When your furnace quits on a 35-degree Atlanta night, you don’t need a callback tomorrow. You need a technician at the door with the part, the price, and a repair that stays fixed. Cold Harbour Heating and Air Atlanta has repaired gas furnaces, electric furnaces, and heat pumps across Fulton and DeKalb counties since 2003, which means we’ve seen everything Atlanta winters throw at a heating system. Victor Mancini, our owner, built this company on one unwritten rule: the homeowner always knows the price before the work starts. Every repair we complete comes with our 365-Day Done Right Promise in writing. If the repair fails inside a year, we come back and fix it at no charge, no arguments, no second invoice. No after-hours voicemail, either. A live person answers the phone 24 hours a day, 7 days a week at (478) 223-8776. Most furnace repair visits in Atlanta run $150 to $700, depending on what’s actually wrong, and we’ll tell you the exact number before a single tool comes out. Our home service page has the full picture of what we do.
Furnace Maintenance
Furnace Maintenance is the scheduled service that keeps your heating system running clean and catches small problems before they become repair calls. In Atlanta, the furnace sits idle for most of the year, then works hard from November through February. That long idle stretch is exactly when dust settles on burners, belts loosen, and small cracks can start. Cold Harbour Heating and Air Atlanta offers Furnace Repair in Atlanta and services furnaces all year round, but the smart window for a tune up is September through mid-October, before the first real cold snap. A complete maintenance visit runs $80 to $200, which includes a full inspection, cleaning, and a written report of anything we find. You get the same technician every time, background-checked and in uniform, and the price is what you agreed to before we started. No surprise line items, no “while we’re here” upsells.
What We Check During a Furnace Maintenance Visit
Every maintenance visit starts with the heat exchanger, the safety switches, and the burner assembly, then moves through the blower motor, belt, and filter. We test the thermostat calibration and run a full cycle, checking carbon monoxide levels on gas furnaces. If something is wearing out, we show you the part and give you a price to replace it, but there’s no pressure and no obligation. You get a plain-English summary of what’s in good shape, what’s marginal, and what could wait.
How Often Your Furnace Needs Maintenance
Once a year is the honest answer for most Atlanta homes. If you have pets, old ductwork, or a furnace older than 15 years, twice a year is worth considering. The cost of a tune up is far less than the repair bill for a blower motor that seized because it never got lubricated. We’ll put you on a reminder schedule so you don’t have to remember.
Styles & brands we work with
Heat Pump Repair
Heat Pump Repair is what you need when the system that both heats and cools your home stops doing one of those jobs. A heat pump runs year-round, which means it wears out faster than a furnace that only works in winter. The strain is double, especially in Atlanta’s humidity. When a heat pump fails in heating mode in January, the house gets cold fast, and the outdoor unit often has frost building where it shouldn’t. Cold Harbour Heating and Air Atlanta technicians diagnose heat pump problems every week, from bad reversing valves to refrigerant leaks to failed defrost controls. Repairs generally run $150 to $700, and that’s the same price range whether the failure is in heating or cooling. Every repair gets our 365-Day Done Right Promise in writing before we leave.
Common Heat Pump Problems We See in Atlanta
The reversing valve, which switches the system between heating and cooling, is the most common part to fail. When it sticks, the heat pump blows cold air in winter or hot air in summer. We also see defrost board failures, where the outdoor coil ices over and can’t thaw itself, and refrigerant leaks caused by corrosion from Atlanta’s humid summers. None of these are do-it-yourself repairs. Refrigerant work requires EPA certification, and the electrical side is high voltage. Let us handle it.
Heat Pump vs. Furnace: What You’re Actually Fixing
If your home has both a furnace and a heat pump, the thermostat decides which one runs based on outdoor temperature. When the heat pump can’t keep up, the furnace fires as backup. That’s why a “heat pump problem” sometimes shows up as a furnace that runs constantly. Our diagnostic starts at the thermostat and traces the whole system so we fix the right part, not the symptom.
