Attic conversions, finished basements, additions and garages often have no ductwork at all. Extending ducts means opening ceilings and walls. Portable units need a hose out a window and have to be stored every autumn.

Each zone needs one cored hole for the copper line set, communication wire and drain, not a duct run. This kit ships with a 16 ft line set, 13 ft of wire and a controller per zone, sized at 7,000, 7,000 and 24,000 BTU.

Everything that comes on the pallet

Laid out here is the whole kit: the 30,000 BTU outdoor unit, three white indoor units rated 7,000, 7,000 and 24,000 BTU, a remote for each one, the insulated copper line sets and the tape, putty and wiring that join them up. Each indoor unit answers to its own remote, so the 24,000 BTU unit can run hard while the other two idle.

January on the north side of the house

Frozen meltwater in the base pan is what kills an outdoor unit in a Canadian winter. A chassis heating element in this one keeps that pan clear. Rated limits are -25°C (-13°F) for heating and 52°C (125°F) for cooling, and output falls as it gets colder, so keep a second heat source for deep cold.

Sleeping in the same room as it

Sleep mode eases the set point overnight, the display can be switched off so nothing glows at you, and the 24 hour timer can shut a zone down after you drop off. The 7,000 BTU unit is rated 30 dB indoors. A quiet library sits around 40 dB for comparison.

Where the 23 SEER2 number comes from

Inverter compressors ramp up and down instead of slamming on and off, which is what holds a room steady and keeps the meter from spiking. The EnergyGuide panel on this outdoor unit shows 23 SEER2 for cooling and 10 HSPF2 for heating, and the refrigerant is R32. It carries ENERGY STAR, ETL and AHRI certification.

One 30,000 BTU outdoor unit runs all three indoor units. Each zone starts, stops and holds its own temperature, so an empty room costs nothing.

A common rule of thumb is 20 to 25 BTU per square foot (Carrier publishes 25). Here, a 7,000 BTU unit suits roughly 280 to 350 sq ft and a 24,000 BTU unit suits roughly 960 to 1,200 sq ft. Natural Resources Canada points to CSA F280-12 for a proper load calculation.

The compressor varies its speed instead of cycling on and off. Published ratings are 23 SEER2 for cooling and 10 HSPF2 for heating.

A chassis electrical heater keeps the outdoor base pan clear. The manufacturer rates heating down to -25°C (-13°F) and cooling up to 52°C (125°F).

Each zone gets a 16 ft insulated copper line set and 13 ft of communication wire, plus a 6.5 ft drain hose. That is the material most quotes list separately.

The outdoor unit runs on 208-230V~60Hz, single phase. It wants its own branch circuit, sized from the MCA and maximum breaker figures on the unit's own nameplate, with a disconnect within reach.

Wifi app plus a remote with a digital display for each zone, and a 24 hour timer.

The indoor filters pull out, rinse under a tap and go back in. Clean filters are the cheapest way to keep airflow and running cost where they should be.

The 24,000 BTU unit is sized for an open living and dining space, roughly 960 to 1,200 sq ft. The other two zones cover normal bedrooms without oversizing them.

Older houses, additions, attic conversions and finished basements rarely have ducts where they are needed. Three zones from one outdoor unit avoids opening up ceilings.

This is a heat pump, not a cooling-only air conditioner. It carries an HSPF2 heating rating of 10 and a chassis heater for winter operation.

How much space will each indoor unit cover?

Sizing runs off the heat load of the room, not just its floor area, and Natural Resources Canada points to CSA F280-12 for the real calculation. As a rough check, 20 to 25 BTU per square foot is the usual rule of thumb. Here, a 7,000 BTU unit suits roughly 280 to 350 sq ft and a 24,000 BTU unit suits roughly 960 to 1,200 sq ft. Poor insulation, big west-facing windows or a 9 ft ceiling all push that figure up.

The three indoor units add up to 38,000 BTU but the outdoor unit is 30,000 BTU. Is that a mistake?

No. On any multi-zone system the indoor ratings are not meant to be added together, and sizing guides for multi-zone equipment say so plainly. The 30,000 BTU figure is what the outdoor unit can deliver at one time, and it is shared among whichever zones are calling for it. Three rooms rarely peak at the same moment, which is why this combination is offered.

How cold can it get outside before it stops heating?

The manufacturer rates low ambient heating down to -25°C (-13°F), helped by an electric heater in the outdoor chassis. Natural Resources Canada notes that air source heat pumps lose capacity and efficiency as it gets colder, with typical COPs falling from 2.0 to 5.4 at 8°C to 1.1 to 3.7 at -8°C, and that most units have a minimum operating temperature between -15°C and -25°C. Keep a backup heat source for the coldest stretches.

Can I install this myself in Canada?

Plan on a licensed installer. In Ontario, for example, the province states that by law only a certified technician may remove, discharge, handle and dispose of refrigerants, including HFCs, and that mechanical work on refrigeration equipment needs a Certificate of Qualification on top of the refrigerant certificate. Other provinces have their own halocarbon rules. The federal Code of Practice says the same thing in plainer terms: the technician doing work that could release refrigerant must hold the proper environmental certification. The 208-230V~60Hz, single phase power supply also means an electrician and a dedicated circuit.
