Expert Insights
Pro Tips: Central AC Repair in O'Fallon
Before calling a technician, these checks can save time and help you describe the problem accurately.
Check Zone Dampers
If certain rooms are always too hot or cold, a stuck zone damper or failed control board is likely. A zoning specialist can diagnose it quickly.
Open All Vents and Returns
Closed supply or return vents increase system static pressure, overwork the blower, and reduce efficiency significantly. Ensure all are fully open.
Clean the Condenser Coils
Dirty condenser coils force the compressor to work harder and overheat. Annual low-pressure rinse with a garden hose extends compressor life.
