I purchased a filter queen vacuum from duffys in the past. It's a great vacuum and I have been quite hard on it, so it recently needed some repairs. I brought it to the shop and Jamie did a great job fixing it and had it back to me with in a day!! He was a very knowledgeable mam and answered all my question about central vacuums! I will continue to use their services and purchase a new vacuum or central vac in the future!
