If you need to know exactly is involved in our Furnace Maintenance? We have several personalized maintenance plans that Concord residents can pick from and this is because our technicians realize that no two Concord homes are the similar in heating needs. 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.
Malfunctioning gas (or oil) connections are a fire hazard and can cause health complications. When a burner gets dirty or a heat exchanger is cracked it can causes improper burner operation. Either can cause the equipment to perform less safely and efficiently.
