Why Is Your AC Blowing Hot Air in Whitby?
Thermostat Set to “Fan” Instead of “Auto”
Before calling anyone, check: if the fan is set to ON instead of AUTO, the blower runs continuously — including between cooling cycles when it’s just circulating uncooled air. Set fan to AUTO first.
Low Refrigerant (Leak)
With insufficient refrigerant, the compressor can’t absorb heat from indoor air. System runs, fan blows, but the air is warm. Fix: leak detection + repair + recharge ($120–$180/lb R-410A).
Failed Capacitor
If the compressor capacitor fails, the outdoor compressor won’t start properly — indoor fan still runs, blowing uncooled air. You may hear a humming outdoor unit but the compressor isn’t engaging. Most common AC repair ($180–$280), done same-visit.
Dirty Condenser Coil
Clogged condenser coil prevents heat rejection outdoors — the refrigerant returns to the indoor coil still warm, reducing or eliminating cooling. Coil cleaning restores full capacity ($150–$220).
Why is my air conditioner blowing hot air in Whitby?
AC blowing hot air in Whitby is most commonly caused by: low refrigerant (leak), failed start/run capacitor, dirty condenser coil blocking heat rejection, or thermostat fan setting left on ON instead of AUTO. All are diagnosable same-day. Madina Mechanical provides same-day AC repair in Whitby — call (416) 424-4328.
