Hi,
I was speaking with a friend today. He's very familiar wth the vacuum industry and cited many issues -- inexperiencce, bad repair jobs, even possible sabotage for gain. -- as good call for licensed vacuum repair persons. I'd think especially so for high-end, or do I just mean high-priced, vacuums.
A good point being that if you can't install a high-voltage central vac without using a trained electrician why should the consumer have to put faith in the undocumented training of a repair establishment's personnel. Vacuum repairs after warranty end are getting pricey.
What do you think? Send the vac to someone who claims to have the knack OR to someone who has credentials?
