What to do When Your Furnace Won't Ignite Published on February 23, 2017 We are getting through the last few weeks of winter but we still have to have our furnaces, especially during cold nights. Nothing is worse than laying down at night just to find out your furnace won’t start up. If you find yourself in this situation, here are a few things you can check yourself before your call Mountainwest Service Experts Heating & Air Conditioning. Check Air Filters You should change standard air filters each month. If you do not, they can become clogged, obstructing air flow and resulting in your furnace malfunctioning. Check Your Thermostat Start by turning the thermostat up a few degrees to get the furnace to turn on. If the actual room temperature is higher than the thermostat, the furnace won’t run. Also, make sure the system switch is on “heat” or “auto.” Check the Power It may seem silly, but confirm the power switch next to the heating equipment is “On.” Even gas heating systems use electricity so make sure the breaker has not tripped and that the power switch wasn’t accidently flipped to the “Off” position. If you review all these things and your heating equipment will still not kick on, give Mountainwest Service Experts Heating & Air Conditioning a call at 385-399-0280 and we’ll come out and get you heating again as soon as possible.
