Heat pump selection
5 Best Heat Pumps for Home in 2026
The short answer
Start with a stated load and workable duct network. Compare Carrier 27VNA3 for a communicating ducted route, Bosch IDS Ultra for cold-weather ducted research, Mitsubishi intelli-HEAT for a retained-furnace design, Mitsubishi MSZ-FX12NL with MUZ-FX12NLHZ for named room coverage, and WaterFurnace 700A11 for a designed ground loop. Exact matches and site work still need proving. There is no fixed winner.

The best heat pumps are full systems that fit the house's load, duct network and winter design. A ducted family, ductless room pair and ground-source unit do different jobs. This shortlist uses current maker records to name five research routes. It does not rank every model by reliability or promise a fixed installed price or bill saving.
Start with a stated load and workable duct network. Compare Carrier 27VNA3 for a communicating ducted route, Bosch IDS Ultra for cold-weather ducted research, Mitsubishi intelli-HEAT for a retained-furnace design, Mitsubishi MSZ-FX12NL with MUZ-FX12NLHZ for named room coverage, and WaterFurnace 700A11 for a designed ground loop. Exact matches and site work still need proving. There is no fixed winner.
We reviewed the linked source-owner records on October 14, 2026. The list compares use cases and stated features. We did not install the products, measure their sound or conduct life tests. No customer star rating is used as a performance score.
Family pages help build a shortlist. The real indoor/outdoor match and controls decide the supplied system's rating. Keep full model suffixes and the matching record where stated. A family ceiling must not be copied to every capacity.
1. Carrier Infinity 23, 27VNA3: communicating ducted option
Carrier Infinity 23, 27VNA3
Our verdict:
Communicating ducted research
Consider when the house has a written ducted design and the proposed control setup suits the project. Ask for the real indoor/outdoor match, winter output and accepted network with the quote.
Read the project guide- Variable-speed outdoor family
- Designed with Infinity System Control
- Full indoor combination decides the supplied rating
Keep in mind: A family rating ceiling is not every match. A low working limit does not prove full winter heat. The old indoor unit and controls need an approved setup.
Product details checked October 2026
Carrier's current 27VNA3 page explains variable-speed use and Infinity System Control. It publishes family ceilings up to 23 SEER2 and 10.5 HSPF2. Those are maker records, not the rating of every possible new match.
Consider it when: a stated ducted communicating system fits the house and local service setup. Keep in view: the real indoor unit and controls belong in the bid. An old thermostat or retained indoor coil must not be assumed to give the full advertised setup.
| Question | Record for the bid |
|---|---|
| Which outdoor model | Complete supplied suffix |
| Which indoor unit | Complete approved match |
| Which controls | Real included Infinity arrangement |
| Which winter duty | Output and backup at stated design conditions |
Scroll for more →
Ask the bidder to connect the new match with the load and duct network. A high cooling ceiling does not prove the best winter fit. An advertised working limit does not show full heating coverage at that limit.
Use heat pump installation prices for a US budget scope. Do not read Carrier's broad guide as a fixed installed price for this family, match or house.
2. Bosch IDS Ultra: low-temperature ducted option
Bosch IDS Ultra with BIVA Ultra
Our verdict:
Low-temperature ducted research
Consider when winter output is central to a ducted check. Keep the complete pair, its performance curve and the house load so the capacity claim has a real design scope.
Read the project guide- Ultra outdoor series with documented BIVA Ultra pairing
- Manufacturer publishes low-temperature performance
- Exact pair and backup need a project record
Keep in mind: A family claim is not a seasonal COP or a promise of enough heat for every house. Power and backup duties still need check and pricing.
Product details checked October 2026
Bosch's IDS Ultra page gives the current cold-climate research route. Its BIVA Ultra air-handler record clearly pairs that indoor series with the Ultra outdoor series. Keep the exact pair and its submittal for the quote.
Bosch advertises full heating capacity at 5°F with COP 2.1 under its stated conditions. Treat that as a maker claim for the stated system. It is not proof of enough output for every house there or a seasonal COP for every winter.
