The Best Heat Pumps for Cold Climates in 2026 (and How to Read the NEEP List)

The best heat pump for a cold climate is one that keeps most of its heating capacity at 5°F and does so efficiently: on published data, the Mitsubishi Hyper-Heating H2i and Fujitsu Halcyon XLTH lead the ductless field, while the Carrier Infinity 24 is the strongest ducted choice. Modern cold-climate models heat reliably at -13°F to -22°F, but the right pick still depends on your design temperature, your ducts, and whether you keep a backup heat source. Our picks below draw on manufacturer specifications, the NEEP cold-climate product list, ENERGY STAR data, and owner feedback.

Our picks at a glance

Best overall for cold climates: Mitsubishi Hyper-Heating H2i

Mitsubishi’s H2i outdoor units are the benchmark other cold-climate heat pumps get measured against, and they appear across the NEEP list in ductless, multi-zone, and ducted configurations.

Why we picked it

Mitsubishi rates H2i units for 100 percent of nominal heating capacity at 5°F and continued operation to -13°F. That is the number that matters on a January night: a 12k wall unit is still a 12k heater when it is 5°F outside, not a 7k heater. NEEP entries for popular MSZ-FS pairings list COP values at 5°F around 2, meaning roughly two units of heat per unit of electricity even in deep cold. Pair the same outdoor units with the SVZ air handler and you get a ducted cold-climate system. Efficiency ratings are excellent too, with single-zone SEER2 from about 21 to over 30 depending on size. Our Mitsubishi Hyper-Heating review has the model-by-model data.

Keep in mind

Below -13°F the unit shuts down heating, so homes with design temperatures in the negative teens need backup. Diamond Contractor installs cost more, and multi-zone systems give up some of the single-zone efficiency numbers. New units use R-454B.

Best ductless alternative: Fujitsu Halcyon XLTH

Fujitsu’s XLTH platform matches Mitsubishi on low-temperature capability and is often quoted a few hundred dollars less per zone.

Why we picked it

XLTH outdoor units are rated to keep heating at -15°F, a couple of degrees lower than Mitsubishi’s published floor, and they include a base-pan heater as standard equipment to prevent defrost water from freezing under the coil. Efficiency on the 9k and 12k wall units runs above 30 SEER2 with HSPF2 around 11 or higher, while larger sizes settle near 20 SEER2. Fujitsu also sells floor-mounted units that heat rooms more evenly in winter than a high wall head. Registered Elite Contractor installs carry a 12-year warranty. See the Fujitsu Halcyon XLTH review and our Mitsubishi vs. Daikin comparison for how the premium ductless brands stack up.

Keep in mind

Fujitsu’s dealer network is thinner than Mitsubishi’s in parts of the Midwest and Mountain West, and its app controls are less refined. Confirm the exact outdoor model is on the NEEP list; not every Fujitsu outdoor unit is an XLTH.

Best ducted premium: Carrier Infinity 24 with Greenspeed Intelligence

For homes with good ductwork, Carrier’s Infinity 24 is the most capable whole-house heat pump we can point to on published data, and it integrates cleanly with a gas furnace for dual-fuel setups.

Why we picked it

Greenspeed’s variable-speed compressor and vapor-injection design let the Infinity 24 hold useful capacity well below freezing; Carrier lists heating operation into negative temperatures, and many size-and-coil combinations qualify for ENERGY STAR’s cold-climate designation (check the AHRI certificate for your match). Efficiency is manufacturer-rated at up to 24 SEER2, with distributor listings showing roughly 20–23 SEER2 and up to about 11 HSPF2 by size. The Infinity System Control manages switchover to a furnace automatically. Full details are in our Carrier Infinity 24 review.

Keep in mind

This is a $14,000–$25,000 system before incentives, it requires Carrier’s communicating control, and the R-454B generation (27VNA prefix) saw supply constraints in 2025. In the coldest zones, size the backup heat to cover the full load on design days.

Best quiet ducted option: Bosch IDS 2.0 and IDS Ultra

Bosch’s inverter ducted heat pumps are quieter than most competitors and compatible with standard thermostats, which makes them a practical retrofit in older northern homes.

Why we picked it

The IDS 2.0 is rated up to about 20 SEER2 with HSPF2 in the 10.5 range on listings we reviewed, and its roughly 56 dB(A) outdoor rating is among the lowest for a top-discharge cabinet. Bosch markets a separate IDS Ultra model specifically for cold climates, with claims of full capacity in sub-zero temperatures; we have not verified those figures against NEEP data, so ask for the product’s NEEP or ENERGY STAR cold-climate listing before relying on it. Our Bosch IDS 2.0 review covers the lineup.

Keep in mind

The standard IDS 2.0 is not a cold-climate specialist; it needs electric strip heat or a furnace behind it in Zone 5 and colder. Bosch’s dealer network is smaller than the legacy brands.

Best value with a gas furnace backup: Goodman GSZV9 dual fuel

If you already have a working gas furnace, pairing it with an affordable variable-speed heat pump is the most cost-effective cold-climate strategy available.

