Furnace repair in Roswell typically costs $150 – $700, and most calls are diagnosed the same day. When your heat goes out in January and the temperature in your two-story off Holcomb Bridge Road drops into the 50s, you don’t need a website quiz, you need a technician who can get to you, find the fault, and put the price in writing before turning a wrench. Dalton Heating & Air Alpharetta dispatches crews into Roswell every weekday and weekend from our Atlanta metro office. Call (229) 537-2086 and a live person answers, 24/7.
Roswell’s housing stock is not one-size-fits-all. A furnace in a new build east of GA-400 wears differently than a unit retrofitted into a 100-year-old house off Canton Street. Our techs know both. That’s why we don’t pad a Roswell call with guesswork.
Key Takeaways

- Heat pump repair in Roswell falls in the $150 – $650 range.
- Every repair includes a written price before work begins and a one-year written guarantee.
- We service Trane, Lennox, and Goodman equipment, among nine major residential brands.

Why Dalton Heating & Air Alpharetta Is Roswell’s Preferred Furnace Repair Company
Dalton Heating & Air Alpharetta is a Garrison Partners company, founded in 2003 and run under The Garrison Standard. That means every Roswell call gets the same terms: a real arrival window, a written price before any work starts, and a written guarantee on every repair. If the repair fails within the guarantee period, we return to Roswell and fix it at no charge. That’s the 365-Day Done Right Promise, and it’s not an upgrade, it’s the default.
Our techs service the full mix of Roswell housing, from brick ranch homes in Mountain Park that still run original 1980s furnaces to historic properties near Canton Street with retrofitted central air in crawlspaces and attics. When you book a furnace repair, you’ll know the background-checked, uniformed technician’s name before they show up. No anonymous van in the driveway. No price that changes at the door.
Dispatch and scheduling are coordinated from our Atlanta office, but the crew you get lives with Roswell traffic, Roswell roads, and Roswell building quirks. That matters when a cracked heat exchanger is shutting down a furnace on a 25-degree night and the homeowner needs someone who knows that the shutoff valve is often behind a laundry closet in a split-level off Crabapple Road.
Heat Pump Repair in Roswell
Heat pump repair in Roswell is our Furnace Repair team’s most common cold-weather call, because so many Roswell homes use a single heat pump for both cooling and heating. When the reversing valve sticks or the defrost board fails, the system won’t switch from summer air conditioning to winter heat, and that’s exactly when you need it to work. The job usually involves testing refrigerant pressures, checking the reversing valve and defrost controls, and replacing whatever component has failed. Most heat pump repairs in Roswell run $150 – $650.
Reversing Valve and Defrost Board Work
A heat pump that blows cold air in heat mode often has a reversing valve that isn’t shifting. In Roswell’s humid air, defrost sensors also corrode faster than they would in drier climates. We test the whole sequence rather than firing the parts cannon at it.
Refrigerant Leak Diagnosis on Heat Pumps
Low refrigerant is not just a top-off, it’s a leak. Roswell’s pine pollen season clogs outdoor coils, and a clogged coil forces the compressor to run hot, which can accelerate leak points. We find the leak, repair it, and recharge to manufacturer spec, not to a guess.
Heating Repair in Roswell
Heating repair in Roswell covers gas furnaces, electric furnaces, and dual-fuel systems, and the failure patterns in this city change by neighborhood age. In the 1970s – 90s subdivisions west of GA-400, we see original gas furnaces with aging ignitors, failing gas valves, and heat exchangers that have been baked for 30 years. In older homes near Canton Street, we find systems that were never designed for the house they’re in. Heating repair work in Roswell generally runs $150 – $700, depending on what’s failed.
Ignitor and Gas Valve Replacement
A furnace that won’t light in Roswell is often the hot surface ignitor, a ceramic element that cracks after thousands of cycles. Gas valves also wear out and fail to open. Both are precise jobs: you confirm the gas pressure, verify the sequence, and replace with the exact part for the unit, not whatever is on the truck.
Blower Motor and Airflow Correction
Many older Roswell homes have blower motors that were undersized from day one, or ductwork that has leaked for decades. A constant-running blower or a furnace that trips its high-limit switch is usually an airflow problem, not just a motor problem. We fix the root cause and the motor if it’s damaged.
Trusted Brands We Service in Roswell
Our techs are factory-trained to service nine major residential HVAC brands, including Trane, Lennox, and Goodman. That’s important in Roswell because the city’s housing age means we’re working on everything from a 2003 Trane in a brick ranch to a newer Lennox in a rebuilt home near the Chattahoochee River. We stock common Trane, Lennox, Goodman, and Rheem parts on our trucks and can source less common parts from local suppliers the same day, which means fewer return visits and less waiting with the heat off.
Common Furnace Repair Problems We See in Roswell Homes
- Cracked heat exchangers in original 1970s – 90s furnaces. Years of running with clogged or undersized ductwork makes the blower motor strain and the heat exchanger run hot. Roswell’s older subdivisions on the west side of GA-400 produce this failure mode constantly.
- Furnaces short-cycling from oversized single-zone systems. Homeowners added rooms or finished basements and the original furnace was never resized. The system clicks off early, uneven heat spreads through the house, and components wear out fast.
- Control board failures after summer thunderstorms. Power surges in Roswell’s storm season damage ignition modules, and homeowners don’t find out until the first cold night when the furnace won’t fire.
- Starved return air in historic homes near Canton Street. Retrofitted systems in 100-year-old houses often have insufficient return air, which causes overheating, limit-switch trips, and short equipment life.

