Furnace 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 light 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. Schedule furnace repair.
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 emergency heating repair across Duluth. Call (678) 853-7440 and we'll bring the warmth back.
How often should I service or tune up my furnace?
At least once a year, ideally in fall before heating season. An annual tune-up keeps your furnace efficient and safe, lowers bills, prevents breakdowns, checks for carbon monoxide, and helps keep your warranty valid. Club Zen members get annual inspections and priority scheduling.
How often should I change my furnace filter?
Every one to three months during heating season, depending on usage, pets, and dust. A clean filter improves airflow, efficiency, and indoor air quality, and protects the blower and heat exchanger — one of the easiest ways to prevent breakdowns.
What are the signs my furnace is failing?
Weak or cold airflow, uneven heating, rising energy bills, banging or squealing noises, a yellow burner flame, strange smells, short cycling, and frequent repairs on a furnace over 15 years old. Notice any of these? Schedule a diagnostic before it becomes a bigger issue.
Should I repair or replace my furnace?
As a rule of thumb, 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 an honest recommendation for both.
How much does furnace repair or installation cost?
It depends on your system, its size and efficiency, and the condition it's in — so we don't guess. We give you a clear, written quote up front before any work begins, and our free Instant Quote prices a new system online in minutes. Financing is available.
What furnace brands do you install and service?
All major brands — including Lennox, Trane, Carrier, Daikin, American Standard, Bryant, Goodman, and Amana. As a Lennox Premier Dealer, we'll help you choose the right, efficient gas or electric furnace or heat pump for your home.
