I don't recommend this place. When I had my vacuum being serviced, he sold me a "universal" part for my vacuum stating it fits all types; however it didn't fit and when I took it back he refused to refund my $. Not reliable & deceptive.
Great service from Dr. Vacuum... first time, they installed a vacuum exhaust pipe for my central vacuum. Second call, they told me how to clean my inner filter, and thereby saved me the 75$ service call charge. Awesome. I will never need to call anyone else.
