Why is My Heater Failing?

In most cases, complaints with the heating system are easily and quickly solved. Here are a few common reasons why your heater is blowing cold air:

  • Thermostat setting

    – Make sure the thermostat is set to “heat” and in the “auto” position. Switched to “on,” the fan will blow even when the unit is off. You want the furnace to start up at the same time as the fan.

  • Furnace needs to heat up

    – Once the heating system is turned on, a lot of moving parts need to fire up. Be patient, especially the first time the furnace runs for the season. You should feel warm air within 15 minutes.

  • Clogged air filter

    – A dirty air filter blocks airflow and can lead to the system overheating and tripping a high limit switch or shutdown as a safety measure. Replace dirty filters regularly.

  • No pilot light

    – Older models feature a small blue flame or pilot light that’s used to heat up the system. Contacting the professionals from Green Valley Cooling & Heating is the smart decision.

  • Overheated system

    – Safety features shut the system off to prevent a carbon monoxide leak and fire. Overheating can be due to clogged air filters, mechanical failure or even the system reaching the end of its service life.

  • Ductwork leaks

    – Holes and gaps in the ductwork not only allow heated air to escape but pull cold air into the home. You’ll want to get in touch with Green Valley Cooling & Heating to identify and seal leaks.

  • Thermostat issues

    – There might be a wiring issue with the thermostat or a model that is not compatible with your particular heating system.
