EAS started as Bullock & Humble Inc. Founded by James R. Bullock, Sr. and Edward Humble in early 1953 Bullock & Humble's primary focus was on heating, air conditioning and plumbing. With continued growth and success, in 1965 our first plant was built in Greensboro, NC (a 65,000 square foot facility) which is still in use today. In 1972, we created a sister company, Environmental Air Systems, for custom-built air handling units. The two companies later merged, creating the EAS of today.

In 2001, to handle the growing demand of our quality custom AHU products, we opened a second plant, our air handling unit and off-site construction plant, in High Point, NC .

Over fifty years of hard work and our unwavering commitment to our employees and customers have allowed us to grow to be one of the most successful mechanical contractors in the USA.
