Furnace Maintenance Plans in Oakville, MO, Include:

  • Thermostat Settings Check to make sure that your home's furnace keeps you comfortable in the fall and winter while you are relaxing at home, and saves energy while doing so.
  • Tightening of Electrical Connections and measuring voltage and current on motors. Defective electrical connections can lead to dangerous operation of your furnace and reduce the life of critical 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 central air conditioner, heating system, and/or heat pump (when in cooling mode). A plugged furnace drain can cause water damage in homes and affect indoor humidity levels.
  • Check Controls of the Furnace to guarantee efficient and non-hazardous operation. This includes testing the starting cycle of the furnace to make sure that the system turns on, works correctly, and shuts off properly.
  • Check All Gas (or oil) Connections. Our furnace maintenance services in Oakville involve checking the gas pressure, burner combustion, and heat exchanger on your furnace to ensure that your furnace is in optimal shape.

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