1) 5x more suction power than a regular vacuum means less debris is left behind and floors are cleaner.
2) The small dust particles that go through regular vacuum filters are re-introduced into the air to remain in the living environment. Central vacuum systems exhaust the dust outside of the living area, resulting in 70% fewer allergens than homes without central vacuums.*
3) Vac-pan automatic dustpans make sweeping easier. Just sweep to the vac-pan, press the button with your toe, and the debris is sucked away.
4) Central vacuum heads are lighter than standard vacuums so they are easier to use.
5) The filter is very large, so it does not need to be emptied as frequently as a standard vacuum.
6) Central Vacuums on average last around 20 years, making it a wise investment.

Hose attached to a central vacuum inlet
Central Vacuum systems are a shining example of technology making home life healthier. Central vacuums are a simple system of wall inlets distributed throughout a house that connect to a high powered central vacuum unit. Each inlet allows for a hose or accessory attachment rendering it a fully functional vacuum for lightweight but powerful vacuuming.The central vacuum unit is typically installed in a discreet and easily accessible location of the house such as a basement or garage.
Automatic dustpan
The systems can also include automatic dustpans attached to the wall for an extra quick and efficient clean-up.One of the best aspects of a central vacuum system is how well they completely remove dust, pollen, & animal dander from your home. Traditional vacuums don’t have the power or ability to vent outside of the living area, which makes central vac systems perfect for families with children, pets or allergy sufferers.
Central Vacuums have a limited lifetime warranty and on average last around 20 years which makes it a wise investment.
Avatar proved to be the highest-grossing motion picture release of all time, and when the initial Blu-ray Disc home release of Avatar went on sale yesterday, it came as no surprise that the blockbuster hit

Fifty years ago, it was easy to control the lights in one of the rooms in your home. The switch on the wall controlled the one ceiling-mounted light fixture, and it was either on or off. Since that time, lighting designers and homeowners alike have discovered the benefits of layered lighting, where a given room may have multiple lights with each serving its own unique purpose. Good lighting design takes the following into consideration:
The goal of any speaker is to accurately reproduce an original sound recording with accurate tonal quality and dynamic range, all the while achieving consistency across the frequency range. While speakers come in a variety of shapes and sizes, there are really just six primary forms of speakers for residential applications. Here’s a list of the six different forms, listed in order by their level of sound performance:
Tower/floor-standing speakersTower speakers usually have an array of at least three speakers, or drivers: a tweeter for high frequencies, a mid for middle frequencies, and a woofer for low frequencies. These three drivers are matched and configured to work together to produce consistent performance across the audible frequency range.In a perfect world, these speakers would be located a minimum of 30 inches from walls, aimed at the listening area and spread out around 30 degrees from the listening area.Advantages
Bookshelf speakersBookshelf speakers usually have an array of at least two drivers: a tweeter for reproducing high frequency sound, and a combined mid/woofer for middle and lower frequencies. While many bookshelf speakers produce great sound, it is a compromise from their larger, floor-standing brethren because it combines the mid and woofer drivers into one, compromising clarity. It is also more susceptible to boundary effects due to its typical placement on shelving or in cabinets. (This problem can be rectified by placing it on a stand, away from walls.) For best performance, these speakers are placed as close to ear height as possible and aimed at the listening area. These speakers also benefit greatly with the addition of a subwoofer to provide fuller sound at lower frequencies.Advantages
On-wall speakersThe on-wall speaker is essentially a bookshelf speaker with a form factor modified for an on-wall mounting application. On-wall speakers also usually have the same two-driver array where the tweeter takes care of high frequency sounds and a combination mid/woofer handles the lower frequencies. However, since it’s placed on the wall, these speakers are subject to boundary effects, but many models integrate compensation circuitry to compensate and minimize this.Advantages
Standard Definition – Also known as “four by three,” 4:3 or 1.33:1, this is the aspect ratio that was with television from the beginning. It’s what most of us are used to seeing when we see those old, large and heavy cathode-ray tube (CRT) televisions and monitors. It’s nearly impossible to find these TVs in stores anymore, as they’ve been largely rendered obsolete by the advance of much lighter and more energy efficient flat-panel plasma and LCD display technologies. Typically, programs produced in widescreen or movies in their original aspect ratios are severely letterboxed (black bars on top and bottom) when viewed on a 4:3 TV.
High Definition - Typically known as “widescreen TV,” high definition content is usually (but not always) distributed in a 16:9 aspect ratio and viewed on a matching widescreen TV. Nearly all television programs produced within the last five years are shot in a 16:9 high definition format. Widescreen TVs are also great for viewing movies in their original aspect ratios, as minimal letterboxing occurs. These TVs come in either the plasma or LCD varieties in a range of resolutions. 16:9 TVs display older content produced in a 4:3 ratio by surrounding the narrower image with black or gray sidebars. Alternatively, you can set your TV to either stretch the image to fill the screen, or zoom it to crop off the top and bottom of the image.
