Bryant furnace repair in Marietta typically costs between $150 and $700, depending on the part that failed and how far into the sequence of operation the furnace gets before quitting. Most Bryant repairs in this area are completed in a single visit because the parts that fail most often – ignitors, flame sensors, pressure switches – are ones we keep stocked on the truck. As an independent Bryant service provider, we diagnose first, quote a written price, and don’t start a single bit of work until you have approved it in writing.

This page is for Marietta homeowners whose Bryant furnace is short-cycling, blowing cold air, throwing a fault code, or not lighting at all. If you want to know what’s actually wrong and what it will actually cost, call (478) 662-5175. A live person picks up, day or night.
How Bryant Products Fail – and How We Fix Them
- Bryant Evolution 90-series: hot surface ignitor failures. The silicon-nitride ignitors in these furnaces have a lifespan of roughly 7 to 10 years under normal run cycles, and Marietta winters, with their repeated cold snaps and thaws, accelerate the wear. The furnace will try to light, you’ll hear the gas valve click, and then nothing happens because the ignitor cracked. We replace these with OEM-equivalent nitride ignitors, not the cheaper carbide versions, because the board in the Evolution line is calibrated for the resistance curve of the nitride part. A mismatched ignitor can throw a false ignition-fault code and leave you with a furnace that behaves like the board is failing when it isn’t.
- Bryant Preferred 90-series: condensate pressure-switch nuisance trips. High-efficiency Bryant furnaces use negative pressure from the draft inducer to close a switch that tells the board it’s safe to light. When the condensate drain line clogs – which happens regularly in Marietta because of the red clay dust that settles in mechanical rooms – the switch opens mid-cycle and the furnace locks out. The fix is usually straightforward: flush the drain, clean the trap, verify the switch pulls correctly. But plenty of companies skip the trap and just replace the switch, which fixes nothing and costs you a service call that doesn’t stick.
- Bryant Legacy 80-series: blower-motor capacitor fatigue. The 80% efficient Legacy models are common throughout Cobb County, especially in the ranch homes east of Marietta Square. When the blower motor starts humming but the fan won’t spin, or the furnace heats up and then trips the high-limit because there’s no airflow, the capacitor is usually the culprit. We test the microfarad rating against the label before we condemn anything. In our experience on the Kennesaw Avenue corridor, about three of every five no-blower calls on the Legacy line come down to a $25 capacitor, not a $600 motor – and we’d rather sell you the $25 fix if that’s what the meter says.
- Bryant Evolution modulating gas valves: pressure regulation drift. Modulating furnaces lean on the gas valve to throttle, and when the valve’s internal regulator drifts out of spec, you’ll see the furnace short-cycling or the flame looking lazy and yellow at low fire. Some techs will tell you the valve is fine because the manifold pressure reads close enough. We don’t do close enough. We check gas pressure at both low and high fire against Bryant’s specs, because a valve that’s off at low fire throws heat-exchanger temps into range where condensation that shouldn’t be happening starts eating at the metal.
- Bryant two-stage heat exchangers: fatigue cracking near the inlet. In the older two-stage Bryant units – the ones that have been through fifteen-plus Georgia heating seasons – the thermal stress point is where the burner heat first hits the exchanger inlet. Marietta’s humidity doesn’t help; the rust accelerant in the air during our wet winters works on any micro-fracture. When we find a cracked heat exchanger, we don’t patch it. We shut the furnace down, show you the crack on our inspection camera, and walk you through your options honestly, including whether replacement makes more sense than repair on a unit that age.
Styles & brands we work with







Our Bryant Furnace Repair Process
- 1
You call, and a person answers. Not a phone tree. You tell us what the furnace is doing – or not doing – and we schedule a window. You get the technician’s name and photo before we arrive.
- 2
The tech arrives, badge first, and listens. Before any tools come out, we want to hear the sequence: what it does when it starts, what it sounds like, what you’ve already tried. On Bryant units, the fault code on the board tells us a lot, but your description tells us where to start looking.
- 3
Diagnosis, documented. We test methodically through the sequence of operation: thermostat call, inducer, pressure switch, ignitor, gas valve, flame sensor, blower. On an Evolution or Preferred unit, we pull the stored fault history from the control board – Bryant boards retain the last several faults, and that history often shows a pattern that a single test won’t.
- 4
Written price before any work. You see the repair cost in writing. Parts, labor, everything. No work starts until you approve the number. If a part can be OEM Bryant, we tell you the price difference. If a quality aftermarket part is the smarter call, we say so and explain why.
- 5
The repair, then the test. We fix it and run the furnace through a full cycle – not just one light-off. We watch it fire, run through a complete heat call, verify airflow and temperature rise, and make sure the burner flame is clean. Then we check that nothing else is waiting to fail.
- 6
The guarantee, written down. Every Bryant repair we do carries our written guarantee. If it fails within the coverage period, we return at no charge and make it right. That’s the 365-Day Done Right Promise. It’s printed, not promised verbally.

