Toronto Residential Air Duct Cleaning _ How We Work

What our process for residential & commercial duct cleaning includes


Our experienced operator will first shut down your air handling unit and allow our technicians to get into your home or office duct system for cleaning.


Our crew will cover all the floors to avoid any damage and place corner protectors to further eliminate any potential for unwanted occurrences.


Once your property is safe and secure, our technicians bring in a large vacuum hose and place one end into your fireplace.


Once one section of the 10” hose is in place, our team will position the other end into one of your distant air vents and begin our cleaning process.


They’ll dust the vents using compressed air at a pressure of 230 – 250 PSIs and ensure your ducts receive a treatment that won’t damage them.


From there, our crew will supplement their efforts with an air snake and air pipe to ensure your ducts and vents are thoroughly washed out.


Once your ducts and vents are clean, our technicians will move on to other parts of your system and clean them together with the coils and other parts.


Once your ducts, vents, and system are completely clean and free from dust, dirt, grime, bacteria, and other contaminants, our team disconnects the hose.


If our team had to create any additional entry points to your system, they’ll seal them and run your system for a cycle to see if it works properly.


Finally, our technicians will happily take care of any additional specific requests you might have to give you a service you’ll be satisfied with.

Once our team of skilled, qualified, and experienced technicians is done, our clients experience an immediate improvement in air quality in their property and the efficiency and performance of their heating and air conditioning unit. If you’d like to breathe cleaner air, reach out to our company today and receive a $50 discount on any service ranging from $400 and more.

Michael is the owner and takes great pride in his work. Kevin has been two years with Michael and also was very friendly and helpful. They were very careful when they had to move furniture to access all the points they needed.
