Beat the Heat: Your Ultimate Guide to Air Conditioning Pt. 1

As a homeowner in Canada, you understand the importance of a dependable air conditioning system during the sweltering summer months.

With a vast array of choices, it can be challenging to figure out which air conditioning system fits your requirements. To assist you in making a well-informed choice, we have compiled this all-inclusive guide covering the various air conditioning systems available.

In this article, we’ll discuss the pros and cons of each type, their energy efficiency, and how they work so that you can choose the best air conditioning system for your home.

1. Central Air Conditioning Systems

Central air conditioning systems are Canada’s most common type of air conditioning. They consist of an outdoor unit, an indoor unit, and a series of ducts that distribute cool air throughout the home.

The outdoor unit contains the compressor and condenser, which cools the refrigerant and sends it to the indoor unit, usually in the basement or attic. The indoor unit then uses a fan to blow the cooled air through the ducts and into the house’s various rooms.


It provides even cooling throughout the home
A central thermostat can control it
It can be combined with central heating for year-round comfort


Requires ductwork, which can be expensive to install or retrofit
It can be less energy efficient than ductless systems, especially in older homes with poor insulation

2. Ductless Mini-Split Systems

In Canada, ductless mini-split systems, sometimes called ductless heat pumps, are gaining popularity because they are energy-efficient and easy to install.

These systems have an outdoor unit and one or more indoor units that can be placed on walls or ceilings. A small conduit connects the indoor and outdoor units, containing the refrigerant lines, power cables, and condensate drain.


Highly energy efficient, which can lead to significant cost savings on your energy bills
No need for ductwork, making them easier and less expensive to install in homes without existing ducts
Allows for individual temperature control in each room, providing personalized comfort


It may require multiple indoor units to adequately cool larger homes, which can increase the overall cost
Aesthetically, the indoor units may not be as visually appealing as other options

3. Window Air Conditioning Units

Window air conditioning units are popular for those looking for a more affordable and temporary cooling solution. As the name suggests, these units are installed directly into a window or through a hole in an exterior wall. They draw in warm air from the room, cool it with a refrigerant, and then blow the cooled air back into the room.


Affordable and easy to install, making them a popular option for renters and those on a budget
Can be easily removed and reinstalled in different rooms or homes as needed


Limited cooling capacity, making them less suitable for larger homes or areas with high heat loads
It can be noisy and less energy-efficient than other options

4. Portable Air Conditioning Units

Portable air conditioning units are free-standing and can be moved from room to room. They operate similarly to window units but do not require a window for installation. Instead, they use an exhaust hose that must be vented through a window or an exterior wall.


Flexible and convenient, as they can be easily moved to different rooms as needed
No permanent installation is required, making them suitable for renters or temporary cooling needs


Generally less energy-efficient than other options
Limited cooling capacity and may struggle to cool larger rooms or areas with high heat loads
It can be noisy and may require frequent emptying of the condensate collection tray


Selecting the appropriate air conditioning system for your house can greatly impact your comfort and energy expenses. It’s essential to know the distinctions between central air conditioning, ductless mini-split systems, window units, and portable units to choose to cater to your requirements and financial plan.
