Prairie Du Rocher HVAC Companies like Weis Heating and Cooling understand how challenging it is for some homeowners to manage HVAC repairs. Here is our maintenance checklist to give you with a handful of go-to tasks and checks to keep your heating, cooling, and other systems functional:

  • Check thermostat to make sure your HVAC system maintains at a reasonable and comfortable level. You can cut down costs by investing in automated thermostats to keep their homes cool in the summer and warm in the winter, and even turn on at specific times to lower energy usage.
  • Tighten electrical connections. You can also measure voltages and currents of a system’s motors. Bad electrical connections may result in unsafe operation, poor efficiency, and even electrical fires. Prairie Du Rocher HVAC contractors like Weis Heating and Cooling note that poorly-functioning equipment lowers a systems’ performance expectancy. Also check all of the HVAC system’s controls and oil/gas connections.
  • Lubricate moving components. "Dry" parts lead to friction and rust. This usually results in increased workload and further reduces a system’s efficiency. Go ahead and call Weis Heating and Cooling for additional info about HVAC maintenance in Prairie Du Rocher.
