What Blythe does

Blythe Mechanical Inc. is a full-service mechanical contractor headquartered in Bellingham, Washington, operating continuously in the Pacific Northwest since 1904. The company designs and installs plumbing, piping, HVAC and sheet metal, and commercial refrigeration systems (including ammonia systems) for commercial, industrial, educational, healthcare, government, military, hospitality, and food-processing facilities. Its core technical capabilities center on design-build and plan/spec mechanical delivery, using Building Information Modeling — specifically Navisworks and AutoCAD MEP — for 3D coordination, clash detection, and prefabrication planning, supported by an in-house fabrication shop and an inventory of more than 4,000 discrete parts.

The company operates two primary revenue streams: project-based mechanical construction contracts (fixed-price, multi-year engagements ranging from small repairs to large institutional builds) and recurring service and maintenance work, including 24/7 emergency response and tailored preventive maintenance contracts with 14-point HVAC equipment checks averaging twice per year. Engineering and preconstruction services — load calculations, value engineering, and BIM coordination — are offered either as part of project engagement or as standalone consulting. Pricing is quote-based and project-specific, with no publicly disclosed standardized tiers.

Blythe sells through an enterprise field-sales motion targeting general contractors for plan/spec subcontracts and direct owner relationships for service contracts, supported by a dedicated Lead of Business Development and affiliations with regional industry bodies (MCAWW, AGC, BIAWC, UA Local 26, SMW 66). Notable projects include the Naval Air Station Whidbey Hospital Retrofit, NAS Whidbey Hangar 6, the Angel of the Winds Casino expansion, Western Washington University's LEED Silver Academic Instructional Center, Anacortes High School, and the GSA Peace Arch Border Station (LEED Gold). The firm is privately held under management ownership following a 2003 buyout by David Morse III, and revenue is not publicly disclosed.

Core offering

Blythe Mechanical is a full-service mechanical contractor that designs, installs, and services plumbing, piping, HVAC/sheet metal, and commercial refrigeration systems for commercial, industrial, and institutional buildings. Projects are delivered through Design-Build (single-source design plus installation) and Plan/Spec (fixed-price construction to architect specs) methods, supported by in-house PE-licensed engineers and BIM coordination. The company also provides 24/7 mechanical service and preventive maintenance contracts across the Pacific Northwest.

Product overview

Blythe is a full-service mechanical contractor offering a unified portfolio of mechanical construction services rather than a software platform. The core offerings include Plumbing and Piping Services, HVAC/Sheet Metal and Airside Mechanical Systems, and Commercial Refrigeration (including ammonia systems). These services are delivered through two primary delivery methods: Design-Build Services (where Blythe provides single-source responsibility for engineering, installation, and system function) and Plan/Spec Services (traditional fixed-price construction). Supporting these are Engineering Services with in-house professional engineers, and 24/7 Mechanical Service and Maintenance with a Preventive Maintenance add-on program. The company serves diverse sectors including Commercial/Industrial, Education, Government, Hospitality, Medical, Military, and Agriculture/Food Processing. With over 120 years of experience since 1904, Blythe operates throughout the Pacific Northwest from its Bellingham, WA headquarters.
