Keeping you cool during the hot summers

Providing reliable cooling systems for over 30 years

We select quality, energy star rated air conditioning systems for your home that are built to last. If it wouldn’t go in our home – it’s not good enough for yours. Whether you are looking for single speed cooling, two-speed cooling or variable-speed cooling – we can provide an air conditioner that is right for your home. Four Seasons is dedicated to working with our wholesalers and manufactures to offer the most reliable air conditioning systems with the best performance for your cooling needs. Check out our Trane and Napoleon air conditioning models below:

How does air conditioning work?

Air conditioning cools your home by removing heat and humidity from the air using a liquid called refrigerant, which is circulated through the A/C compressor and coil. The A/C system converts refrigerant from a gas to liquid, circulating through the system. Your furnace fan then circulates cool air created by the A/C as the refrigerant liquid is transformed into vapor converting hot air into cold air.

SEER Rating - Seasonal Energy Efficiency Rating

When purchasing a new air conditioner an important factor to consider is the SEER rating. SEER stands for Seasonal Energy Efficiency Rating, this tells you how efficiently the unit will cool your home throughout an entire cooling season. SEER rating is a maximum efficiency rating, similar to km per liter rating for your car. Your car may get 8 liters per 100 km, but if you are stuck in traffic it could be lower. If your air conditioner is 21 SEER, that’s its maximum efficiency.

SEER2 - new energy efficecny rating standards

SEER2 is the new standard for measuring the Seasonal Energy Efficiency Rating in cooling equipment including air conditioners and/or heat pumps. This rating is determined with a more precise way of testing the equipment that takes into account a wider range of operating conditions and performance factors, including part load efficiency and the impact of variable speed blowers, this is done using the “M1 bower testing procedure”. Unlike the previous SEER rating, SEER2 can more accurately measure the real life performance of the equipment, giving a more precise reading of the units energy efficiency rating. 

In 2023, the minimum efficiency standards changed in response to the new standards set by the DOE (Department of Energy) in the United States. Although this has not been regulated in Canada yet, we are now seeing only SEER2 equipment being imported from the U.S. where all air conditioning equipment is manufactured. As the energy efficiency standards increase with SEER2 equipment, so does the cost on those units due to the new minimum efficiency requirement.

How is the SEER rating determined for your home?

There are many factors that determine which SEER is appropriate for your home. The size of your home, which direction is it facing or even your ductwork can affect energy use. It is also important to know the rating of an outdoor unit needs to be compatible with the indoor unit, your furnace. Incompatible systems will not work efficiently and can lead to operating issues.

This is why it is important to have a qualified installer visit your home to do a proper evaluation of your HVAC system to determine the cooling right equipment for you. We help you with that, contact us for your free home evaluation and estimate.


New to Alberta, air source heat pumps are becoming an increasingly popular choice for cooling for a few different reasons. Not only do these unit bode a high SEER rating from 19-20, they also offer supplemental heating in mild temperatures. This allows you to diversify your heating system while enjoying the highest efficiency for cooling available on the market today.
