MacDonald-Miller Facility Solutions

MacDonald-Miller Facility Solutions operates from 12911 NE Airport Way in Portland, Oregon, delivering mechanical HVAC systems to commercial clients across the Pacific Northwest. The company holds a 4.2-star rating drawn from 14 client reviews, with service hours running Monday through Friday from 7:30 AM to 4:30 PM. While the company serves Portland directly, its project portfolio stretches to Bellevue, Seattle, and Redmond, Washington, where crews have completed notable builds including the T-Mobile Headquarters and Providence Swedish North Tower. The firm handles design, preconstruction, fabrication, and ongoing service contracts for commercial and mixed-use properties, healthcare facilities, government buildings, and data centers.

What distinguishes MacDonald-Miller is its in-house fabrication capability, allowing technicians to build custom sheet metal components rather than sourcing third-party parts. The company maintains dedicated teams for building controls and electrical systems, providing integrated mechanical solutions under one contract. Their Energy & Sustainability division pursues certifications like Fitwel and manages the MacMiller Climate Pledge, reflecting a structured approach to reducing building carbon footprints. The firm also maintains a 24-hour emergency line for clients requiring after-hours response.

Client reviews name Thomas and Harley as service technicians who respond to heating and cooling calls with consistency. One reviewer describes them as knowledgeable friends who understand their equipment, recommending the pair for residential and light commercial needs. Another client notes the company's work spans sheet metal, electrical, plumbing, and building controls, trades that many regional contractors subcontract out. The negative review on record concerns parking obstruction during a 2019 project, with the reviewer noting street parking sat unoccupied 50 feet from the blocked entrance.
