Valley Park HVAC Companies like Weis Heating and Cooling know how difficult it is for some homeowners to handle HVAC repairs. Below you will find a maintenance checklist to provide you with a few go-to tasks and checks to keep your cooling, heating, and other systems working:

  • Check thermostat to make sure your HVAC system maintains at a reasonable and comfortable level. Property owners can cut down costs 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 usage.
  • Check all electrical connections. You can also measure currents and voltages of a system’s motors. Bad electrical connections are known to result in unsafe operation, poor efficiency, and even electrical fires. Valley Park HVAC companies like Weis Comfort Systems note that poorly-functioning equipment reduces a systems’ performance expectancy. Also check all of the system’s oil/gas connections and controls.
  • Lubricate all moving components. "Dry" parts lead to friction and rust. This may result in increased workload and further decreases a system’s efficiency. Go ahead and call Weis for additional information about HVAC maintenance in Valley Park.
  • Inspect the condensate line. Your AC unit needs to manage water. Ask your AC contracting company about this process or view these tips on American Home Shield.
