, day or night.
Furnace Maintenance
Furnace Maintenance is what keeps a ten-year-old unit from becoming a $700 emergency in February. It’s a scheduled visit, not a response to a breakdown: our tech goes through the burners, the heat exchanger, the blower motor, the flame sensor, the gas pressure, and the condensate drain before anything fails. In Atlanta, where humidity creeps into every mechanical system, we also check for the corrosion that quietly eats gas valves and wiring harnesses. Brandt HVAC Co Atlanta charges $80 – $200 for a full furnace tune-up, parts not included if something needs replacing, and you’ll see the written price before we touch a screw. The best months for furnace maintenance in Atlanta are September through November, before the first real cold snap hits Druid Hills and Gresham Park and every HVAC company in the metro gets slammed.
Burner and Gas Pressure Check
An over-firing or under-firing burner is the most common efficiency thief we find in Atlanta homes. We test manifold gas pressure against the manufacturer’s spec, inspect the flame color and pattern, and clean the burners so they light evenly instead of starving or riching out. A furnace burning too rich can soot the heat exchanger; one burning too lean can cycle endlessly without satisfying the thermostat.
Blower and Airflow Inspection
A dirty blower wheel or a slipping belt (on older units) reduces airflow, which makes the furnace run hotter and longer than it should. We check static pressure, amp draw, and temperature rise across the heat exchanger. When airflow is right, the furnace uses less gas and the house warms more evenly from Fairburn to our Furnace Repair in Conley service area.
Styles & brands we work with
Heat Pump Repair
Heat Pump Repair covers the same compressor-driven system that cools your Atlanta house in July, running in reverse to pull heat from cold outside air in January. When a heat pump won’t switch into heating mode, the usual suspects are a failed reversing valve, a stuck defrost control, low refrigerant, or a thermostat that isn’t wired or programmed for dual-fuel operation. Brandt HVAC Co Atlanta figures out which one it is before we give you a number, and that number is always written down before work starts. Most heat pump repairs in Atlanta land in the $250 – $600 range, depending on whether it’s a contactor, a capacitor, a defrost board, or a reversing valve. If your heat pump is running but blowing lukewarm air, call (762) 465-4570 and we’ll send a tech with a name you know.
Defrost and Reversing Valve Diagnosis
When an Atlanta heat pump freezes up in winter and never defrosts, or when it runs in cooling while the thermostat calls for heat, the problem is usually the defrost board, the reversing valve coil, or the outdoor thermostat sensor. We test each one with a meter, confirm which part actually failed, and replace only what’s broken. No guessing, no loading the bill with spare parts.
Refrigerant and Compressor Testing
If the refrigerant charge is low, the heat pump can’t absorb enough heat outside to warm your house. We pressure-test the system, find the leak with an electronic detector or nitrogen, repair it, and recharge to the manufacturer’s spec. Compressor failure is the worst case, and we’ll only call it after ruling out every cheaper fix.
Heating Repair
Heating Repair is the broad label for any fix that gets warm air moving through your Atlanta home again: furnaces, heat pumps, package units, and the occasional boiler in older intown homes. It covers the common failures (ignitors, flame sensors, blower motors, thermostats, gas valves) and the diagnosing that tells you whether a niche issue is a $150 fix or a $700 one. Brandt HVAC Co Atlanta sends techs who carry stock for the brands you’re most likely to have in Atlanta: Carrier and Trane especially, which show up all over North Atlanta. Every heating repair gets a written price before we start and a written guarantee on the work when we finish. If your house in Fair Oaks or Decatur won’t warm up, our Furnace Repair in Decatur can help before pipes freeze. Call (762) 465-4570.
Ignitor and Flame Sensor Replacement
Most “no heat” calls in Atlanta come down to a dead hot-surface ignitor or a flame sensor so coated in carbon it won’t prove the flame. Both are small parts, typically $150 – $300 parts and labor, and both are quick to replace. We carry ignitors and flame sensors for the major brands on our trucks, so the job is usually done in one visit.
Blower Motor and Capacitor Repair
When the furnace fires but the air won’t move, the blower motor capacitor or the motor itself usually gets the blame. We bench-test the motor, check the capacitor’s microfarad rating, and for ECM motors, decode the fault codes instead of throwing parts at it. A failing blower in a humid Atlanta winter can drive up your gas bill noticeably before it finally dies.
Boiler Repair
Boiler Repair handles the hydronic systems that heat many of Atlanta’s older homes, particularly in neighborhoods like Druid Hills and North Druid Hills where radiators and baseboard heaters are still common. Boilers run on circulator pumps, zone valves, expansion tanks, and aquastats instead of blowers and heat exchangers. When one fails, you lose heat in one zone or the whole house, and the fix typically runs $200 – $700 depending on the part. Brandt HVAC Co Atlanta works on residential gas boilers, and we treat every boiler call with the same rule as furnaces: a written price before any work starts, and a tech who introduced himself by name before he touched the doorbell. Devin Marlowe’s team has seen enough failed relief valves and waterlogged expansion tanks around Atlanta to know what to check first.
