Common repairs for central vacuum cleaners include motor repair, electrical repair, and blocked filters. Central vacuum motor issues typically come with a burning smell and loss of suction. With these issues, you might need simple lubrication to keep it running smoothly, or for more extreme problems, you could need a motor replacement. 

Electrical problems or losing suction strength, might be reasons to swap out electrical components for new ones. However, a local central vacuum repair professional can tell you the best plan of action for your system.

If your central vacuum has lost suction, you probably have a clog in the system. You can remove a clog yourself using a portable vacuum cleaner or central vacuum maintenance sheets. Stubborn clogs or damage to the system require a specialized technician to repair.

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.

A central vacuum system can be a worthwhile investment depending on your needs and budget. While the upfront cost is higher than a traditional vacuum cleaner, it offers significant long-term benefits. These systems can save you time and make cleaning your home easier, as you only need to carry the hose and vacuum head, eliminating the need to lug a heavy unit up and down stairs. They also tend to operate more quietly and can improve indoor air quality. The convenience and performance over many years may make it a valuable addition to your home if you can budget for the initial installation.
