Check These Things Before You Call Us:

  • You should make sure that your thermostat is in "On" mode, set to "heat" and the desired room temperature is set higher than the current ambient temperature.
  • Assure that your circuit breaker is "ON" for your heating system.
  • Ensure that your "SYSTEM SWITCH" is set to "ON". This switch typically is a toggled dial-plate that may have a RED casing.
  • When your Furnace thermostat was out of commission or the system power was shut down, after turning the system back on give it a few minutes; many AC systems have a time-delay function on startup.
  • If your system is blowing warm air, but not heating as well as it should, check your furnace filter, clean and replace it and restart the system.
