Ballwin HVAC Companies like Weis understand 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 your thermostat to make sure the HVAC system stays at a reasonable and comfortable level. You can cut down costs by investing in automated thermostats to keep their homes warm in the winter and cool in the summer, and even kick on at set times to lower energy consumption.
