Common Furnace Problems We Repair

Nothing kicks on when heat is called for — commonly a pilot/ignition, limit switch, breaker, or control-board problem.
Book This RepairShort Cycling
Turning on and off too often wears the system out and wastes energy — usually airflow, thermostat, or overheating.

Banging, rattling, squealing, or scraping usually points to a loose part, worn blower, or ignition issue worth fixing early.

Some rooms stay cold or airflow feels weak — often a dirty filter, blower, or duct issue restricting your heat.

Furnace Repair Questions, Answered
Why is my furnace blowing cold air or not heating?
Common causes: a clogged filter, a thermostat set or wired wrong, a pilot or ignition problem, a tripped limit switch, a faulty flame sensor, or a gas-supply issue. Our techs run a full diagnostic to find the real cause and get your heat back on — safely.
Do you offer same-day or emergency furnace repair?
Yes. When your furnace quits on a cold Georgia night, you shouldn't have to wait. We offer fast, same-day and 24/7 emergency heating repair across Duluth. Call (678) 853-7440 and we'll bring the warmth back.
Is it safe to keep running a furnace that needs repair?
If you smell gas, see a yellow burner flame, hear loud banging, or suspect carbon monoxide, turn the system off and call us right away — these can be hazards. For milder issues like weak airflow, schedule a prompt diagnostic before a small problem grows.
What are the most common furnace problems?
No heat or cold air, a furnace that won't start, short cycling, weak airflow, banging or squealing noises, a yellow burner flame, and thermostat problems. We diagnose the root cause rather than just treating the symptom.
Should I repair or replace my furnace?
Repair if your furnace is under about 12–15 years old and the fix is minor; consider replacing if it's older, needs frequent repairs, has a cracked heat exchanger, or can't keep you comfortable. We'll give you an honest recommendation either way.
How much does furnace repair cost?
It depends on the problem, the parts involved, and your system — so we don't guess. We diagnose the issue and give you a clear, written quote up front before any work begins, with no surprise charges. Financing is available for larger repairs.
What furnace brands do you repair?
All major brands — including Lennox, Trane, Carrier, Daikin, American Standard, Bryant, Goodman, and Amana — across gas, electric, and heat pump systems. As a Lennox Premier Dealer, we know these systems inside and out.
How can I prevent furnace breakdowns?
Change your filter every one to three months, keep vents clear, and schedule an annual tune-up before heating season. Regular maintenance catches small issues early — Club Zen members get annual inspections and priority scheduling.
