Maryland Heights HVAC Companies like Weis understand how difficult it is for some homeowners to manage HVAC repairs. Here is our maintenance checklist to provide you with a handful of go-to checks and tasks to keep your heating, cooling, and other systems functional:

  • Check your thermostat settings to ensure your cooling and heating system stays at a comfortable and reasonable level. Homeowners 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 specific times to lower energy usage.
  • Tighten all electrical connections. You can also measure currents and voltages of a system's motors. Bad electrical connections can cause electrical fires, poor efficiency, and unsafe operation. Maryland Heights HVAC contractors like Weis Comfort Systems note that poorly-functioning equipment lowers a systems' performance expectancy. Also check all of the system's oil/gas connections and controls.
  • Lubricate moving components. "Dry" parts lead to friction and rust. This may result in increased workload and further reduces a system's efficiency. You can always contact Weis Heating and Cooling for additional info about HVAC maintenance in Maryland Heights.
  • Inspect the condensate line. Your air conditioner unit has to handle water. Ask your air conditioning contracting company about this process or look at these guidelines on American Home Shield.
