I called with Ali to check why my thermostst doesn't work anymore . It happened recently showing no power on my Nest thermistat. He came here my home on just time, and started to check my thermostat and moving down to check the furnice room. He found why the thermostat doesn't work exactly and explained to me. He was very gentle and kind. I recommend this company and Ali to my neighbour for repairing the Thermostat issues and Hvac issues.

Mr. Ali of 'Thermex heating & Air conditioning' is a thorough professional in his job and quite prompt in extending his services. Recently, on a very short notice, he came to our house and repaired the water heater in a timely manner. In addition, he also carried out a general inspection & provided valuable feedback on our HVAC system. Based on my observation and recent experience with Mr. Ali, I would recommend him for undertaking any such heating & cooling projects.

Ali did a great job installing our new furnace. He was professional, friendly, and very knowledgeable. Highly recommend his service!

I can't thank Ali enough! I contacted him today to assess/fix my AC that was leaking water, and he came later the evening and fixed it! And this is in the context of today's crazy rain/hail storm where his own basement was flooded, and yet he still came!

I would highly recommend Ali and his team. He replaced an Aprilaire built-in humidifier in my condominium. It was a complicated installation because the new humidifier was larger and had to fit into the same space as my old unit; as well some of the connections did not match my existing piping. Each and every time he encountered a problem, he found a solution. Although the installation took longer than expected, he honoured his cost quote. Originally when I asked ChatGPT to find me a heating and air condition company, Thermex was the first recommendation. I suspect this is because of his high ratings and customer satisfaction. I am pleased to be another recipient of his expertise and quality service.

Ali has helped us out twice now, once for a Senville Heat pump that needed charge, and a Mitsubishi mini split AC unit. He is amazing to deal with, prompt, courteous and professional. No-nonsense approach to the problems and executed the fix quickly and cost effectively. Highly recommended.
