Air Conditioner Installation in Toronto & the GTA
Direct Air Systems is an authorized Lennox and Mitsubishi dealer installing central air conditioners and ductless mini-splits across the GTA.
Central AC vs. Ductless Mini-Split
Central Air Conditioner (Ducted)
Connects to your existing furnace ductwork. One outdoor compressor cools your entire home. Best for homes with existing forced-air systems. Lennox central AC units range from 13.4 SEER2 (Merit) to 23.2 SEER2 (Signature XC21).
Ductless Mini-Split (Mitsubishi or Lennox)
No ductwork required. Ideal for homes without ducts, room additions, or targeted cooling. Mitsubishi ductless systems reach up to 33.1 SEER2.

What Is Included in Our AC Installation Service

Consider a Heat Pump Instead of AC
Many GTA homeowners now choose a Lennox cold-climate heat pump which provides both heating and cooling. Combined with a Lennox gas furnace for backup heat, a dual-fuel hybrid system delivers the best year-round efficiency and may qualify for Ontario rebates.
