Shrewsbury HVAC Companies like Weis Comfort Systems understand how challenging it may be for some homeowners to manage HVAC repairs. Below you will find a maintenance checklist to provide you with a few go-to checks and tasks to keep your heating, cooling, and other systems working:

  • Check your thermostat to ensure the cooling and heating system maintains at a reasonable and comfortable level. You can save money by investing in automated thermostats to keep their homes cool in the summer and warm in the winter, and even turn on at set times to lower energy usage.
  • Check all electrical connections. You should also measure voltages and currents of a system’s motors. Faulty electrical connections are known to cause electrical fires, poor efficiency, and unsafe operation. Shrewsbury HVAC contractors 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 lead to friction and rust. This usually results in increased workload and further reduces a system’s efficiency. Call Weis Comfort Systems for additional information about HVAC maintenance in Shrewsbury.
  • Inspect the condensate line. Your air conditioner unit has to handle water. Ask an air conditioning contracting company about this process or look at these guidelines on American Home Shield.

It is important to care for and monitor your HVAC systems. Weis Comfort Systems, one of the leading HVAC companies in Shrewsbury, is here to help homeowners maintain these systems to improve efficiency, reduce costs, and increase longevity.
