High Velocity Systems

“In a word – FABULOUS. Michael Nepom and his team at Mckinnon were efficient, punctual, polite and came in on time and on budget. (…) This was the second time I have used Mckinnon and I would not hesitate to recommend them. You can do no better!”

Liam Romalis | Toronto

Great job on our new ductless air conditioner. The installers were knowledgeable, helpful and worked to meet our expectations.

We will happily recommend Mckinnon will also use them for our furnace going forward.”

Paul | Etobicoke

A quick note to say what a tremendous twosome you had installing our new hot water system today. Two very competent, polite, professional installers who used such care in the entire installation process. (…) We appreciated the fact that these people were willing to do this work on this very busy Xmas eve.

Marie and Tony G. | Markham
