Ductless air conditioning systems are an economical option for adding permanent air conditioning to homes that do not have ductwork installed. Many older homes in Toronto  have only baseboard heating or radiators installed. Without existing ductwork adding a central air conditioner to these homes can be expensive.

A ductless air conditioner installed in your home allows you to avoid the hassle of having to install air conditioners in your windows every year and then take them down again at the end of the season. Window units are heavy, they take up storage space during the off-season, and they provide a security risk to your home. A ductless unit will often be much more energy efficient than a window unit. Additionally many units work in reverse in winter, absorbing heat from the outside air and moving it indoors to heat your home. This supplemental heating and cooling can be an incredibly energy efficient heating and cooling solution for you.

Components of Ductless Split System

A ductless air conditioning system takes up very little room inside your home. It is referred to as mini split or a ductless split system because it consists of two components:

  • A compressor unit that is installed outside your home on a concrete slab
  • An indoor unit that contains a fan, which is installed near the ceiling on an exterior wall in the area to be cooled

Copper refrigerant lines connect the two units through holes that are drilled and run through the wall. Electricity is supplied to the indoor unit from the outdoor unit, so no additional wiring is need in that room.

How the Room is Cooled

Once the ductless air conditioner is turned on, it works pretty much in the same way a regular central air system would work. The only exception is that it works without the ductwork and additional equipment that would be installed in the home for central air.

The outdoor compressor unit pumps and cools the system’s refrigerant through the copper lines to the indoor unit. The fan inside the unit turns and distributes the cool air throughout the air. Cool air is heavier than warm air, therefore the cooled air drops, while the warmer air rises.

The warm air is retrieved through the indoor unit and removed along with condensation that may have collected inside the unit back out to the compressor through the copper lines.

Additional Advantages

With a ductless split system, you could:

  • Install multiple units for zoned air conditioning and only cool specific areas within your home
  • Easily keep a consistent temperature in the rooms cooled by the system
  • Improve the air quality within your home
  • Use less electricity and experience less noise than you would with other HVAC system options

Ductless air conditioning is an ideal solution for:

  • Heritage homes and homes without ducts
  • Warm bedrooms
  • Garages and workshops
  • Spot cooling for areas in your home poorly served by existing ductwork
  • Additions with electric baseboard heaters
  • Cooling and heating for additions
  • Humidity control and temperature control for upper floor rooms
