X-Pro 27,000 BTU 2 Zone Mini Split Heat Pump, 24 SEER2, 9K + 18K

A great room with a wall of windows loses and gains heat far faster than a back bedroom. Treat them the same and you either freeze the small room or give up on the big one, usually both in the same week.

This configuration is deliberately uneven: an 18,000 BTU unit for the larger space and a 9,000 BTU unit for the smaller one, both fed by the same 27,000 BTU condenser. Each is sized to its own room instead of splitting one capacity down the middle.

What ships with the system

The carton holds one outdoor condenser, two wall mounted heads, and two 16 ft gas line sets and two 16 ft liquid line sets, two 19 ft communication wires, two drain hoses, two remotes with holders, wall sleeves, caps, tape, putty, screw kits and four mounting foot pads. The outdoor unit measures 38.5" x 16.57" x 31.61" and weighs 119 lb. The indoor units are a 9,000 BTU at 20.7 lb and an 18,000 BTU at 30.9 lb, measuring 32.28" x 7.68" x 12.05" and 43.19" x 8.74" x 13.07".

Capacity, room by room

The 9,000 BTU unit is published for up to 450 sq ft and the 18,000 BTU unit for up to 1,250 sq ft, at 326 and 735 CFM of airflow. Those are the manufacturer's own figures for a room with average ceilings and normal insulation. Natural Resources Canada asks for a recognised load calculation, CSA F280, before equipment is picked, because a leaky 1950s bungalow and a new build of the same floor area do not need the same capacity. Take both numbers to your installer and let the calculation settle it.

How it behaves in a Canadian winter

Heating output on any air source heat pump falls as the outdoor air gets colder. The manufacturer rates this outdoor unit to keep heating down to -25 C (-13 F) and to keep cooling up to 55 C (131 F), and fits a chassis heater that keeps the base pan from icing up. What that figure does not tell you is your balance point, the outdoor temperature below which the heat pump can no longer carry the load on its own. Natural Resources Canada describes that point and the backup heat that takes over below it; your installer works it out for your house.

Quiet running, and how you set it

Both heads are rated as low as 30 dB, with 7 modes (auto, cool, heat, dry, fan, ECO and sleep) and 8 fan speeds from mute to turbo, a 24 hour timer, a child lock, 4D auto swing and a self clean cycle that dries the coil after a run. Filters pull out and wash under the tap. Set it from the wifi app, the remote, or by voice through Alexa or Google Assistant.

Each indoor unit has its own controller and its own target temperature, so one room can sit at 20 C while the other sits at 23 C, from one outdoor unit and one circuit. Both zones share that one compressor: output is divided when they call at once, and the manufacturer does not publish simultaneous heating and cooling for this system, so do not plan on it.

Rated 24 SEER2 for cooling and 10.5 HSPF2 for heating. The compressor ramps its speed up and down to hold a temperature instead of switching hard on and off.

R454B has a global warming potential of 466, roughly a fifth of R410A's 2,088, and is rated A2L for low toxicity and mild flammability.

Rated to keep heating down to -25 C (-13 F) and cooling up to 55 C (131 F). The heated base pan is there to stop meltwater freezing under the coil during a defrost cycle.

Wifi built in, with Alexa and Google Assistant support, a remote for each indoor unit, and a 24 hour timer.

Two 16 ft copper line sets, communication wire, drain hoses and mounting hardware ship with the system. The manufacturer does not publish a maximum line length for this model, so have your installer confirm the runs before the holes are cut.

This is not a plug in appliance. It needs a dedicated 208-230V, 60 Hz circuit and a disconnect at the outdoor unit, wired by an electrician. The indoor units are fed from the outdoor unit, not from separate outlets.

The manufacturer lists this series as Energy Star certified. Certification marks also appear on the specification photo in the gallery.

Ships from a Canadian warehouse. Free shipping on orders over $150; some remote areas, PO boxes and surcharge regions may cost 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.

Older homes on hot water or electric baseboard get cooling and heat pump heating without a duct being cut, since the refrigerant lines need only a small wall penetration.

An 18,000 BTU wall mounted head and a 9,000 BTU wall mounted head let a large open area and a single room each get what they need from one outdoor unit.

Refrigerant work is regulated in every province, and the manufacturer requires a professional technician. This suits buyers who already have an HVAC contractor and an electrician lined up.

What we stand behind

• One outdoor unit, two indoor units and two 16 ft line sets in the box
• Ships from a Canadian warehouse, free shipping over $150
• 14 day returns on unused product in original packaging
• Covered by the manufacturer's warranty for material and manufacturing defects

Can a homeowner install this, or is a licensed installer required?

The manufacturer states that professional installation is required for this system. In Canada, handling refrigerant is regulated province by province, and provinces require trained service providers for installing, servicing and decommissioning equipment that contains halocarbons. Ontario, as one example, restricts removing, discharging and disposing of refrigerants to certified technicians and requires a separate trade Certificate of Qualification to actually work on the equipment. Budget for an HVAC contractor and an electrician.

What electrical supply does it need?

A dedicated 208-230V, 60 Hz circuit, not a wall outlet. On a multi zone system the indoor units are powered from the outdoor unit rather than from their own plugs, and code calls for a disconnect at the outdoor unit. An electrician sizes the breaker and wire from the unit's own nameplate.

What size room does each indoor unit suit?

The manufacturer publishes up to 450 sq ft for the 9,000 BTU unit and up to 1,250 sq ft for the 18,000 BTU unit. Treat those as a starting point. Natural Resources Canada asks for a recognised load calculation such as CSA F280 before equipment is selected, since ceiling height, insulation, air leakage and window area all change the answer for the same floor area.

How well does it heat in a Canadian winter?

The outdoor unit is rated to keep heating down to -25 C (-13 F), and a chassis heater keeps the base pan clear. Output still drops as it gets colder: Natural Resources Canada describes the balance point, the outdoor temperature below which a heat pump can no longer carry the whole load and backup heat takes over. Where that point falls depends on your house, not on the equipment alone, so ask your installer to work it out.
