After taking possession of a new home in early November 2018, there was a strange issue with the furnace. The heat would only be working periodically but all of the components and electronics were in working order. Fortunately Chris left his certification tag with his phone number on the furnace. Long story short, Chris solved the furnace issues very quickly and everything was covered under his warranty. I am very pleased with Chris from Viking Mechanical and would recommend them for anyone in Barrie or the surrounding area. Thank you Chris, you deserve and earned this five star review. - Rob from Hodgson Drive, Barrie.
