Performance you can count on. Support you can count on.
Cold-climate equipment is only half the job. Z-Pro pairs −22°F rated systems with submittals, stocked parts and a support line staffed by people who know the product.
Cold Climate Performance
Z-Pro systems hold full nameplate heating output down to −13°F and keep running to −22°F — not the degraded output a standard heat pump gives you once New England weather actually arrives. Fewer callbacks, fewer complaints in February.
- Full nameplate heating output to −13°F
- Minimum operating temperature −22°F (−30°C)

Contractor economics
Cold climate performance. Margin you can work with.
Z-Pro runs on an EVI inverter compressor platform — full nameplate heating output to −13°F, operating to −22°F, AHRI certified and UL listed on R454B.
We import direct and supply the trade only, so pricing, technical support and fulfillment all come through one channel — and the margin stays with the contractor doing the work.
