Integration companies in the CE Pro 100 made it through 2007 without being negatively impacted by the slowdown in the U.S. housing market.

The list, which is in its tenth year, reported a leap in average income of 9 percent, from $6.8 million to $7.4 million. Other strong data includes a leap in the average installation price of 7 percent.

The revenue data bucks the one-year drop in overall volume that was reported last year, when the group cumulatively reported a 3-percent decline in revenues.

It also continues a three-year trend of increasing revenues-per-installation (a trend started back in 2005).

Over its 10 years, the prestigious list has changed from a list that used to include only traditional audio/video companies to a mixture of companies with roots in everything from audio/video and hybrid retail to automation and structured wiring, from security to high-voltage electrical and HVAC.

The top of the list itself reflects that diversity.

This year’s list is led by Pittsburgh-based Guardian Home Technologies with $37 million in multi-subsystem home technology revenue out of 19 locations. The company, overall, is a $120 million security company with roots in both residential and commercial alarm systems.

The No. 2 company is Houston-based Modia (formerly Home Theater Store), a regional hybrid retailer with 11 stores. And the No. 3 company is Audio Command Systems, a traditional high-end custom installation company with strong ties to the architectural community in the New York City area.
