Install Central Vacuum questions, answered by experts

Before deciding whether or not to install a central vacuum system, consider the pros and cons to determine if it’s right for you.

Pros

  • Increased suction power

  • Improved air quality

  • Reduced noise pollution

  • Longer lifespan than traditional self-contained vacuum units

Cons

  • Higher upfront installation costs

  • Expensive repairs

  • Requires significant storage space

Whether talking about a whole-house central vacuum or a portable vacuum cleaner, the expected cost of major repair work should always be balanced against its replacement cost. However, excluding high-cost motor replacements or major electrical trouble, repairs on a central vacuum system are typically far less than the cost of purchasing and installing a new one.

Experienced professionals don’t usually need to take down drywall to install the central vacuum. They are experienced in working in the tight spaces between walls and in crawl spaces to minimize any damage. The only drywall changes should be the holes cut for the new outlets. However, home design, existing plumbing, and other factors may require some modification. An estimate from a professional contractor should include information if any changes need to be made.

For the average-size house, a central vacuum installation usually takes one day of work by a team of professionals. Large houses may take two or more days. But if you are planning on a DIY project, it’s likely to take much longer. We suggest getting a few estimates for a project this big and fully understanding all the requirements before you make a decision about installation. Certain parts of your house may not be usable during the installation, and you may want to make other plans.

They’ll use more electricity than the average upright vacuum, but not remarkably more. Most power units plug into a standard 120-volt outlet and don’t have significant power demands. You shouldn’t notice an increase in electricity bills. If you have any specific questions about energy costs, ask your installer as you examine purchase decisions. Larger power units will need more electricity for their suction levels.
