TROUBLESHOOTING TIPS BEFORE YOU CALL

Furnaces —Man Fixing Broken Furnace in Centennial, CO
  • Check to see if your filter is clean. If not, this may be a possible symptom for your service needs today.
  • Newer furnaces are equipped with an LED light, which flashes to tell you the diagnostic issue. This light is located on the computer board where the blower compartment is. In most cases, you should not have to remove the doors to see this indicator light. It should be a clear porthole plastic viewing window the size of a half-dollar. After viewing the LED indication, remove the door and look at the back of the door for a list of diagnostic codes, or refer to the paperwork for the furnace. Having this information available when you call us is extremely helpful.
  • If your furnace is not working, check your doorbell. The doorbell is powered by the furnace breaker, so if the doorbell doesn’t work, check your breaker at the main panel. If this breaker continues to break, call us because this might be a symptom of a larger problem.
