Hamilton Sundstrand Launches Global Customer Response Center

FARNBOROUGH, England, July 19, 2010 - FARNBOROUGH AIR SHOW — Hamilton Sundstrand, a subsidiary of United
Technologies (NYSE: UTX), has begun construction of a new Customer Response
Center at its Windsor Locks, Conn., facility - an innovative central contact
point designed to respond to customer inquiries and collect data necessary to
coordinate response efforts across Hamilton Sundstrand's functions.

"Hamilton Sundstrand's new Customer Response Center will serve as a key
differentiator in the marketplace by providing a single data collection point
to coordinate issue resolution efforts across all Hamilton Sundstrand's
businesses, platforms and facilities, which is necessary given our product
and service offerings' complexity," said Matthew Bromberg, Hamilton
Sundstrand Customer Service vice president and general manager. "Our ultimate
goal is to keep our customer's aircraft in the air."

Work began in May to construct the Customer Response Center, which will
be staffed by engineers 24 hours a day, 365 days a year, to help keep
customer aircraft flying by addressing customer technical issues and aircraft
spare part orders. The center will feature new software to manage customer
inquiries and create a master database allowing Hamilton Sundstrand's
businesses to coordinate their efforts in addressing and resolving customer
issues as quickly as possible.

"Over the last decade, Hamilton Sundstrand's global customer base and
diverse product portfolio have grown tremendously," Bromberg said. "At the
same time, Hamilton Sundstrand's network of engineering, manufacturing and
repair facilities has become more complex, customer expectations are always
increasing, and airline maintenance strategies continue to evolve with total
support programs and multi-party partnerships."

Construction on the new 2,720 square-foot Customer Response Center is
expected to be completed in the fourth quarter of 2010. While the new
Customer Response Center is under construction, the operation is temporarily
located at an alternate location on Hamilton Sundstrand's Windsor Locks,
Conn., campus.

With 2009 revenues of US$5.6 billion, Hamilton Sundstrand is
headquartered in Windsor Locks, Conn. Among the world's largest suppliers of
technologically advanced aerospace and industrial products, the company
designs, manufactures and services aerospace systems and provides integrated
system solutions for commercial, regional, corporate and military aircraft.
It also is a major supplier for international space programs.
