This isn’t a scenario you want to encounter on a chilly Colorado day: you don’t year the familiar noise you expect from your furnace as it kicks in to combat the cold. Instead, it sits silent and no warm air comes from your vents. Obviously, something is wrong—but what?
There are a number of reasons that your furnace might refuse to turn on. Some you can resolve yourself quickly. Others will need the assistance of repair technicians to analyze and remedy. You’ll want this issue dealt with as soon as possible, so make sure you keep contact information handy for an experienced HVAC contractor like Bell Plumbing and Heating.
We have more than eighty years of service to our credit: we’ll get your furnace running again with the proper heating repair service in Denver, CO it needs.
Thermostat error/malfunction: One of the first things to do when your furnace won’t turn on is to see that the thermostat is set correctly. An error with a programmable or digital thermostat could mean the furnace doesn’t think the house is cold enough to require it to provide heat. The thermostat could also have faults so it is sensing the indoor temperature incorrectly. This latter problem will need professional repairs.
Tripped circuit breakers: This is an issue not only for electrical furnaces but also for many gas-powered furnaces that use an electric igniter. A power surge along the line could trip one of the circuit breakers without you realizing it. Check the electrical panel to see if you can restore the power.
Failed pilot light/ignition: The pilot light can go out on a gas or oil furnace, which means the burners will not be able to ignite. If you can’t relight the pilot light on your own, you will need an HVAC technician to examine the burner unit and discover if there is a gas flow problem or excessive dirt along the burner. For electric-powered furnaces, ignition failure will prevent any of the heating elements from activating.
There is also the unfortunate reality that eventually a furnace will become too worn and suffer a complete shutdown. This may require installing a replacement system. However, you can help make sure your furnace lasts for many years with regular preventive maintenance; it only requires an annual visit from a technician to keep your furnace in its best running condition.
