Residential Air Conditioning

The evolution of residential air conditioning began, for most Canadians, with the air-cooled, window air conditioner.

The residential window air conditioner quickly gave way to other forms of air-cooled unitary equipment, for residential and small commercial air conditioning applications – through-the-wall and roof-top unitary designed equipment.

Within their limited capacity, the through-the-wall, unitary air conditioner, with provision for automatic temperature control, electric space heating, outside air make-up and exhaust, louvered air distribution control, as well as cooling, would be an essential step, part of the advance guard in the development of other forms of year-round air conditioning in Canada, for residential and small commercial applications.

The technology would be seen as beginning to build public expectations and market demand for health and comfort as a spring board for the development of much more elaborate equipment targeted on the residential and small commercial market.

Early Window Air Conditioner

In many ways the air cooled, unitary air conditioner for through-the-window, through-the-wall, and through-the-roof installation, provided the elemental model on which the residential and small commercial equipment market evolved.

Variously equipped with automatic temperature control, out-side air inlet and exhaust damper, air filter and diffusers, and often with supplementary electric heater this technology, within its ability to do so, would satisfy the mid 20th century definition of “air conditioning“.
