Iain Martin

I’ve been calling Henry for the last 4 or 5 years for commercial and Residential HVAC work. He’s always been very thorough and isn’t happy until he’s 100% sure he’s finished the job or found the problem. I’ve happily recommended him to multiple family members and friends and have never been concerned that they wouldn't receive anything but the best service from him. I’m not looking forward to the day he decides to retire and I have to find another HVAC technician.

Jennifer MacDonald

H2 HVAC came to us when we were in an urgent situation. We needed our furnace repaired ASAP and they were able to service our unit in less than 24 hours. Henry was prompt, professional and courteous. He was extremely knowledgeable and walked us through every step of the process. I would recommend him and his company whole-heartedly.