Consider it when: cold-weather ducted performance is central to the check. Keep in view: a capacity-retention claim needs a stated output and the home's load alongside it. Power and backup work still need their real scopes.
| Question | Evidence |
|---|---|
| Which Ultra match | Full outdoor and BIVA suffixes |
| What output at design conditions | Selected pair's performance record |
| What backup remains | Real source and control plan |
| What ducts remain | Accepted network and blower duties |
Scroll for more →
Use cold-climate heat pump cost for the winter-focused project scope. The cold-climate label does not create a fixed installed premium or promise zero resistance heat.
3. Mitsubishi intelli-HEAT: dual-fuel compatible option
Mitsubishi Electric intelli-HEAT
Our verdict:
Retained-furnace dual-fuel research
Consider when the planned project keeps a written combustion source for backup. Keep the furnace model and real coil/outdoor/control setup with both the technical and price records.
Read the project guide- Designed as a conventional-furnace dual-fuel route
- Indoor coil, outdoor unit and controls form the system
- Existing furnace acceptance remains project-specific
Keep in mind: The product route does not accept every older furnace. It does not renew all retained parts or promise the lowest bill under every tariff.
Product details checked October 2026
Mitsubishi's intelli-HEAT record explains a dual-fuel route using a standard furnace and ductwork with its designed heat-pump setup. The indoor coil, approved outdoor family and controls must be chosen as a system. It does not certify every existing furnace for reuse.
Consider it when: keeping a stated furnace-backup route is part of the goal. Keep in view: the retained furnace's acceptance and supply duties remain stated. The new heat-pump package is not a full renewal of all old heating parts.
| Question | Record |
|---|---|
| Which furnace remains | Full model and accepted scope |
| Which indoor coil | Approved supplied intelli-HEAT arrangement |
| Which outdoor unit | Real compatible full model |
| Which controls | Approved source handoff and included functions |
Scroll for more →
Ask what happens to the older cooling coil and controls. Count changed parts once. If the bid replaces the furnace too, keep the new source within the package scope instead of adding another full furnace allowance.
The dual-fuel guide keeps old and new source duties apart. Its control plan needs a real project answer. There is no fixed changeover temperature here. Nor is the lowest bill promised under all rates.
4. Mitsubishi MSZ-FX12NL with MUZ-FX12NLHZ: ductless option
Mitsubishi MSZ-FX12NL with MUZ-FX12NLHZ
Our verdict:
Defined single-zone room coverage
Consider for a named room or zone without adding a central duct network for that duty. Ask for the full pair, winter output and real location and coverage plan.
Read the project guide- Outdoor and wall-mounted indoor family route
- Single-zone research example
- Exact capacity pair and room loads required
Keep in mind: One indoor head does not show whole-house heat. Closed rooms, other floors and any retained heating need a clear design scope.
Product details checked October 2026
The maker's MSZ-FX wall-mounted page gives a current indoor family route. Its US catalog lists the MSZ-FX12NL and MUZ-FX12NLHZ match. This example does not set your room size or duty. Ask for the supplied suffixes and the full pair's load and output records.
Consider it when: a named room or zone needs heating and cooling without a new central duct network. Keep in view: the plan must cover real rooms, closed doors and local design conditions. One indoor head is not automatic proof of whole-house coverage.
| Question | Record |
|---|---|
| Which rooms | Stated heating/cooling load and coverage |
| Which pair | Full indoor/outdoor suffixes |
| Which location | Designed indoor/outdoor placement and access |
| Which site work | Power, routes, drains and restoration |
Scroll for more →
A ductless route can serve an addition or named area without being the swap for all existing heat. Keep that duty clear in cost checks. A one-zone bid and a full whole-house ducted package should not be treated as equal jobs.
The room chart tool gives a limited cooling starting point. Its source has clear coverage limits. It does not design winter heat. It does not choose a whole-home multi-zone system. Use actual room loads and full pair records for that project.
5. WaterFurnace 7 Series 700A11: ground-source option
WaterFurnace 7 Series 700A11
Our verdict:
Designed ground-loop project
Consider when loop readiness is part of the project and the real indoor and distribution design is written. Keep source equipment, loop work and restoration visible in the full quote.
Read the project guide- Water-to-air ground-source unit
- Variable-capacity source and variable-speed blower
- Ground loop needs a site-specific design
Keep in mind: The indoor product record does not show loop price or site readiness. Ground-source rating conditions are not an air-source winter-use forecast.
