Kiwivac Can Service and Repair All Brands Of Central Vacuum Systems

Central Vacuums for Renovations

We can install a Central Vacuum System in 99% of existing homes. Regardless of whether you plan to remove wallboards or leave them intact, we can install a vacuum system for you.

Leaving Existing Walls Intact

In this situation we bring the pipes down through the back of cupboards and wardrobes, so the entry point is hidden. They connect to a power unit that is typically located in the garage. 

However if your garage is not attached to your home it can be hung in a cupboard as long as there is adequate ventilation. Or the power unit can be installed under your home, in the basement.

Then we install inlets in the wall, usually in the hallway and living room.

Removing Existing Wallboard

While the studs and nogs are exposed, before putting up a new wallboard, we bring the pipes down inside the wall cavity, through the nogs just like when installing into a new home.

These get connected up with the rest of the pipework either in the ceiling or under the floor.


This part of the installation is like installing a system into a new home. We come in when the roof is on and before the insulation is put in and the wall board goes on. Which is around the same time as the electrician and plumber.

We bring the pipes down inside the wall, through the nogs just like when installing into a new home. These get connected up with the rest of the pipework either in the ceiling or under the floor.

Our New Zealand wide network of Kiwivac AVT experts have installed over 15,000 systems and are trained to:

  • Design your system to perform at its best at all times
  • Design your system to be user friendly
  • Consult with you on the best design, hose length and tools for your needs
  • Carry out the installation to the highest standards
  • Ensure your installation is New Zealand Building Code compliant


Planning your system is the first step. The method we follow will depend on whether you are leaving existing walls intact, or removing them. We will figure out the best location for pipes and inlets.

Pipes are run within the walls, either up into the ceiling or under the floor. Multi-storey homes are done the same way, with the pipes going between the different levels.

Around your home, you will find inlets covering an area of about 60 – 100 square meters.



Then we design a solution that is:

  1. User-friendly and adaptable to the layout of your home
  2. Efficient, so you get maximum performance for the size of your home
  3. Perfectly suited to your needs. So that we can tailor a solution to your preferences, we ask questions like:

    a) Would you prefer bagged or bagless?
    b) What’s your ideal hose length?
    C) What type of accessories do you want?
    d) How about a retractable ‘hide-a-hose’?
    e) Do you require a Vacpan in your kitchen?



Experienced installers will ensure your Central Vacuum Cleaner complies with building codes. For existing homes we can install your new system at a time that is convenient to you. 

The installation is done in two parts (for new builds)

1) The pipe work is installed in the walls at the same time as the electrician and plumber, when the roof is on but before the insulation and wall boards are put up.

2) Finishing the system off – we come in and hang the power unit (vacuum unit generally in the garage), install the wall inlets face plates/cover and supply the hose and accessories when the house is painted and the carpet/floor coverings are laid.

If you already have a central vac system and are living in your home while renovating we can make it so you existing system can still be used while the renovation/extension is under way.



Once the system is installed we will show you how to use it, including how to change the bags or empty the bin.

Designing Your Central Vacuum System

Accessories & Colours

Kiwivac offers a variety of accessories, including mops! You can polish timber floors, clean blinds, clean bi-fold door and ranchslider tracks and remove loose fur from your pet with our PetVac system.

Unlike other central vacuums, ours are also available in white! With white hoses and accessories, your vacuum will not only perform better, but also look better!

Central Vacuum Power Unit

These NZ made units are situated in the garage, basement or a cupboard, so long as there is adequate ventilation.

Our air watts range from 461am – 868aw.


Inlets are located, at the same height as your power points, in convenient places throughout your home to make vacuuming easy with a 9 metre switch hose.

As a general guideline, we recommend a 9 metre hose or shorter, unless it is absolutely necessary to go longer due to the construction of your home. Longer hoses are less efficient and more difficult to manoeuvre. You can choose from a range of colours.


This is placed in the kick-board of your kitchen, usually located under a set of drawers. This is piped in at the same time as the rest of the inlets.

In some situations a vacpan can be added to existing systems.

They can also be put into the laundry or any other room that has hard flooring, where you want to sweep up the small messes.

Garage Inlet

We can install an inlet in your garage so you can vacuum your car, boat, and garage. This can either be an inlet on the wall (like the rest of the house) or a utility inlet on the pipework coming out of the wall and going into the power unit.

Your wall inlet is piped at the same stage as your pipe out.
