L&H Airco was formed in 1968 by Jack Handy, Gene Logan, Jim Hellwarth, Frank Wegener, and Tom Gilbertson with its headquarters in San Francisco, California. All were from The Trane Company, except Tom who came from Johnson Controls.

The idea to start this company came from Gene Logan and Jack Handy - thus the name L&H Airco. We also had an office in Sacramento and not long after the company started Gene opened another office in the San Jose area.

This original company was strictly a manufacturer's representative firm handling Chrysler Airtemp, Berry Blower, Mammoth Roof Top Equipment, Ceramic Cooling Tower, Bohn Heat Fransgier, Cosatron Air Purification, Tempmaster, and other complimentary lines of equipment.

In the mid 1970's L&H Airco became very involved in turn key field erected cooling tower projects employing the technology provided by Ceramic Cooling Tower. A similar and enhanced technology is now employed by Composite Cooling Solutions who we represent today.

Also in the mid 1970's we realized the necessity for a source of large custom made air handlers so we started a manufacturing facility in San Jose, CA where we manufactured custom air handlers up to 70,000 CFM in all configurations possible. By 1980 all Frank's partners had retired

By 1981 all Frank's partners had retired and L&H concentrated on the Sacramento market. Later that year, Chrysler Airtemp sold its manufacturing facility in Bowling Green, KY (now the home of the Chevy Corvette) and ceased manufacturing the large equipment which we had handled for several years.

Then in 1983 L&H Airco won a project to replace seven wood cooling towers at Pacific Bell/AT&T in Sacramento with all fiberglass cooling towers. This is the year we performed our first temperature control project and this was the first time we worked with Dick Racette who was then employed by Honeywell.

Dick became Frank's partner in 1988 and in 1990 we acquired the office staff and installers necessary to design and install Novar DDC control systems in addition to our manufacturer's representative business and turnkey cooling tower projects. At this time we represented McQuay and Pace Air Handlers along with Ceramic Cooling Towers.

In 1995 we became an Alerton DDC controls dealer and began to grow our Company from a staff of 6 to the present day 85. Service and customer training became a principle part of our business as well. As our control business grew, and we embraced the world of BACnet open protocol control systems, we decided to concentrate our manufacturer's representative business on field erected cooling towers and air Secure Aire air purification systems.

Our growth continued in 2000 when we entered the Fresno and Central California markets by opening an office in Fresno and Santa Barbara. Our installation base now extended from Kern County to the Oregon border with the only exception of the San Francisco Bay area. Growth continued and in 2004 we opened an office in San Diego. This office expanded our knowledge and experience with DDC controls and integration by installing Reliable DDC Controls, Trend Controls and Lynxspring's Niagara AX based control systems. Our presence on US Military installations took hold in 2008 and 2009 with several installations using Lonworks controls.

Integration of building systems beyond simple temperature controls has always been a goal of ours and in 2009 we became Encelium lighting control system representatives which has provided a base to grow into Retro-Commissioning work and Performance Contracting.

Our mission has always been to be recognized as the most knowledgeable and respected Temperature Controls & Energy Management System Contractor and HVAC Equipment Supplier in California.

Our purpose is to strive to combine technology with creative engineering to provide solutions for our customers. We are dedicated to providing the optimum value for our customers' investments while assuring the growth of our company and the people who contribute to its success.