AfterWhat Bryant Furnace Repair Costs in Marietta
Furnace repair in Marietta runs from about $150 on the low end to about $700 for more involved work. Here’s how common Bryant jobs land:
- Flame sensor cleaning or replacement: $150-$250. A dirty flame sensor is the most common no-heat call on Bryant furnaces in this area. It’s a quick fix, and it’s the one we see most in the first cold snap of the season.
- Hot surface ignitor replacement: $180-$350. The part itself isn’t the bulk of the cost – it’s the diagnosis to confirm the ignitor is actually the failure, not a board or a gas-valve fault downstream.
- Pressure switch replacement: $200-$350. Includes verifying the inducer and condensate lines are clear, because a new switch won’t fix a clogged drain.
- Blower motor capacitor: $150-$300. Parts and labor included. We test first; we don’t sell motors when a capacitor is the problem.
- Control board replacement: $350-$700. This is where Bryant gets brand-specific, because Evolution boards require programming to match your specific model. We handle that setup on site.
- Gas valve replacement: $300-$650. We bench-test the old valve when safety allows and verify manifold pressure on the new one before we call the job done.
What moves the price: the specific part, the age of the unit and whether it’s modulating or single-stage, and whether the failure damaged anything downstream. We give you a written price before the work starts, every time. Call (478) 662-5175 and we’ll get a tech out to see what your Bryant actually needs.
Why Marietta Homeowners Call Brandt HVAC Co Marietta for Bryant Work
Most companies can put a part in a furnace. The reason people around Marietta Square and the neighborhoods off Whitlock Avenue call us is that they know exactly who is walking through the door before the door ever opens. Every Brandt HVAC technician is background-checked and identity-verified under the Threshold Verified standard. We send you the tech’s name and photo before the visit. At the door, we show a photo ID badge. If the person standing there doesn’t match who we told you to expect, that visit is on us, and we make it right. That’s the whole point of the name on the truck. Brandt comes from an old word for a firebrand – it’s a fitting name for the work of keeping a home warm.
We also work on the other major brands you’ll find in Marietta homes – Carrier, Trane, Lennox – which matters if your Bryant shares a home with a second system or you’re weighing repair against replacement. Devin Marlowe and our techs have logged enough service calls in Marietta to know which Bryant faults are weather-driven, which are age-driven, and which ones are quietly telling you the unit is done. We’ll tell you what we find, in plain language, with a written price and a written guarantee. Call (478) 662-5175 for a free estimate.
FAQs
No. As an independent Bryant service provider, we perform repairs that are compliant with manufacturer specifications, and we keep records of the parts and procedures on file. If your Bryant is still under the factory warranty, the furnace warranty covers the part itself; our labor warranty covers our work. We’ll tell you upfront which parts on your unit are still under factory coverage and which aren’t.
We use OEM Bryant parts when they are the right call, especially on newer Evolution and Preferred systems where the control board is calibrated to OEM specifications. For common wear items like ignitors and flame sensors, a quality aftermarket part from a trusted supplier often matches or exceeds OEM life at a lower price. We’ll show you both prices and let you decide, with our recommendation based on what we actually see on the bench.
We run same-day and emergency response in Marietta, and our phones are answered by a live person 24 hours a day, seven days a week. A no-heat furnace in the middle of a Georgia January cold snap isn’t something you should have to wait on, and you won’t get a voicemail when you call (478) 662-5175. We’ll schedule you as fast as our dispatch can get a tech to your door, and we’ll tell you the window honestly, not vaguely.
That depends on the part, the age of the unit, and the failure history. As a rule of thumb, if the repair is under $700 and the furnace is under 15 years old with no heat-exchanger damage, repair is usually the smart move. If the heat exchanger is cracked, or the unit is older and requiring its third major repair in two seasons, we’ll say so plainly and help you price replacement, including what a new system would save you in Marietta’s humid winters and sweltering summers. We won’t sell you a replacement because it’s more profitable for us. We’ll tell you what we’d do if it were our house.
We return at no charge and fix it. Every repair carries a written guarantee, and it’s covered by the 365-Day Done Right Promise. You don’t have to argue about it, and you don’t have to produce a receipt and hope. If the repair fails within the guarantee period, the return visit and the corrective work are free. That’s the deal, and it’s written on every invoice.
Ready to get your Bryant furnace diagnosed and fixed in Marietta? Call (478) 662-5175. A live person answers 24/7. We’ll get a tech out, find the real problem, and give you a written price before we touch a single screw. No guesswork, no upsell.
