Frequently asked questions
How often should a furnace be serviced?
Annually, before heating season. Service includes ignitor inspection, flame sensor cleaning, gas pressure check, blower service, and carbon monoxide testing. Plan to pay $120-$200.
How long should a furnace last?
15-20 years for gas, 20-30 years for electric. Replace before failure if you're at 15+ years and have had two repairs in two seasons — efficiency gains alone often justify replacement.
What is AFUE and what should I look for?
AFUE measures how much fuel becomes usable heat. Code minimum is typically 80% in warm climates and 90%+ in cold. High-efficiency 95-98% AFUE furnaces pay back in 5-10 years in cold climates.
