About Zero HVAC Direct
Built around the contractor.
Zero HVAC Direct supplies Z-Pro cold-climate equipment to licensed HVAC contractors across New England through a trade-only sales model.
The company
Trade focused by design.
Zero HVAC Direct sells to licensed HVAC contractors and dealers — the people who size, install and commission equipment for a living. It does not sell to the public, and it does not operate a retail storefront.
That shapes how the site works. The catalog, the specifications and the document library are open, because a contractor needs them to quote a job and pull a permit. Pricing is the part that happens in a conversation.
The company describes itself as a NEHPA-registered distributor and supplies the Z-Pro line to contractors working across the six New England states.
Evidence
What the documents show.
Two things are worth stating separately and precisely: what the certificates establish about the equipment, and what Zero HVAC Direct does commercially.
Equipment evidence
ZERO appears on active AHRI certificates
ZERO is the outdoor-unit brand name on five active AHRI Certificates of Product Ratings, references 218043726–218043730, covering matched ZMSB outdoor and ZWAVAG indoor systems rated to AHRI Standard 210/240-2024 and listed for sale in the USA and Canada.
Those references can be looked up independently in the AHRI directory. They cover the documented matched systems, not every model in the catalog.
Open the certificatesOur role
Zero HVAC Direct supplies the Z-Pro catalog
Z-Pro is the equipment line stocked and sold through Zero HVAC Direct — 26 models on R454B, rated for operation to −22°F. The company's role is commercial: stocking the line, publishing its documentation and supporting the contractors who install it.
The model
Trade only, not retail.
What that means in practice, on this site.
A public catalog, no public prices
Every model, specification and document is open to read. No price appears anywhere on the site, and there is no cart or checkout.
Pricing is quoted, not listed
Trade pricing is requested through the contractor pricing form, which asks for company and licence details.
Documentation before the conversation
Manuals, submittals, engineering data and AHRI certificates are published for contractors to check before contacting anyone.
A technical line, not just a sales line
Product selection, system design, commissioning and troubleshooting are handled by technical support. Warranty registration has its own contractor workflow.
