What Affects Your Cost
Fuel type
Gas furnace repairs are usually less expensive than electric resistance or heat pump auxiliary heat issues.
AFUE rating
High-efficiency 90%+ furnaces use more parts (condensate, inducer, pressure switches) and cost more to repair.
System age
Furnaces 15+ years old hit the point where parts are harder to source and replacement makes more sense.
Carbon monoxide concerns
Any heat exchanger crack is a no-compromise safety issue — we never patch them.
How to Save Money
- Schedule a fall tune-up before October to catch igniter and flame sensor wear before peak season.
- Replace your furnace filter monthly during heating season to protect the blower motor.
- If your furnace short cycles, call us early — it's usually a sensor or pressure switch, not the whole unit.
- Install a CO detector near sleeping areas on every floor — a $30 investment that saves lives.
Frequently Asked Questions
How long should a furnace last?
Most gas furnaces in Central Kentucky last 15-20 years with annual maintenance. Heat pumps typically 12-15 years.
Is it worth repairing a 15-year-old furnace?
Sometimes. If the repair is under $500 and the unit has been reliable, repair it. For major repairs over $1,000, replacement usually pays for itself in 5-7 years.
