X-Pro 35,000 BTU 3 Zone Ducted Mini Split Heat Pump, 22.5 SEER2, Wifi, 12K + 12K + 12K

A single thermostat reads one room and averages the rest. Closing vents to rebalance a space just moves the problem and strains the blower. Somebody is always adjusting it and somebody else is always changing it back.

Three zones, three wall thermostats, three set points. The 12,000 BTU handler can cool one space while the 12,000 BTU handler heats another, both drawing from the same 35,000 BTU outdoor unit.

Three air handlers and one condenser

Everything in the photo ships together: the 35,000 BTU outdoor unit, three ducted air handlers of 12,000, 12,000 and 12,000 BTU, the copper line sets and a thermostat per zone. Each handler feeds its own short duct runs, so the 12,000 BTU zone can run while the other two sit idle.

Line sets included, not quoted separately

On a lot of multi-zone quotes the copper is a line item. Here each zone arrives with its own 16 ft insulated line set and 19 ft of communication wire, along with sleeves, caps, screws, putty and tape. Three wall thermostats are in the box as well, one per zone.

What happens when it gets properly cold

The outdoor unit carries a chassis electrical heater, which keeps the base pan clear so meltwater does not freeze under the coil. The manufacturer rates heating down to -25°C (-13°F) and cooling up to 55°C (131°F). Natural Resources Canada notes most air source heat pumps stop somewhere between -15°C and -25°C, so plan on a backup heat source for the coldest nights.

Reading the yellow label

The EnergyGuide panel in this photo is the honest summary: 22.5 SEER2 on cooling, 10 HSPF2 on heating, with R454B refrigerant in the system. The graph beside it shows why an inverter holds temperature better than a fixed-speed compressor that only knows on and off. It carries ETL and AHRI certification.

One 35,000 BTU outdoor unit runs all three ducted air handlers. 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 22.5 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 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.

A wall thermostat for each zone, plus a handheld remote, the phone app, Amazon Alexa and Google Home.

The air handlers sit above a ceiling or inside a bulkhead and feed short duct runs to grilles. Only the supply and return grilles are visible in the room.

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.

Tall-window living rooms, heritage interiors, offices and dining rooms all look better without a unit on the wall. The handler hides in a ceiling void and only the grilles are visible.

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. 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 35,000 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 35,000 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.
