Midstate Mechanical was selected to provide renovation services to this three-story, 76,000 square foot museum, which originally served as Monroe Elementary School. The ten month project included a complete renovation of the HVAC and plumbing system which required cooling towers, 25 heat pumps, and two air handlers.
The heat pumps were 900 lbs each and figuring out how to hang these in this historic building became one of the challenges faced on the renovation. With the obvious challenges and hurdles presented by a historic building remodel, Midstate moved forward with innovations, design changes on the fly and a “can do” attitude. With just over (12) men manning the project and seeing to all its requirements, we proved ourselves again, to be the contractor of choice. From “floating” equipment and material across rollers inside a 100 year old attic space to laying out equipment locations throughout the building prior to final design. The three floors of remodeling comprised all facets of mechanical construction.

Midstate Mechanical was selected to provide mechanical services for the renovation of the Heard Museum. The 26,645 square foot facility in Phoenix, Arizona is a private, non-profit museum founded in 1929 by Dwight B. and Maie Bartlett Heard to house their personal collection of cultural and fine art. More than seven decades of history have transformed the world famous Heard Museum into what USA Today describes as “the nation’s most prestigious private Indian arts center.”
The project called for demolishing a building and building a new one in its place. Underground ductwork was used beneath the new building to air condition an existing building. A temporary DX system was installed while the new chilled water lines were run and new ductwork installed. One gallery had to be air conditioned and operational after the unit was demolished. Humidification was achieved by new humidifiers and dehumidification coils with hot water from two new boilers. All this was accomplished while the building was occupied and open for visitors during regular operating hours.
