Lemay HVAC Companies like Weis Heating and Cooling understand how challenging it may be for some homeowners to handle HVAC repairs. Below you will find a maintenance checklist to provide you with a few go-to checks and tasks to keep your heating, cooling, and other systems working:

  • Check your thermostat settings to ensure your cooling and heating system stays at a comfortable and reasonable level. Homeowners can cut down costs by investing in digital 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.
  • Check electrical connections. You can also measure currents and voltages of a system’s motors. Bad electrical connections may result in electrical fires, poor efficiency, and unsafe operation. Lemay HVAC contractors like Weis 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 components. "Dry" parts lead to friction and rust. This usually results in increased workload and further reduces a system’s efficiency. Call Weis for more information about HVAC maintenance in Lemay.
  • Inspect the condensate line. Your AC unit handles water. Ask an air conditioning contracting company about this process or look at these tips on American Home Shield.

It is important to monitor and care for your heating and cooling systems.
