Shaun arrived on time and was courteous. He seemed to be very knowledgeable and took the time to explain the repair that was needed. We appreciated his attention to detail. It was a pleasure to meet him.

Very professional, patient, polite and precise. From inspect and quote to install, everyone was great, especially Shaun and Jordan! Answered all of my (many) questions. They made sure I was happy. Highly recommend!

Excellent service!!!

I selected ATS Mechanical to install the new AC and heating system due to their high standards. Barry came over and laid out many options for me to choose from and was never pushy as to which option I should choose. He gives you the facts and allows you to make the right decision for you and your financial situation. The technicians were very professional and got everything installed and working within a day despite the cluttered nature of the attic that they would be working in. I am very pleased with the outcome and look forward to the savings that will be coming on my monthly energy bills!

Good job. Shaun updated my vent system and it works good.
