About Airtest Co. LLC
Airtest Co. LLC operates in Lynnwood as a specialized HVAC testing, adjusting, and balancing firm. The company holds a 3.0-star average rating across 8 customer reviews. According to their website, they have been serving the Pacific Northwest since 1995, growing from a solo operation into one of the largest independent TAB firms in Washington State. Their portfolio extends beyond residential work to encompass hospitals, office buildings, and stadium facilities across the region.
What differentiates Airtest from general HVAC contractors is their focused expertise in test and balance procedures for complex building systems. Their website explicitly mentions servicing air handling systems, hydronic systems, domestic water systems, andfire life safety pressurization systems. The company utilizes what they describe as the latest technology while implementing industry best practices. They emphasize building partnerships with property managers and general contractors rather than positioning themselves as a full-service retail HVAC company.
A reviewer who has worked with Airtest for over four years specifically credits Adam and the team, describing the relationship as highly satisfactory. This marks the sole named technician acknowledgment across available reviews. The negative feedback present in the review record centers exclusively on road conduct issues with company vehicles, which represents a distinct concern category unrelated to technical service delivery.
What Customers Say
