Before You Call: Quick AC Diagnostic in Whitby
- Check thermostat — Set to COOL, temperature lower than current room temp, fan on AUTO. Change batteries if thermostat display is dim or blank.
- Check breaker panel — The AC breaker (typically 30–60A double-pole) may have tripped. Reset it ONCE. If it trips again immediately, stop and call us — do not reset a breaker that trips repeatedly.
- Check the air filter — A completely blocked filter can trigger the high limit switch and shut the system down as a safety measure.
- Check the outdoor disconnect — The outdoor disconnect box (typically on the wall near the outdoor unit) may have been pulled during a service visit or storm and not re-engaged.
If None of That Works: Most Likely Causes in Whitby
- Failed capacitor — Outdoor unit hums but doesn’t fully start; most common AC failure. Same-day fix ($180–$280).
- Failed contactor — Electrical relay that connects the compressor to power; no clicking from outdoor unit. Same-day fix ($160–$240).
- Control board fault — Indoor unit not communicating with outdoor unit; requires diagnosis.
My AC is not working in Whitby — what should I do?
First check: thermostat settings and batteries, breaker panel (reset once if tripped), air filter, and outdoor disconnect box. If these don’t restore operation, call Madina Mechanical at (416) 424-4328 for same-day diagnosis and repair. Most common causes (capacitor, contactor) are fixed same-visit.
