I have been VERY impressed with the service I have received from both the sales/quoting people as well as the service teams at AT. They were all very respectful and super nice people. And the installation was flawless! The apartment is nice and warm now!

Excellent service from AT Climatisation. Their turnaround time was impressively fast, and scheduling was handled smoothly and professionally. What stood out most was their honesty and deep expertise—they clearly know their business and take pride in doing things right.

We recently had a new split air conditioning and heating system installed at one of our properties, and the service was truly exceptional from start to finish. The team was professional, punctual, knowledgeable, and extremely well organized. Their guidance throughout the process was amazing, with clear explanations, honest recommendations, and no exaggeration, just excellent service and quality work.

The gentleman who came to clean and fix my air conditioner was amazing. He’s really a gem. His name is Thomas and he cleaned up so well that the following day there was not an ounce of dust throughout the house. It was raining outside and he didn’t even bring any rain into my dining room as my air conditioner is off my dining room patio. He was incredible and I want to thank you Thomas for an excellent job.

We had a thermopump installed by AT Climatisation and the entire experience was excellent from start to finish. Communication was clear and consistent throughout, every question we had was answered promptly, and we always felt supported at each step of the process. Alex provided outstanding service, guiding us through everything with professionalism and attention to detail. The installation itself was handled by Samir and his team.

J'ai été TRÈS impressionné par la qualité du service que j'ai reçu, autant de la part de l'équipe des ventes et des soumissions que des techniciens d'AT Climatisation. Tous ont été très respectueux.

Le technicien, Manny, a été d'une aide précieuse. Il a pris le temps d'écouter le bruit provenant des conduits et a testé différentes solutions avec rigueur afin d'en trouver la cause.

Je viens de faire installer une unité de 36 000 BTU avec deux têtes murales. Le service a été exceptionnel ! L'installation a été rapide et l'équipe a même travaillé sous la pluie pour terminer le projet.
