The two technicians explained what they will do and didn't leave any mess. Show before and after work pictures to us. Also told us to check on some part that might need to be fix (which we can do it ourselves/ they didn't try to up sale or anything).
Gave great advices.

I was very happy with the service provided by Ottawa Duct Cleaning!
I received an email the day before the scheduled appointment detailing the preparation instructions. The team arrived on time and immediately introduced themselves and explained what they would be doing and answered my questions.
They laid down carpets in the house to protect the floors and they took pictures of the ducts and dryer vent before and after. They also told me when they were about to spray the ducts with the disinfectant.
They showed me the access points in the ducts that they created and how they were all properly sealed up at completion of the work and they explained that the same access points could be reused next time.
All in all a good experience. I wish all contractors operated this way.

They came highly recommended by my Furnace and A/C guy. Easy to deal with and high quality service. Our house is a complex vintage 1911 home with many additions and funky duct work added over the years. They clearly have experience dealing with the complex properties. Would definitely use them again.

I recently bought a 50 year old home and the ducts had not been cleaned in ages. The company workers were super polite. They reached into really hard to reach vents and cleaned them out super well. I am really happy with the service and will hire them again.

Exceptional service from Ottawa Duct Cleaning for the second time (after home renovations last year and this year). Great client service from Caroline (including quick e-mail communication and reminder of upcoming visit). Superb service from the duct cleaning team. Polite, answered questions, worked very fast, appeared to work well as team. Would not hesitate to recommend the team again.

Had my ducts cleaned recently by Ottawa Duct cleaners who did a fantastic job. They were at my door exactly as promised, the staff was very polite and the work was carried out quickly and professionally.
Very satisfied.

They got the job done.

Did not show us the before and after pictures of the main ducts as promised. Did not vacuum the dirt around the floor registers after cleaning the duct.

Not sure if they provided free odorless disinfectant as stated in their quote but I'll give them the benefit of doubt.

Average service to put in one word.

I hired this campany to cleaning the ducts of a home I rented for years, they were very proffesianl​ and made the home smell much better. I would recomond to anyone

They showed up on time. Were super polite and did a great job. They explained everything and left the place nice and tidy.

We'll be using them again and will tell our friends & family.

So happy with Ottawa Duct Cleaning. They e-mailed me the day before their arrival with how we needed to prepare. They went to my elderly parents' house and immediately introduced themselves with a smile and an outstretched hand as Jake and Spencer. They took pictures of the ducts beforehand and showed them to us as well as after. They said if we had any questions to feel free to ask. You got the impression that they weren't just paying lip service to the comment but rather that they really wanted you to ask them questions. They also said the company which we had used previously had done a good job; they didn't feel the need to put someone else down in order to elevate themselves. I've already recommended them to two other people. Superb job!
