Ductless.ca installed a Mr.Slim in my Leaside home in 2010. What has really impressed me has been their follow-up service. We run our unit 24/7 so it has needed some maintenance over the years. One call/email to Ductless and they have always been there to take care of the problem at a fair price. Even during a recent heat wave when I'm sure they were swamped, they found time to order a part for me. The founder/owner is a gentleman as is his son, a P.Eng now with the business.
