Excellent knowledge of all vacuums they sell and support. Went in to purchase a hose that was torn on our Dyson, (*(8) year old Dyson NOT purchased at AceVacuums). They immediately took the time to order the hose and then install the hose for us>. Impressive. We then looked at their line of Vacuums and were impressed with the knowledge and professionalism of the Manager Member Chris Engle, that we purchased a Riccar Vacuum. They know their stuff, polite, professional, and customer service oriented.
