Indoor air pollution can actually be worse for you that outdoor pollution!

Carbon Monoxide Detection

Carbon Monoxide is a dangerous gas that you can’t see, smell or taste, and can build up in enclosed spaces in your home. Our well-trained technicians know how to test and where to look for possible leaks and faulty equipment that can be contaminating your home and family with this deadly poisonous gas.

Duct Cleaning

Does someone in your home experience allergies, asthma or respiratory disorders, headaches, nasal congestion or sinus problems? Both Total Health and Better Health magazines cite that “1 of 6 people who suffer from all allergies do so because of the direct relationship to fungi and bacteria in the air duct system.” Simply put: dirty ducts can make you sick. The Department of Consumer Affairs adds that “children and elderly are especially affected by polluted indoor air.”

Items that get trapped inside your duct and create a breeding ground for bacterial are:

  • Dirt
  • Pollen
  • Smoke
  • Pet Hair
  • Dust mites
  • Even dead skin


Every time you turn on your system; these contaminants get blown into the air that you and your family breathe.

Our special cleaning processes have been approved by the NADCA (National Air Duct Cleaners Association).

How does our system work?

Our "source removal" cleaning method uses a powerful, specialized vacuum to place the system under negative pressure. While the vacuum draws air through the system, specially engineered brushes are inserted into the ducts to dislodge any debris that might be stuck to interior surfaces. The debris can then travel down the ducts to the vacuum, which removes it from the system and the home.
