Updated review from a week ago regarding bad experience with a new tech; it went from 1 star to now 5 STARS!!! After providing my feedback, the owner David contacted me to make it right. I agree, we are not perfect and we do deserve a 2nd chance. This exactly what the owner did, offered to make it right and they sure did! It was a pleasant 2nd experience where everything went well, the tech was professional, clean, and on top of things! This is what a good business is about; reaching out to make sure we as customers are satisfied and if not, do all possible to accomplish that goal. Nowadays is hard to find a company like AZ Air Cleaners and specially an owner that truly cares about his customers' satisfaction; thank you David! You really made an impression and good statement. I will definitely recommend them as they do stand behind their name and go above and beyond to make sure their customers are satisfied! That is remarkable! Now I understand why this company is highly rated and if someone has written a bad review, they need to talk to them and give them a 2nd opportunity to make it right. We all try and hope we provide an excellent first impression, but many times is not possible or out of our hands to do so. After all, very happy with AZ Air Cleaners!
