What to expect

Gas and electric furnace repair covers ignitor failures, flame sensor cleaning, blower motor, gas valves, heat exchanger inspection, and control board issues. Annual maintenance ($120-$200) prevents most no-heat calls. Carbon monoxide testing should be part of every furnace service visit.

Cold winters: 5,500-7,000 HDD. Heating oil still common in older homes; conversions to gas, heat pump, and dual-fuel increasingly common.

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.
