Makes & Models · In development

Specific equipment, sourced and compared — not just categories.

The calculators model six generic system types. This section will go one level deeper — specification sheets and side-by-side comparisons for individual manufacturer models, sourced from NEEP's cold-climate list, ENERGY STAR's database, and published AHRI ratings.

This section is new. Model-level spec pages are in progress and will publish over the coming weeks. Heatpump Economics has no affiliation with, sponsorship from, or endorsement by any equipment manufacturer — every spec will be sourced and cited, and coverage will be updated as manufacturer lineups change.
