Pevely HVAC Companies like Weis Comfort Systems know how difficult it may be for some homeowners to handle HVAC repairs. Below you will find a maintenance checklist to give you with a few go-to checks and tasks to keep your cooling, heating, and other systems functional:

  • Check thermostat settings to make sure the cooling and heating system maintains at a reasonable and comfortable level. You can save money by investing in automated 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 voltages and currents of a system’s motors. Faulty electrical connections can cause unsafe operation, poor efficiency, and even electrical fires. Pevely HVAC contractors like Weis Comfort Systems note that poorly-functioning equipment lowers a systems’ life 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 reduces your system’s efficiency. You can always contact Weis Comfort Systems for more info about HVAC maintenance in Pevely.
  • Inspect the condensate line. Your AC unit handles water. Ask your AC contracting company about this step or view these guidelines on American Home Shield.
