We properly size your system for even cooling and efficiency, complete a clean and professional installation with minimal disruption, and provide quality checks at every step.
High-velocity cooling for older Toronto homes with SpacePak
If your home doesn’t have existing ductwork - or you want central AC without major renovations - SpacePak offers the ideal solution. Designed specifically for older Toronto and East York homes, SpacePak delivers quiet, even cooling through small, discreet ducts that fit inside walls, closets, and ceilings.
SpacePak uses a high-velocity air handler and narrow flexible ducts, allowing it to provide full central cooling where traditional systems can’t be installed. It’s ideal for homes that want the comfort of central AC, without losing space to bulkheads or large ducts.
