How to Choose the Correct Central Vacuum

A lot of people are concerned about whether or not they know how to properly choose the correct central vacuum system for their home. This can be a daunting task for some, as they do not know which brands make quality equipment, along with how strong of a central vac that they actually need for their home. Since a lot of brands have started to lower their standards on quality, it is important to know who is providing the best available machines at the best price. (you can check out to speak with a specialist on these machines)

The first thing you should consider when purchasing a central vacuum is approximately how large your home actually is. Getting a rough estimate of the square footage can get you going in the right direction for choosing the correct power unit. Once you know the square footage of your home you should take that and double it, then find a central vac that is rated up to that amount. This is always recommended because when the manufacturers come up with these ratings they test the machines at the power unit, and not at an inlet valve which has an extensive run of pipe and then a 30-35ft hose attached.

A common misconception is that people need the absolute strongest machine if they want the most suction. This is a slight mirage of the truth. Central Vacuums that are designed for larger homes simply have a higher airflow in terms of CFM (cubic feet per minute). This higher CFM rating is needed in order to counteract the long runs of piping that are located throughout the home. You’ll see that central vacuums that are designed for the average American home only have about 200-300 airwatts less than the absolute strongest machines, this is due to that lower rating for CFM in the machine. A good quality machine should have somewhere in the range of 600-800 airwatts, this will provide enough suction for homes anywhere from 2500-6000 sq. ft. If you have a larger home you will want to go with a power unit that has atleast 1000 airwatts of power. This will insure that you have adequate suction at every valve in the home.

One of the most basic questions people ask is “what is the best central vacuum?” To answer this you need to look at all of the different specifications which make each and every central vac brand unique. The most important of these specifications are suction power (aka airwatts), warranty period, and the outer casing of the power unit.  You always want to go with a unit that is made of steel to ensure a long life. Central vac’s with metal casing are more durable and will stand up to the wear and tear of a 20 year lifespan. The suction power is also important, and can be characterized most accurately by the airwatts of a machine. The airwatts represent a mixture between the waterlift and the airflow, which are the two most important measurements. Choosing a central vacuum within the 650-800 airwatt range is the best, as it provides enough suction without overworking the motors. The final spec you should always consider is the warranty of the central vacuum. Most manufacturers warranty their product anywhere from 6-10 years for the motor & electrical components and a lifetime warranty on the power unit body. The longest warranty manufacturers offer is currently by Canavac. They offer a 15-20 year warranty on their motor & electrical components.

Overall when you really compare each brand head to head and apples to apples, Canavac seems to always come out on top. There machines are all steel, have strong suction (700-850 airwatts), and have the longest warranty in the business at 20 years. So when you are choosing a system for your home, use the guidelines we stated earlier and stick with a tried and trusted brand such as the canavac.

Thanks for reading and happy cleaning!
