New Athens HVAC Companies like Weis Heating and Cooling know how challenging it may be for some homeowners to manage HVAC repairs. Below you will find a maintenance checklist to give you with a handful of go-to tasks and checks to keep your cooling, heating, and other systems working:

  • Check thermostat to ensure the HVAC system maintains at a reasonable and comfortable level. Homeowners can save money by investing in automated thermostats to keep their homes warm in the winter and cool in the summer, and even turn on at set times to lower energy usage.

Also check all of the system’s controls and oil/gas connections.
  • Lubricate all moving parts. "Dry" parts lead to friction and rust. This may result in increased workload and further decreases a system’s efficiency. Call Weis Heating and Cooling for more info about HVAC maintenance in New Athens.
