I called the company and John answered. We set a time for him to come over that was convenient for us both. He came exactly on time and went right to work. He removed all of the vent covers, including some screens that were over the vents that I had no idea were there. He washed all of the vent covers with soap and water and then started to vacuum all of the ducts, doing a complete and thorough job. He was extremely friendly, professional and worked quickly and thoroughly. He even checked the dryer vent exhaust on the roof to make sure it was clear. After he finished vacuuming the ducts, he sanitized them and then reattached all of the vents.
They arrived within the time range I was given, and they even called about 20-30 minutes before arrival, so that was appreciated. They arrived and started bringing some equipment - A shop vac (yea, like you can buy at any hardware store), a handheld vacuum cleaner, and large vacuum that came in on wheels. After showing them the locations of all of the vents in the home and cold air returns, the technician (Simon) started going over a few things with me about their plan for cleaning and showing me the dust & dog hair build up in one of the vents. After showing me that, he started to try to up-sell me on additional services. That additional service was to insert a 'brush' that would agitate the dust/pet hair and allow for the vacuum to get everything out of the vents.
Be cautious with companies that offer “whole house air duct cleaning,” urges the NADCA. The company may be using unscrupulous tactics to upsell you once they get started. Before any work begins, always clarify in writing what the job entails and what the cost will be. To protect yourself against fraud, read customer reviews and verify that your HVAC cleaning service has applicable licenses and certifications.
Interestingly, I had this service performed several years ago, by a cheaper company. Based on the amount of dirt and junk that was removed yesterday, I now have my doubts that the previous company really performed the work. Yes, I checked this time! The owner, John, told me that there is another company working under the same name, so make sure that you are getting the Arizona Air Duct Cleaning Company, father and son team, that is being reviewed here. Not all these companies are honest and do what they claim to!
You should be aware that although a substance may look like mold, a positive determination of whether it is mold or not can be made only by an expert and may require laboratory analysis for final confirmation. For about $50, some microbiology laboratories can tell you whether a sample sent to them on a clear strip of sticky household tape is mold or simply a substance that resembles it.
