Creve Coeur HVAC Companies like Weis Heating and Cooling know how difficult it is for some homeowners to manage HVAC repairs. Below you will find a maintenance checklist to provide you with a handful of go-to checks and tasks to keep your cooling, heating, and other systems functional:

  • Check your thermostat settings to make sure the HVAC system maintains at a comfortable and reasonable level. Homeowners 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.
  • Tighten electrical connections. You should also measure voltages and currents of a system's motors. Bad electrical connections may result in unsafe operation, poor efficiency, and even electrical fires. Creve Coeur HVAC companies like Weis Heating and Cooling note that poorly-functioning equipment reduces a systems' performance expectancy. Also check all of the HVAC system's oil/gas connections and controls.
  • Lubricate moving components. "Dry" parts cause friction and rust. This may result in increased workload and further decreases a system's efficiency. You can always contact Weis Heating and Cooling for more information about HVAC maintenance in Creve Coeur.
  • Check the condensate line. Your air conditioner unit has to handle water. Ask an AC contracting company about this step or look at these tips on American Home Shield.

It is important to monitor and care for your heating and cooling systems. Weis, one of the leading HVAC companies in Creve Coeur, is here to help homeowners maintain HVAC systems to improve efficiency, reduce costs, and increase longevity.
