Oakville HVAC Companies like Weis know how difficult it may be for some homeowners to handle HVAC repairs. Here is our maintenance checklist to give you with a few go-to checks and tasks to keep your heating, cooling, and other systems functional:

  • Check thermostat settings to make sure the HVAC system maintains at a reasonable and comfortable level. Property owners can reduce power bills by investing in digital thermostats to keep their homes warm in the winter and cool in the summer, and even kick on at set times to lower energy consumption.
  • Check electrical connections. You should also measure currents and voltages of a system's motors. Bad electrical connections may result in electrical fires, poor efficiency, and unsafe operation. Oakville HVAC companies like Weis Comfort Systems point out that poorly-functioning equipment reduces a systems' performance expectancy. Also check all of the system's controls and oil/gas connections.
  • Lubricate all moving parts. "Dry" parts cause friction and rust. This may result in increased workload and further decreases a system's efficiency. Call Weis for more info about HVAC maintenance in Oakville.
  • Inspect the condensate line. Your AC unit handles water. Ask your air conditioning contracting company about this step or view these guidelines on American Home Shield.

It's important to monitor and care for your heating and cooling systems. Weis, one of the leading HVAC companies in Oakville, is here to help clients maintain these systems to improve efficiency, reduce costs, and increase longevity.
