How to Choose the Right A/C Unit

The summer forecast for this year looks like it’s going to be a sweltering season across Canada. If you’re not prepared for the heat, now is the time to consider air conditioning repair in Red Deer or a new A/C unit altogether.

How do you know when to replace your A/C unit, and what should you look for? Discover the answers below as we go over important considerations.


Types of A/C Units

There are a few different types of A/C units to consider if you need a replacement or upgrade. These include:

  • Central A/C units
  • Window units
  • Portable units

Central A/C is one of the most popular types. Air is pumped through the house using ductwork. Most newer homes have central A/C.


Many people that live in apartments or older homes are familiar with window units. This type of A/C unit fits in your window and pushes cool air inside as it pulls hot air outside. Window A/C units aren’t as effective as central air conditioning, but they are cheaper.

Portable air conditioning units are meant to be brought from room to room or used to cool a small space. These units are small but nowhere near as effective as central A/C and not really useful for cooling a home.


Determine the Right Size

If you want to figure out the best A/C unit for your home, you need to calculate the square footage. You need an air conditioner with the right capacity if you want to keep your whole home cool.

You don’t want to buy an air conditioner that’s too small or too large for your home. A unit that’s too small will struggle to keep up with demands and work too hard, and one that’s too big can short-cycle.


Air conditioning units measure cooling capacity in tons. One ton is equivalent to 3.5 kW or 12,000 Btu/h. You can learn more about air conditioners here if you have any questions.

Are you feeling stumped? Talk to your local HVAC company to discuss your options and see what their technicians recommend for your home.



Make sure you consider your budget when planning for a new A/C unit. Weigh the pros and cons of upgrading to a more efficient type of air conditioning. For instance, central air conditioning costs more upfront but can save you big in the long run.

Energy-efficient units are better for the environment and generally last longer, therefore, resulting in lower energy bills.


Think about units with extra features, such as smart A/C units and “whisper quiet” units. These cost more but might be worth an investment.

Lastly, a broken A/C unit may simply need repairs. Before you start shopping, consider having a technician come out to take a look and see if anything can be fixed.
