How to choose your air conditioning?


Choosing your air conditioning system is something you should spend time on. You need to look for some features that will improve your overall experience. There is no need to buy the most powerful unit available on the market. If you buy the most powerful unit you can find, you will cool your room with too much power and you will need to turn it off and on and off.
By doing so you will increase your electricity bill and we don’t want that. We want to save energy.

1°. The power.

The air conditioner ability to cool down is measured in British Thermal Unit per hour (BTU/h).
The bigger the room, the more BTU you will need. In order to know how many BTU you will need for your room you can use our BTU calculator tool.

2°. Energy efficiency.

Another really important feature you will need to look for is the energy efficiency. The SEER rating (Seasonal Energy Efficiency Ratio) is used to measure it. The higher the SEER, the lower the electric consumption will be. This information is often used to decide between two products that have similar features or price.

Furthermore, a product rated Energy Star is guaranteed to be highly energy efficient and in order to get that Energy Star rating, it must have a SEER rating of 14,5 minimum.

3°. The inverter technology.

The air conditioning low end model start their compressor when the temperature rise above a limit set by the user and stop when the desired temperature is reached. Those kind of units are using a lot of energy due to the compressor going from no activity to full load.

With the inverter technology, the compressor reaches full load and will then gradually reduce its speed until it has reached the desired temperature. The energy efficiency is something you really need to pay attention to, for the environment and for your wallet. It is mandatory to find a unit that use this technology.

4°. Air quality.

The experts tell us that you have to pay attention to the product that improve the quality of your air. Only a central system with HEPA or electronic filter is able to improve the quality of your air.

5°. Noise level.

It is also important to double check the noise level that your outdoor unit will create in order to respect your neighbors. It is commonly accepted that a unit with a noise level above 80 dBA is too noisy for you and your neighbors. Check the technical sheet of your machine to learn more about its noise level.

6°. Warranty.

The warranty is a good indicator of the quality of the unit you are buying. A good unit will have a lifespan of 12 to 15 years. Most of the manufacturer will offer warranties between 5 to 10 years on their units.


The installation need to be done by a contractor with a valid licence from the RBQ and CMMTQ.
