Chicken Soup for Your Furnace

Sometimes if your furnace seems a bit out of sorts, a home remedy is all that is required. If you check these things before you call the Doc, you may have your heating system running perfectly in no time:

  • Low Energy Levels: If your heating system doesn't have power it can't run. Make sure your "FURNACE SWITCH" is set to "ON". This switch is typically a toggle switch with a RED cover-plate adjacent to the entrance to your utility space. Also, check your circuit breaker panel to ensure that your heating system breaker hasn't tripped. Some furnace utility spaces have a replaceable thermal fuse on the ceiling near the furnace. Make sure that fuse is in place.
  • Proper Pressure: Without proper gas pressure your furnace can't run properly. Make sure the manual shutoff valve on the gas line to your furnace is turned "ON". If possible, verify with another gas appliance like your oven or range that your home has natural gas available.
  • Got the Chills: Your thermostat measures the temperature and tells the furnace when to run. Make sure your thermostat is "ON", is set to "HEAT", and the desired room temperature is set higher than the current ambient temperature. If your thermostat is equipped with a battery, change it now.
  • Your Furnace Needs to Breath: Proper airflow is critical to proper operation. If your furnace has a disposable filter, change it now. Verify that almost all of your systems supply registers and cold air returns are open and free of obstruction.

Emergency Furnace Service

If you call us, we'll dispatch a professional heating tech day or night. When you need the skills of a professional, we offer emergency heating repairs for both residential and commercial applications around the clock.

Our top-rated, licensed and insured heating techs offer gas furnace service regardless of the brand. Common furnace service issues include:

  • Furnace is not working at all. It appears to have power and gas, but nothing at all happens on a call for heat:
    A blocked vent system, condensate line, or lack of power.
    A failed component like a transformer, furnace control, or inducer motor.
  • Furnace tries to start, but either fails to fire, or fire drops out shortly after lighting:
    An obstructed vent system.
    Improper grounding or incorrect gas pressure.
    Problem with the burner trays.
  • Furnace runs ok, but sometimes fails to light, or shuts off prematurely and fails to restart.
    Problem with the thermostat or T-stat batteries.
    Problem with the flame safety components.
  • Furnace runs, but something seems to have changed:
    Dirty filters and lack of maintenance. This would cause inconsistent temperature or wide temperature swings, unusual blower noise, or rapid furnace cycling.

If we find your furnace needs major repairs, or if it's more than 12 years old, we'll likely recommend you consider upgrading to a new Armstrong or Ducane furnace.
