What Customers Say

“Just had a duct cleaning and furnace installation. Amazing difference from the cleaning, and can’t wait to try out my furnace this winter, which thanks to M&K’s honesty, is now the proper size for my house (previous one was too big!)”

Frequently Asked Questions

When you get your ducts cleaned, you remove particles and contaminants circulating your house. Dust, debris, and even mold can build up in your ducts, so getting them cleaned can eliminate the amount of bacteria that travel around your home. Reducing these contaminants means creating cleaner air, reducing allergy symptoms, and can even eliminate odour.

Without regular cleaning, your ducts can build up contaminants that then travel through the air in your home. Getting your ducts cleaned at least every 5 years can significantly reduce the amount of bacteria in your home.

Depending on how big your home is, duct cleaning can take between 4 to 6 hours. The larger the house, the larger the duct system, which means the more tie needed to clean it. Additionally, if it’s been a while since you’ve gotten your ducts cleaned, more debris may need to be removed, which may also take longer.

As with the length of time needed to clean your duct system, how much it costs largely depends on how big your duct system is. Bigger houses with more significant duct systems will cost more to clean, but they usually stay around the $600 mark.

Although you don’t need to be home for the entirety of the cleaning, if you are home, we can notify you immediately if we find any issues with your system. For potentially dangerous things, like mold and asbestos, we want to inform you as soon as possible.
