“After asking local Oshawa folks online who they recommend for AC install, Comfort Masters was the top answer. I had a great experience from scheduling to sales but what made the experience great was the install by Taylor! He took all the time needed to walk me through the install and talk about options and to do the job right. He was respectful and tidy as well. Thanks for making this large install a breeze!

“Comfort Masters installed air conditioning and heating systems in my home on August 12, 2020. I would like to thank Dan and Ryan for their professional expertise, very respectful and on time. They had explained how the systems worked and gave me a tutorial on how to work the controls, they were very patient and took the time to make sure I understood the devices before they left. Also, they made sure the outside of my house and in was clean and debris was removed. Thank you. Great service.