Heating Repair
Heating Repair covers any problem that stops your home from warming up, regardless of system type. In Atlanta, homes run on gas furnaces, electric furnaces, heat pumps, and the occasional boiler. Each one fails differently, but the homeowner’s experience is the same: cold rooms, strange noises, or a system that short cycles. Cold Harbour Heating and Air Atlanta repairs all four types, so the technician who arrives at your door can diagnose what’s actually in your house, not just what’s most common. Heating repairs in the Atlanta metro typically cost $150 to $700, with the final number depending on which part has failed and how accessible it is. We hand you the written price before work begins, and it does not change at the door. Call (478) 223-8776 any hour to schedule a heating repair visit.
Diagnostic Service That Finds the Real Problem
Our heating repair starts with a diagnostic visit, where we test the system end to end rather than guessing from the symptoms. A furnace that won’t start could be a thermostat, a pressure switch, a control board, or a gas valve, and each has a different price. We measure voltage, gas pressure, and airflow before recommending a fix. You’ll know exactly what failed, why it failed, and what it costs to correct.
Heating Repair in Older Atlanta Homes
Many homes in Decatur, North Druid Hills, and Gresham Park were built before modern furnace standards, which is why we offer our Furnace Repair in Decatur with technicians trained for older systems, which means tighter closets, older wiring, and sometimes asbestos wrap on old ductwork. Our technicians are trained to work safely in those conditions. If your furnace is in an attic or crawlspace, we bring the equipment to reach it and leave the area cleaner than we found it.
Boiler Repair
Boiler Repair is the service for radiators and baseboard heating systems that circulate hot water instead of forced air. Boilers are less common in Atlanta than furnaces, but homes in older neighborhoods like Druid Hills and Candler-McAfee still run on them. When a boiler fails, the problem is usually low pressure, a failing circulator pump, or an airlock in the lines. Cold Harbour Heating and Air Atlanta has repaired boilers across metro Atlanta since 2003, and our technicians know the hydronic systems in these older homes. Boiler repair runs $150 to $700 for most calls, and the 365-Day Done Right Promise covers every repair we perform. A live person answers when you call (478) 223-8776, day or night.
Boiler Pressure and Water Level Problems
Most boiler repair calls in Atlanta start with the pressure gauge reading too low or the expansion tank failing. When the system loses pressure, radiators go cold at the top or the whole system shuts down. We check the fill valve, the expansion tank, and the pressure relief valve, then correct the issue at the source. No boiler repair is complete without verifying the safety controls, because a boiler operates under pressure and can be dangerous if those controls fail.
Radiator and Zone Valve Repairs
Sometimes the boiler runs fine but one room will not heat, and that points to a stuck zone valve or air trapped in the line. We bleed the radiators, check the circulator, and repair or replace the zone valve as needed. The result is even heat through the whole house. These repairs are typically on the lower end of the price range, unless the circulator pump itself has failed.
Gas Furnace Repair
Gas Furnace Repair is what we handle most often in Atlanta, since natural gas is the standard fuel for forced-air heating here. A gas furnace that won’t ignite, won’t stay lit, or makes a banging sound when it starts has a specific problem that needs a trained technician. Gas and electricity are both involved, and we treat that combination with the respect it demands. Cold Harbour Heating and Air Atlanta diagnoses gas furnaces from the flame sensor to the heat exchanger, and our repair prices match the market range of $150 to $700. The price is in writing before we begin, and the 365-Day Done Right Promise means the repair is guaranteed for a full year. If it fails, we come back free.
Ignition and Flame Sensor Problems
The most common gas furnace repair in Atlanta is a dirty or failed flame sensor. The sensor confirms the burner is lit, and when it gets coated with carbon or corrosion, the furnace shuts down seconds after starting. We clean or replace the sensor, check the igniter, and confirm proper flame signal with a meter. This repair is typically on the lower end of the range.
