Furnace Tips by Treat’s Heating & Cooling
Warming up your home is quite simple when all you have to do is click a button. The thermostat senses the house temperature and then activates internal contacts that close the electrical circuit. Closing the circuit signals the furnace to start and the ignition starts. Older furnaces may use a standing pilot light while some newer furnaces use an electronic ignition.
Gas then flows to the main burners to heat the furnace up. Once it reaches the correct temperature, the furnace blower fan comes on forcing air through the heating ducts and out of the hot air vents also known as registers. The thermostat responds to the warmer temperature by opening the contacts, breaking the circuit. The fan continues to run for a brief period of time perhaps two to three minutes to dissipate the heat remaining inside the furnace chamber. Once the fan stops, the warm air continues to blow and then the thermostat waits for the temperature to drop again.
If you find yourself waking up to a furnace that is not turning on, there could be several reasons why this is happening. First, you want to check the thermostat to be sure that it is set into “heat” mode. When you turn the thermostat up you should hear a click. Digital thermostats will usually display a flashing code when something is wrong.
If all of these things don’t result in your furnace turning on, you can call Treat’s Heating & Cooling for service 360.825.0800
