Are central vacuums difficult to install?

Just as alarm installers or plumbers need training and certification, a professional vacuum installer should know building codes and pass the exams to work in his area. But the requirements are usually not onerous. Most people believe a central vacuum can only be installed during construction, and many vacuum retailers work with contractors to put in piping as the home is built. In fact, centrals can be installed in any home, anywhere and anytime. In Europe, where walls are solid concrete or masonry, our retailer/installers successfully retrofit Hayden systems. Piping is hidden from view and there is no trace of construction when the job is done. Retrofit installations are especially easy where walls are stud-and-drywall construction, as they are in North America, because piping is run through hollow, interior walls in the home. It is a simpler job than security companies have retrofitting existing homes by running wire through congested, insulated exterior walls.
