There are myriad reasons to add a central vacuum system to your home. Benefits include cleaning convenience, improved indoor air quality, durability, reliability, not having to lug an upright vacuum up or down the stairs (for more benefits, also check out MD Manufacturing’s 7 Reasons Why).
What you might not know is that many of the same people who work on your home theater projects are just as proficient at installing central vac systems in your home, as many custom electronics pros include the service in their technology offerings.
You may not have thought about it when you inquired about multiroom audio, but once you’ve swept up your kitchen and had everything sucked into the little kickstand below the sink and out to your garage-stored canister, you’d never want to go back to the traditional vac ways. Some systems even send you emails when the canister’s ready to be dumped.
Here are some basic starter tips if you’re considering a central vacuum setup, courtesy of Fred Harding of distributor Capitol Sales:
Always size the motor of your vacuum to include areas of the house that aren’t finished, like the basement.
When determining hose length, take a piece of 30-foot rope, and nail one end at the inlet location. Then walk about to ensure you will have adequate hose coverage. You can always swap in a longer hose, but why bother?
Only use 90-degree angles at the inlet. That keeps things from being sucked into the system that really should not be, like pencils, crayons and cats.
If you are installing a non-electric valve system, make sure the inlets are located near an electrical outlet.
If the vacuum canister is going to be installed in an attached garage, you must meet local and state building code requirements. Be sure to install a fire block between the inside and outside spaces.
Central vacuum motors draw a sizeable amount of current when they first turn on. Have the electrician install a 20-amp breaker dedicated to the vacuum system.
You don’t want to have the breaker pop when the vacuum is being run with another household appliance. It’s always a good idea to put surge suppression on the central canister.

It’s hard to imagine life without remote controls, but it’s been a long, strange path to the modern incarnation we know and love today.
Thanks Fred for great tips. A few clarifications though: 1) It is TIGHT 90 ells that should only be installed right at the inlet. You can use sweep 90’s in other locations but you do not want tight 90’s other than at the inlet. 2) It’s not a fireblock that needs to be installed on a firewall but rather you are required to penetrate the firewall with steel pipe. 3M also makes a product to assist in this. 3) Some central vacuums actually require a 30 Amp circuit with 10 gauge wire for the vac system. Be sure to check mfg specs. 4) Building code requires central vacs to be on their own dedicated circuit. Forget the surge protector issue except for protecting against lightining strikes. Hope this helps!
