West County HVAC Companies like Weis Comfort Systems understand how challenging it is for some homeowners to manage HVAC repairs. Here is our maintenance checklist to provide you with a handful of go-to tasks and checks to keep your cooling, heating, and other systems working:

  • Check thermostat to make sure the HVAC system maintains at a comfortable and reasonable level. You can reduce power bills by investing in digital thermostats to keep their homes cool in the summer and warm in the winter, and even kick on at set times to lower energy consumption.
  • Tighten all electrical connections. You should also measure currents and voltages of a system’s motors. Faulty electrical connections may cause electrical fires, poor efficiency, and unsafe operation. West County HVAC contractors like Weis point out that poorly-functioning equipment lowers a systems’ life expectancy. Also check all of the HVAC system’s oil/gas connections and controls.
  • Lubricate all moving components. "Dry" parts lead to friction and rust. This usually results in increased workload and further decreases a system’s efficiency. You can always contact Weis for more info about HVAC maintenance in West County.
  • Inspect the condensate line. Your air conditioner unit needs to manage water. Ask an air conditioning contracting company about this step or look at these guidelines on American Home Shield.
