Frequently Asked Questions

Many homeowners never think about their air ducts, but they play a crucial role in maintaining a clean and healthy home. Over time, dust and other debris can build up in your air ducts, leading to poor indoor air quality and an unpleasant smell inside your home. Regular residential air duct cleaning your air ducts can help remove this build-up and improve the scent of your Toronto home.

How often you need to clean your HVAC system depends on the type of system you have and the environment in which it operates. If you live in an area with a lot of dust, pollen, or other airborne particles, you’ll need to clean your system more often. The same is true if you have pets that shed as their hair can clog the filters and reduce the efficiency of your system.

Depending on the type of HVAC you have, you should plan on having a residential AC duct cleaning every one to three years. Not only does this ensure that your home is comfortable year-round, but it also helps keep your energy bills in check. A well-maintained HVAC system doesn’t have to work as hard to maintain the temperature you want, so it uses less energy and saves you money.

If you’re wondering whether or not your air ducts have been effectively cleaned, there are a few things you can look for:

  • Look for visible debris: After the cleaning, take a look inside your air ducts. If you see any dust or debris, then the cleaning wasn’t effective.
  • Check for airflow: Another way to tell if your air ducts are truly clean is by checking the airflow coming from your vents. If it’s weaker than usual, that’s a sign that there’s still debris build-up in your ducts.
  • Get an inspection: The best way to know for sure if your air ducts are clean is to have them inspected by a professional. They will be able to tell you definitively if the job was done right.

Our technicians take extra steps when conducting your AC duct cleaning in Toronto. Once it’s completed, we’ll perform a thorough inspection to ensure there isn’t any leftover dust or debris in the vents.
