Why is My Heater Blowing Cold Air?!

Why is my heater blowing cold air?!

Its the middle of a blistering cold winter and
your heating system decided to stop doing its
job.  Why couldnt it have been on a nicer day?
You know the old saying about Murphys Law
Anything that can go wrong, will go wrong. During
extra cold days, your heating system has to work
extra hard to keep your home at comfortable
temperature. This extra work can cause the system
to break down over time. Before calling your
local service technician, try these tips to
restore heat to your home.

Check the thermostat

• Is the system selector switch in the heat
  position?
• Make sure the temperature is set at least 3
  degrees above current room temperature.
• If your thermostat is electronic, are the
  batteries charged? Is the display showing?

Forced Air Furnaces Only. If your thermostat has
a switch to control the furnace fan, switch the
fan ON. (This switch will usually be located at
the bottom of the thermostat, closer to the left
side and will be marked ON and AUTO.) Listen
to hear the furnace fan coming on. If you cannot
hear the fan, go to one of the supply registers
and see if you can feel any air coming up. If the
fan is not running, there may be no power to the
furnace. If the thermostat is set properly, next
step is to check to see that there is power to
the furnace

Check shutoff switches and breakers

• It sounds unbelievable, but furnace technicians
  often find that the only repair a furnace needs
  is to be turned on. The switch for most furnaces
  looks just like a light switch and is usually
  located very close to the furnace Make sure the
  switch is turned on. Also be sure to check the
  circuit breaker or fuse for the furnace as well.

Change the filter

• We have found that a majority of heat related
  issues are solved or avoids just by making sure
  you keep the filters changed on a regular basis.
  If you have the owners manual for the furnace,
  check to learn where the filters are located on
  your furnace.

7
Make sure the gas is on

• Just as with switches, someone may have turned
  off a gas valve and then forgotten to turn it
  back on. Trace the gas line back from the furnace
  to the meter, and if you see a handle thats
  perpendicular to the gas pipe, turn it so its
  parallel. If you have an old furnace or boiler,
  you may have a pilot light. Remove the front
  panel and the burner cover and check to make sure
  its lit.

Clean away leaves and debris from heat pumps or
intake and exhaust vents.

• If you have a furnace that vents out the side of
  the house, make sure nothing is blocking the
  intake or exhaust. If either of the pipes is
  covered with screen mesh (like window screen),
  replace it. If ice is clogging one of the pipes,
  you have a bigger problem somewhere in the
  system. Before heating season starts, hose it
  down gently from the top to rinse dirt and debris
  out of the housing.
