Furnace repair. Tested flame sensor, pressure switches, hsi, fan motor amperage and capacitor, inducer motor amperage, and gas valve voltage. Found furnace locked on flame sensor, cleaned sensor, furnace ignites and is working. Reset to factory specs for safe, efficient operation. Let customer know about our annul VIP maintenance agreement. And he would get 2 check ups a year one on ac unit and one on furnace. He will call in the spring to sign up for plan.
