We have several different quality and maintenance check points in our furnace plans, take a look!

All Furnace Maintenance includes:

  • Check thermostat settings to ensure the cooling and heating system keeps you comfortable when you are home and saves energy while you are away.
  • Tighten all electrical connections and measure voltage and current on motors. Faulty electrical connections can cause unsafe operation of your system and reduce the life of major components.
  • Lubricate all moving parts. Parts that lack lubrication cause friction in motors and increases the amount of electricity you use.
  • Check and inspect the condensate drain in your central air conditioner, furnace and/or heat pump (when in cooling mode). A plugged drain can cause water damage in the house and affect indoor humidity levels.
  • Check controls of the system to ensure proper and safe operation. Check the starting cycle of the equipment to assure the system starts, operates, and shuts off properly.
  • Check all gas (or oil) connections. This includes checking the gas pressure, burner combustion, and heat exchanger.
Improperly operating gas (or oil) connections are a fire hazard and can lead to health issues. When a burner gets dirty or a heat exchanger is cracked it can causes improper burner operation. Either can cause the equipment to operate less safely and efficiently.
