Concord HVAC Companies like Weis Comfort Systems know how challenging it may be for some homeowners to manage HVAC repairs. Here is our maintenance checklist to give you with a few go-to checks and tasks to keep your heating, cooling, and other systems functional:

  • Check thermostat to ensure your HVAC system stays at a reasonable and comfortable level. Property owners can save money 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.
  • Check electrical connections. You can also measure currents and voltages of a system’s motors. Faulty electrical connections can result in unsafe operation, poor efficiency, and even electrical fires. Concord HVAC companies like Weis Heating and Cooling note that poorly-functioning equipment lowers a systems’ performance expectancy. Also check all of the system’s oil/gas connections and controls.
  • Lubricate all moving parts. "Dry" parts lead to friction and rust. This usually results in increased workload and further decreases a system’s efficiency. You can always contact Weis Comfort Systems for more information about HVAC maintenance in Concord.
  • Inspect the condensate line. Your AC unit handles water. Ask an AC contracting company about this step or look at these tips on American Home Shield.

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