Pro Tips: Furnace Repair in Ontario
Before calling a technician, these checks can save time and help you describe the problem accurately.
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.
Check the Air Filter
A clogged filter is the #1 cause of reduced airflow, frozen coils, and system overheating. Replace it every 1-3 months depending on usage.
