History

From the late 1960's to the early 80's "hot-deck cold-deck" multizone units were the system of choice for design engineers in most low-rise commercial and institutional buildings. These systems mixed an inexpensive supply of hot and cold air to condition numerous, independently controlled zones in a building. When energy costs escalated with the oil embargo of the late 70's and early 80's, traditional multizone systems became obsolete due to the high cost of mixing hot and cold air simultaneously.

In 1986 Dick Peitz , owner and president of Custom Mecanical Equipment (CME), conceived an idea to replace existing, worn-out multizone units with multiple, highly efficient, independently controlled systems housed in a customized, rooftop penthouse structure. The first penthouse was field-assembled on the roof of a school in West Bend , WI in the summer of 1988. The success of this first venture proved the PMZ concept could provide a viable replacement for thousands of multizone units.

In 1996 a low profile 3 to 10 ton system was developed based on the same concept. The ability to provide up to 10 tons of cooling with zone control has been very successful. In addition, the PUV classroom unit was developed housing a high efficiency 2 stage furnace. The PUV continues to provide an economical design option for classroom HVAC, especially in the retrofit market.

In 2003 CME moved to Ponca City , OK to a more geographically centralized location in order to better serve its Nationwide customer base. The move to the new facility more than tripled manufacturing space and doubled office space. Much of the company’s infrastructure was also updated to allow for smoother customer service.
