In this expert guide from For Saving Home Services Inc, discover why your AC isn’t managing humidity, what you can do to fix it, and how professional air conditioner installation Greater Toronto can give you real comfort and peace of mind.
The Science Behind AC Cooling and Humidity Control
How Air Conditioners Are Supposed to Remove Humidity
A central air conditioner doesn’t just cool your home—it also removes humidity. As your system pulls warm indoor air across its cold evaporator coil, water vapor in the air condenses into liquid and is drained away. This process, called dehumidification, is crucial for comfort during humid Toronto summers.
Why Cooling Alone Isn’t Enough
If your AC is running but the air still feels clammy, the dehumidification process isn’t working as it should. This can happen if:
The AC is oversized, cooling the home too fast to remove moisture
The unit is old, dirty, or low on refrigerant
The evaporator coil isn’t cold enough, or the drain lines are clogged
Why High Indoor Humidity Is a Problem for GTA Homes
High humidity isn’t just uncomfortable. It can:
Cause mold and mildew to grow on walls, ceilings, and furniture
Worsen allergies, asthma, and respiratory issues
Lead to musty odors and increased dust mites
Make your AC work harder, increasing your energy bills
For a healthy home, indoor humidity should stay between 30%–50%—especially during Greater Toronto’s humid summers.
Top Reasons for High Humidity Even When Your AC Is On
Oversized or Improperly Installed Air Conditioner
An AC that’s too large cools air quickly but doesn’t run long enough to remove humidity. Proper sizing and professional air conditioner installation in Greater Toronto are crucial for effective humidity control.
Aging or Poorly Maintained Equipment
Dirty coils, worn parts, or low refrigerant prevent the system from removing moisture efficiently.
Tip: Schedule annual professional maintenance to keep your AC’s moisture removal working at peak performance.
Poor Home Sealing and Insulation
Leaky windows, doors, or ductwork allow humid outdoor air to seep inside, overwhelming your AC.
Extreme Outdoor Humidity
On the stickiest days, even a properly installed system can struggle. A dedicated whole-home dehumidifier can be a smart solution for Greater Toronto homes.
