I used “Imperial Energy” services for my new house in North York, Toronto. They have installed two new furnaces & two new air conditioners (also one of each my old ones) plus the duct work & gas lines. Overall their performance had so many flaws (Enbridge inspection took many visits to pass) & their subtrades were not efficient, missing duct closing (causing foam insulation into ducts- picture), wrong frame-opening for typical wall grills (causing redoing the drywalls - picture), installing the HRV unit at head-height (there is room above - picture), caulking & patching the holes through the walls were never done. They have a contract like car dealership’s (small writing in pages), also they have a collection agency set up for their contracts. So many things were extra during construction at their own nonnegotiable rates, and my job’s completion was hostage for the payments. I felt they are more developed & organized in how to get more money in shortest way than providing decent service.
