Sub Zero Technical Ltd

I've used SubZero for several jobs on properties over the years, they are the only ones I will call. I appreciate the honest advise, education and explaining the different options to choose from; they were not just trying to sell me the most expensive product or up sell me. Great customer service to top it off. Highly Recommended!

We had a garage heater installed today. As per usual the guys were prompt, courteous and did a great job! Subzero has installed our air conditioning and did a new furnace and hot water heater last winter! Great people to work with!

The technicians from Sub Zero arrived on time and ready to do the job. They were very pleasant to be around, and clearly loved what they do. A bonus in any job. They took the time to explain things to me, when I went to ask. They worked hard all day, and into the evening to get the job done properly. And, they cleaned up after the job was complete.

I have been using this Company for 4 years and have been CONSTANTLY impressed by the Quality of the Work and the Quality of the technicians that they send here. Jeff especially went out of his way ON HIS DAY OFF ON THE WEEKEND and came and completed some work that needed to be done so I would be able to have heat during a snow storm. Thank you to everyone at Sub Zero I wish you the best always.

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.

Jeff was knowledgeable and helped me understand the issue with my A/C and how to prevent issues in the future. Got it up and running the same day, thankfully, as it is so hot out! Thanks so much!

Subzero crew were on site on schedule. First day the high efficiency furnace, thermostat and high efficiency hot water tank were installed and operational by the end of the day. Second day the A/C was installed and also operational by the end of the day. All systems and workmanship completely met my expectations. Having used Subzero commercially for many years I knew they were the only company I could trust with this complete home mechanical installation. Tyler insured all workers respected Covid19 safety, and my home inside and outside were left clean both days. I highly recommend you consider Subzero for your home heating, AC, water heating needs.

Jeff at Sub Zero was very kind to help me over the phone before having to send out a technician. Proves there are still nice people and honest companies in this world. Will definitely contact them first when I actually do need a professional.

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.
