Frequently Asked Questions
  1. Why do I need to have my air ducts cleaned?
    According to the EPA, indoor air can be up to 70 times more polluted than outdoor air. The benefits of a freshly cleaned air duct sytem include: (1) Cleaner, fresher and healthier air inside your home or office (2) Home and office furnishings will stay cleaner longer (3) Mechanical units will perform more efficiently when coils and blowers are cleaned which means energy and money savings for you.

  2. Will your equipment damage my air ducts?
    Absolutely not. While our equipment is designed to be aggressive at removing debris from your air system, it is also gentle enough so that it does not damage your air ducts.

  3. How much does it cost?
    For residential customers, the EPA says that "duct cleaning services typically - but not always - range in cost from $450 to $600 per heating and cooling system" depending on factors such as the level of service provided, the size and number of systems to be cleaned, climatic region and level of contamination, and the type of air duct material. For commercial customers, please call for a price quote.

  4. How will you clean my air ducts?
    There are two universally accepted methods to clean air ducts. One method is called contact cleaning, which stirs up and collects the debris at the point of contact inside the ducts. The other method is negative air cleaning or the "push-pull method". This method of air duct cleaning involves putting the air system under negative pressure, disturbing the debris inside the ducts and collecting it in one place.

  5. Is the process messy?
    Absolutely not. All of our vacuum equipment is HEPA-filtered to 99.97% so the dirt stays in the machine and out of your home. Our procedures are designed to protect your home and furnishings from dust/dirt and we always leave the home cleaner then when we arrived.

  6. How long does it take?
    It typically takes 2-4 hours per air system based on the cleaning method being used (residential customers).

  7. How often should my air ducts be cleaned?
    It is recommended to have your home's air system cleaned every 3-5 years. For commercial customers, we recommend a thorough cleaning every 2 years.
