Central Vacuum Cleaners 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.

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.

While caulking is handy for quite a bit of jobs, it’s still limited. Any crack or gap larger than 1/4 inch is best left for a more intensive repair job. When you hire house painters, they should run a thorough check to see what they need to repair before they start the job.

Large repairs that caulking typically won’t do well with include cracks or holes larger than a 1/4 inch, rotted wood, or metal surfaces, such as garage doors.

Routine service inspections on your central vacuum cleaner help keep your vacuum running at its best while helping to avoid costly repairs. It’s best to schedule service inspections every two to three years for a professional central vacuum service to examine your unit. If you have several pets in your home or have a lot of dirt and dust, it’s best to schedule your inspections every one to two years.

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.
