Alliance Air Products was established in 2004 as a custom air handler manufacturer, but has since grown into all areas of custom HVACR manufacturing. Alliance started business with 15 employees and 33,000 sq. ft. of manufacturing space. We have since grown to over 120 employees in 120,000 sq. ft., with an average annual growth of over 30%. Alliance is a privately held company with a very solid financial base, and has the capacity for rapid expansion in manufacturing capacity.

The Team:

President and CEO, Luis Plascencia has over 25 years of HVACR engineering background. Several of his design team members have over 20 years of HVACR experience.


The manufacturing floor has roughly 100,000 sq. ft. (under roof), mezzanine storage for completed projects of 20,000 sq. ft. and the managerial and engineering offices add another 5,000 sq. ft. for a total of just less than 125,000 sq. ft. Factory floor loading allows for a future doubling of current volume and additional adjacent (vacant) office space allows for growth into another 75,000 sq. ft., as demands for products increase.

We excel in database programming, having designed (in-house) our own selection software trade named ’ACES’ (Alliance Custom Equipment Selector). Moreover, our functional and technical experience extends to interfacing with third-party vendors and suppliers, utilizing the common technical design tools (AutoCAD, Office, etc.). At Alliance Air Products, we are continually expanding upon our knowledge and services to assist clients with successfully selecting the most efficient and cost effective solutions to their needs.
