  • Thermostat Settings Check to make sure that your home’s furnace keeps you comfortable during the harshest fall/winter conditions, and saves energy while doing so.
  • Tightening of Electrical Connections and measuring voltage and current on your furance’s motor. Faulty electrical connections can result in hazardous operation of your heating system and decrease the life of essential components in your furnace.
  • Lubrication. Non-maintained furnace parts can lead to resistance in motors and increase the level of electricity you use, which can cause wear-and-tear on your system and higher energy use.
  • Check and Inspect the Condensation Drain in your home’s A.C., heating system, and/or heat pump (when in cooling mode). A clogged furnace drain can cause water damage in homes and affect indoor humidity levels.
  • Check Controls of the Furnace to ensure safe operation. This includes testing the starting cycle of the furnace to make sure that it starts, operates, and shuts off properly.
  • Check All Gas (or oil) Connections. Our furnace maintenance services in Dupo involve testing the gas pressure, burner combustion, and heat exchanger on your furnace to ensure that your furnace is in optimal shape.

Defective furnace connections are dangerous and can lead to health issues. If you have a dirty burner or cracked heat exchanger in your furnace, this can result in improper burner operation that can make your furnace operate less safely and efficiently.
