In 1952 George Holden founded George Holden & Associates, Inc. (d/b/a Holden & Associates) in Atlanta GA as a provider of heating, ventilation and distribution equipment.  Holden & Associates was acquired in 1999 by Mingledorff’s Inc. , a leading distributor of HVAC equipment in the Southeast. This collaboration resulted in a company that has a wealth of knowledge and experience.  We are committed to providing our customers systems and service that support the vision and technical requirements of the building owner.
