Best Central VAC Systems For Your Home With A Guide For How To Find One

All homeowners who are looking for the best and the most advanced way to keep their home clean at all times will have to consider central VAC systems. These systems are not a new thing, and they have been among us since the 19th century, but in recent years they became more popular than ever before. Here you will be able to see the central VAC systems reviews of the most popular systems that come with the most appealing features.

Guide for central VAC systems: Which factors must be taken into account?

Sadly there is no a unique or generalized rating system that can be taken into consideration and be used for ranking all of these VAC systems. On the other side, there are a lot of important factors that can be used in a unique combination to help you get the best and the most appealing VAC system of them all. This is precisely what we are going to do here. Below you can see main factors to consider when it comes to looking for the best VAC system.

Collection type

This factor refers to the collection system a VAC system uses. It can be either bagless or bagged. Both versions are decent and they offer great advantages, but bagless units won’t require from you to purchase replacement bags on a regular basis. Even if you have the best model available in the market, you will have to use one of these two options meaning that eventually, you will have to empty the VAC system.


This is a simple factor that refers only to the filtration mechanism a VAC system uses. There are countless options out there. Some use filters, others different filtering stages and others use permanent, self-cleaning filters. The last options are the best and the most cost-effective alternative. As the name suggests, they will clean themselves and they are extremely durable, so there won’t be any complications with it. Permanent filters have been used in commercial models with the best suction and massive size. Even today these filters are the best and very appealing.

HEPA stands for high-efficiency particulate air and it is simply the best and the most sophisticated system for air filtration there is. Always look for it if you are looking for the best unit of them all. HEPA filters are extremely effective, up to 99.98% and they offer the best value for money. Obviously, not all VAC systems support HEPA.

Square footage of a house

This factor can make a huge difference after all. In essence, each VAC system is designed and made for a house of a specific square footage. As such, we have models that are developed for 6.000 square feet, others for 7.500 square feet and some for 12.000 square feet. Obviously, your home will determine the need for the VAC system you actually need. It is always a better option to get a more powerful unit, simply because you will have the additional power when need it.

Noise (dB)

Nowadays most manufacturers started advertising the noise levels their VAC systems make. The lower is better actually. As such, we have models with 60-70Db. Those that have 58 dB are the best when it comes to noise generating.

The factor isn’t the most important of them all but can make a huge difference if you live with a big family in your home. Of course, you will want to consider do you have small children or don’t.

Main materials

There are several types of materials used in the construction process of the VAC systems. You can choose between steel, aluminum, metal and composite materials. As you may believe, steel is still the best option and the most durable one. Composite materials are decent, but they may get damaged easily due to the nature of the material. Aluminum is a decent alternative as well, but steel is simply the best. Try to remember that in a case of a repair, steel components will cost more.

Type of the motor

There are two types of the motors used in VAC systems. The first type is bypass engine, which won’t be directly in touch with water or debris. As you may deduce, this is a more appealing, or better said more desirable unit. It can last longer and the risk of a damage or a malfunction is much lower. Thru flow motors are the second option. The main issue is actually in their design, which makes them a less desirable option. The debris and water can reach the components of the motor and cause damage. That’s why always look for bypass motors. You definitely don’t want to replace a motor!

The diameter of the drive

Here we have an interesting factor to consider. The drive diameter can make a huge difference in determining the suction power of the entire system. As you may believe, the bigger is better in this case scenario. It cannot be generalized, due to the fact each brand may use its own drive diameter. On the other hand, all drive diameters that are 5.7 inches or higher are great options. Everything that is under 5.7 inches won’t be mentioned in the specifications, keep that in mind.

You may notice that some drive diameters are 7 inches. They are reserved for the most advanced and superior VAC systems and they offer impressive suction. Of course, you should consider them only if you are looking for the ultimate VAC system.

CFM (Cubic Feet per Minute)

As you can see, this refers to the Cubic Feet per Minute of vacuum flow. The bigger is better and simply means that the suction power will be better. It is actually one of the most important factors to consider and it can make a huge difference. Of course, you will have to be careful and to pay attention to the additional elements as well.

Installation cost

Central VAC system installation can be either affordable or very expensive. Models that are affordable to install are usually smaller and less powerful. On the other hand, we have units which may be expensive to install, but they are powerful and they can increase property value significantly. Installing a central VAC system also requires time, so be prepared for a few days or hard work and many adjustments in your home.


Amp is used to determine the power of the motor. And yes, the higher is better. Sadly, this doesn’t mean that a unit with a more powerful motor will have a better suction or another way around. The factor should help you see the potential of the system. A unit with a higher Amp of the motor has more chances to provide a much better suction.  Look for units with 15 Amp and you will make a wise choice. All motors which are rated under 13 Amp will have a hard time meeting your demands.

Water lift

As the title suggests, this factor refers to the ability of the system to lift water. The higher rating is much better. A combination of the water lift and CFM is known as air watts. One factor can significantly make a difference and affect the overall result. In other words, this combination refers to the suction power, but cannot be generalized.

Size of the main power unit

For some homeowners, this will be a crucial factor. Some models have a massive size, which doesn’t make them very practical. Others come in small packages so they can be installed anywhere. At the end of a day, it all depends on a specific unit and there is no possibility to generalize the matter. You should pay attention to the installation size in your home. A new central VAC system must fit it perfectly, period.

Motor stages

All motors found in these systems can be divided into a single stage or two stage models. Two stage motors generally provide more suction power and they are more appealing for more demanding operations. If you are looking for the best performances and you want them right now, these motors are the only option.

One stage motors are less capable when it comes to suction, but they are more durable, simply due to the fact they have just one moving part. Two stage versions have 2 more moving parts, so there are more chances for something to go wrong. After all, you can choose between simplicity and durability and simple power.
