About our ductless mini-split installation service

If you have a hot bedroom over the garage, a finished attic that never cools down, or a home without ductwork, a ductless mini split is often the perfect solution. Each indoor head is independently controlled and whisper-quiet.

Mini-splits solve the problems this region keeps handing us: the un-ducted addition on a century home near Belle Ewart, the converted garage in Angus, the third-floor bedroom in a Newmarket Bayview-corridor house that the main system was never going to reach, and the four-season room off the back of a Cookstown bungalow. Cold-climate Mitsubishi and Daikin units hold rated output well below our January design temperature, which matters more here than it would an hour south.

Rebates: qualifying equipment can draw Ontario incentives and federal financing, and we prepare the paperwork with your quote. See current Ontario HVAC rebates.

Where we provide ductless mini-split installation

Innisfil is home base, and our trucks run the same routes daily across Simcoe County and north York Region.

  • Barrie Barrie's Kempenfelt Bay humidity makes correct sizing matter more than raw tonnage, especially in the west-facing Ardagh and Sunnidale homes.
  • Bradford West Gwillimbury Marsh humidity around Bradford loads a cooling system harder than the thermometer suggests, so we size for latent load, not just square footage.
  • Essa Farm and gravel dust across Essa fouls condenser coils quickly, which is why Angus and Thornton units lose capacity years before they should.
  • East Gwillimbury The newer East Gwillimbury builds have tight envelopes and big glazing, a combination that punishes an oversized air conditioner with short cycling.
  • Springwater Tree cover through Midhurst and Anten Mills keeps outdoor units cooler but drops leaf litter straight into them every autumn.
  • Newmarket Newmarket's mature neighbourhoods often have tight side-yard clearances, so condenser placement and service access get planned before install day.
  • Oro-Medonte Lakeside properties from Oro Station to Hawkestone deal with constant moisture off Lake Simcoe, which corrodes coils and contactors faster than inland.
  • New Tecumseth Alliston and Tottenham homes run long cooling seasons on open exposure, so we lean toward two-stage equipment that dehumidifies properly.
