Air Duct Cleaning

Air Duct Cleaning

Did you know your air duct system could be contaminated with particulates that can be harmful to you and your family's health? Dirt and dust, dust mites, pet hair and dander and rodent feces are just a few things that can be inside your air ducts and circulating through your home in the air you breathe. With our state of the art video inspection system, we can show you deep inside your ducts to see if cleaning would be beneficial for you!

Indoor air quality facts:

  • The EPA has ranked indoor air quality as one of the top 5 environmental risks to public health.
  • More than 50 million Americans suffer from allergies. According to Total Health and
  • Better Health magazine, 1 out of 4 people who suffer from allergies, do so, due to the fungi and bacteria in the air duct system.
    Indoor air is 2-5 times worse than outdoor air.

Dryer Vent Cleaning

Dryer Vent Cleaning

Just like your air ducts, you can’t see inside your dryer vent! Using our video inspection camera, we are able to show you all of the dirt and lint that stays inside your dryer and vent once you have completed your laundry and cleared the lint trap. By cleaning your dryer vent, we can help ensure your clothes dryer is both safe and energy efficient!

Dryer Vent Cleaning Facts:

  • A study performed by the U.S. Fire Administration in 2012 showed, “Failure to Clean” was the leading factor contributing to the ignition of clothes dryer fires in residential buildings.
  • 84% of clothes dryer fires occurred in residential buildings- source NFIRS, National Fire Incident Reporting System
