Arnold HVAC Companies like Weis Comfort Systems understand 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 working:

  • Check your thermostat settings to make sure your HVAC system stays at a reasonable and comfortable level. Property owners can save money 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 usage.
  • Check electrical connections. You can also measure voltages and currents of a system’s motors. Faulty electrical connections may cause electrical fires, poor efficiency, and unsafe operation. Arnold HVAC contractors like Weis Comfort Systems point out that poorly-functioning equipment lowers a systems’ performance expectancy. Also check all of the system’s oil/gas connections and controls.
  • Lubricate all moving components. "Dry" parts cause friction and rust. This may result in increased workload and further reduces your system’s efficiency. Call Weis for additional info about HVAC maintenance in Arnold.
