AfterFurnace Repair in Atlanta, GA
Furnace repair in Atlanta typically costs between $150 and $650 depending on the part that failed, and most calls we handle are diagnosed and fixed the same day. If your furnace is blowing cold air, short cycling, or making a sound you’ve never heard before, the first step is a diagnosis from a technician who will hand you a written price before any work begins. Cold Harbour Heating and Air Atlanta has handled furnace repair across the metro since 2003, and every repair we make is backed by a written 365-day guarantee. When the heat goes out in January and the temperature in your living room drops into the 50s, you don’t need a sales pitch. You need a real person on the phone and a technician who shows up when they said they would. That’s how we operate. Call (478) 223-8776 any time, day or night, and you’ll reach a live person, not a voicemail tree.
We’re the local Atlanta face of the Kingswell network, which means we follow The Kingswell Way: say the price before the work, show up in the window given, leave the place cleaner than found, put the guarantee in writing, and come back if the repair fails. You can read more about the full range of what we do on our Heating & Furnace in Atlanta page.

When You Need Furnace Repair
Atlanta winters are mild compared to Minnesota, but they’re damp. That moisture works its way into furnace cabinets, rusts burners, and corrodes electrical connections faster than dry cold ever would. Here are the most common situations where Atlanta homeowners call us:
- The furnace blows cold or lukewarm air. In most cases this is a failed igniter or a dirty flame sensor. Both are replaceable in one visit, and both are covered under our 365-day guarantee.
- The furnace short cycles, meaning it starts, runs for a few minutes, then shuts off before the house reaches the thermostat setting. This is often a clogged filter or an overheating limit switch, but it can also point to a failing blower motor. Homes in older neighborhoods like Kirkwood and East Atlanta, where ductwork is often undersized, see this frequently.
- You hear banging, rattling, or a high-pitched squeal. A loud bang on startup is usually delayed ignition, where gas builds up before the igniter lights. That’s a safety issue and worth a same-day visit. A squeal typically means the blower motor bearings are going.
- The furnace won’t start at all. This could be a tripped breaker, a bad thermostat, a failed control board, or a gas valve that isn’t opening. In older homes around Decatur and the greater Atlanta metro, we find a lot of control boards with corrosion from Georgia humidity.
- Pilot light issues on older furnaces. If you have a furnace with a standing pilot and the flame keeps going out, the thermocouple is usually the culprit. It’s a small part and a quick fix, but the symptom can also indicate gas pressure problems.
- Carbon monoxide detector is going off. This is the one that can’t wait. If your CO detector is sounding, leave the house and call the gas company first. Once the immediate safety issue is addressed, call us to inspect the heat exchanger and venting before running the furnace again.
Our Furnace Repair Process
We built our process around the idea that you should never have to wonder what’s happening, what it will cost, or when someone will show up. Here’s exactly how a furnace repair call works with Cold Harbour Heating and Air Atlanta:
- You call, a person answers. No phone tree, no “press 2 for service.” A live person takes your call at (478) 223-8776, asks what the furnace is doing, and schedules a visit with a firm arrival window. We serve the entire metro, from Buckhead down to the south side.
- A background-checked, uniformed technician arrives in the window. You know who’s coming, and we stick to the time we promised. Our techs are trained on nine major residential brands, including Carrier, Trane, and American Standard.
- Full diagnosis with a written price. The technician inspects the furnace, identifies the failed component, and writes down the exact repair cost before any tool comes out. That price is firm. If we find something else during the repair, we stop and show you another written price before going further. This is the Kingswell Way, not a courtesy.
- Repair completed and cleaned up. We do the work, test the furnace through at least one full heating cycle, and leave the area cleaner than we found it. Drop cloths come out. Filter debris gets swept up.
- Written 365-day guarantee handed to you. Before the technician leaves, you receive a written guarantee covering that specific repair for a full year. If the same repair fails inside 365 days, we return and fix it at no additional charge. This isn’t a verbal promise. It’s on paper.
Furnace Repair Pricing in Atlanta
We don’t hide behind “call for pricing” and we don’t play games with a low diagnostic fee that balloons into a high-pressure sales pitch. Here’s what furnace repair actually costs in Atlanta right now, based on the work we’ve done across the metro:
| Repair Type | Typical Cost Range (Parts & Labor) |
|---|---|
| Flame sensor cleaning or replacement | $95 – $180 |
| Igniter replacement | $150 – $280 |
| Pressure switch replacement | $140 – $260 |
| Thermocouple replacement | $120 – $220 |
| Capacitor replacement | $110 – $220 |
| Blower motor replacement | $380 – $700 |
| Control board replacement | $300 – $650 |
| Gas valve replacement | $250 – $550 |
| Heat exchanger replacement | $900 – $1,800 (often a replacement makes more sense) |
What drives the cost is the part itself, how accessible it is inside your furnace, and whether we’re dealing with a high-efficiency condensing unit or a standard 80% furnace. A Bryant or Carrier unit installed in the last decade will usually have readily available parts. An older Goodman or Trane from the early 2000s may need a part that’s harder to source, which can push the price up.
Every quote we write includes parts and labor. There’s no separate “trip charge” added on top of the repair price, and no surprise fees at the door. Estimates are free. Call (478) 223-8776 and tell us what your furnace is doing. We’ll give you an honest range over the phone and a written price on site before any work begins.
Repair or Replace?
If your furnace is under 12 years old and the repair is under $500, repair almost always makes sense. If the heat exchanger has failed, or if the unit is 15-plus years old and the repair exceeds half the cost of a new furnace, we’ll tell you straight. We won’t push a replacement when a $200 igniter fixes the problem, and we won’t sink your money into a dying furnace just to bill a repair. That’s the kind of honesty the Kingswell standards demand of us.
FAQs – Furnace Repair
How much does furnace repair cost in Atlanta?
Furnace repair in Atlanta typically runs $150 to $650 for most common fixes like igniters, flame sensors, pressure switches, and blower motors. Heat exchanger replacement is the exception, ranging from $900 to $1,800. Every price we write includes parts and labor, and you receive a written estimate before any work begins. Call (478) 223-8776 for a free estimate specific to your furnace.
Can you fix my furnace the same day?
Yes. In most cases we diagnose and repair the furnace in a single visit because our trucks are stocked with common parts for major brands including Carrier, Trane, and American Standard. Call early in the day and a technician can typically be at your door within a few hours, with a firm arrival window given when you book.
Do you guarantee your furnace repairs?
Every furnace repair we make carries a written 365-day guarantee. If the same repair fails within one full year, we return and correct the work at no additional charge. The guarantee is printed and handed to you before the technician leaves, not buried in fine print.
Is it cheaper to repair or replace a furnace?
Repair is cheaper when the furnace is under 12 years old and the repair costs less than half the price of a new unit. Replacement makes more sense when the heat exchanger has failed or the furnace is past 15 years with a major component gone. We’ll show you the numbers and let you decide, without pressure either way. Call (478) 223-8776 and we’ll walk you through the math honestly.
What brands do you service?
Our technicians are trained to service nine major residential HVAC brands, including Carrier, Trane, Bryant, American Standard, Lennox, Goodman, Rheem, York, and Daikin. Whatever is in your home, the technician who shows up can work on it.
Do you charge for estimates?
No. Estimates for furnace repair are free, and the written price you receive before work begins is the price you pay. There are no hidden fees, no trip charges stacked on top, and no changes at the door. That’s a core part of the Kingswell Way.
