Selecting An Air Duct Cleaner

commercial duct cleaning services

There are many companies out there that promise to do a complete duct cleaning, unfortunately, many of them are all too happy to do a poor job and take your money.

Some methods do not remove contaminants at all, but instead, uses encapsulants to seal debris in place. Ductwork manufacturers and the U.S. Environmental Protection Agency (EPA) do not recommend use of this method. According to NADCA, the use of encapsulants can result in decreased energy efficiency, may void manufacturers warranties and reduce fire ratings, and may lead to health risks if encapsulants break down and contaminate indoor air. On the other hand, some companies claim to remove debris but use the wrong tools; one company even tries to use a leaf blower to clean ducts. This leaves you and your family vulnerable to the many irritants and allergens that this type of company leaves behind.

The most effective cleaning method uses high powered vacuum systems to remove debris from the ducts. As the vacuum works, mechanical devices loosen debris and the vacuum removes them from your system. There are a few other points to consider when choosing a duct cleaner as well. The National Air Duct Cleaners Association (NADCA) has compiled a list of these. These guidelines will help you narrow your search to only those companies that will provide you with quality service.

  • Is the company a member in good standing with the National Air Duct Cleaners Association (NADCA)?
  • Have they been in business long enough to have adequate experience?
  • Also, it may be helpful to check with your local Better Business Bureau.
  • Can they prove that they are properly licensed and adequately insured?
  • Are they certified by NADCA to perform HVAC system cleaning?
  • Avoid advertisements for “$99 whole house specials” and other sales gimmicks.
  • Ask if the company has the right equipment to perform cleaning efficiently and if the company has done work in homes similar to your?
  • It is wise to ask for some references from previous clients.
  • Review with them before hand what methods they will be using and make sure you are clear on all work and costs that will be involved
