Residential Air Conditioning Systems

Heating and air conditioning units come in all shapes and sizes, from small, portable units to industrial-sized ones. Residential air conditioning systems fall somewhere in between, the choice of which depends on factors such as the size of your home, its existing insulation, and available space for installation.

Here is an overview of the typical air conditioning systems you’ll find in today’s homes:

Window Air Conditioner

This is the most common type of residential air conditioning system installed in single rooms. All parts, including the compressor, condenser, and both evaporator and cooling coils are enclosed in a single unit. These air conditioning units are installed in a slot on the wall, or more commonly, through a windowsill, hence the name. The area where the unit meets the wall opening must be sealed to prevent heat intrusion and ensure air conditioner efficiency.

Split Air Conditioner

Split air conditioners are comprised of an outdoor unit and indoor unit. The outdoor unit is installed outside the room as a free-standing unit and contains the compressor, condenser, and expansion valve. The much smaller indoor unit is installed on a wall and houses the evaporator and cooling coils, as well as the cooling fan itself.

Unlike window-mounted units, split air conditioners require a much smaller hole to accommodate the connecting piping. This allows more flexibility with unit placement, as you can have the outdoor unit installed out of sight, even on a flat roof. Certain air conditioning systems even have a built-in heating element that generates heat during cold days and blows it into the room.

Packaged Air Conditioner

If you need to cool more than one room or even the entire house with a single unit, consider getting a packaged air conditioner instead. The single-unit setup has all components housed in a single box like its window-mounted counterpart, with the cool air blown through the ductwork using a high-capacity blower. Another kind of setup is similar to a split AC, but with several indoor units attached to a central outdoor unit.

With temperatures changing drastically, an air conditioner becomes almost a necessity in every household. Air conditioners come in various cooling capacities such as 1 ton, 1.5 ton and 2 tons.
