Jan, the Better Business Bureau in Houston has a directory of BBB Accredited Businesses at the following link. Just search for air duct cleaning companies and you should find several. http://www.bbb.org/houston/directory/greater-houston-accredited-business-directory/1/

Can you tell me how to find a reputable air duct cleaning company in the Houston, TX area?

Last year my wife had a stem cell transplant as she has amyloidosis. We wanted to ensure the ducts were clean as it's common to develop allergies and the like after a stem cell transplant. The company (shall remain nameless here) sent a team out and they pulled down the grill from the return vent for the HVAC system. When we installed the HVAC system we'd painted the return area black so that when you look up to the ceiling all you see behind the grill is black (rather than rough construction, 2x4's, drywall, etc.). The scamster sees the black and proclaims, "you have black mold!". I told him that was absurd so he said he'd go get his test equipment. I'd had prior experience creating a semi-clean room used in the creation + production of electronic sensors and recalled that our "clean-room" wasn't even clean enough to avoid detection of microscopic spores. And, sure enough, when the scamster came back in with his "test" equipment, it rang up and he wanted $500 or more to "fix" the problem. I told them that we'd report them to the state AG and file criminal complaints with local PD because the scamster took my coupon with him (I considered fraud + theft) The company took my threats seriously and had a different team return and - while not admitting anything - performed all the work for NO CHARGE. -- Steve
