Gas/Electric Furnace Repair and Maintenance in Waterloo

We have an impressive selection of furnaces that we offer to Waterloo residents, which means that we can perform repairs and services on a large selection of furnaces. We offer repair services on furnace brands such as Daikin®, Lennox®, WaterFurnace® and many more!

You might be wondering what exactly is offered in our Furnace Maintenance? We have several custom maintenance plans that Waterloo residents can pick from and this is due to the fact that our specialists understand that no two Waterloo homes are the same in heating demands. 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.
Poorly operating gas (or oil) connections are a fire hazard and can contribute to health complications. A cracked heat exchanger or dirty burner causes improper burner operation. Either can cause the equipment to function less safely and efficiently.
