Which Heat Pump Is Right for You?
Eight heat pump system types compared. Each has trade-offs in cost, efficiency, and installation complexity.
Which type is right for you?
Does your home have existing ductwork?
What is your winter climate like?
What do you currently heat with?
Mini-Split (Ductless)
$3,000 – $8,000How It Works
An outdoor compressor connects to one or more indoor wall-mounted units via refrigerant lines. Each indoor unit heats or cools a single zone independently.
Best For
Homes without ductwork, additions, converted garages, single-room heating/cooling, or supplementing an existing system.
Pros
- + No ductwork required — lower install cost
- + Zone-by-zone temperature control
- + Highly efficient (SEER2 up to 30+)
- + Quiet operation
Cons
- – Visible wall units in each room
- – Multi-zone systems get expensive
- – Not ideal for whole-home heating in cold climates without multiple heads
Central Ducted Air Source
$5,000 – $12,000How It Works
An outdoor heat pump unit connects to an indoor air handler that distributes conditioned air through your existing ductwork — same concept as a central AC, but it heats and cools.
Best For
Homes with existing ductwork that want to replace a furnace + AC with a single system.
Pros
- + Uses existing ductwork — clean whole-home solution
- + One thermostat, familiar operation
- + Replaces both furnace and AC
Cons
- – Requires existing ductwork in good condition
- – Duct losses reduce efficiency (10–30%)
- – May need supplemental heat in extreme cold
Cold Climate ASHP
$4,000 – $10,000How It Works
Engineered with enhanced vapor injection (EVI) compressors to maintain heating output at temperatures as low as -15°F (-26°C). Available in both ducted and ductless configurations.
Best For
Homes in IECC Climate Zones 5–7, regions with extended below-zero winters, or anywhere temperatures regularly drop below 5°F (-15°C).
Pros
- + Rated heating capacity to -15°F (-26°C)
- + Eligible for federal and state cold-climate incentives
- + Can eliminate fossil fuel backup in many climates
Cons
- – Higher equipment cost vs standard ASHP
- – Capacity still drops in extreme cold (supplemental heat may be needed below -15°F)
- – Fewer model options than standard heat pumps
Ground Source (Geothermal)
$15,000 – $30,000How It Works
A ground loop (buried pipes) circulates fluid that absorbs heat from the earth in winter and rejects heat in summer. The heat pump inside moves that energy into your home.
Best For
Homeowners planning to stay 15+ years, new construction with open land, or anyone who wants maximum efficiency regardless of upfront cost.
Pros
- + Highest efficiency of any heat pump type (COP 4–5)
- + Works in any climate — ground temp is constant
- + 25+ year ground loop lifespan
- + Eligible for 30% IRA tax credit (no cap)
Cons
- – High upfront cost — ground loop installation is expensive
- – Requires land for horizontal loops or drilling for vertical
- – Not practical for small lots or dense urban areas
Hybrid (Dual Fuel)
$4,000 – $9,000 (heat pump only, paired with existing furnace)How It Works
A heat pump handles heating above a set outdoor temperature (typically 25–35°F). Below that switchover point, a gas furnace takes over. The thermostat switches automatically.
Best For
Homes with an existing gas furnace in good condition, cold climates where full electrification is not yet cost-effective, or areas with low natural gas prices.
Pros
- + Lower operating cost than gas-only or heat-pump-only in extreme cold
- + Uses existing furnace as backup — lower install cost
- + Reduces gas consumption by 50–80%
Cons
- – Still uses fossil fuel — not fully electric
- – Requires maintaining two systems
- – May not qualify for electrification-only rebates
Air-to-Water (Hydronic)
$8,000 – $25,000How It Works
An outdoor heat pump unit heats water in a closed loop. That hot water circulates through radiators, radiant floor tubing, or fan coil units — replacing the hot water your gas or oil boiler produced.
Best For
Homes with existing hydronic heating (radiators, radiant floor), or oil/gas boiler replacements. Common in Atlantic Canada, Quebec, New England, and the US Northeast.
Pros
- + Works with existing boiler piping and radiators
- + Cold-climate models rated to -25°C / -13°F
- + Higher comfort than forced air in many homes
- + Eliminates oil or gas boiler entirely
Cons
- – Higher cost than air-to-air systems
- – Fewer qualified installers than standard ASHP
- – Older radiators may need upsizing for low-temperature operation
- – Buffer tank requires mechanical room space
Oil-to-Heat-Pump Conversion
$5,000 – $15,000 (before rebates of up to $10,000)How It Works
Replacing an oil furnace or boiler with a cold-climate ASHP. Includes oil tank decommissioning, electrical panel assessment, and installation of a ducted or ductless cold-climate heat pump.
Best For
Atlantic Canada, Quebec, and US Northeast (ME, VT, NH, MA, NY) where oil is the dominant heating fuel. Large rebate programs specifically target oil displacement.
Pros
- + Eliminates volatile oil fuel costs — savings of $1,500–$3,000/year typical
- + Aggressive rebates in Atlantic Canada and US Northeast
- + 3–7 year payback period after rebates
- + Cold-climate ASHP works to -25°C / -13°F
Cons
- – Panel upgrade often required (100A → 200A)
- – Underground oil tank removal adds cost and complexity
- – Installer must handle both HVAC and electrical work
