HVAC · Formerly Eco Gas · Relaunch 2026
Eco-Kold.
Eco Gas became Eco-Kold in 2026 — same natural hydrocarbon refrigerant line, new name, new digital expression. Six years on this product, ten with the founder across multiple ventures. Rebrand week looks like any other Tuesday.
Four blends. One drop-in retrofit.
GWP under one.

Scope
New name. Same technical voice.
Eco Gas became Eco-Kold in 2026 — same product, same lab partners, sharpened name and identity. JKCA's work is the digital side: a new site that holds the rename, lays the four-blend product line out clean, gives the trust signals the room they earned but never had on the legacy site.
The work is new. The relationship isn't. Ten years with the founder across multiple ventures, six of those on this product line. The kind of decade-deep partnership where a rebrand isn't a re-introduction — it's the next chapter.
The product line
Four blends. Four jobs.

Trust signals
The work that earns the page.
EPA registration, third-party lab certification, university partners across the Americas. The credentials line was lost in the legacy site — it now reads as part of the brand.
