Furnace and heat pump tune-up
A heating tune-up cleans the burners and flame sensor, tests the igniter and every safety switch, checks gas pressure and venting, and measures CO. For heat pumps, it tests defrost and backup heat. Book it in September or October.
- Same-day appointments when available
- Licensed HVAC contractors
- Written price before any repair

In cold climates a furnace may run thousands of hours each winter, so annual service matters for safety and reliability.
In mild climates, the first cold night of the year is when many furnaces fail after sitting unused for months.
