My house went from 75 degrees to 69 and my
furnace is not coming on. What can I do?
Reasons Your Furnace May Not Turn On
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
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
to see if you can restore the power. Some homes
have a switch in the mechanical room with the furnace. Check the switch
as well. Many times we find the switch has been accidentally switched to
the off position. In our home it looks just like a light switch and the
kids have turned it off in error.
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.
Check and change the air
If you haven’t kept up
with the furnace’s preventive maintenance, now’s the time to contact your
trusted HVAC professional at Airomatic Heating and Air Conditioning. Dirty
filters, clogged blowers, closed or blocked registers will all affect the
furnace’s performance and an expert can service this issues.
