## Key takeaways

- EnergySage's cold-climate table lists Carrier Infinity and Rheem Endeavor Classic Plus at -23°F minimum operating temperature, and Daikin Aurora, Mitsubishi Hyper Heat and Trane 19 Multi-Speed Low Profile at -13°F.
- Top HSPF2 in that table is Mitsubishi Hyper Heat at up to 13.5, then Carrier Infinity at up to 12.5; HSPF2 is the number to prioritize in a cold climate.
- The NEEP cold-climate specification (v3.1) requires a COP above 1.75 at 5°F, HSPF above 10 for non-ducted or above 9 for ducted systems, and SEER above 15.
- The federal heat pump credit has ended for property placed in service after December 31, 2025. We did not test any heat pump; picks rest on published specs and analyses.

For cold climates, look at the **lowest rated operating temperature** and **HSPF2**. On published figures, **Carrier Infinity** and **Rheem Endeavor Classic Plus** list the coldest limit (-23°F), and **Mitsubishi Hyper Heat** lists the highest HSPF2 (up to 13.5). Daikin Aurora and Trane's cold-climate model list -13°F. We did not test any heat pump. Figures come from EnergySage's table (updated November 4, 2025), the NEEP specification, ENERGY STAR and DOE, read October 24, 2026. See [how we pick products](/how-we-pick/).

## Quick picks

| Best for | Pick | Min. operating temp. | HSPF2 (up to) |

| Coldest stated limit, lower stated HSPF2 | Rheem Endeavor Classic Plus | -23°F | 10.4 |
| Highest efficiency | Mitsubishi Hyper Heat | -13°F | 13.5 |
| Middle of the table on both measures | Daikin Aurora | -13°F | 10 |
| Lowest stated HSPF2 in the table | Trane 19 Multi-Speed Low Profile Cold Climate | -13°F | 9.2 |

Source: [EnergySage, best cold climate heat pumps](https://energysage.com/heat-pumps/best-cold-climate-heat-pump/) (updated Nov 4, 2025). "Up to" means the highest-efficiency configuration; your model number may be lower. EnergySage did not list SEER2 or warranty in that table, and the page does not state how models were selected. Always confirm the exact model's ratings on the manufacturer's spec sheet or the AHRI directory.

## What "cold climate" means

- **NEEP specification (v3.1, effective August 1, 2021):** COP greater than 1.75 at 5°F at maximum capacity; HSPF above 10 for non-ducted or above 9 for ducted systems; SEER above 15. Manufacturers report capacity and COP at 47°F, 17°F, 5°F and the lowest cataloged temperature. We read this version; check [NEEP](https://neep.org/) for newer ones.
- **ENERGY STAR:** says cold-climate units go through third-party verified testing down to 5°F, can keep running below that, and that pairing them with backup heat can be most efficient at lower temperatures.
- **DOE:** says a properly installed heat pump can deliver up to three times more heat energy than the electricity it uses, recommends the highest HSPF feasible in colder climates and a demand-defrost control, and advises shielding the outdoor unit from high winds.

## Product notes

### Mitsubishi Hyper Heat — highest efficiency
Listed at -13°F and HSPF2 up to 13.5, the highest in EnergySage's table. We could not read Mitsubishi's own product page, so confirm warranty and exact ratings for your model. <a href="#affiliate-link-pending" rel="sponsored nofollow">Check price</a>

### Carrier Infinity System — coldest limit with higher efficiency
Listed at -23°F and HSPF2 up to 12.5, the second-highest efficiency figure in the table. Confirm the specific outdoor and indoor pairing and the model's exact ratings. <a href="#affiliate-link-pending" rel="sponsored nofollow">Check price</a>

### Rheem Endeavor Classic Plus — coldest limit at lower HSPF2
Listed at -23°F and HSPF2 up to 10.4. The lower efficiency figure may suit buyers who put the cold limit first. <a href="#affiliate-link-pending" rel="sponsored nofollow">Check price</a>

### Daikin Aurora — -13°F rating
Listed at -13°F and HSPF2 up to 10. <a href="#affiliate-link-pending" rel="sponsored nofollow">Check price</a>

### Trane 19 Multi-Speed Low Profile Cold Climate — lowest HSPF2 listed
Listed at -13°F and HSPF2 up to 9.2, the lowest in the table. Confirm it meets the cold-climate criteria you care about. <a href="#affiliate-link-pending" rel="sponsored nofollow">Check price</a>

**Pros and cons across the group.** Pros: rated to heat at or below -13°F; efficiency far above resistance heat. Cons: higher upfront cost than basic equipment; ratings are for best-case configurations; installer quality and sizing matter as much as brand.

