Central Vacuum Systems questions, answered by experts

It can be difficult to know right away if your central vacuum is clogged since it operates quietly compared to regular vacuums. However, there are a couple of signs you can look for. If you feel like it’s losing suction or isn’t cleaning effectively, then there’s likely a clog somewhere. 

Make sure you turn the vacuum on and feel the end of the hose handle. If you don’t feel any suction, then you’re dealing with a clog in the hose. You can see if the clog is further down in the system by attaching the hose to each outlet until you find the one with the least amount of suction.

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.

The best way to clean central vacuum pipes is to use a maintenance sheet to dislodge clogs and wipe the inside of the pipes clean. Alternatively, a professional can clean your central vacuum pipes for you.

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.

Regular cleaning, sealing, and inspections help identify problems early and maintain aesthetics.
