MacDonald-Miller Facility Solutions is committed to the Inland Northwest, and our support of Spokane Velocity FC and Spokane Zephyr FC reflects that commitment. These clubs bring pride and community connection to Spokane. We’re proud to be a 2026 sponsor.
Just as a strong football team relies on preparation and coordination, high-performing buildings rely on the right team behind the systems to ensure they deliver day in and day out.
Our Spokane team delivers full mechanical design and construction services, including HVAC, plumbing, electrical, sheet metal, controls and commissioning. A coordinated approach helps reduce project risk, improve installation quality and keep schedules on track.
We provide commercial HVAC maintenance and repair for facilities of every size. Our service technicians handle boilers, chillers, air handlers, heat pumps, rooftop units, electrical systems, and building controls. The goal is to prevent downtime, extend equipment life, and keep occupants comfortable.
Improving energy performance is one of the fastest ways to reduce operating costs. We support benchmarking and compliance with Washington’s Clean Building Code, equipment retrofits, advanced control upgrades, and long-term energy and financial planning. Many customers look to us to help improve building efficiency, indoor air quality and compliance with emerging Northwest performance standards.
MacDonald-Miller provides integrated mechanical, HVAC and energy services for businesses throughout Spokane and the Inland Northwest. Whether you operate a small business or a large commercial facility, or a campus, our team helps you build, maintain, and improve the systems that support comfort, safety, and efficiency.