## What does it cost, and what might it save?

EnergySage reported that whole-home heat pump installations averaged about $19,000 in 2025, or roughly $16,500 after state and local tax credits and rebates (cold-climate guide, Nov 4, 2025). Its separate guide, updated June 29, 2026, puts the average new heat pump at $15,393 before incentives, with most installs between $14,353 and $25,957, based on marketplace quotes. These figures mix system types and scopes, so they do not match; use them as a range and get quotes.

Savings: DOE cites a NEEP study of cold-climate units in the Northeast and Mid-Atlantic that found average annual savings of about 3,000 kWh ($459) versus electric resistance heating and about 6,200 kWh ($948) versus oil systems. Those dollar figures reflect that study's prices, not today's. Your result depends on your fuel prices; see [Winter Heating Costs 2026–27](/posts/winter-heating-costs-2026-27/) and [Rates by State](/rates-by-state/). We do not guarantee savings.

## Sizing in cold climates

DOE's Building America sizing guideline says heat pumps should be sized to a Manual J load, and in heating-dominated climates heating capacity may exceed the load by up to 25%, versus 15% in cooling-dominated ones. It also recommends a balance-point diagram to size supplemental and emergency heat. Ask your installer for a written Manual J load calculation; see [how to choose a heat pump](/posts/how-to-choose-a-heat-pump/).

## Who should skip it (or wait)

- Homes with leaky envelopes or undersized or leaky ducts; fix those first.
- Homes where the electricity-to-fuel price ratio makes heating more expensive; compare costs per unit of heat.
- Buyers who expect a federal credit (see below).
- Anyone whose installer will not provide a Manual J calculation.

## Incentives

The IRS says the [energy efficient home improvement credit](https://www.irs.gov/credits-deductions/energy-efficient-home-improvement-credit) applies to improvements made through December 31, 2025, and had a $2,000 annual heat pump limit. EnergySage's June 2026 guide says the federal credit is gone and state rebate programs still pay out in many areas. A June 2026 [state Home Energy Rebates factsheet](https://building-performance.org/wp-content/uploads/2026/06/06.2026-State-Home-Energy-Rebates-Factsheet.pdf) reports that twelve states and DC have launched rebate programs (the document also says thirteen in its introduction) and that the rebates target low- and moderate-income households. Check your state's energy office and utility.

## Buying checklist

1. Lowest outdoor temperature you must heat at, and your design load.
2. Ducted or ductless, and the condition of existing ducts.
3. HSPF2 and rated capacity at 5°F for the exact model number.
4. Backup heat plan.
5. Manual J in writing; panel capacity.
6. Warranty and installer reputation. See [how to compare quotes](/posts/how-to-compare-solar-quotes/) for a similar quote checklist.
7. State, utility and local rebates.

## Limitations

EnergySage did not state its selection method, SEER2 or warranties. We could not read all manufacturer pages. HSPF2 figures are "up to." Prices are marketplace averages. This is not HVAC or tax advice.

## Frequently asked questions

### What is the best heat pump for cold climates?

On published specs, Carrier Infinity and Rheem Endeavor Classic Plus list the lowest operating temperature (-23°F) and Mitsubishi Hyper Heat lists the highest HSPF2 (up to 13.5). Which fits your home depends on ducts, sizing and installer quality.

### Do heat pumps work below zero?

Cold-climate models are rated to keep heating well below freezing; EnergySage lists minimum operating temperatures of -13°F to -23°F for the models here. ENERGY STAR says cold-climate units are tested down to 5°F and that backup heat can be most efficient at lower temperatures.

### What does cold climate certification mean?

NEEP's cold-climate specification requires a COP above 1.75 at 5°F plus minimum HSPF and SEER values. ENERGY STAR cold-climate certification uses third-party verified testing down to 5°F.

### Is there still a federal tax credit for heat pumps?

The IRS says the energy-efficient home improvement credit applies to improvements made through December 31, 2025. EnergySage's June 2026 guide says the federal heat pump credit is gone, while some state rebates still pay out.
