Emergency Heating and Cooling Repair

Heating and cooling companies in O’Fallon like Weis understand how challenging it may be for homeowners to manage HVAC maintenance. 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 in serviceable condition:

  • Check your thermostat to ensure the HVAC system maintains at a reasonable and comfortable level. You can reduce power bills by investing in automated thermostats to keep their homes cool in the summer and warm in the winter, and even kick on at specific times to lower energy consumption.
  • Tighten electrical connections. You should also measure voltages and currents of a system’s motors. Bad electrical connections are known to result in electrical fires, poor efficiency, and unsafe operation. O’Fallon HVAC companies like Weis Comfort Systems note that poorly-functioning equipment lowers a systems’ performance expectancy. Also look at all of the HVAC system’s controls and oil/gas connections.
  • Lubricate all moving parts. "Dry" parts can create friction and rust. This usually results in increased workload and further decreases a system’s efficiency. Feel free to contact Weis Comfort Systems for additional info about heating and cooling in O’Fallon.
  • Check the condensate line. Your AC unit has to handle water. Ask an air conditioning contracting company about this step or view these guidelines on American Home Shield.
