Penn Air Group
24 / 7 Emergency Support


Herman Philhower founded Penn Air as a Test & Balance Engineering firm over forty years ago. From its humble beginnings in a home office located in a spare bedroom, the company’s reach has grown beyond its roots to include seven offices spanning from Guam to Puerto Rico. Each of these offices upholds its founder’s vision to provide specialized services with an insistence on quality, hard work, and responsiveness to our client’s needs.

The company’s ability to address challenging business climates, find and serve diverse markets, and expand its offerings has resulted in a firm that’s developed far beyond its founder’s dreams.
