Streimer

Streimer has operated from Portland since 1946, holding Oregon CCB license #2365 alongside licenses in Washington, California, Idaho, Nevada, New Mexico, and Arizona. With an average rating of 4.2 stars across 18 customer reviews, the firm serves residential and commercial clients throughout the Portland metro area, including neighborhoods in the Pearl District, Southeast Division corridor, and suburbs such as Beaverton and Gresham. The company maintains standard weekday hours from 7:30 AM to 4:30 PM and operates as a full-service mechanical contractor offering both new construction installation and ongoing service contracts.

What distinguishes Streimer from typical HVAC contractors is their vertically integrated manufacturing operation. The company produces custom HVAC ductwork, architectural metal shapes, and laser-cut components in-house under their proprietary METU System brand. This in-house fabrication capability allows the team to handle non-standard installations where off-the-shelf equipment fails to fit existing architecture, particularly in retrofitting older Portland homes with contemporary heating and cooling solutions. Their preconstruction division works directly with architects and general contractors during project planning phases, offering permitting assistance and material procurement before physical work begins.

Several reviewers mention working directly with named technicians. Ronald Shults describes a decades-long relationship with Laura and now her son, noting consistent follow-through on service calls. Brad Donohue recounts commissioning custom copper roofing materials fabricated on-site, describing the finished product as outstanding. Wilna Petersen emphasizes the staff's willingness to lend a helping hand on projects beyond standard HVAC work, suggesting the team takes a collaborative approach even when tasks fall outside typical mechanical contracts.