Product details checked October 2026
WaterFurnace's current 700A11 page explains a variable-capacity water-to-air system with a variable-speed blower and loop-pump route. The ground loop needs its own real design. The indoor unit page does not price a full drilled or trenched project.
Consider it when: site readiness and a designed loop are part of the planned project. Keep in view: access, loop work and restoration can be major scope differences from an air-source swap. A high published COP under ground-loop rating terms should not be copied into an air-source winter-use model.
| Question | Record |
|---|---|
| Which indoor source | Full model and stated performance |
| Which loop | Site-specific design and work boundary |
| Which distribution | Accepted ducts and room duties |
| Which outside work | Access, permits and restoration owners |
Scroll for more →
Use cost to install geothermal HVAC for that larger scope. Keep loop design, unit and site work distinguishable even when a contractor supplies one full package amount.
Ground source does not use outdoor air as its heat source. That difference alone cannot choose it for your home. The loop, indoor system and installed scope still need a workable site design.
Best heat pumps: factors to consider
| Research route | Current example | Main proof still needed |
|---|---|---|
| Communicating ducted system | Carrier Infinity 23, 27VNA3 | Real indoor/control match and rating |
| Low-temperature ducted system | Bosch IDS Ultra with BIVA Ultra | Design-condition output for the selected pair |
| Retained-furnace dual fuel | Mitsubishi intelli-HEAT | Approved furnace/coil/outdoor/control arrangement |
| Defined single-room coverage | Mitsubishi MSZ-FX12NL with MUZ-FX12NLHZ | Complete pair and room-load basis |
| Ground-loop system | WaterFurnace 7 Series 700A11 | Site-specific loop and full system design |

The order is for navigation across those jobs. It does not claim the fifth product is less reliable or that the first has the lowest cost. Ground-source and air-source efficiency records also have different test conditions.
The current house load is the starting point. ACCA Manual J explains the residential method and Manual S addresses choice. An old furnace input or AC ton label is useful history, not a current heat-loss calculation.
| Factor | Useful record |
|---|---|
| Winter conditions | Output/COP at the stated design temperature |
| Cooling duty | Total and sensible/latent load |
| Distribution | Accepted ducts or defined room coverage |
| Power | Stated supply assessment and work scope |
| Backup | Real source and approved controls |
| Service | Local support and written terms |
| Budget | Full installed scope, not outdoor equipment alone |
Scroll for more →
Keep the factors with the exact new match. A rating record, output curve and install scope answer different questions. None should be replaced by a high family ceiling or a simple square-foot rule.
Read ratings without overstating them
SEER2 rates cooling under its test method. HSPF2 rates heating under its method. COP compares useful heat with power input at stated conditions. Each has its own role. None is a yearly bill value.
For the real chosen match, keep the stated records rather than the largest number on the family page. A model can operate at a low temperature without producing enough heat for a high-load home there. An output and load check remains necessary.
| Claim type | Correct reading |
|---|---|
| Family efficiency maximum | Ceiling available within the documented family |
| Complete match rating | Evidence for the named match |
| Low operating limit | Operation under stated conditions |
| Capacity at a temperature | Output to compare with house duty there |
| Sound minimum | Stated test/operating condition, not sound at your window |

This framework helps shortlist without pretending the source owner measured your home. Ask the bidder for the chosen system records. If it is missing, keep the claim tied to your stated inputs instead of copying a similar variant's result.
Installation quality and scope
A full bid should name the outdoor unit, indoor unit, controls and backup. Keep duct network, power and refrigerant work clear. Record removal, access and restoration with their price states.
EPA's Section 608 guidance supplies service context. This site does not give charging instructions or accept old/new fit from a photograph. The exact model-approved setup and the written plan decide that scope.
| Price line | Budget treatment |
|---|---|
| Complete installed bundle | Count once within its written boundary |
| Separate site extra | Add the real priced task once |
| Shared indoor equipment | Do not add another full allowance if included |
| Unpriced needed work | Keep unknown beside the subtotal |
Scroll for more →
The cost tool follows those rules. Its typical amount comes from source-range midpoints. It is a planning amount. It is not a measured local median or a price for each model here.
Cold-weather and room-fit options
If cold-weather output is the leading question, read best heat pumps for cold climates. That list keeps full-load coverage and backup distinct from working-limit marketing.
