Cold-climate heat pump recommender.
AHRI + NEEP, filtered.
Enter your target tonnage and climate zone. See the NEEP-listed cold-climate models that qualify for HEEHRA and most state rebate programs.
What heat pump models qualify for cold-climate rebates?
NEEP-listed cold-climate heat pumps are required by most Northeast and Upper Midwest rebate programs. Target COP 2.6+ at 5°F for Zones 6-7, HSPF2 10+ for top-tier utility rebates, and variable-speed inverter compressors. The recommender filters the catalog by your tonnage + zone + system type.

Start with your target tonnage. If you haven't run a Manual J yet, use the heat pump calculator first — that gives you a credible tonnage starting point.
Then pick your climate zone. Zones 6-7 (New England, Upper Midwest) should almost always require NEEP listing; Zones 4-5 can be more flexible; Zones 1-3 can use mainstream equipment without cold-climate focus.
System type narrows to ducted central (when you have good existing ducts), ductless mini-split (when you don't, or want per-zone control), or ducted-mini (a hybrid option for attic + tight spaces). If you're not sure, run the decision quiz first.
Every unit in the catalog is AHRI-certified. The NEEP toggle filters to models on the NEEP Cold Climate Air-Source Heat Pump list. Most Northeast state programs require NEEP listing. For HEEHRA only, AHRI alone is usually enough.
Cold-climate equipment — frequently asked
NEEP (Northeast Energy Efficiency Partnerships) maintains the canonical cold-climate heat pump qualified products list. Most Northeast and Upper Midwest rebate programs — Mass Save, NYSERDA Clean Heat, Efficiency Vermont, Efficiency Maine — require NEEP listing for rebate eligibility. A heat pump without NEEP listing may still be AHRI-certified but will not qualify for those programs.
AHRI certification confirms laboratory-tested performance ratings. It's required for HEEHRA and most federal incentives. But for cold-climate-specific rebate programs (NEEP states), AHRI alone is insufficient — the unit must also be on the NEEP qualified list, which verifies capacity retention at 5°F and below.
At 5°F ambient, target COP ≥ 2.6 for Zones 6-7 (New England, Upper Midwest), ≥ 2.4 for Zones 4-5, ≥ 2.0 for Zones 1-3. Premium inverter-driven units land 2.7-3.0 at 5°F. Below COP 2.0 at 5°F, operating savings on cold days collapse and backup heat runs more.
Check the AHRI directory entry for "inverter" or "variable-speed compressor" language. Variable-speed units modulate output continuously, which is what delivers high part-load efficiency. Two-stage and single-stage units are cheaper but oversize easily and cycle more — they rarely qualify for top-tier rebates in cold climates.
Not exactly. Size for the nearest half-ton below your calculated load (this is the opposite of old contractor rules-of-thumb that sized UP). Variable-speed units modulate to match partial loads; oversizing forces short-cycling. The recommender surfaces units in a tonnage band around your target so you can compare options.
