We are proud to announce the promotion of Pat Roberts to Executive Vice President, Regional Market Development. With extensive experience since joining MacDonald-Miller in 1986, and having previously held the position of General Manager and Vice President of the Inland Northwest, Pat will now lead our sales and project management teams across Oregon and the Inland Northwest.

We had an amazing time welcoming students from Perry Technical Institute, who made the trip over from Yakima to visit our shop! They got to see our tool room up close and learn what makes MacDonald-Miller such a special part of the Northwest community. We look forward to seeing these future HVAC pros join our industry!

In honor of the late Brother Noel Brandon, MacDonald-Miller Facility Solutions has put together a team for the Mount Rainier Half Marathon held July 17-18th @ Crystal Mountain. More about this below:

Honoring Noel: Running to Support Mental Health Awareness

In honor of Noel Brandon, we invite you to join the MMFS RISE team at the Mount Rainier Half Marathon (July 17–18 at Crystal Mountain Resort).

This event is a meaningful way to recognize Noel’s passion for su***de prevention and mental health awareness, and to carry forward the values Noel stood for: setting goals, encouraging others, stepping outside of comfort zones, and finding meaning in the journey.

MacMiller is partnering with the event organization to celebrate Noel and his legacy. Employees, union members, family, and friends are all welcome to participate.

Whether you choose to run, walk, volunteer, or cheer from the sidelines with coffee and snacks in hand, there is absolutely a place for you. We’ll have a MacMiller pop-up on-site with refreshments and support.

Space is limited, so please complete both steps below as soon as possible:
1. Register on the Race Website BELOW

Building America one piece at a time!

Shout out to our awesome Detailing and Fabrication teams for their fantastic work on this pump skid project. From early layout and careful design to foreman feedback and a smooth shop build, everyone pulled together to make this a success. Highlights include faster detailing, a seamless workflow with the Stratus/SOF system, smarter material planning, and less field disruption, plus the customer benefited from a quicker, safer install. The end result: A one-lift setup straight from the truck to installation.

Quality work. Efficiently produced. Customer satisfaction!

Meet Gary Larkin, System Optimization Specialist, with MacDonald-Miller for over 25 years! In this employee spotlight, Gary shares what it looks like at the intersection of quality assurance, commissioning, and start-up coordination.

"Budgets get tight and time gets tight, especially at the end. That last 10% is what the owner remembers most. When the last 10% goes well, and they can tell we’re being conscientious, that’s what they remember. Finishing strong is very important for our company."

On the Grant County Sheriff’s Complex project, the team built prefabricated multi-trade racks to serve plumbing and HVAC for the cells, demonstrating how a faster install starts long before the jobsite!

Meet Nathan Gonzalez, Service Technician at MacDonald-Miller!

Q: What do people not understand about service work?

Nate: It can look like you’re “just doing maintenance,” but you’re constantly balancing: what can I check, what needs a deeper dive, and what can I finish today? You’re deciding what makes the most sense first: clean the coils, do the mechanical work, or what will give the best results for the customer.
