Clearing Up Common AC Installation Misunderstandings

Air conditioning is the most common way Canadians cool their homes, especially during the summer months. However, many homeowners have misconceptions about AC installation that could result in costly mistakes. This article will explore some common misconceptions about AC installation and provide accurate information to help you make informed decisions.

#1: All AC Units Are the Same 

One common misconception about AC installation is that all air conditioning units are the same. This is not true. There are different types of units, such as central air conditioning, window units, and ductless mini-split systems. Each type of AC unit has different installation requirements, costs, and benefits.

The most common type used in Canada is central air conditioning. However, it requires ductwork, which can be expensive to install if your home does not already have it. Window units are a more affordable option, but they only cool one room at a time. Ductless mini-split systems are a newer option that can cool multiple rooms without ductwork. Before choosing an AC unit, it is important to consider your home’s size, layout, and budget.

#2: DIY Installation Is Easy

Another common misconception about AC installation is that it is easy to install a unit yourself. While some homeowners may have experience with DIY projects, AC installation is a complex process that requires specialized knowledge and tools. Incorrectly installing an air conditioning unit can result in costly repairs or even pose a safety risk.

Hiring an expert for AC installation guarantees the proper and secure setup of your air conditioning system. A skilled installer will make sure the unit is suitable for your house, set it up as per the manufacturer’s guidelines, and examine it to confirm it functions efficiently. Hiring a professional installer can be a time and money saver while also preventing potential issues down the line.

#3: Bigger Is Better

When it comes to air conditioning units, some homeowners believe that bigger is better. However, this is not true. An AC unit that is too big for your home can result in high energy bills, poor humidity control, and frequent repairs. If your unit is too small, then it may not cool your home adequately, resulting in discomfort and high energy bills.

To determine the right size AC unit, consider factors such as your home’s square footage, insulation, and the number of windows. A professional AC installer can help you determine the right size for your home.

#4: You Only Need to Replace Your AC Unit When It Breaks Down

Another common misconception about AC installation is that you only need to replace your unit when it breaks down. However, air conditioning systems have a lifespan and become less efficient over time. An older AC unit may not cool your home as effectively, resulting in higher energy bills and discomfort.

Upgrading your AC system before it fails can lead to long-term financial savings. Modern systems consume less energy, which can reduce your electricity costs. Furthermore, you might be able to receive rebates or incentives from the government or power companies for installing a newer AC unit.

#5: AC installation Is Expensive

Finally, some homeowners believe that AC installation is expensive and not worth the investment. While AC installation can be costly, the benefits of having a properly functioning AC unit can outweigh the initial investment. A properly installed AC unit can keep your home comfortable, improve indoor air quality, and reduce energy bills.

Additionally, there are ways to reduce the cost of AC installation. Some utility companies offer rebates or incentives for upgrading to a more energy-efficient AC unit. Additionally, financing options may be available to help you spread out the cost of AC installation over time.


AC installation can be a complex process, and there are many misconceptions about it that could result in costly mistakes. Remember to work with a professional AC installer, choose the right size of unit for your home, and consider the long-term benefits of upgrading your unit.