If the choice is whether to retire a furnace, read replace furnace with heat pump. It names service readiness and old-source duties. A new outdoor unit's price is not the entire conversion budget.
For sound ducts and gas service, compare heat pump vs furnace. Use the same delivered heat on both sides. If only cooling changes, use the heat-pump/AC guide. Keep the old heating role clear. Do not label a cooling-only task as full heating retirement.
Running cost needs local inputs
Use the heat pump running-cost worksheet for a stated period. Demand mode needs delivered heat, COP and backup share. Known-kWh mode prices the supplied metered electricity directly, without a second COP division.
The editable rate references are past US context. Your real tariff and period can differ. Keep fixed fees, cooling and unrecorded other use outside the variable heating subtotal unless they have their own declared records.
A maker's high family HSPF2 does not guarantee a seasonal COP for every house. Use performance data for the exact equipment combination or a clearly labelled range. Do not turn a favorable scenario into a promised saving or deduct future benefits from the current installed subtotal.
Warranty and service terms
Keep the exact supplied parts record and contractor labor terms. A long parts term does not show free future labor or uninterrupted heating. Registration and owner terms need the real records.
Ask who can service the chosen match and what records arrive at start-up checks. Name any retained older unit. A heat-pump warranty does not by itself cover an older furnace used for backup or every existing duct.
No independent failure data is supplied here. Maker records can show features and terms. They do not prove which model will last longest. They do not predict the life of one unit in your home.
More in this guide
Use system choices to compare the five routes with other HVAC options. Keep the house duty the same. The matched-system cost guide explains indoor and outdoor scope. It helps check what the package supplies. It does not accept the actual match on your behalf.
For a furnace fault, use the repair worksheet first. It checks written costs. It does not invent failure odds. A full conversion can be a project goal, but a shortlist does not prove that work is needed.
Keep the shortlisted model tied to one complete proposal
A family can appear in several valid system setups. Keep the real indoor unit, controls and backup with each bid. Do not mix the output curve from one match with the rating of another merely because they share an outdoor family.
If a bidder changes a supplied model, ask for the revised match and work scope. A similar capacity label does not show identical fit or performance. Keep the record date and full suffix so later service and source checks use the correct record.
A room pair and a whole-house ducted package have different planned duties. Compare each with another workable route serving those same duties. Their total-price difference is not a clean equipment premium until room coverage and site work are aligned.
Use the examples to narrow the search. Then ask for a full bid that fits the home. Keep unknown work visible. The largest number on a family page cannot do that job.
FAQ
Which of these heat pumps should I buy?
Use the list to ask for workable bids, not to purchase from a family name. The real load, indoor match and site work come first. Compare equal duties and current source records. The first position does not make Carrier the fixed fit for every house or room.
Are these hands-on test winners?
No. The choice uses source-based maker and official planning research. We did not measure output, sound or long-term failure in homes. Use real certified match records and the written project records for your bid rather than reading editorial segmentation as a test score.
Does a cold-climate product eliminate backup?
Not by label alone. Compare the chosen match's output with the home's load at design conditions. Keep the real backup plan and power scope. A low working limit or capacity-retention claim can be useful evidence. But it does not promise enough heat for every house.
Can a ductless head replace all central heating?
Only a designed coverage plan can show the real duties. A single-zone pair should not be assumed to heat every closed room or floor. Keep room loads, location and backup with the bid. A one-room bid is not equal scope to a full central swap.
Is ground-source COP directly comparable with an air-source winter COP?
Keep the test/source conditions. The systems draw heat from different sources, and the loop has its own design and use duties. A high brochure value is not a common-basis whole-house check. Use full declared working scenarios for real cost research.
Sources and corrections
Current maker records are linked with each choice. Technical planning follows ACCA and ENERGY STAR heat-pump information, checked October 14, 2026. Family claims remain attributed and limited. Real matches need the supplied model records.
The shortlist uses manufacturer records. It does not use copied reviews, star ratings or invented testing. Use contact to report a fix with the full model and source date.
Verdict: shortlist the best heat pumps by the real job
The best heat pumps are stated matches for the planned rooms, climate and service. Start with load and a workable duct network. Then compare current output, scope and terms. Use the heat-pump budget for installed context and the main furnace calculator for an equal-duty option.
