X-Pro 27,000 BTU 3 Zone Mini Split Heat Pump, 24 SEER2, Wifi, 12K + 12K + 12K

A single thermostat averages the whole house and reads one room. Somebody is always too warm or too cold. Closing vents to rebalance a room just moves the problem somewhere else and strains the blower.

Three zones measure and correct their own space. The 12,000 BTU unit can hold one room cool while the 12,000 BTU unit heats another, and both report back to the same 27,000 BTU outdoor unit without fighting each other.

One outdoor unit, three indoor units

The photo has the complete system in it: a 27,000 BTU condenser for outside, three wall units of 12,000, 12,000 and 12,000 BTU for inside, three remotes and the copper, wire and sundries that connect them. Nothing here is sold separately as an accessory pack.

Phone, remote or voice

The system connects to wifi, so each zone can be checked and changed from the app while you are out. It also answers to Amazon Alexa and Google Home, and every indoor unit still ships with a physical remote for anyone who would rather press a button.

Noise, measured rather than described

The photo puts numbers on it: around 50 dB at the top end, 40 dB in the middle, and as low as 30 dB on the mute setting. That bottom figure is the one that matters in a bedroom, and it is why the fan has eight speeds rather than three.

Mapping the three zones

This floor plan view shows how a three zone layout usually lands: a main living space, a bedroom and a third room, each with its own indoor unit and its own number. The single outdoor unit sits on a pad or a bracket outside and serves all three.

One 27,000 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). Each 12,000 BTU unit suits roughly 480 to 600 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 24 SEER2 for cooling and 10.5 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 55°C (131°F).

Each zone gets a 16 ft insulated copper line set and 19 ft of communication wire. That is the material most quotes list separately.

The outdoor unit runs on 208-230V 60Hz. 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, a remote with a digital display for each zone, Amazon Alexa and Google Home.

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.

Ships from a Canadian warehouse. Free shipping on orders over $150. Some remote areas, PO boxes and surcharge regions may be excluded or charged extra.

Return within 14 days of purchase, unused, in original condition and packaging.

Covered directly by the manufacturer under their warranty terms for material and manufacturing defects.

All three units are 12,000 BTU, so this suits three comparable spaces of roughly 480 to 600 sq ft each: bedrooms, a home office, a finished basement room.

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 10.5 and a chassis heater for winter operation.

• Line sets, communication wire and a controller for every zone are in the box

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. Each 12,000 BTU unit suits roughly 480 to 600 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 36,000 BTU but the outdoor unit is 27,000 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 27,000 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 power supply also means an electrician and a dedicated circuit.
