Ladue HVAC Companies like Weis Comfort Systems know how difficult it is for some homeowners to manage HVAC repairs. Below you will find a maintenance checklist to give you with a few go-to tasks and checks to keep your heating, cooling, and other systems working:

  • Check thermostat settings to ensure your cooling and heating system stays at a reasonable and comfortable level. Homeowners can cut down costs by investing in automated thermostats to keep their homes warm in the winter and cool in the summer, and even kick on at set times to lower energy consumption.
  • Tighten all electrical connections. You should also measure voltages and currents of a system’s motors.

  • Lubricate all moving components. "Dry" parts lead to friction and rust. This may result in increased workload and further decreases a system’s efficiency. You can always contact Weis for more information about HVAC maintenance in Ladue.
