Central vacuum installation: what to know

What the job involves, what changes the price, and what to ask a pro.

What central vacuum installation is

Central vacuum installation mounts a power unit in a garage or basement, runs tubing through the walls and floors to inlets in each room, and wires the control switch. It lets you vacuum with a hose and a light wand instead of hauling a machine. People book it when they build or remodel, or when they want a whole-house system that stays out of the living space.

Signs you need it

  • You are remodeling and open walls or floors where tubing can run
  • Your home has several rooms and carrying a vacuum between them is a constant chore
  • The garage or basement has space and a dedicated outlet for the power unit
  • You want inlets in each room, plus a wall switch that starts the unit
  • The house has a long run from the power unit to the far rooms
  • You want the exhaust to vent outside rather than into the garage or basement

What the pro does

  • Plan the power unit location, the tubing route and the inlet positions from the floor plan
  • Mount the power unit on a stable wall or shelf, and set the exhaust vent outside
  • Run the tubing through the walls and floors to each inlet, using sweeping fittings and avoiding sharp turns
  • Install the inlets and valves at the correct height, and seal the openings
  • Wire the control and the low-voltage switch, with the power connection made by a licensed electrician where one is required
  • Test the suction at every inlet and check for air leaks at each joint

What changes the price

Every job is different, so we do not publish prices. These are the things that move the quote up or down.

  • Number of inlets and the total tubing length
  • Whether the walls and floors are open, which makes the tubing run easier
  • Whether the tubing must be routed around framing, plumbing or ductwork
  • Power unit size and whether it needs a dedicated outlet added by a licensed electrician
  • Exhaust routing to the outside
  • Finished walls that need patching after the tubing is run

What a written quote should spell out

  • Power unit make, model and rated capacity, and where it will be mounted
  • Number and location of inlets, and the total tubing length
  • Which licensed electrician does the power connection, and the permit status
  • Exhaust routing, the wall or exterior vent, and the materials used
  • Warranty on the unit and on the installation, separately

Questions to ask before you hire

  • Where will the power unit go, and how will the exhaust reach the outside?
  • How many inlets does the plan include, and where are they placed?
  • Who makes the power connection, and is that person licensed?
  • Will you test suction at each inlet before you leave?
  • Do you use the tubing and fittings the system's maker recommends?
  • Will you patch and finish any walls or floors you open?
  • Does the warranty cover the unit and the installation?

Red flags

  • A power unit mounted in a room with no exhaust path to the outside
  • Tubing run with sharp bends that cut suction at the far inlets
  • Tubing left unsealed at the inlets or joints
  • A power connection made by someone with no electrical license when one is needed
  • No suction test at each inlet before the pro leaves

What you can do yourself

You can plan the layout, mark the inlet positions, and clear the garage or basement space for the power unit. Do not cut into walls or floors, run tubing, or make the power connection yourself. Call a pro for tubing runs, inlet installs, exhaust venting and any wiring.

Licenses and permits

Central vacuum installs that connect a new power outlet or wiring can need a licensed electrician, and a permit can apply to wall or floor openings and exterior venting. Check with your state or local licensing agency and your building department before you start.

Central vacuum installation questions

Can I add a central vacuum to an existing house?

Yes, in many homes, but it is harder than in new construction because the tubing must be routed through finished walls. A pro can tell you what the route needs and whether it fits your walls and floors.

Why does my central vacuum lose suction at one inlet?

A loss of suction at one inlet usually points to a kink, a blocked pipe, a loose joint or a sealing problem in the run to that inlet. A pro tests each run to find the leak.
