Founded in 1933 by Louie and Theresa Drees, Drees Co. built its reputation on quality and service in heating equipment. Over the years, under successive ownership by Howard G. Drees, Douglas Drees, Kenneth Kammin, and later Howard J. Drees, the company expanded into mechanical contracting, adding divisions for electrical, temperature control, security systems, and more. In 2021, Alex and Derek Drees joined as co-owners, bringing new energy to our legacy. Today, Drees Co. employs over 70 professionals committed to excellence.

We offer a full suite of services across HVAC, plumbing, electrical, refrigeration, appliances, security systems, mechanical systems, and building automation systems, servicing both residential and commercial clients in Carroll, Iowa, and the surrounding region.
