To understand the scope of the fraud documented in this report, it is first necessary to understand how the heat pump industry is structured. The pattern of multiple brands selling identical or near-identical products is not accidental. It is the direct result of a manufacturing model called OEM — Original Equipment Manufacturer — and the mechanism by which a small number of factories have flooded the North American market with non-compliant units under dozens of different names.
What OEM Means
An OEM is a company that designs and manufactures a complete product, then sells it in bulk to other companies that rebrand and resell it under their own names. The company doing the rebranding is typically called a “private label” or “white label” seller. The OEM manufacturer remains behind the scenes. The brand the customer sees on the box may have had no involvement whatsoever in the product’s engineering, testing, or manufacturing.
How One Factory Serves Many Brands
The OEM arrangement allows a single manufacturer to supply units to many brands simultaneously. Each brand receives the same underlying hardware, typically with minor variations in the external casing, nameplate, color, packaging, and sometimes the user interface or control software. The compressor, heat exchanger, refrigerant type, airflow path, and all performance-determining components are identical or nearly identical across all versions.
This is exactly what Nordica, Zymbo, and Wuxi Hammer have done in the North American market. Nordica produces a single double-duct heat pump platform that is sold under the names Ice Air, PMC Green, Applied Comfort, Islandaire, DesignLine, Dubbll, Techno, Waysos, GeoSmart NetZero, and others. Zymbo produces two platforms — the Clima Puro and the Dolphin 40 — which Williams, Waysos, Ortech, Silktech, Kinghome, Mits Air, and others sell. Wuxi Hammer manufactures the units sold under the Inspiron Air brand and also makes units for Multi MFG. Each of these brands presents the product as its own, with its own model numbers, brochures, and published performance data.
When the performance data originates from a legitimate, independently certified test, OEM manufacturing is a normal and legal commercial practice. Many reputable heat pump brands in North America source their products through OEM arrangements. The arrangement becomes fraudulent when the OEM manufacturer fabricates its own performance data, and every downstream private-label brand that reproduces or further inflates that data compounds the fraud. That is precisely what has occurred with every brand and every unit documented in this report. The fraud does not begin with the private-label brand; it begins with the OEM that invented the numbers. But the private-label brand that publishes those numbers, or adds its own inflated variations, is fully liable for every false representation it makes.
Why The OEM Structure Matters For This Report
The OEM structure has a direct and critical consequence for the legal exposure of every party in this supply chain. Because the same unit underlies all of these brands, a single laboratory test that disproves the performance claims of any one brand simultaneously disproves the claims of every brand using the same platform. A test on a Nordica unit is a test on the Applied Comfort, Ice Air, and Islandaire units. A test on a Zymbo Dolphin 40 is a test on the Ortech Solo, the Kinghome Dolphin 40, the Silktech EcoAuro 2.0, the Mits Air MITSWZ-40EC, and the Waysos Compact Aire 3K. The platform is the product. The brand name is a label.
This also explains why none of these brands will voluntarily submit to independent laboratory testing under AHRI 210/240. To test one is to test all. To expose the fabricated performance data of the Nordica platform is to simultaneously expose every brand that has built its product catalog around it. The OEM structure, which in a legitimate market creates efficiencies of scale, has in this case created a structure of shared fraud — one factory at the center producing false data, and a ring of private-label brands distributing that fraud across the North American market under the protective cover of different names and different model numbers.
This report documents precisely how that fraud operates — by platform, by brand, and by metric. Every number cited, every mathematical contradiction exposed, and every regulatory violation identified is ultimately traceable back to the same source: an OEM manufacturer that invented its performance specifications rather than measuring them.
