I just had bought a house in Toronto which needed a major overhaul. Fully renovated the house from top to bottom so of course I needed a completely new and efficient heating, aircondintiong and water system. I contacted Eiden from Norther Air Control who came to my house within a few hours for a free estimate. Once he arrived he was very friendly and professional. He knew exactly what he was talking about and explained everything I needed to know thoroughly. He also suggested all the different equipment I could purchase, he gave me various options based off efficiency and price. He gave me his professional opinion based off the configuration of my house and I decided to go with what he suggested since he clearly had vast amount of knowledge. Once we decided on a date he showed up early with his crew, which were also very professional, friendly and clean. They finished the job within the day even though usually it takes more than 1 day. They did an immaculate job and i was more than impressed on how they excecuted what they set out to do. I will continue to call Northern Air control for yearly maintenances and for any future jobs I need or any jobs my friends or family need. Highly recommended for any heating, air conditioning or gas needs.
