We have central AC in the house but the 3rd floor got always hot with little relief from the central system. We discussed two options with Mario who came within 24 hours of our call and explained all pros and cons. In the end we had a Mitsubishi installed in the 3rd floor hallway. We paid a deposit (50%) on booking, the crew (Fabian and John) arrived as agreed, Fabian devised the best route for the electrical from the main floor el box and the best spots for the indoor and outdoor units. They covered the work area, worked diligently, caulked everything, cleaned, left us with manuals and documentation and explained how to operate the remote, etc. All staff we met or talked to were friendly and efficient. Nicole can sometimes get very busy but there is nothing that she could not handle and sort out. The price was perhaps not the lowest but the service was swift and excellent. We love to support local businesses in our area, and would recommend this company to anyone in the GTA without the slightest hesitation.
