Why Humidity Is a Big Issue in Toronto Condos
Toronto’s climate brings humid summers and dry winters, creating indoor comfort challenges especially for condo and apartment dwellers. High humidity can lead to:
- Musty odors
- Mold and mildew growth
- Condensation on windows
- Damage to walls, floors, and furniture
- Aggravated allergies and respiratory issues
In compact condo spaces, humidity problems tend to intensify because of limited ventilation, high occupancy rates, and the building’s overall airflow design.
Luckily, with the right HVAC strategies, you can control moisture levels and maintain a healthier, more comfortable living environment.
Ideal Indoor Humidity Levels for Condos
Maintaining the right humidity balance is key. The optimal indoor relative humidity (RH) should be:
- In summer: 40%–50%
- In winter: 30%–40%
Levels above 50% can encourage mold and dust mites, while levels below 30% can cause dry skin, respiratory discomfort, and static electricity.
Tip: Invest in an affordable hygrometer to monitor your condo’s humidity year-round.
Signs Your Condo Has a Humidity Problem
If you’re unsure whether humidity is an issue in your unit, watch for these signs:
- Persistent condensation on windows
- Musty or damp smells
- Peeling paint or wallpaper
- Warped wood flooring
- Visible mold spots, especially around bathrooms or windows
If you spot any of these, it’s time to take action.
HVAC Tips to Combat Condo Humidity
1. Use Your HVAC System’s Dehumidification Features
Modern HVAC systems often have a “dry” or dehumidification mode that removes moisture without dramatically changing the temperature. If your condo unit has this feature, use it during humid days.
If not, running the air conditioning can also lower humidity naturally, as AC units remove moisture while cooling the air.
2. Install a Standalone Dehumidifier
For condos without central dehumidification, a portable dehumidifier can make a huge difference, particularly in:
- Bedrooms
- Bathrooms
- Closets
- Laundry areas
Choose a model rated for your square footage and remember to empty the tank regularly, or connect it to a drain if possible.
3. Upgrade Your HVAC Filter
A high-quality HVAC filter (MERV 11 or higher) can help manage airborne moisture by trapping dust, mold spores, and allergens that thrive in humid environments.
Better filtration also improves your system’s efficiency and can reduce wear on your HVAC equipment.
4. Use Exhaust Fans Consistently
Condos often have limited natural airflow, making bathroom and kitchen exhaust fans critical tools for humidity control.
- Run the bathroom fan during and after showers for at least 20 minutes.
- Use the kitchen exhaust fan while cooking, especially when boiling water.
- Ensure fans vent to the outside rather than recirculating air internally.
If your condo’s fans are old or weak, consider upgrading to ENERGY STAR® rated models for better performance.
5. Seal Windows and Doors
High humidity can infiltrate your condo through poorly sealed windows or sliding doors. Check for:
- Drafts around window frames
- Gaps under doors leading to balconies
- Cracks in caulking or weatherstripping
Proper sealing not only keeps moisture out but also improves energy efficiency.
6. Consider a Ductless Mini-Split System
For condos without central air, a ductless mini-split system with dehumidification mode can help maintain comfort year-round without bulky equipment.
Benefits of mini-splits include:
- Precise humidity and temperature control
- High energy efficiency
- Quiet operation
- Easy installation in condos and apartments

Frequently Asked Questions About Condo Humidity
Can I install a whole-home dehumidifier in a condo?
In most cases, standalone or portable dehumidifiers are a better fit for condos, but mini-split systems with dehumidification features offer a similar effect.
Does running the AC help lower humidity?
Yes. Air conditioners naturally dehumidify the air as part of the cooling process, making them an important tool in humid months.
Should I run my bathroom fan even when I’m not showering?
If your condo feels particularly damp, running the fan intermittently during humid periods can help maintain balanced moisture levels.
What’s the best humidity level for sleeping?
For optimal comfort and health, aim for indoor humidity between 40% and 50% while sleeping.
