Maintenance is key to extending the lifespan of a central vacuum - you should run a knife over the bristles occasionally to make sure nothing is caught up in them. You should also change the paper liners every few months and cloth liners every 5-7 years.
Wow what an experience!! Doorbell simply doesn’t work. Motion sensor goes off every five minutes. Called them many times and I keep getting ignored. Only time I got their full attention when they wanted to bill me....
Javid was wonderful to work with, patient in responding to my inquires about different models, flexible with scheduling the installation to convenient times for me. I would recommend him to anyone.
Thanks for your help!