AfterPricing for Furnace Repair in Roswell, GA
We give every customer the price in writing before any work starts. No exceptions, no verbal estimates that shift when the tech gets to the truck. Below are the current ranges for Roswell.

| Furnace Repair | $150 – $700 |
| Heat Pump Repair | $150 – $650 |
What moves the number: the part, its age, and how accessible the furnace is. A furnace in a clean utility closet off the garage is a straightforward job. A furnace wedged into a crawlspace in a Canton Street historic home takes longer to reach and work on. Our estimates are free, they’re written, and they don’t change unless you add work.

Furnaces in Roswell’s Older Homes: The Duct and Panel Problem
There’s a pattern in Roswell that you won’t find in a blog written about heating repair in general. In the historic district near Canton Street, century-old homes often have furnaces retrofitted into cramped crawlspaces and attics, with undersized, leaky ductwork and insufficient return air. That’s rare in the newer subdivisions east of GA-400, where homes typically have modern, sealed duct systems. But west of GA-400, and especially in Mountain Park and along the older streets near the Chattahoochee, we walk into houses where the furnace is fighting the house itself.
We recently repaired a furnace in a brick ranch in the Mountain Park area. The original 1980s ductwork was leaking over 30 percent of conditioned air, and the return was starved. The heat exchanger, on a 20-year-old Trane unit, had overheated so many times it cracked and started tripping the high-limit switch. Our tech sealed the accessible duct joints, added a return in the hallway, and replaced the cracked heat exchanger. The family got through a January cold snap without a full system replacement, and the system runs cooler now. That’s the kind of fix that only happens when someone looks at the whole house, not just the part that failed.
Older Roswell homes also have electrical panels that weren’t built for modern HVAC loads. A 100-amp panel in a 1960s brick ranch can be maxed out before a technician even touches the furnace. We check the panel’s load and the wiring before recommending any repair that increases electrical draw. That’s not a sales pitch, it’s a safety check. A furnace that keeps tripping a breaker may not have a furnace problem at all, it may have a panel that’s been overloaded for years.

FAQs About Furnace Repair in Roswell
Short-cycling on the coldest days usually means an oversized furnace or restricted airflow is causing the unit to hit its high-limit safety switch early. In Roswell’s older subdivisions, we see this constantly because furnaces were installed when the house was smaller, then rooms were added without resizing the equipment or the ductwork. The fix starts with measuring static pressure and return air, not just replacing a control board. Call (229) 537-2086 for a diagnostic visit and a written price.
If the heat exchanger is cracked, the answer is usually replace, not patch. A cracked heat exchanger is a carbon monoxide risk and a repair rarely makes economic sense on a unit that old. But if the unit is otherwise sound and the issue is airflow, a repair can add years. We’ll tell you straight what the furnace needs and put both options in writing so you can decide. Call (229) 537-2086 for a free estimate.
Pollen clogs the outdoor condenser coil on heat pump equipment, which forces the compressor to work harder and can drive up energy costs all winter. Roswell’s high humidity also accelerates corrosion on electrical connections, flame sensors, and control boards. We clean coils and inspect circuitry as part of any furnace repair, not as an add-on upgrade.
That’s almost always a return-air or zoning problem. Single-zone systems in two-story homes push warm air upstairs but don’t pull enough back down, so the upstairs gets starved. In Roswell’s 1970s – 90s homes, undersized trunk lines and leaky duct junctions make it worse. We diagnose the airflow path first, then propose the fix. Call (229) 537-2086 for a diagnostic visit.
Call us first. The control board is the ignition brain, and if it’s fried from a power surge, the furnace won’t fire at all. Our Roswell dispatch is answered by a live person 24/7, and we carry common control boards on our trucks. We’ll tell you what to switch off safely while you wait and give you a straight arrival window. Call (229) 537-2086.
