The disadvantages associated with central vacuums start with cost. They are expensive to install, especially in existing homes, as retrofitting requires opening walls. The system's bulky hoses can also be inconvenient to maneuver and store compared to portable vacuums. Additionally, repairs may need professional service, adding to maintenance costs. Lastly, while powerful, they may be overkill for smaller homes or apartments, making the investment less practical for some households.

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.

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.

Yes, installing a central vacuum system typically adds value to your home. The ease of use, longevity, and superior suction power of a central vacuum system can add up to $2,000 to your home’s value if you decide to sell. Potential buyers may consider the central vacuum a perk to purchasing your home.
