Mckinnon is an indoor air quality comfort company providing comprehensive services and products to Toronto home owners and small businesses since 1934. “In a word – FABULOUS. Michael Nepom and his team at Mckinnon were efficient, punctual, polite and came in on time and on budget. (…) This was the second time I have used Mckinnon and I would not hesitate to recommend them. You can do no better!”
