If your furnace struggled last winter. ran constantly, heated unevenly, or your gas bill was higher than your neighbors. a tune-up addresses those issues. Systems that haven’t been tuned up in over a year are at higher risk for mid-winter failures when temperatures drop below freezing and every HVAC tech in Prince George’s County is booked. ## Our Furnace Tune-Up Process We clean the burner assembly, check the ignitor, test the flame sensor, inspect the heat exchanger, verify gas pressure, test safety controls, check the blower motor and fan, replace or clean the air filter, and calibrate your thermostat. We run the system through a complete cycle to verify proper operation. The whole visit takes 45 minutes to an hour. ## Furnace Tune-Up Cost in Bowie Tune-up pricing is straightforward and quoted upfront. Cost depends on your furnace type. gas, electric, or propane.
