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

  • Check thermostat settings to make sure the HVAC system stays at a reasonable and comfortable level. Homeowners can reduce power bills by investing in digital thermostats to keep their homes cool in the summer and warm in the winter, and even turn on at set times to lower energy consumption.
  • Tighten electrical connections. You should also measure currents and voltages of a system’s motors. Bad electrical connections are known to cause unsafe operation, poor efficiency, and even electrical fires. Barnhart HVAC companies like Weis Comfort Systems point out that poorly-functioning equipment lowers a systems’ life expectancy. Also check all of the system’s oil/gas connections and controls.
  • Lubricate moving components. "Dry" parts cause friction and rust. This usually results in increased workload and further decreases a system’s efficiency. You can always contact Weis Comfort Systems for additional information about HVAC maintenance in Barnhart.
  • Inspect the condensate line. Your AC unit has to handle water. Ask your AC contracting company about this step or look at these tips on American Home Shield.