Circulator Pump and Zone Valve Replacement
If one floor of your house stays warm while another stays cold, you probably have a zone valve that won’t open or a circulator pump that’s seized or leaking. We test voltage to the valve, check the pump’s impeller for free rotation, and listen for the hum of a stuck, overheated motor. Replacing either part gets heat back to the zone without disturbing the rest of the system.
Expansion Tank and Pressure Relief Inspection
Boiler pressure that climbs too high or relief valves that weep water are signs that the expansion tank has failed or the fill valve is overfeeding. We check the tank for waterlogging, verify the relief valve opens at its rated pressure, and reset the fill valve to the system’s operating range. This is the kind of problem that’s cheap to fix early and expensive to ignore.
Gas Furnace Repair
Gas Furnace Repair is the specialty that handles the natural-gas-fired equipment heating most of Atlanta’s single-family homes. These are the systems with burners, gas valves, pressure switches, draft inducers, and flame sensors all working in sequence. When one part in that sequence fails, the furnace either refuses to start or starts and shuts down on safety. Brandt HVAC Co Atlanta repairs all major gas furnace brands (Carrier, Trane, Bryant, and American Standard among them), and most Atlanta gas furnace repairs land between $150 and $700. The lower end gets you an ignitor or a flame sensor. The upper end gets you a gas valve, a control board, or an inducer motor. We’ll tell you which before you spend a cent.
Gas Valve and Manifold Repair
A gas valve that won’t open means no heat; one that won’t close properly means gas building up where it shouldn’t be. We verify inlet and outlet pressure, check the valve’s coil resistance, and confirm the board is actually sending 24 volts before we ever consider condemning the valve. If we replace it, the new valve gets tested under load, not just wired and walked away from.
Pressure Switch and Draft Inducer Checks
Flue safety switches are there to keep combustion gases out of your house. If the pressure switch fails, the furnace won’t fire. If the draft inducer motor is weak, the switch may chatter or open mid-cycle. We check the tubing, the port on the inducer housing, and the motor’s rpm and amp draw. A failed pressure switch is a relatively cheap fix, and we’d rather find that than watch you replace the board first.
Furnace Tune Up
A Furnace Tune Up is a preventive visit, plain and simple: we go through the heating system, clean what needs cleaning, tighten what’s loose, test what should be tested, and give you a written report of what we found. Brandt HVAC Co Atlanta prices furnace tune-ups at $80 – $200, and the work includes the things that actually matter in Atlanta’s humid climate: checking the heat exchanger for cracks or rust, testing the flame sensor’s microamp signal, lubricating the blower motor (where applicable), and measuring carbon monoxide in the flue. The tune-up is not a sales call. Our techs are not paid on what they sell, and you get a report in plain English, not a list of upsell codes. If we find something that needs fixing, you get a separate, written price for it.
Heat Exchanger and CO Check
Cracked heat exchangers are rare, but Atlanta’s humidity and years of thermal cycling do cause corrosion that can open a seam. We inspect visually and use a combustion analyzer to check for carbon monoxide in the flue gas and around the furnace. You’ll know exactly what we saw, including photos if anything looks questionable.
Filter, Condensate, and Safety Switch Check
A clogged filter or a backed-up condensate line will shut a furnace down faster than any failed part. We check the filter’s pressure drop, clear the condensate trap and drain, and test every safety switch (limit, pressure, flame rollout) to make sure they open and close properly. Most “no heat” calls in Atlanta could have been prevented with these simple checks.
Emergency Furnace Repair
Emergency Furnace Repair is for the nights when the temperature outside is dropping and the temperature inside is doing the same. Brandt HVAC Co Atlanta answers the phone with a live person 24 hours a day, 7 days a week. No voicemail, no callback queue, no automated phone tree. If your furnace dies on a Saturday night in Hapeville, Gresham Park, or nearby Forest Park Furnace Repair areas, you’ll talk to a human who can dispatch a tech to your address. Emergency calls don’t get an overtime surcharge. You’ll still get the same written price before any work starts, and the same written guarantee after it’s done. Most emergency furnace repairs in Atlanta run the same $150 – $700 range as regular repairs. Call (762) 465-4570 and we’ll get your house warm.
Carbon Monoxide and Gas Leak Response
If your CO detector is going off or you smell gas near the furnace, that’s not a repair call. That’s a leave-the-house-and-call-from-outside call. We will never tell you to troubleshoot a gas odor yourself. Once the gas utility has cleared the building and it’s safe to return, our techs can trace the source, repair it, and test the system for proper combustion and venting before you go back inside.
