Robertsville HVAC Companies like Weis Comfort Systems know 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 heating, cooling, and other systems functional:

  • Check thermostat to ensure your cooling and heating system maintains at a reasonable and comfortable level. You can cut down costs by investing in digital 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.
  • Tighten all electrical connections. You should also measure voltages and currents of a system’s motors. Bad electrical connections can result in unsafe operation, poor efficiency, and even electrical fires. Robertsville HVAC companies like Weis Heating and Cooling point out that poorly-functioning equipment lowers a systems’ life expectancy. Also check all of the HVAC system’s controls and oil/gas connections.
  • Lubricate moving parts. "Dry" parts cause friction and rust. This may result in increased workload and further reduces your system’s efficiency. You can always contact Weis Comfort Systems for additional info about HVAC maintenance in Robertsville.
  • Inspect the condensate line. Your AC unit needs to manage water. Ask an air conditioning contracting company about this process or view these tips on American Home Shield.
