Default central vacuum installation

Does anyone know if it is possible to install a central vacuum system in an existing home without completely tearing up the walls? Our house does not have a basement. Can the tubes be run in the attic? If the vaccum tubes can be run through the attic does this increase the cost of the installation? Any idea of the cost to install this type of system in a 4 bedroom 2400sq. ft. home? Any information on this would be appreciated.

Tubes can be run through the attic. Nutone makes an inlet for use in existing construction.

Without seeing the actual layout of the house, I can only tell you to assume 1 inlet per every 600 sq. ft. and 16 ft of tubing for every inlet.

It's been a while, but I've done retrofit vacuum installs in the past with no drywall damage. It's not that difficult with the right tools.

The most important tools you need for a retrofit install are the 2-1/8" wood drill bit, a GOOD HEAVY-DUTY drill motor and a 4' - 6' drill bit extender for drilling fire blocks inside of the walls.

I've had my share of smashed knuckles, for sure. It's HELL when one of those 2-1/8" bits with a Hole Hawg behind it catches a nail! I also cheat a little bit by drilling a 2nd, smaller hole through the top plate I can look down through for spotting the drill bit on the fire block.

2-1/8" wow, we go with 2-9/16" here.. gives you some extra wiggle room in case things aren't perfectly straight.

But yes, you can do a retro.. unfinished basements and the backs of stacked closets are your friends.

You can run through an attic, but if this is in a cooler climate, may want to make sure you get some insulation on them, otherwise you may be adding some condensation moisture to the air mix and cause other problems.

Easier to hit the drywall nails, too.

I hate nails...

I should have mentioned the Closet & Cupboard option too for those who don't like the idea of drilling down.

Use a Milwaukee Super Hawg instead of the Hole Hawg, and use their 3 tooth hole saws. You will virtually eliminate smashed knuckles. I have also used a long galvanized pipe to knock out a pesky fire block.

I have cheated in the past when retro fitting a central vac system by running the pipes exposed in a closet and poking through to the wall in a bedroom. Most customer don't mind having a pipe running in a closet, and it certainly makes things a LOT easier that trying to get pipe down a wall in a tight attic!

Like anything retrofit (oldwork), it goes real slick...or it's a nightmare!!
I've used all methods above. the 3 tooth h-saw makes for easy drilling.
I would add,going up or down, try to stay on the inside walls.less chance of fire stop and usualy quite open and more forgiveing.