Why we picked it

The GSZV9 is listed at a nominal 19.2 SEER2 and up to 22.5 SEER2 when matched with a Goodman furnace and coil, and it handles the mild and moderate hours, which are most of the heating season even in Minneapolis. A dual-fuel thermostat switches to the furnace below a set outdoor temperature, typically somewhere between 15°F and 30°F depending on local gas and electric rates. You get inverter comfort for much of the year at a heat pump price of $9,000–$15,000 installed. Read our Goodman GSZV9 review and the heat pump vs. furnace guide.

Keep in mind

Goodman does not publish cold-climate capacity numbers comparable to Mitsubishi’s, so this pick only makes sense with a furnace or robust strip heat. Listings we found show R-410A on the GSZV9; confirm whether you are quoted the R-454B successor.

Best budget cold-climate mini-split: Senville AURA

Senville’s AURA is the rare retail-priced mini-split with a credible cold-climate rating and ENERGY STAR certification.

Why we picked it

The AURA 24k single-zone is listed at 21 SEER2, 13 EER2, and 13.5 HSPF2 (Region IV) with heating rated down to -22°F, and dual-zone AURA kits reach 25 SEER2. Equipment costs $1,300–$2,300, and a licensed installer typically brings the total to $3,000–$6,000, roughly half the price of a premium single-zone install. Units ship pre-charged with R-454B. See our Senville AURA review.

Keep in mind

Senville does not publish capacity-at-5°F data with the detail of the NEEP-listed premium brands, so the -22°F figure is an operating limit, not a capacity promise. Support is by phone and email rather than through a local dealer, and many contractors decline to install owner-supplied equipment.

How to choose a cold-climate heat pump

Start with the NEEP list and ENERGY STAR cold-climate criteria

The Northeast Energy Efficiency Partnerships (NEEP) maintains a public database of cold-climate air-source heat pumps (ccASHP). Its Version 4.0 specification requires, among other things, a COP (coefficient of performance, heat out divided by electricity in) of at least 1.75 at 5°F at maximum capacity, and manufacturers must report capacity and COP at 47°F, 17°F, and 5°F. ENERGY STAR’s cold-climate designation uses similar thresholds plus minimum SEER2 and HSPF2 levels. Both lists let you look up exactly what a given outdoor unit produces at 5°F, which is the number a brochure rarely shows. Our SEER2, HSPF2 and COP explainer shows how to read those entries.

Capacity at 5°F beats “operates down to”

A unit that “operates to -22°F” may deliver only half its nominal capacity there. What you need is enough output at your design temperature (the temperature your location stays above 99 percent of the winter). Ask the installer for the NEEP capacity at 5°F and at 17°F, compare it with your Manual J heating load, and size for the load rather than the nominal tonnage. Our sizing guide explains how.

Plan your backup heat

• Electric resistance strips in the air handler are cheap and simple but expensive to run; keep them locked out above about 25°F so they only cover the worst hours.
• Dual fuel pairs the heat pump with a gas or propane furnace. The thermostat switches fuels at an economic balance point you set based on local rates.
• Keeping an existing boiler or furnace as a manual backup is common in retrofits with ductless heads; you simply set the old system’s thermostat a few degrees lower.

Defrost, drainage, and placement

Every heat pump defrosts its outdoor coil periodically in cold, humid weather, and that water must drain away rather than freeze under the unit. Mount the outdoor unit on a stand or wall bracket 12–24 inches above expected snow depth, keep it out of roof drip lines, and choose models with base-pan heaters where winters are icy.

What it costs

Typical installed prices in 2026, before incentives, are $5,000–$9,500 for a premium cold-climate single-zone mini-split, $12,000–$25,000 for a multi-zone or ducted Mitsubishi system, $14,000–$25,000 for a Carrier Infinity 24 with air handler, $10,000–$18,000 for Bosch IDS, and $9,000–$15,000 for the heat pump portion of a Goodman dual-fuel setup. Budget mini-splits such as the Senville AURA land at $3,000–$6,000 installed.

The federal 25C credit was terminated for property placed in service after December 31, 2025, so it does not apply to 2026 installs. Cold-weather states still offer some of the richest incentives in the country: Mass Save, NYSERDA’s Clean Heat program, Efficiency Maine, and utility rebates in Vermont, Minnesota, and Colorado, plus HEAR rebates for income-qualified households where states have launched them. Verify the current terms and use our cost calculator to estimate your net price.

Our recommendation

For a home without ducts, or one where you want room-by-room control, choose the Mitsubishi Hyper-Heating H2i and get quotes from two Diamond Contractors; take the Fujitsu XLTH if it has the stronger local dealer or a better price. For a ducted whole-house system, the Carrier Infinity 24 is the most capable option, with Bosch IDS as a quieter, lower-cost runner-up that needs solid backup heat. If you have a good gas furnace, a Goodman GSZV9 dual-fuel pairing delivers most of the savings for the least money. In all cases, confirm the exact outdoor unit is listed on the NEEP database and that its capacity at 5°F covers your load with the backup you plan to keep.
