Duct Cleaning
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.

Frequently Asked Questions
Question: How often should I get my ductwork cleaned?
Answer: Frequency of cleaning depends on several factors, not the least of which is the preference of the homeowner. Some of the things that may lead a homeowner to consider more frequent cleaning include: The number of smokers in the household, any previous water contamination or damage to the home or HVAC system, pets that may shed high amounts of hair or dander, family members with allergies or asthma who might benefit from a reduction of indoor air pollutants, if any home renovations or remodeling has occurred, and finally; the cleanliness of prior occupants.
Question: How often do I need to change my furnace filter?
Answer: Check the documentation that came with your system. Recommendations vary based on a number of factors: the type of filter that you use, how many pets you have, whether anyone in your home has allergies, etc. If you use disposable fiberglass panel or electrostatic panel filters, you should change them anywhere from once a month to once every three months to a year. If you don’t change or clean your filter often enough the filter can get clogged with dust and other airborne particles, forcing your system to work harder to maintain airflow. This will reduce you unit’s efficiency and can cause damage.
