The Jamar Company

The Jamar Company has called Duluth home for more than a century, building a legacy that now includes multiple specialized divisions serving the Northland and beyond. You will find them at 4701 Mike Colallilo Drive in the city's industrial corridor, backed by a 4.6-star average from 14 client reviews. Their 24/7 emergency line at (218) 628-3624 ensures help arrives when systems fail after hours, on holidays, or during those brutal Minnesota winters that test every mechanical system in a home. Service calls are handled Monday through Friday from 8 AM to 5 PM, with their dispatch team coordinating across HVAC, plumbing, refrigeration, and roofing divisions under one corporate umbrella.

What distinguishes Jamar from regional competitors is their in-house fabrication capacity and multi-trade depth. Their draftingers and welders design and build custom metal products on-site, handling jobs too complex for contractors who outsource every piece. The company maintains a dedicated roofing division for emergency tarping and leak investigation, plus a commercial HVAC and plumbing team that executes entire mechanical projects from concept to startup. With APi Group as their parent company, Jamar accesses nationwide resources while retaining their Minnesota identity and workforce investments. Their safety-first culture is quantified: over 1.5 million crew hours logged annually across all divisions.

Customer stories from real Duluth clients reveal the human side of calling Jamar. When a ballasted rubber roof began leaking on a Sunday afternoon, one reviewer reports Jamar's on-call crew arrived before sunset, diagnosed the problem, and completed repairs the same day. Another client praised technician Mike, who repaired a damaged metal component from a hid-a-bed and restored full function. A property manager credited Jamar for squeezing urgent HVAC work into a packed schedule and making it happen. Multiple reviewers specifically mention Tammy at the front desk as a friendly first point of contact that sets the tone for every service call.
