Our company
Built on Multizone. Still Building Custom.
Custom Mechanical Equipment is a family-owned manufacturer in Ponca City, Oklahoma. We fabricate commercial HVAC, rooftop screening, and custom enclosures to field dimensions, one shop from drawings through powder coat.
Company timeline
How CME Grew With the Industry
Six milestones from one rooftop idea to a full manufacturing campus.
- 1986
The replacement concept
Dick Peitz designs a penthouse approach that replaces traditional multizone with independently zoned systems, without tearing out interior ductwork.
- 1988
First field assembly
The first unit goes on a school roof in West Bend, WI, proving the retrofit path in a live occupancy window.
- 1999
Custom Mechanical Equipment
Dick and Bill Peitz open CME to build custom multizone HVAC for commercial buildings nationwide.
- 2003
Ponca City, Oklahoma
CME relocates to 2101 Hall Blvd, more than tripling manufacturing space and adding power distribution, battery storage, and general fabrication under one roof.
- 2016
Custom Powder and Blasting
Sister company CPB joins the portfolio so screening, enclosures, and HVAC leave the shop with in-house powder coat and finish control.
- Today
PMZ3 and beyond
Erik Peitz leads as CEO and owner. The shop ships PMZ3 multizone units, rooftop screening, modular power centers, and custom metal work from the same Ponca City facility.

Erik Peitz
CEO – Owner
Erik grew up inside the business Dick Peitz started, from early field assemblies through today’s PMZ3 production line. As CEO and owner, he carries the same standard the company was founded on: equipment that fits the building, passes inspection, and stays serviceable for decades.
When you call CME, you are not routed through layers of account management. You get engineers and project managers who know how your penthouse was built and what your contractor needs on the roof.
Where we started
When Hot Deck and Cold Deck Stopped Making Sense
CME was founded to give building owners a practical replacement path when legacy multizone equipment no longer met efficiency and serviceability expectations.
From the late 1960s through the early 1980s, hot-deck cold-deck multizone units were standard on low-rise commercial and institutional buildings. As energy standards rose in the late 1970s, the industry needed a more efficient approach to zone control. Buildings still had the equipment. Nobody had a clean replacement path.
In 1986, Dick Peitz developed a different approach: replace the failed multizone with multiple efficient, independently controlled systems inside a custom rooftop penthouse. The first unit was field-assembled on a school roof in West Bend, Wisconsin in 1988. That proof changed what “replacement” could mean for owners who could not afford long outages or full duct rework.
The family kept refining the design. In 1999, Dick and his son Bill opened Custom Mechanical Equipment.

What we build
One Shop. Four Disciplines.
Contractors and specifying engineers come to CME when catalog equipment will not match the curb, the zones, or the inspection path. Everything below is built to your drawings and field dimensions.
Ponca City manufacturing
Field-Sized Before Steel Is Cut
CME is not a catalog rep house. We measure the roof, confirm curb and duct layout, and release shop drawings your engineer can review before fabrication starts. That process is why 5,000+ installations nationwide still trace back to one Oklahoma shop.
The Hall Blvd facility houses cutting, forming, wiring, assembly, and coordination with CPB for finish work. When the schedule compresses, you talk to people who built the unit, not a call center three states away.
