"This review is about Air Duct Professionals and I want you to know that I finally found a company that was honest and professional. Because when I was at the end of my wits trying to figure out who was telling me the truth, I called Ed Mack the owner and he was reassuring that my home was not that old to be having all these problems. He referred me to a website for the Air Duct Cleaners Association and read about what air duct cleaning really does. So I had Air Duct Professionals come out to the inspection and they have an actual HVAC guy on their staff. Immediately looking at how new and well maintained our air system was in the attic, he told us those other companies were trying to scam us. Air Duct Professionals did a great job cleaning out all of our air ducts and dryer vent and cleaning up after themselves. I whole-heartedly recommend this company for their professional work and honesty."

"My HVAC unit stopped producing heat so I called the folks at around the clock. They offered to come out the same day and after taking a look up on our roof determined it was a faulty control board. We talked a little about the lifespan of the unit and that while it was probably going to need to be replaced in the next 5 years or so, it made more sense to simply replace the board today. So he scheduled an appointment for the following day to come back with the replacement board. 1 day later and 15 minutes of work and I have heat again."
