I would like to take the time to compliment you on the helpful and knowledgeable staff you employ. I had a problem with a 21 year old Zenex central vacuum that a local repair man just wanted to ditch and replace. As someone who likes to breath life back into anything fixable, I was able to do just that with the very capable assistance from Danny. He was able (over the phone!) to walk me through repairing and cleaning the vacuum and getting it running again like new. Thank you, thank you, thank you!
