Just had a new 5 stage R/O system installed under our kitchen sink. Our old one was leaking and American Home Water & Air was able to come out same day. Angle was the installer. He was on time and quick. He was very polite and courteous. He even mounted the system to the side of the cabinet so I gained storage space under my sink. 17 years of having an R/O system under my sink and no other technician has even asked if I wanted it mounted. I appreciated the extra effort Angel made.
