We can't say enough about the work ethic and the quality of work we received. The owner, Michael, and his assistant Kevin were very punctual arriving for the appointment. Both were very clean and wearing masks. Michael and Kevin walked around the house assessing the project for a few minutes. Then covered my floors and installed corner savers to ensure their equipment will not damage my walls. The job was performed with very minimal inconvenience and in less time than we thought. Once everything was done, Michael went through a few valid suggestions such as when and how to better use the duct covers as well as installing the UV light inside the furnace that will kill any internal bacteria for our further consideration. We really recommend this company to any home owner - big or small. Once you will all Sem's in your home and see the quality of work, you will never go with anyone else ever again. Thanks guys

I was really nervous about getting my ducts cleaned. I figured it was going to be a hassle and take all day. I was so wrong! Michail showed up and had everything done in just under two hours. He even cleaned the vents for me! I would recommend him to anyone who is looking for duct cleaning services in Toronto


Michael and his teammate were very professional and takes pride in their work. Did a good job in cleaning our ducts after renovation. His secretary was very kind and helpful too in squeezing us in for duct cleaning as they were fully booked. Thank you.

Post Renovation Duct Cleaning

I used the services of Sems Duct cleaning of Toronto last summer. My ventilation did not work well, the house was very hot and stuffy that summer. After they finished the work in my house, the ventilation began to work perfectly. It was cool in summer and warm in winter. I will use their duct cleaning services every couple of years!

I was really impressed with Sem's Duct Cleaning. I called them last week to get our ducts cleaned and they were out the next day. What I liked best about them is that they took the time to walk me through every step and made sure I was comfortable with everything they did.

I called Sem’s Duct Cleaning for duct cleaning and I must say that my confidence in using their service began from the first phone call. The phone staff were well informed and ran down the list of what they do before proceeding. From the equipment to the cleaning techniques, these guys were spot on and left my ducts spotless and super fresh. I highly recommend their services.


Sem's Duct Cleaning was amazing and very professional at helping us clean our ducts and vents. Mikhail was upfront with all cost and details of what is being done before the service started. He asked me to walk around with him so he can precisely show me what he is doing and suggestions for me as well. Kevin his assistance was also very friendly and professional himself. I would totally recommend Sem's to my family for duct cleaning, best service and quality. I am now guaranteed fresh air in my house for my family. Thank you Sem's Duct Cleaning for making this happen.

So great! Quick to return phone calls, showed up promptly. Sem's Duct cleaned our vents and dryer vent at laundry on Queen St E. Spent some time getting to the bottom of the issue. Now our dryer works wonderfully! 100% recommend.


Michael and his teammate were extremely friendly and impressively professional. They pulled in on time. Both properly uniformed, both polite and easy going. It took them 3.5 hours to be done with my 3500 square foot house, which was the quote I received over the phone at the time of booking. Now after the job I can see the difference: the air has a different smell and taste and it feels like I have just renovated the entire house – it’s that good. I'm extremely satisfied with the service provided by Sem's duct cleaning and I am especially charmed by the skills and professional approach Michael displayed while onsite.

Sem's duct cleaning went over and above what I asked for with their service. They were informative and friendly and gave me more than my money's worth. Definitely will use them again in the future and will recommend them to anyone looking for duct/furnace/carpet cleaning.

We just did a great renovation to our 3br house and before we moved in, we hired Sem's Duct Cleaning service to clean our ducts. It was such a pleasure to move in knowing that our kids will be in a healthy and clean environment. Once we need a duct cleaning service, I will call Sem's Duct Cleaning. Thanks.
