I have to commend the professional service of this company. I called upon CanaDuct to quote us on a large home with 5 furnaces. Paul, the lead technician, arrived punctually to offer a quote. As a rather congenial gentleman, we found his demeanor professional and easily developed a working relationship with him. He was very knowledgeable in this field and we accepted his quotation for the work due to his experience and the reputation of the company. On the day of service Paul arrived with 3 teams and 3 trucks, a home of 16,000 sq.ft. obviously requires precise coordination and effective choreography which was performed with ease. In addition, the company owner, Mr. Or Sela, personally service the 4 hot water tanks. The job was completed within about 6.5 hours. Paul also arranged our purchase of a variety of filters. He personally delivered them,then spent time with our family sharing his knowledge on their installation. The clear indication from this company is that customers are held in the highest regard. Our business relationship with Canaduct will continue and I have booked a return visit to our lovely home in about 6 months, to ensure that all is continuing well with our HVVAC systems. Our appreciation extends to all the technicians for a job well done, and of course, Lina for her very personable customer service. Great work! Bravo!
