Air Conditioner Installation in Toronto & the GTA

Direct Air Systems installs central air conditioners and ductless mini-splits for homes across Toronto, Markham, Vaughan, Brampton, Mississauga, Richmond Hill, Newmarket and Bolton. We supply and install Lennox central air conditioning and Mitsubishi ductless systems, size every system to your home, and start with a free in-home assessment and a written quote.

What Air Conditioner Installation Includes

• Free in-home assessment: we look at your home, ductwork and electrical supply and give you a written quote.
• Correct sizing: an air conditioner has to match your home's cooling load. We use a heat-load (Manual J) calculation instead of sizing by rule of thumb, because an oversized unit short-cycles and handles humidity poorly.
• Equipment installation: outdoor unit, indoor coil or air handler, refrigerant lines, condensate drain and a dedicated electrical connection.
• Start-up and testing: refrigerant charge, airflow and thermostat setup are checked before we leave.
• Warranty registration: manufacturers require registration for full warranty coverage, and we handle it with you.
• Removal of your old unit.

Central Air Conditioner or Ductless Mini-Split?

A central air conditioner uses your home's existing ductwork and cools the whole house from one outdoor unit, so it suits homes with a forced-air furnace. A ductless mini-split has no ducts: an outdoor unit connects to one or more indoor units by refrigerant lines, which suits additions, homes without ductwork and rooms that need their own control.

Brands We Install

• Lennox central air conditioners: Signature, Elite and Merit series, from entry-level models to higher-efficiency, quieter units. See the Lennox and Mitsubishi air conditioner models we offer.
• Mitsubishi ductless mini-splits: single-zone and multi-zone systems for homes without ductwork or rooms that need their own comfort control.

Air Conditioner or Heat Pump?

If your air conditioner is due for replacement, it is worth comparing it with a heat pump, which cools the same way and also heats. Our heat pump vs air conditioner guide explains the differences, and our Lennox heat pump installation page covers the cold-climate models we install.

What Does Air Conditioner Installation Cost?

The price depends on the size of the system, the model, your existing ductwork and electrical supply, and whether you choose central or ductless. We give you a written quote after a free in-home assessment, so you see the full installed price before any work starts. Our air conditioner installation cost guide explains what drives the cost.

Frequently Asked Questions

How long does air conditioner installation take?

Many central air conditioner replacements are completed in a day. Ductless installations depend on the number of zones and the layout. We confirm the timing at your assessment.

What size air conditioner does my home need?

It depends on your home's heat load, not only its square footage. Windows, insulation, ceiling height and sun exposure all matter, which is why we use a heat-load calculation rather than a rule of thumb.

What is the difference between a central air conditioner and a ductless mini-split?

A central air conditioner uses your existing ductwork and cools the whole house from one outdoor unit. A ductless mini-split needs no ducts: an outdoor unit connects to one or more indoor units by refrigerant lines, which suits additions, homes without ductwork and rooms that need their own control.

Should I get an air conditioner or a heat pump?

An air conditioner only cools, while a heat pump cools and also heats. A heat pump costs more upfront and can reduce how much your furnace runs, and heat pumps have been eligible for Ontario rebates that stand-alone air conditioners have not. See our heat pump vs air conditioner guide for the full comparison.

Do I need a permit to install an air conditioner?

Requirements depend on the work and your municipality. Technicians who handle refrigerant must hold the required Ontario certification, and some installations need electrical work or permits. We confirm what applies to your home at the assessment.
