Data sources
Product rows in our catalog are keyed to AHRI certificate numbers and related certified performance fields (including SEER2, HSPF2, heating capacity, and COP at published outdoor temperatures when available). We enrich listings with manufacturer model identifiers and, where applicable, regional eligibility flags. Catalog inclusion means the combination appears in our verified dataset—not that we endorse a brand or installer.
- Primary key: AHRI certificate / matched-system reference
- Efficiency metrics: SEER2, HSPF2, COP @ published test points (e.g. 5°F, 47°F)
- Capacity: heating capacity at published outdoor temperatures when present
How hub “rankings” work
Type and brand hubs often sort featured models by HSPF2 descending, then SEER2 descending (nulls last). That order surfaces strong certified heating and cooling efficiency within the sample shown on the page. It is not a claim that a model is the best purchase for every home, climate, or budget.
Cold-climate badges on listings generally reflect catalog thresholds such as COP at 5°F and HSPF2. Always confirm capacity at your local design temperature with a Manual J (or equivalent) load calculation.
Cost and ROI estimates
Displayed prices and calculator outputs are planning aids. Installed cost depends on design, electrical work, ducts or line sets, permits, labor, and incentives. ROI and payback estimates require your utility rates, climate, backup-heat assumptions, and the exact equipment scope in a contractor proposal. We do not guarantee savings.
Sponsorship & affiliates
Sponsored placements are labeled. Affiliate relationships are disclosed on our affiliate disclosure. We do not sell catalog ranking positions tied to AHRI metrics.
