You finally come home
from a rough, icy drive on a cold, bitter night. It was freezing, and
you’re looking to get comfy, so you reach out to turn up the dial
on your thermostat and find your furnace has ceased to hum and won’t
heat up. Your worst fear is unfolding in the midst of a freezing
night. However, don’t hit the panic button just yet. Before calling
for an emergency repair service, you may be able to check out and
troubleshoot a few things yourself.
Check the basics—power
supply, temperature, and gas supply (if unit is gas-powered). Check
the main breaker to confirm if the power is on, then make sure the
power in the equipment is turned on, as well. Afterwards, go to the
wall thermostat and double-check the settings. If it’s set to heat,
then it should be pumping out heat. If the furnace is blowing cold
air, make sure the fan is set to auto, and not on. For gas-powered
units, check if the meter is on, and verify that the tank is not
empty.
If the furnace powers
on but some rooms aren’t receiving heat, then the problem must be
in the air ducts themselves. Check the filters within the ducts for
clogs like dirt and grime, as these restrict air flow and overwork
the machine. Clean them and put them back on.
If the abovementioned
fixes do not work at all, then it is time to call for a 24/7
emergency furnace repair service.
