I used Angie's List to find HVAC air duct cleaner near me. Arizona Vent Cleaners was one of many businesses that responded. I made an appointment to have my air ducts cleaned. On September 11, 2021, Arizona Vent Cleaners came to my mobile home to clean my ducts and remove the mold. The mold is still visible and the smell is worse than before. I contacted the owner of Arizona Vent Cleaners, Del Glenn, the following day to inform him that the mold was still visible and the odor was worse. He said his tech would be in Tucson September 16, 2021 and would do a follow-up service between 12 pm and 5 pm. The technician never showed. I've been trying to contact Mr. Glenn to let him know that his worker never showed. I left a phone message regarding this fact. I have yet to hear from Mr. Del Glenn or his tech.
