Impeccable service. Forty-eight hours after receiving a quote, the system was installed and working (and performing very well). Thanks to your team of technicians who worked tirelessly in the extreme heat, I am impressed. I recommend this company; they are responsive and dynamic, and they go the extra mile for the customer experience. All this in a difficult context (heat wave + pandemic). If they are this proficient in customer service, they deserve more than 5 stars! Thank you again for your excellent service.

Prompt replies and excellent service. We had left messages with several companies and George responded the most quickly. The evaluation, the quote, the scheduling of the installation, everything went well, within the time frame promised, even though the workload was very high. We recommend AT Climatisation.

Very good service, I called ten locations during the Montréal heat wave and all locations had one-month delays. AT Climatisation took the time out of their busy schedule to install the unit the day after my call! Very happy with the product!

From the service call to the moment Houssem, our repairman, left, the service was outstanding! I recommend! 👍🏻

From the time I called for information, to the installation, and then to my first attempt at turning on the system alone, everything was perfect. Very well informed, the entire process was quick and simple. Thank you to the entire team, professionals who are also very friendly and attentive—despite my thousands of questions! With my Air Tempo, summer can come, I’m cool!
