MacDonald-Miller Facility Solutions

MacDonald-Miller Facility Solutions operates from Tacoma, Washington, as a mechanical contractor serving the greater Pacific Northwest with a footprint spanning 13 locations across Oregon, Western Washington, and Inland Northwest. Founded over 60 years ago, the company maintains a 3.6-star average across 17 customer reviews on Google, with service hours Monday through Friday from 7:30 AM to 4:30 PM and 24-hour emergency support available at 1-800-962-5979. The company employs over 1,500 experts and handles projects ranging from commercial high-rises to tenant improvements, with a dedicated 100,000 square foot fabrication shop in Seattle for prefabricated components.

What distinguishes MacDonald-Miller is their scale and vertical integration. As a full-service mechanical contractor, they handle design, preconstruction, fabrication, and ongoing service and maintenance under one roof. Their capabilities include HVAC, plumbing, electrical, building controls, and TAB (Testing, Adjusting, and Balancing), with in-house sheet metal fabrication allowing for faster project delivery. The company holds partnerships with major building owners and developers throughout the region, completing landmark projects like the T-Mobile Headquarters in Bellevue and Providence Swedish North Tower in Seattle. Their Energy and Sustainability division helps clients optimize building performance and reduce environmental impact through energy modeling and continuous monitoring.

Customer experiences vary significantly in recent reviews. Dan Kean, a chief engineer at JLL, praised the team as "the best" across projects ranging from small hot water coil replacements to 60-story high-rives, noting that technicians take pride in their work and have client best interests in mind. Travis Brooks specifically mentioned the company's Tacoma office in an historic brewery building. However, negative reviews raise concerns: Laurie Miller reported being ghosted after a same-day service request for non-functioning HVAC, receiving neither return calls nor email responses. Reviewer Drake Rockdow specifically warned against trusting technician Austin at any property. Joshua Cornutt and Natalie Peyton cited unmet service promises and concerns about the company's ICE detention facility work respectively.
