Questions about replacement and upgrades

Can I replace the power unit and keep the tubing?

Often, yes. We check the tubing for leaks and blockages and confirm compatibility with the replacement equipment. Inlets, wiring, hoses, and attachments also need to be checked.

Can you modernize an older central vacuum?

We service and upgrade older systems, including Filtex, Black & Decker, Sears, and Kenmore. Some original parts are no longer available. We’ll check your system and explain which repairs or replacement components are possible.

Can you add an inlet to my existing central vacuum?

Yes. We can add inlet valves to an existing central vacuum system. Call us to discuss where you need one.
