Fast, Reliable Furnace Repair Across Duluth
When your furnace quits on a cold Duluth morning, you need a straight answer: what’s wrong, what it costs to fix, and who’s coming to your door. Most furnace repairs in Duluth run $150 – $700 depending on the part, and our techs carry the most common replacement components on the truck so a no-heat call is often resolved same-day. Dalton Heating & Air has been holding our crews to The Garrison Standard since 2003: written pricing before any work starts, a written guarantee on every repair, and a live person answering the phone 24/7. Call (361) 306-9515 and you’ll get Marco Benitez’s team, not a voicemail queue.
Why Dalton Heating & Air Is Duluth’s Preferred Furnace Repair Company
Duluth homeowners call us because they’ve been burned before, by a tech who didn’t show, a price that changed at the door, or a repair that failed in three weeks. We don’t play that game. Every job, from a $95 igniter swap to a full heat exchanger diagnosis, gets a written quote before we touch the unit. If the repair doesn’t hold, we return free. That’s the 365-Day Done Right Promise, and it’s not an upsell, it’s the default.
Our techs know Duluth’s housing stock. They know the 1990s subdivisions off Peachtree Industrial Boulevard where flex duct gets kinked and static pressure climbs. They know the older Gwinnett County homes near Buford Highway where furnaces get sized by square footage instead of load calculation. That local knowledge changes the diagnosis. A furnace short-cycling in a tight-build Duluth subdivision might not need a new board, it might need the thermostat calibration checked and the filter situation fixed.
Dispatch and scheduling are coordinated from the brand’s Seattle office; crews serve Duluth locally. When you call, a real person answers, takes your address, and schedules a background-checked, uniformed tech inside a stated window. No callback roulette.
Gas Furnace Repair in Duluth
Gas Furnace Repair in Duluth typically means diagnosing why the burners won’t light, why the blower won’t spin, or why the furnace locks out after sixty seconds. A failing igniter is the most common culprit on older units, followed by blower motors pulling high amps and gas valves that won’t open. On a 1990s Duluth home, a cracked igniter and a tired blower motor often fail together, because both components sit idle through Georgia’s humid summer and then get hit with the first hard cold snap in late fall.
Igniter and Flame Sensor Work
The igniter is the glowing element that lights your gas burner. When it cracks, the furnace won’t fire at all. A dirty or failing flame sensor will light the burners, then shut them down after a few seconds because the board thinks there’s no flame. Both jobs are common in Duluth and usually run $150 – $350 parts and labor.
Gas Valve and Board Diagnostics
If the igniter is fine but the furnace still won’t stay lit, the gas valve or control board becomes the suspect. We test the valve’s voltage and gas pressure before condemning it; a good valve doesn’t get replaced on a guess. Gas valve replacement in Duluth homes typically lands in the $300 – $700 range depending on the furnace model.
Furnace Tune Up in Duluth
Furnace Tune Up in Duluth is the best money you’ll spend before winter, because a $95 tune-up catches the $400 repair waiting to happen. We run a full sequence-of-operation check: burners, flame sensor, inducer motor, blower motor, capacitor, thermostat calibration, and gas pressure. The tune-up runs $80 – $200 depending on what we find and how much cleaning the unit needs.
What a Tune-Up Includes
We’ll clean the flame sensor, check the igniter resistance, inspect the heat exchanger for cracks, verify gas pressure, and measure the blower motor’s amp draw. You get a written report showing what was tested, what was found, and what we recommend, with no pressure to buy anything. Our techs aren’t paid on what they sell.
When Duluth Homes Need It Most
After a damp Duluth summer, furnaces that sat idle for six months get their first hard start on a cold November morning. That’s when igniters crack and capacitors swell. A tune-up in October catches those failures before the first freezing night, when every HVAC company in Gwinnett County is booked solid.
Trusted Brands We Service in Duluth
Our techs are factory-trained on nine major residential HVAC brands, including Trane, Lennox, Goodman, and Rheem, so we don’t have to figure out your unit on the fly. We stock common Duluth-market parts for those systems, igniters, flame sensors, capacitors, blower motors, meaning we can often finish the repair the same visit instead of ordering a part and coming back next week. A Trane furnace in a Duluth subdivision and a Goodman in an older home off Buford Highway get the same written guarantee.
Common Furnace Repair Problems We See in Duluth Homes
- Igniters cracking after a damp summer: Duluth’s humidity is brutal on igniter elements. When the furnace sits idle from April through October, corrosion builds, and the first cold snap snaps the igniter. That’s a $150 – $350 repair, not a replacement.
- Blower motors pulling high amps in 1990s builds: We see this constantly in Duluth’s older subdivisions. A blower motor straining against dirty ductwork or a clogged filter overheats, locks out, and takes the capacitor with it. We measure amp draw before replacing anything.
- High static pressure tripping the high-limit switch: Older Gwinnett County homes with undersized or kinked flex duct run static pressure too high. The furnace overheats, trips the limit, and cycles all day. The fix might be ductwork, not a new furnace, and a load calculation tells us which.
- Thermostat calibration drift masking a sizing problem: A furnace that short-cycles in a tight-build Duluth subdivision might not have a mechanical problem at all. If the system was sized by square footage instead of a Manual J load calculation, the thermostat ends up fighting the wrong-sized unit. We fix the real issue, not the symptom.

FAQs About Furnace Repair in Duluth
Usually a repair, not a replace. The most common cause is a cracked igniter or a dirty flame sensor, both of which are $150 – $350 fixes. We got a no-heat call from a homeowner off Buford Highway near downtown Duluth where the furnace would start, run about a minute, then lock out. Our tech found a failing blower motor pulling high amps and a cracked igniter, confirmed a healthy heat exchanger, and had the Carrier unit cycling again the same visit. Because the home was a 1990s build with marginal duct static pressure, we walked the homeowner through repair costs versus a SEER2 replacement using a real load calculation instead of a rule-of-thumb tonnage guess. Call (361) 306-9515 and we’ll give you the same straight answer for your furnace.
Because Duluth’s mix of newer tight-build subdivisions and older Gwinnett County homes means neighbors on the same street can have wildly different furnace sizing needs. A Manual J load calculation measures your home’s actual heat loss, square footage, window area, insulation, duct condition, and orientation. Guessing by square footage gets the tonnage wrong, and a wrong-sized furnace short-cycles, wastes gas, and dies early. We run the calculation before recommending repair or replacement, every time.
SEER2 is the updated 2023 efficiency rating for cooling, and for a furnace it applies to the AC side of your system. Better to focus on AFUE for the furnace: an 80% AFUE furnace sends 20 cents of every gas dollar up the flue, while a 95% AFUE unit keeps 95 cents of it heating your Duluth home. On a typical winter gas bill in this area, that difference is real money. We’ll show you the math for your specific house before you buy anything.
A furnace tune-up in Duluth runs $80 – $200 at Dalton Heating & Air.

No add-on charges when we’re already in the house. Call (361) 306-9515 to schedule before the next cold snap fills our calendar.
