Experts in heating and cooling from Indianapolis brace for the cold

When a thermostat is defective, the entire HVAC system may not function altogether. To test if it is working, take temperature readings using a separate thermometer. If the difference in temperature is more than a few degrees, it may need a new battery or it may need to be replaced. Fueling the fire Different furnaces have different fuel sources. Make sure the fuel delivery switch of your furnace is set to the “on” position. If the pilot doesn’t ignite, this means no fuel is being supplied and there’s nothing to warm the circulating air. If you notice anything else that seems amiss in your HVAC system, consult an expert in heating and cooling from Whiteland like Bri-TechHVAC to get your furnace up and running in time for the arrival of winter.
