“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!
