Aston, Pa.-based Topp Portable Air last week was named to the first-ever Inc. 5000 list of the fastest-growing privately held companies in the U.S.

The Inc. 5000, an expansion of Inc. magazine’s annual Inc. 500 list, includes many larger businesses this year. The awarded companies represent the fastest-growing movers and shakers in the small business world.

“Topp strives to provide the best total customer experience,” said Daniel Topp, president and CEO. “Receiving this award validates what we have been doing and strengthens our position in the HVAC industry.”

Topp Portable Air is No. 90 on the RER 100.
