This can be Caused by your Thermostat:

  • Set 3 degrees below room temperature

What best describes your heating problem?

Make sure power is getting to the furnace

Try this:

  • Check your home’s electrical panel. Flip the furnace’s circuit to “off” and then “on” again.
  • Look for a switch (like a light switch) near your furnace and make sure it is set to "on".

  • Try flipping that circuit to “off” and then “on”.

Note: If your heat pump is regularly tripping your circuit breaker, contact us immediately as there is a larger problem.

What type of smell?
Did you just turn your heater on for the first time this winter?

This is likely normal.

The smell should go away in a few minutes.

Contact us if the smell persists.

Turn off your furnace now!

There could be a dangerous gas leak in your home. Turn off your furnace immediately and contact a heating repair person.

This is usually caused by a dirty coil and/or lack of regular maintenance on your heater.
