If you live in an older Toronto home, a heritage property, or a condo that wasn’t built with central air in mind, you already know the struggle. Window units are noisy and inefficient. Portable ACs are clunky. And traditional central air? That would mean tearing down walls to install bulky ductwork.
Enter SpacePak. It’s a high-velocity, small-duct HVAC system designed specifically for homes where conventional ductwork isn’t practical. This guide breaks down how SpacePak works, how it compares to other systems, and why it’s becoming a go-to solution for Toronto homeowners. No sales pitch. Just practical information.
What Is a SpacePak System?
SpacePak is a central heating and cooling system that uses small, flexible 2-inch ducts instead of the large metal ductwork found in traditional systems . These tiny tubes can be threaded through walls, floors, and ceilings with minimal disruption to your home’s structure.
The system works on a principle called “high-velocity” air delivery. Instead of slowly pushing air through large ducts, SpacePak moves air quickly through small tubes, creating a gentle mixing effect called “aspiration” that ensures even temperatures in every room .
Key features include:
Compact air handler – Small enough to fit in a closet, attic, basement, or crawlspace
Discrete vents – 5-inch round outlets that blend with any decor
Heating capability – Can be paired with heat pumps, boilers, or electric coils for year-round comfort
Superior humidity removal – Removes 30% more humidity than conventional systems, allowing you to feel cooler at higher thermostat settings
Why SpacePak Is Ideal for Toronto Homes
Toronto’s housing stock includes many older homes, heritage properties, and condos that simply weren’t designed for traditional ductwork. SpacePak addresses this gap without compromising aesthetics or comfort.
SpacePak is particularly well-suited for :
Heritage homes – Where preserving original features is a priority
Homes with no existing ductwork – Eliminates the need for major renovations
Homes with limited mechanical space – The compact air handler fits in tight spaces
Design-savvy renovations – Near-invisible ducts maintain clean sightlines

SpacePak vs. Mini-Split vs. Conventional Central Air
Not sure which system is right for your home? Here’s an honest comparison :
| Feature | SpacePak System | Mini-Split System | Conventional Central Air |
|---|---|---|---|
| Ductwork Required | Small, flexible tubing | None | Large metal ductwork |
| Best For | Older homes, condos, heritage properties | Homes without ducts, room additions, small spaces | Newer homes with existing ducts |
| Aesthetic Impact | Virtually invisible, hidden ducts | Visible wall-mounted units | Large vents and bulky ductwork |
| Installation Complexity | Moderate – small ducts, no major renovations | Simple – wall-mounted units | High – requires full ductwork |
| Noise Level | Very quiet – air handler isolated, ducts insulated | Indoor unit fan noise | Airflow noise through ducts |
| Heating Capability | Works with heat pumps and boilers | Works with heat pumps | Works with furnaces |
| Cost | Mid-to-high range | Mid-range | High |

SpacePak installation is more involved than a simple mini-split setup but far less invasive than traditional ductwork. Here’s what the process typically looks like:
Before Installation:
A certified SpacePak installer assesses your home’s layout
The air handler location is determined (attic, basement, or crawlspace)
Duct routes are planned through walls, ceilings, and floors
Installation:
2-inch flexible ducts are fed through existing cavities
The compact air handler is mounted in the chosen space
Outdoor condenser unit is connected
System is tested and calibrated
Typical Pricing in the GTA :
Equipment: $3,000 – $7,000
Installation: $2,000 – $5,000
Total: $5,000 – $12,000+
GTA average: $7,000 – $9,500+ depending on system complexity
Only certified SpacePak installers should handle these systems to ensure proper performance, warranty coverage, and code compliance. SpacePak strongly recommends professional installation .
