We recently got a furnace upgrade done by Heatmaster Services and were blown away by the fantastic service we received. Dmitri was very pleasant to deal with as well as informative. He gave us awesome tips on how to increase our energy efficiency and keep our furnace in good working order for years to come. I have been highly recommending Heatmaster to my family and friends ever since. I'm not one to write reviews but his exceptional service prompted me to share my experience.
