Des Peres HVAC Companies like Weis understand how challenging it may be for some homeowners to handle HVAC repairs. Here is our maintenance checklist to provide you with a handful of go-to tasks and checks to keep your heating, cooling, and other systems functional:

  • Check thermostat settings to ensure your HVAC system stays at a reasonable and comfortable level. Property owners can save money 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 consumption.
  • Check all electrical connections. You should also measure currents and voltages of a system’s motors. Faulty electrical connections are known to cause electrical fires, poor efficiency, and unsafe operation. Des Peres HVAC contractors like Weis Comfort Systems note that poorly-functioning equipment lowers a systems’ life 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 a system’s efficiency. You can always contact Weis Heating and Cooling for additional info about HVAC maintenance in Des Peres.
  • Check the condensate line. Your AC unit needs to manage water. Ask an AC contracting company about this process or view these guidelines on American Home Shield.

It’s important to monitor and care for your heating and cooling systems. Weis, one of the leading HVAC companies in Des Peres, is here to help clients maintain HVAC systems to improve efficiency, reduce costs, and increase longevity.
