The Air Conditioning Contractors of America (ACCA), has announced the winners of its third annual "Best Contractors on the Web" Internet Marketing Awards.

The winner in the Residential Category is AAA Indoor Air Quality, Portland, OR. The website, located at www.aaaiaq.com, was chosen for its visual appeal and ease of navigation.

The winner in the Commercial Category is Performance Building Services, Denver, CO. Their site, at www.pbservices.net, was described as professional, confident, and strong, clearly meeting the company's goal of promoting its reputation, experience, staff, and core business values to potential commercial clients rather than products. The site has also proven to be an invaluable employee recruiting tool.

"It was gratifying to see so many outstanding entries," says Paul T. Stalknect, ACCA president and CEO. "HVACR contractors are taking ecommerce seriously and doing a fine job of presenting themselves on the web. The winners are the best of the best, but we heartily congratulate all the finalists."

Dozens of contractors entered the competition. Other finalists were:

Residential Category - Doctor Cool & Professor Heat, League City, TX, www.doctorcool.com; Peaden Air Conditioning, Panama City,FL, www.peaden.com.

Commercial Category: Midstate Mechanical, Phoenix, AZ, www.midstatemechanical.com
