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

  • Check your thermostat settings to ensure the HVAC system stays at a reasonable and comfortable level. Homeowners can reduce power bills 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 consumption.
  • Check all electrical connections. You should also measure currents and voltages of a system’s motors. Faulty electrical connections can result in unsafe operation, poor efficiency, and even electrical fires. Shiloh HVAC contractors like Weis Comfort Systems note that poorly-functioning equipment reduces a systems’ performance expectancy. Also check all of the HVAC system’s controls and oil/gas connections.
  • Lubricate all moving parts. "Dry" parts cause friction and rust. This usually results in increased workload and further reduces your system’s efficiency. Call Weis for more info about HVAC maintenance in Shiloh.
  • Inspect the condensate line. Your AC unit needs to manage water. Ask your AC contracting company about this process or view these guidelines on American Home Shield.

It’s important to monitor and care for your HVAC systems. Weis Heating and Cooling, one of the leading HVAC companies in Shiloh, is here to help homeowners maintain these systems to improve efficiency, reduce costs, and increase longevity.
