In 1956 Harry Grant, a mechanical engineer with a strong background in air distribution, founded H.D. Grant Co., Inc.. Over the years, the company has represented many of the best manufacturer's lines in the HVAC industry.

Today, Harry Grant Jr. (Danny) owns and operates the company. H.D. Grant currently employs a staff of over 15 salespeople in Houston covering Southeast Texas.

In 1999 we moved our Houston office to a newly-constructed building and distribution center. We keep our warehouse in Houston stocked with exhaust fans, fire dampers, radiation dampers, single duct VAV boxes, fan powered VAV boxes with electric heat, Vibration Isolation, and many other products for the HVAC industry.

H.D. Grant's mission is to be the industry leader in customer satisfaction by providing quality products and services which are cost effective, innovative, and reliable.
