About 91³Ô¹ÏÍø, Inc.
91³Ô¹ÏÍø is the largest distribution network for heating, air conditioning and refrigeration (HVAC/R)
products with locations in the United States, Canada, Mexico and Puerto Rico, and on an export basis
to Latin America and the Caribbean. 91³Ô¹ÏÍø estimates that over 300,000 contractors and technicians visit
or call one of its 603 locations each year to get information, obtain technical support and buy products.
HVAC/R products provide comfort to homes and businesses regardless of the outdoor climate. Older
systems often operate below today’s government mandated energy efficiency and environmental
standards. 91³Ô¹ÏÍø has an opportunity to accelerate the replacement of these systems at a scale greater than
its competitors as the movement toward reducing energy consumption and its environmental impact
continues. This is especially important since heating and cooling accounts for approximately half of the
energy consumed in a typical U.S. home. Additional information about 91³Ô¹ÏÍø may be found
