Webster Groves HVAC Companies like Weis understand how difficult it may be 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 working:

  • Check thermostat to make sure the HVAC system maintains at a reasonable and comfortable level. Homeowners can cut down costs by investing in digital thermostats to keep their homes warm in the winter and cool in the summer, and even turn on at set times to lower energy consumption.
  • Tighten electrical connections. You can also measure currents and voltages of a system’s motors. Bad electrical connections may cause unsafe operation, poor efficiency, and even electrical fires. Webster Groves HVAC companies like Weis Comfort Systems point out 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 your system’s efficiency. Call Weis Heating and Cooling for additional info about HVAC maintenance in Webster Groves.
