Fresno Heater Repair Tips
Before you decide to do any furnace repair understand this:
While gas furnaces and heaters have shut off valves and control shut offs, they are not guaranteed to be fail safe. If you are working on your furnace and smell gas immediately call the gas company or fire department and report a Gas Leak. Exit your home and do not reenter until a qualified professional has inspected your house.
DO NOT SWITCH ON OR OFF LIGHT SWITCHES OR SHUT OFF THE GAS LEADING TO THE FURNACE. JUST GET OUT AND CALL A PROFESSIONAL.
