MacDonald-Miller Facility Solutions has spent over six decades shaping the built environment across Spokane and the broader Pacific Northwest. Operating from 13 locations including dedicated sites in Spokane and Kennewick serving the Inland Northwest, the company employs more than 1,500 trained professionals delivering commercial-scale HVAC, plumbing, electrical, and building automation solutions.

Their Energy and Sustainability division offers building performance optimization through energy modeling, renewable system integration, and continuous monitoring.
