Excellent service. Completely satisfied. I will not go for anyone again looking for somebody to do my duct cleaning.

Our technician, Darwyn, arrived promptly as scheduled…worked very hard and consistently for the duration he was in our home … and seemed to be making every effort to do a thorough and diligent job.

After long renovation on my house, I called National Duct for cleaning my ducts. Ahmad was the service technician, he was very efficient and professional. He walked through the whole process with me. He explained carefully and showed me all the pictures before and after of the return and supply ducts. My house is now dust free comparing to few ago. Thank you Ahmad for doing a good jobs. I highly recommend National Duct.

Jarran arrived ahead of time. He was professional and did a wonderful job with our ducts. I would highly recommend using National Duct Toronto

We had a great experience with National Duct Toronto. The previous owners of our home had some some renos that weren't properly cleaned (drywall bits in vents etc.). It took them twice the amount of time to clean our ducts and there was no extra charge for this. The technician arrived on time and was friendly.

So glad we went with National Duct. Warren was extremely thorough and they were quite reasonable. I would highly recommend them.

We wanted our furnace ducts cleaned as it had been awhile (10) years So glad we did. Was it dirty! Russ was helpful with any questions we had and did the job in the timely manner he said it would take. He also showed us before and after photos. Thanks again for the great job! Will highly recommend! Roxanne

Very respectful and a thorough job was done. Price was very reasonable. Highly recommend the company.

We recently had our ducts/vents cleaned, and I’m really pleased with the work completed. Ahmad, the service technician, did an excellent job. He was professional, polite, and efficient from start to finish. He took the time to explain the process, pointed out areas that needed extra attention, and made sure everything was cleaned thoroughly. I appreciated his attention to detail and the care he took while working in our home. It’s already made a noticeable difference in the air quality. Overall, a great experience. I recommend this company to anyone looking for reliable duct cleaning services.

We googled local duct cleaning and called National. We received an immediate quote over the phone. Ahmed was our service technician. Very professional and efficient. He explained all aspects of the work to be done. It was refreshing to work with company and a technician that puts the customer first and understands customer service. Ahmed is an honest man who shows integrity and pride in the work he performs. We were very satisfied with the work and the price. We highly recommend National Duct Hamilton.