Heat Exchanger and Carbon Monoxide Safety
A cracked heat exchanger is the repair every Atlanta homeowner hopes they never need, because it can leak carbon monoxide into the house. We inspect the heat exchanger on every gas furnace visit and use a combustion analyzer to confirm safe CO levels. If the heat exchanger is cracked, the furnace should be replaced rather than repaired, and we’ll walk you through the cost and financing without pressure. Safety is never a line item.
Furnace Tune Up
Furnace Tune Up is the proactive service that prevents most emergency furnace repairs in Atlanta. A tune up is less than a repair call, priced at $80 to $200, and it takes about an hour. During the visit we clean the burners, test the safety switches, check gas pressure, inspect the heat exchanger, and run the system through a full cycle. Cold Harbour Heating and Air Atlanta recommends one tune up every fall, before the first extended cold spell. Every tune up includes a written report with photos of anything we find, and the price is what you agreed to before we touched the system. If a tune up finds a problem, we give you the repair price separately, and you decide. No obligation, no high-pressure sales.
Why Fall Tune Ups Matter in Atlanta
Atlanta winters are mild compared to the Northeast, but furnaces here still work hard, especially January through March. The problem is that the system sits unused from April through October, and components dry out, gather dust, and small leaks go unnoticed. A furnace that runs fine in early November can fail as soon as temperatures drop. A fall tune up catches the loose belt, the weak capacitor, and the dirty sensor before they become a cold night emergency.
What a Tune Up Costs vs. What It Saves
An $80 to $200 tune up is cheap insurance against a $700 blower motor replacement. It also keeps your furnace running efficiently, which lowers gas bills through the winter. And if your furnace is still under a manufacturer’s warranty, some warranties require annual maintenance to remain valid. We keep a service record for you, and we’ll remind you when the next tune up is due.
Emergency Furnace Repair
Emergency Furnace Repair is available 24 hours a day, 7 days a week, because furnaces fail at the worst possible time. When your heat goes out at 2 a.m. and the temperature is dropping, you call Cold Harbour Heating and Air Atlanta at (478) 223-8776 and a live person answers. Not a voicemail tree, not an answering service that takes a message. A real person who can dispatch a technician to your Atlanta home that night. Emergency furnace repair in metro Atlanta runs the same $150 to $700 range as regular repair, and there is no overtime surcharge. You get the same written price before work begins, and the same 365-Day Done Right Promise when we leave. We do not charge emergency fees just because the clock says midnight.
What Counts as a Furnace Emergency
A furnace that stops making heat during a freeze is an emergency, full stop. Especially in Atlanta homes with infants, elderly residents, or people with respiratory conditions. A gas smell in the house is also an emergency: turn off the gas at the meter if you can, leave the house, and call us from outside or from a neighbor’s home. We respond to gas-related calls as quickly as we can and always prioritize safety.
Our 24/7 Atlanta Response Area
We dispatch from our Atlanta base and reach most homes within one to two hours, including our Furnace Repair in Smyrna service area. That includes College Park, Hapeville, Panthersville, and the neighborhoods around North Decatur. The phone rings through to a live person whether it’s a Tuesday morning or a holiday weekend, because the Kingswell Way says a cold house doesn’t wait for business hours.
Brands We Service
Carrier furnaces are among the most common systems we service in Atlanta, and we know their Infinity and Performance series well. Carrier uses proprietary fault codes that generic technicians often misread; we read them correctly and stock common Carrier OEM parts on the truck. Trane furnaces are built with a unique tubular heat exchanger that we inspect and service regularly across the metro. We see a lot of Trane units in North Druid Hills and Decatur, and our technicians know their gas valve and igniter assemblies inside out.
