What Our Clients Say

5 Star Review

We lost our heat when the polar vortex hit last week. We called Sub Zero on Sat at 7:30 am & Robert was here within 1/2 hr. He not only diagnosed the problem but spent 15 minutes on the roof at -34 & cleared the ice from the vent - clearly above & beyond the call of duty. I have been their customer for over 20 years & found their reliability, technical expertize & customer service to consistently be great! Last week’s experience just proved it! I highly recommend them.

5 Star Review

I am so impressed with this company!! Jeff and Robert did an excellent job of installing our new AC system. They were here on schedule and kept us appraised of their progress throughout the day. They both went beyond what we were expecting, making the necessary changes to our existing heating system to ensure optimal efficiency of the AC system. Even though we had a couple of issues based on the existing heating system, Jeff was able to troubleshoot and overcome the issue. They both ensured that clean up was thorough and all waste was taken with them. The next day, Jeff followed up with a phone call to ensure that the system was still working properly. Both Jeff and Robert were very professional and their work was very high quality. I highly recommend Jeff and Robert and Sub Zero to look after all HVAC needs.

5 Star Review

Some months back had a new central AC system installed by Sub Zero Technical at my house. Their manager Ross provided a sensible quote with a proper breakdown of the proposed cost, based on a free home visit. Their qualified technicians - Robert, electrical; Tyler, air-conditioning - accomplished the AC system installation work in an (to the extent I as a layperson in this field could determine) overall competent and professional manner. I was very impressed by their positive demeanour and apparent technical expertise, and feel lucky to have come across Sub Zero for this work. I feel real pleasure in recommending Sub Zero Technical for any HVAC work of the type they list on their website (do check it out). My sincere thanks to Sub Zero, specifically to Ross, Robert and Tyler. Remain very appreciative.
