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

  • Check thermostat to ensure your HVAC system maintains at a reasonable and comfortable level. You can save money by investing in digital thermostats to keep their homes warm in the winter and cool in the summer, and even turn on at specific times to lower energy usage.
  • Tighten all electrical connections. You can also measure currents and voltages of a system’s motors. Faulty electrical connections may result in unsafe operation, poor efficiency, and even electrical fires. University City HVAC contractors like Weis Comfort Systems note that poorly-functioning equipment reduces a systems’ life expectancy. Also check all of the HVAC system’s oil/gas connections and controls.
  • Lubricate all moving parts. "Dry" parts cause friction and rust. This usually results in increased workload and further decreases a system’s efficiency. You can always contact Weis Heating and Cooling for additional info about HVAC maintenance in University City.
  • Inspect the condensate line. Your air conditioner unit has to handle water. Ask an air conditioning contracting company about this process or view these tips on American Home Shield.
