Sunset Hills HVAC Companies like Weis understand how challenging it may be for some homeowners to manage HVAC repairs. Below you will find a maintenance checklist to provide you with a few go-to checks and tasks to keep your cooling, heating, and other systems functional:

  • Check thermostat settings to make sure your cooling and heating system maintains at a comfortable and reasonable level. Property owners can cut down costs by investing in automated thermostats to keep their homes cool in the summer and warm in the winter, and even kick on at specific times to lower energy consumption.
  • 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. Sunset Hills HVAC contractors like Weis point out that poorly-functioning equipment lowers a systems’ performance expectancy. Also check all of the system’s controls and oil/gas connections.
  • Lubricate all moving components. "Dry" parts cause friction and rust. This may result in increased workload and further reduces a system’s efficiency. You can always contact Weis Comfort Systems for more info about HVAC maintenance in Sunset Hills.
  • Inspect the condensate line. Your AC unit has to handle water. Ask an air conditioning contracting company about this process or look at these guidelines on American Home Shield.

It’s important to care for and monitor your HVAC systems.