Lennox furnaces run quiet and efficient, but their variable-speed boards can be sensitive to Atlanta’s voltage fluctuations. We carry the boards and know how to test them properly. Bryant systems share a lot of DNA with Carrier, which means our Carrier expertise carries over directly. American Standard furnaces, a sister brand to Trane, show up all over College Park and Hapeville, and we stock their common wear parts. Whether you have one of those brands or any other make, we can help.

- Furnace turns on and off every few minutes. Short cycling means the system is shutting down to protect itself, usually because of overheating or a failed sensor. It drives up gas usage and will eventually kill the blower motor. This is a repair we handle daily in Atlanta.
- Banging, rattling, or screeching from the furnace cabinet. A banging sound at startup often points to delayed ignition in the burner assembly, which can crack the heat exchanger over time. A screech is usually a failing blower motor bearing. Both get worse the longer they’re ignored.
- Yellow or flickering burner flame instead of steady blue. On a gas furnace, the flame should burn clean blue. Yellow flames mean incomplete combustion, which produces carbon monoxide. If you see yellow, turn the furnace off and call us.
- Rooms heat unevenly, or some are cold while others are hot. Uneven heating across your Atlanta home often means a failing blower, a duct leak, or a system that’s too small for the house. We diagnose the actual cause and give you a written repair price.
- Pilot light or igniter won’t stay lit. If your furnace tries to start but the burners go out after a few seconds, the flame sensor or the gas valve is the likely culprit. This is repairable and usually on the lower end of the price range. The sooner it’s fixed, the less strain on the rest of the system.
Our Process, Step by Step
- 1
You call, a live person answers. There is no phone tree and no “leave a message.” We ask what the furnace is doing, confirm your address in Atlanta, and give you an arrival window. If it’s an emergency, we’ll move faster.
- 2
The technician arrives on time. Victor Mancini’s rule is simple: show up in the window we gave, or don’t give the window. Our technicians are background-checked, uniformed, and clearly identified. They’ll cover their shoes before walking through your home.
- 3
We diagnose before we quote. The technician tests the thermostat, gas pressure, airflow, and electrical components to find the actual failure. We use combustion analyzers, manometers, and multimeters, not guesswork. Then we write the price down and hand it to you. It does not change.
- 4
You approve the work, and we do it right. We repair the system using OEM or equivalent parts, then run a full cycle to confirm it’s working. We test CO levels on gas furnaces and verify the temperature rise across the heat exchanger. The job isn’t done until the furnace heats like it should.
- 5
We leave the guarantee in writing. Before we go, you get the 365-Day Done Right Promise on paper. If the same repair fails inside a year, we come back and fix it free. That promise is why homeowners in Smyrna, Redan, and all over Atlanta trust Cold Harbour Heating and Air.
How Much Does Furnace Repair Cost in Atlanta?
A typical furnace repair in Atlanta runs $150 to $700, but most calls land between $200 and $450. The exact number depends on what failed. A flame sensor replacement is usually $150 to $280. A pressure switch often runs $180 to $350. A hot surface igniter is $200 to $400 installed. A blower motor replacement, the big one, runs $450 to $700. A gas valve replacement falls around $350 to $600. Parts and labor are included in these ranges, and there are no overtime charges on emergency calls. Cold Harbour Heating and Air Atlanta gives you the exact price in writing before any work begins, so the number on the invoice is the number you approved. No surprises.
What affects the price? The brand of furnace matters a little, since OEM Carrier or Trane parts cost more than aftermarket. The age of the unit matters: older furnaces sometimes need additional work to meet safety codes. Accessibility is a factor too, because a furnace in a tight crawlspace takes longer to reach. How do you avoid overpaying? Get the price in writing before work starts, demand a detailed line item for parts versus labor, and make sure the repair comes with a written guarantee. A free estimate from us includes the diagnostic, the written price, and no obligation. If you want to compare, we welcome it. We’re confident in our work because we have to be: the 365-Day Done Right Promise means we eat the cost of our own mistakes.
