Emergency Heating and Cooling Repair

Heating and cooling companies in University City like Weis know how difficult it may be for some homeowners to handle HVAC maintenance. 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 working condition:

  • Check your thermostat settings to make sure your HVAC system maintains at a comfortable and reasonable level. Property owners can cut down costs by investing in automated thermostats to keep their homes cool in the summer and warm in the winter, and even activate at set times to lower energy use.
  • Check electrical connections. You can also measure currents and voltages of a system's motors. Faulty electrical connections are known to cause unsafe operation, poor efficiency, and even electrical fires. University City HVAC businesses like Weis Comfort Systems point out that poorly-functioning equipment reduces a systems' life expectancy. Also look at all of the HVAC system's controls and oil/gas connections.
  • Lubricate all moving parts. "Dry" parts cause friction and rust. This usually results in increased workload and further decreases a home system's efficiency. You can always contact Weis Comfort Systems for more information about heating and cooling in University City.
  • Inspect the condensate line. Your air conditioner unit handles water. Ask your AC contracting company about this step or look at these tips on American Home Shield.

It's important to care for and monitor your HVAC systems.
