Fairview Heights HVAC Companies like Weis know how challenging it may be for some homeowners to handle 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 working:

  • Check your thermostat settings to make sure the HVAC system stays at a comfortable and reasonable level. Homeowners can cut down costs by investing in automated thermostats to keep their homes cool in the summer and warm in the winter, and even kick on at set 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. Fairview Heights HVAC contractors like Weis Comfort Systems point out that poorly-functioning equipment reduces a systems’ life 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 may result in increased workload and further reduces your system’s efficiency. You can always contact Weis for additional information about HVAC maintenance in Fairview Heights.
  • Inspect the condensate line. Your AC unit has to handle water. Ask an AC contracting company about this process or look at these guidelines on American Home Shield.

It’s important to care for and monitor your HVAC systems. Weis Heating and Cooling, one of the top HVAC companies in Fairview Heights, is here to help clients maintain these systems to reduce costs, improve efficiency, and extend their longevity.
