Toronto Heating and Air Conditioning Expert

I have a Navien hot water heater that controls my radiator heating system and hot water. The water stopped working during the Christmas holidays. I called Robert from Cozy Castle and he came right away and diagnosed the problem. He had to order a part which took a day to deliver. Robert returned the following day (a Saturday during the holidays!)and repaired the unit. He even went up into my roof to ensure the exhaust was venting correctly. He was very thorough and priced the repair very fairly. I would not hesitate to hire Cozy Castle.

Rob and team did an amazing job installing a Navien tankless water heater to our home. He’s super efficient, clean and organized. Totally recommend him.

We had Cozy Castle walk us through the entire heat pump process, as well as a number of similar companies. We went with them because they seemed better informed and more realistic and honest with the information they were relaying. And we are quite glad that we did. The team were great to work with, they had everything working well and seamlessly. The price was right, it didn’t change, and they’ve been responsive to any follow-up questions we’ve had. if you are interested in a heat pump, or similar work, I would highly recommend Cozy Castle.

Cozy Castle exceeded my expectations with my Heat Pump purchase. Rob was a treasure trove of technical knowledge and went the extra mile to ensure I was informed about the process and options. The installation team was meticulous, taking the necessary time to ensure the job was done right, showcasing their professionalism. Cozy Castle’s dedication to customer satisfaction and high standards make them a standout choice. Highly recommended!

I simply cannot say enough about Rob & Cozy Castle. I met Rob 2 years ago when my old Navien Tankless Water Heater started leaking & he managed to get me a new Heat Exchanger from Navien under a little known warranty, so the expensive part was free! Yesterday, my A/C stopped cooling so I called Rob in the afternoon & he drove all the way to Newmarket the same day & had it fixed by 6:00! Ridiculous service!! Oh & the last & most important item – Rob is extremely honest + will save $$ whenever he can & certainly doesn’t overcharge for his amazing work. 6 STARS!!!

I was hesitant to hire services of a company that was recommended through Facebook rather than personal recommendations and experiences. None of my friends however has recently installed a humidifier and so nobody I knew could recommend a technician. The staff technician of this company not only installed a humidifier, but he also made recommendations about the heat pump that was installed by another company just two weeks ago. I then reached out to that company and pointed out on mistakes they made. They agreed to fix their mistakes. So, it was a dual service that Robert (our licensed technician) provided without charging any extra. I highly recommend this company.

Great service and priced as advertised. Nice to deal with an honest company. We will do our business from now on with Cozy Castle.

Excellent service. Owner took his time explaining all options available. Technicians were knowledgeable and clean worker.

I reached out to Robert and team at Cozy Castle because I needed a new a/c unit. Within an hour or 2 he was at my house for an estimate on a Friday afternoon. We scheduled the installation for Monday and although it was raining heavily in the morning his crew showed up once the rain let up a little (they still worked in the rain). By late afternoon my new unit was installed, the old was was taken away. The communication through out was excellent and over all very happy with the process from beginning to end. Highly recommended.
