Ducted vs Ductless Heat Pumps: Which Is Right for Your Canadian Home?
Short answer: if your home already has good ductwork (typically from a forced-air furnace), a ducted (central) heat pump usually makes the most sense and heats the whole house evenly. If you have no ducts (baseboards, boiler, older homes, additions), ductless mini-splits are usually the practical choice. Many rebate programs pay more for ducted or whole-home systems than for a single mini-split. Compare your options in the calculator.
Side-by-side
| Ducted (central) | Ductless mini-split | |
|---|---|---|
| Best for | Homes with existing forced-air ducts | Homes with baseboards, boilers or no ducts; additions |
| How heat is delivered | Through existing vents, whole house | Wall/ceiling heads in each zone |
| Typical installed price | Ducted cold-climate 3 ton: $12,283–$16,618 (QuoteSaver, Sept 2026) | Single zone: $3,500–$7,500 (Jobsite Calcs 2026); 3 zones: $11,433–$15,467 (QuoteSaver) |
| Whole-home heating | Yes, if sized correctly | Needs several heads; open layouts help |
| Looks | Hidden indoors | Visible indoor heads |
| Backup heat | Electric strips or furnace (hybrid) | Usually existing baseboards |
| Room-by-room control | Limited unless zoned | Excellent |

How rebates treat each type
Rebate amounts often depend on system type. Examples from official program pages:
| Province | Ducted | Ductless |
|---|---|---|
| Manitoba | $2,000 (centrally ducted ccASHP) | $1,500 (ductless ccASHP) |
| New Brunswick | $1,500 central ducted | $400 mini-split; $350 per indoor head multizone |
| Nova Scotia | $500/ton (HEA); $1,500/ton extra with Moderate Income Rebate | $300/ton (HEA); $500/ton extra with Moderate Income Rebate |
| British Columbia | Up to $13,000 for central ducted or 3-head multi-split (Income Level 1) | Lower for 2-head systems |
| Ontario | $1,250/ton up to $7,500 (non-gas homes), ducted or ductless | Same per-ton rate |
| Quebec | $120 per 1,000 BTU/h at -8°C (cold climate), any type | Same |
| Newfoundland and Labrador | Whole-home heating required for Oil to Electric | Single mini-split rarely qualifies |
Federal National Heat Pump Rebate: the announcement covers "electric cold climate air source heat pumps" on its Eligible Products List and mentions "various price points and configurations." Whether ductless and ducted are treated differently is not yet published.
When ducted is the better choice
- You have a forced-air furnace with ducts in good shape.
- Your furnace just died and you want one replacement that heats the whole house. See furnace died?
- You want central air conditioning too.
- Your program pays more for whole-home or ducted systems (BC, Manitoba, New Brunswick).
Check: ducts sized for a furnace sometimes need modifications, because heat pumps deliver air at lower temperatures and higher airflow. Ask the installer to check static pressure and airflow.
When ductless is the better choice
- Your home is heated by baseboards, a boiler or wood.
- You want to heat a specific area (basement suite, addition).
- Installing ducts would mean opening walls and ceilings. HomeStars reports $15,000–$25,000 for a heat pump with full new ductwork in a finished home.
- Ontario, where the rebate is per ton for both types.
Check: one head rarely heats a whole house. Bedrooms behind closed doors may stay cooler. NL's program notes that less than 1% of homes can get whole-home heating from a single mini-split.
Mixed and hybrid setups
- Multi-split: one outdoor unit feeding several heads.
- Ducted mini (short-run ducts): concealed air handlers serving a few rooms.
- Hybrid / dual-fuel: a ducted heat pump plus the existing gas furnace as backup. Check whether your program allows it.
Whole-home vs partial-home rules
Several programs pay differently depending on whether the system heats the whole home:
| Program | Whole-home | Partial |
|---|---|---|
| BC Hydro (electric-heated homes) | $4,000: must meet 100% of heating needs at -5°C | $1,500: must meet 50% or more |
| takeCHARGE NL Oil to Electric | Whole-home heating required | Not eligible |
| Edmonton CEIP | Must meet ≥ 50% of designed heating load | — |
| CleanBC ESP | Highest tier for central ducted or 3+ head multi-split | 2-head systems get less |
In practice, a single ductless head usually counts as "partial" heating. Ducted systems or multi-head ductless setups are more likely to hit whole-home rules.
Installation and comfort details
- Line sets and outdoor unit placement: ductless runs refrigerant lines to each head. Longer runs and wall penetrations add cost.
- Air handler: a ducted heat pump replaces or pairs with your furnace's blower. Ask whether the existing furnace stays as backup (hybrid) or is removed.
- Ducts in unconditioned spaces: Efficiency Nova Scotia excludes heat pump equipment installed in unconditioned space (such as ductwork through attics) from its rebates.
- Zoning: ductless gives room-by-room control by default. Ducted systems need dampers and zone controls for the same effect.
- Noise: Ottawa's ground-source incentive requires 55 dB or less in cooling. Check sound ratings for any outdoor unit near bedrooms or neighbours.
Cost per zone vs whole home
| Setup | Typical installed range | Source |
|---|---|---|
| 1 ductless zone | $3,500–$7,500 | Jobsite Calcs |
| 2–3 ductless zones | $6,000–$12,000 | Jobsite Calcs |
| 3 ductless zones | $11,433–$15,467 | QuoteSaver |
| 3–4 room multi-zone | $12,000–$22,000 | Greenfoot |
| Ducted cold-climate, 2 ton | $11,008–$14,892 | QuoteSaver |
| Ducted cold-climate, 4 ton premium | $15,258–$20,643 | QuoteSaver |

FAQ
Are ductless heat pumps cheaper?
Per zone, yes. A whole house of ductless heads can cost as much as a ducted system, according to 2026 price guides.
Which works better in the cold?
Both come in cold-climate versions. Performance depends on the specific model's capacity at low temperatures. See heat pumps at -30°C.
Does the federal rebate cover mini-splits?
The program covers eligible cold-climate air-source heat pumps on its Eligible Products List. Configuration-specific rules are not yet published.
