Ducted or ductless heat pump for your Greater Victoria house?

Start with the house, not the catalogue

Greater Victoria's housing stock sorts into a few recognizable groups, and the group your house belongs to usually settles the question before an installer walks in. The older core, meaning James Bay, Fairfield, Fernwood, Vic West, most of Oak Bay and Esquimalt and pre-war Saanich, was built with oil furnaces, hot-water radiators or, after the 1950s, electric baseboards; many of those houses have never had a duct in them. The 1960s-to-1980s suburbs, Gordon Head, Broadmead, Royal Oak, Brentwood Bay and older Colwood, split between baseboards and forced-air furnaces, and where the furnace exists the ducts exist and their condition is the question.

The newer Westshore, meaning most of Langford, Westhills, Bear Mountain, Royal Bay and newer Sooke subdivisions, was largely built with a ducted electric furnace and a 200 A panel. Those are the region's natural central ducted candidates, and where the whole-home electric rebate tier is most straightforward.

Central ducted: when it fits and what to check

A central ducted heat pump replaces the furnace with an air handler and puts the heat pump coil in the airstream, so every register gets heating in winter and cooling in summer. On existing ducts our estimate is $12,000–$22,000our estimate. It keeps the walls clear of indoor heads, gives you one thermostat, and filters all the air in the house through one rack, which matters on smoke days.

The catch is the ducts. Heat pump supply air is cooler than furnace air, so the system moves more of it; leaky, kinked or undersized ducts a furnace could overpower become whistling registers and a lukewarm back bedroom. Ask the installer to inspect the ducts and say in writing whether they are adequate; sealing or partial repair is a common add-on with no verified local figure, so get it as a separate line. A ducted system also gives one temperature for the whole house; if the upstairs bakes and the basement suite freezes today, the heat pump alone will not fix that.

Ductless: what it is good at and where it disappoints

A ductless system pairs an outdoor unit with one or more indoor heads, each heating and cooling the space it sits in. For an open-plan main floor with baseboards, one head near the living area covers most daily comfort for about $4,500–$8,500our estimate, and each head has its own temperature.

Where it disappoints is the closed-room house. Heat does not turn corners well, so a hallway head leaves bedrooms cool with the doors shut. The fixes are more heads, baseboards kept in the bedrooms as supplemental heat, or a slim-duct unit in the attic feeding two or three small rooms. Local homeowners put it bluntly: 'every room is a room with a door, so switching to mini-splits is impractical.' Each head also needs a condensate drain or pump, and the line set runs along the exterior wall in a cover, which matters to strata councils and to anyone who cares how the front of the house looks.

Can ductless heat the whole house, and how many heads?

Yes, and many Victoria homes with no ducts run entirely on it. The number of heads follows the layout, not the square footage: count the spaces that need their own temperature and that air cannot reach from another head. A bungalow usually ends up with a head in the main living area and one in each bedroom that must be warm with the door shut; a two-storey home needs at least one per floor plus bedrooms. For the whole-home rebate tier the system must meet the full load at −5 °C with no resistance backup, verified by a load calculation, which usually means a head in every room with a door.

There are two ways to build it. One outdoor unit feeding several heads (a multi-split) is tidier outside and cheaper per head, but it has a minimum output and on a mild October day with one head calling it may cycle rather than modulate. Separate single-zone systems cost more and put more cabinets outside, but each modulates on its own and a failure takes out one room. Noise bylaws and setbacks in Saanich, Oak Bay, Sidney and Central Saanich can limit how many outdoor units you can place.
