Furnace repair in Norcross typically runs $150 – $700 depending on the part and the furnace’s location in your home.

Call (229) 537-2086 and a live person answers, day or night, not a voicemail tree.

Norcross is our kind of town. Historic downtown storefronts sit next to 1980s-90s subdivisions, and the furnaces in those homes are now 25 to 40 years old. That’s where we spend most of our time here: hallway closets and attic installs with tight clearances, cracked heat exchangers, and blower motors caked with Georgia pollen. We know the streets, the building stock, and Gwinnett County’s permitting quirks. That local knowledge means a faster diagnosis and a repair that holds.
Why Dalton Heating & Air Alpharetta Is Norcross’s Preferred Furnace Repair Company
Homeowners in Norcross call us after a bad experience. A tech who quoted one price and charged another. A crew that never showed. A repair that lasted three weeks.

Every repair carries a written one-year guarantee. If the repair fails inside that year, we come back at no charge.

Furnace Tune Up in Norcross
A Furnace Tune Up in Norcross runs $80 – $200 and takes about an hour to 90 minutes, depending on the furnace’s location and condition. In Norcross homes, a tune-up means more than changing a filter. Our techs pull and inspect the blower wheel, check the heat exchanger for hairline cracks, test gas pressure at the valve, measure static pressure across the system, and verify the thermostat is calibrated against reality. For a hallway closet furnace with a 24-inch attic hatch above, access is half the job, and we plan for it before we arrive.
Most Norcross homeowners should schedule a tune-up in early fall, before the first real cold snap. Mild winters mean furnaces sit idle for eight months, and dust, pollen, and small debris settle into the blower assembly during that stretch. A tune-up catches failing ignitors, weak capacitors, and dirty burners before they become a no-heat call in January. The written report you receive afterward tells you what we found, what we fixed, and what’s likely to need attention next season.
What the inspection covers
We check every safety-critical component: the heat exchanger, the inducer motor, the gas valve, the pressure switch, and the flue. We also measure temperature rise across the heat exchanger to confirm the furnace is moving the right amount of air. If anything is out of spec, we show you the reading and quote a repair price in writing before touching it.
What it costs and what’s included
The $80 – $200 range covers the full inspection, filter change, and minor adjustments like thermostat calibration. If we find a worn part that needs replacement, you get a separate written quote. No tech on our team is paid on commission, so the recommendation is based on the furnace’s actual condition, not a sales target.
Emergency Furnace Repair in Norcross
Emergency Furnace Repair in Norcross is available 24/7, and most calls in the city get a technician on site within 60 – 90 minutes. When your heat quits on a cold January night or you smell gas near the furnace, you can’t wait until morning. We answer the phone live at (229) 537-2086, and we do not charge overtime just because it’s 2 a.m. The repair price falls in the same $150 – $700 range as any other furnace repair, written before we start.
Norcross winters are mild, but that doesn’t make a no-heat house comfortable. Nighttime lows dip into the 30s from December through February, and that’s cold enough to freeze pipes in a slab-foundation ranch with poor insulation. Emergency calls in Norcross usually involve a furnace that worked fine in November and died on the first truly cold night. That’s a failing ignitor, a stuck gas valve, or a pressure switch that’s given up.
What happens on an emergency call
The tech arrives, diagnoses the failure, and gives you a written price before opening the tool bag. If the repair is straightforward – an ignitor or flame sensor – most jobs are done in under two hours. If the furnace is unsafe to operate, we’ll tell you plainly and walk you through your options.

Safety first on every no-heat call
Furnace work involves gas lines, electrical connections, and combustion gases. A cracked heat exchanger can leak carbon monoxide into your living space, and that’s a serious health risk. We test for CO on every diagnostic call. If we detect a crack or other safety failure, we’ll shut the furnace down and give you a written repair or replacement quote on the spot.
Trusted Brands We Service in Norcross
We’re factory-trained on Carrier, Trane, Lennox, and Goodman, and we keep common replacement parts for these brands on hand in our service vehicles. Norcross homeowners with a 1990s Carrier 58B in a hallway closet or a Trane XR80 in an attic won’t wait a week for a part that has to ship from a warehouse. In many cases, we carry the ignitor, flame sensor, pressure switch, or gas valve we need to finish the job in one visit. When a part isn’t on the truck, our supplier network serves Norcross same-day for most common components.

AfterCommon Furnace Repair Problems We See in Norcross Homes
- Hall closet furnaces with shared walls against bedrooms. When the inducer motor starts whining under high static pressure, neighbors hear it through the wall. That’s a common call in Norcross’s denser subdivisions, and the fix is usually a new inducer motor plus airflow correction rather than a full replacement.
- Original 80% furnaces on slab foundations developing cracked heat exchangers. Years of thermostat recalibration masked oversized short-cycling, and the heat exchanger pays for it. We see this on 1980s-90s ranch homes throughout Norcross, and the repair often requires a legitimate replacement quote rather than a patch.
- Return air intakes pulling pollen and debris into the blower motor. Norcross’s tree canopy is dense in older neighborhoods near historic downtown, and by March, blower bearings fail from the accumulated dust and pollen. A tune-up in early fall catches this before the motor seizes.
- Attic furnaces with undersized access hatches. Many Norcross attics have 24-inch hatches, and a failed blower motor or inducer means a tech has to work in tight quarters. We know which homes this affects and we plan accordingly, bringing the right equipment to get the job done without cutting your ceiling.

FAQs About Furnace Repair in Norcross
Norcross noise ordinances restrict sustained mechanical noise in residential areas, and that matters when a furnace sits in a hallway closet against a shared wall. A failing inducer motor under high static pressure produces a whine that carries through drywall. The fix is a new motor and airflow correction to bring static pressure back to the manufacturer’s spec. Call (229) 537-2086 if your furnace is louder than it used to be.
A load calculation tells us exactly how much heat your home needs, and without it, any repair is a guess. In Norcross’s 1980s-90s subdivisions, original furnaces were often oversized by 30 percent or more, and years of short-cycling put extra stress on heat exchangers and blower motors. We reference the load calculation before recommending repairs on major components, so we don’t replace a part that’s the wrong size for the house.
Yes. Slab-foundation ranch homes in Norcross typically have the furnace in a hallway closet, attic, or utility room, and all are serviceable. Closet installs mean tight working space and careful attention to airflow, but they’re common and we do them weekly. Attic installs with 24-inch hatches take longer and cost more in labor, which is reflected in the $150 – $700 repair range.
A cracked heat exchanger doesn’t always smell. Sometimes you’ll notice a faint, lingering exhaust odor when the furnace runs; sometimes there’s no smell at all, which is why annual inspection matters. The real risk is carbon monoxide, an odorless gas. In Norcross homes with tight closet installations and shared walls, cracked heat exchangers are a safety hazard we flag immediately. If you suspect a crack, call (229) 537-2086 and we’ll test for CO on arrival.
A simple part swap like a blower motor, ignitor, or flame sensor does not require a permit. Gas valve replacement sits in a gray area depending on the scope, and full furnace replacement in Gwinnett County does require a mechanical permit. We handle all required permitting for the work we do. When a permit is needed, the cost and timeline are included in your written quote before work begins.
Call (229) 537-2086 for furnace repair in Norcross. A live person answers, the price is in writing before any work starts, and the repair is guaranteed for a full year. That’s how we do business here.
