Our experience with this company has been outstanding, beginning with the installation of our central vacuum system in 2002.
During the construction, I did some work wiring the audio system in the house, and needed an in-wall volume control. West Coast (WC) provided good technical assistance and mailed me a volume control that has filled the bill just fine. The part must have been mailed the same day I ordered it; it arrived very quickly.
Eighteen months ago, I needed some parts for a modification I was doing to the vacuum piping in our house. They were mailed very promptly, and at no charge!
Last month, I wanted to change the way our vacuum unit was vented, and stopped by the WC shop. An experienced installer sold me just the parts I needed, and cut the pipe to the lengths I requested, with no charge for all the assistance.
During this visit, we purchased several vacuum tools, one of which turned out to be defective. The WC person who answered my phone call cheerfully suggested that I mail the part back for replacement; we had our new tool in two days.
