Are you Sure You Need Furnace Repair?

Several times during each cold snap, our service tech arrives on a heat call only to find that the problem was a simple one that could have been resolved by the owner. Typical simple issues include:

  • Thermostat improperly set: Make sure your thermostat is "ON", is set to "HEAT", and the desired room temperature is set higher than the current ambient temperature.
  • No power to the heating system: Check you circuit breaker panel to ensure that your heating system breaker is "ON".
  • Emergency furnace switch off: Make sure your "FURNACE SWITCH" is set to "ON". This switch is typically a traditional toggle switch that may have a RED cover-plate.
  • Dirty filters: Change your furnace filter and restart your furnace.

After checking these items, if your Furnace System is still not running properly call us day or night and we'll dispatch a service tech to help!

Check These 5 Things Before You Call

On a significant percentage of our heat pump repair calls, it turns out the problem was simple and could have been corrected easily by our customer. Check these items before you call:

  • 1. Make sure your thermostat is "ON", is set to "HEAT" in winter or "COOL" in Summer and the desired room temperature is set properly to initiate heat pump operation.
  • 2. Make sure your "SYSTEM SWITCH" is set to "ON". This switch is typically a traditional toggle switch that may have a RED cover-plate.
  • 3. Check you circuit breaker panel to ensure that your heat pump system breaker is "ON".
  • 4. If your heat pump power was off, or if the thermostat was not set properly, after correcting the issue give it a few minutes: many systems have a time delay on start-up that can delay operation.
  • 5. Change your air handler filter and re-start your system.
