Smithton HVAC Companies like Weis Comfort Systems 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 tasks and checks to keep your cooling, heating, and other systems functional:

  • Check thermostat to ensure your HVAC system stays at a comfortable and reasonable level. Homeowners can cut down costs by investing in digital thermostats to keep their homes cool in the summer and warm in the winter, and even turn on at specific times to lower energy consumption.
  • Tighten electrical connections. You should also measure voltages and currents of a system’s motors. Bad electrical connections are known to cause unsafe operation, poor efficiency, and even electrical fires. Smithton HVAC companies like Weis note that poorly-functioning equipment reduces a systems’ performance expectancy. Also check all of the system’s controls and oil/gas connections.
  • Lubricate all moving parts. "Dry" parts cause friction and rust. This usually results in increased workload and further reduces a system’s efficiency. You can always contact Weis for more information about HVAC maintenance in Smithton.
  • Inspect the condensate line. Your AC unit handles water. Ask your AC contracting company about this step or view these tips on American Home Shield.
