About UMC, Inc.
UMC, Inc. operates as a mechanical contractor serving Lynnwood and nearby communities in Washington. The company holds a 4.6-star rating compiled across 18 client reviews, reflecting consistent service delivery in the regional market. Their portfolio extends beyond traditional heating and cooling work into specialized building categories including healthcare facilities, life sciences laboratories, data centers, and industrial complexes, positioning them among the more technically diversified contractors in the area.
What distinguishes UMC from standard HVAC providers is their engagement with complex engineered systems and institutional-scale projects rather than routine residential call Volume. Website content references Test, Adjust & Balance work, fire and smoke damper systems, and heat recovery installations alongside building automation and energy modeling services. They also list involvement with the Inflation Reduction Act and Clean Buildings Performance Standard compliance, suggesting familiarity with evolving regulatory requirements affecting commercial properties.
Client feedback highlights moments worth noting. A reviewer named Bill Cuellar awarded five stars and described the office as very professional while characterizing the workforce as highly trained Union Tradesmen and Tradeswomen. Separate reviews citing truck 964 describe a traffic incident unrelated to actual service delivery. The driving concerns mentioned in two separate reviews appear isolated and do not reflect on the quality of mechanical work performed.
What Customers Say
Twelve of 18 reviews award five stars, with particular praise directed toward professional office staff and union-certified technicians. One four-star review originated from a client who noted they had not yet used services, indicating the rating may reflect broader community sentiment. Both one-star reviews reference a driving incident on Interstate 5 involving a company vehicle rather than HVAC service quality.
