The heating in my mom's house went down last month and I wasn't in Toronto at that time. I found Canada energy solution phone number and called them on Friday night, Jacky answered my call around 7pm and I explained the issues to him. The next morning David was at my mom's door ready to fix the heater. He told my family how to check up the issues like this. Excellent service 5 stars! Excellent work, professional and great attitude. Call Jacky if you need to repair or replace your air conditioner and heater. Thanks guys.