After-Hours and Weekend Dispatch
Atlanta doesn’t cool down politely, and January nights below 30 degrees are a real health risk for older adults and infants. Our after-hours team carries the same stock, the same diagnostic meters, and the same written-pricing policy as our daytime techs. A human answers, a tech gets sent, and you get the name and photo of the person who’s coming before they pull out of the lot.
Brands We Service
We repair every residential brand that shows up in Atlanta homes, including Carrier and Trane, which we see most often in North Atlanta neighborhoods. Our techs carry OEM ignitors, flame sensors, pressure switches, and control boards for Carrier’s Infinity and Comfort lines, and we don’t substitute aftermarket parts when the original part is the safer choice. Every Carrier furnace we touch leaves with a written guarantee on the work, whatever the age of the unit.
Bryant and American Standard are just as common in the older stock around Decatur, East Atlanta, and Hapeville. Bryant and Carrier share a parent company and a lot of internal components, so our techs who know Carrier boards know Bryant boards. American Standard is essentially Trane’s sibling brand, which means the blower motors, gas valves, and ignitors we stock for Trane fit most American Standard furnaces. Whether you have one of those or a Goodman, Rheem, Lennox, York, or Daikin, we can help. Bring the brand, bring the symptom, and we’ll bring a written price.

AfterSigns You Need a Pro Right Now
- The furnace fires and shuts off within a minute or two: This is called short cycling, and it usually means a flame sensor is failing to prove the flame or a high-limit switch is tripping. Leaving it unaddressed makes the burners and heat exchanger cycle through temperature swings they weren’t designed for.
- You hear a loud bang when the furnace starts: Often a delayed ignition caused by dirty burners or a weak ignitor. It’s alarming, and it’s also a sign that gas is pooling momentarily before lighting, which should be fixed before it gets worse.
- The blower runs constantly or won’t turn off: A stuck fan-limit relay or a thermostat that’s wired wrong can leave the blower running without any heat being produced. That wastes electricity and wears out the motor far ahead of its normal lifespan.
- You smell gas near the furnace or near any vent in the house: Leave the house, leave the doors open if you can, and call the gas utility from outside. Once the source is secured and the utility clears it, call us to find and fix the leak.
- The furnace is running but some rooms are 10+ degrees colder than others: That points to a duct issue, a failing blower, or a zoning problem. In Atlanta’s older homes, dampers and duct joints loosen with humidity cycles, and once one fails, the imbalance tends to get worse through the season.
Our Process, Step by Step
- 1
You call and a live person answers: Not a menu tree, not a callback. You’ll tell us what the furnace is doing, what neighborhood you’re in, and when you need us there. If it’s after hours, the same phone number (762) 465-4570 reaches a human.
- 2
You get a tech’s name and photo before arrival: We text or email you the name, photo, and background-checked Threshold Verified status of the technician assigned to your job. If anyone arrives who you weren’t told to expect, that visit is on us and we make it right. Devin Marlowe personally tracks every dispatch in Atlanta.
- 3
The tech diagnoses, then shows you the price in writing: We don’t give prices over the phone before we’ve seen the unit, and we don’t start work until you’ve seen the full written price and signed off. That’s non-negotiable. The diagnosis includes meter readings, error codes, and what was tested.
- 4
The repair happens with parts from our trucks: Our Atlanta trucks carry ignitors, flame sensors, pressure switches, capacitors, contactors, control boards, and gas valves for the major brands. Most repairs are completed on the first visit. If a part needs to be ordered, we’ll give you an arrival window, not a vague “sometime next week.”
- 5
You get a written guarantee before we leave: Every repair includes a written guarantee covering our work for 365 days. If it fails within that window, we return at no charge, no argument. The 365-Day Done Right Promise is in writing, on the invoice, every time.
How Much Does Furnace Repair Cost in Atlanta?
A typical furnace repair in Atlanta runs $150 – $700 depending on what failed. A hot-surface ignitor replacement usually lands between $150 and $300 parts and labor. A flame sensor cleaning or replacement runs $120 – $250. A draft inducer motor runs $350 – $650. A gas valve runs $300 – $600. A control board runs $350 – $700. Those are the numbers we see across Atlanta, from Fairburn to Conley.
What affects the price? The brand and age of your furnace, the part that failed, and whether the failure damaged anything else (a seized inducer can stress the control board, for example). What shouldn’t affect the price: the time of day, the neighborhood you live in, or how much the tech thinks you can spend. That’s why we give a written price on every job, before any work starts.
To avoid overpaying, get a diagnosis first, then a price. Never agree to a repair over the phone without a tech having seen the unit. And be wary of any company that refuses to show you the failed part or the test readings. Our estimates are free, and the price we quote in writing is the price you pay. If the scope changes, you approve the change in writing before we proceed.
