A fixed speed compressor runs flat out until the room passes the set point, then stops until it drifts back. The result is a room that cycles between too cold and too warm, and a machine that is loudest exactly when you notice it.

The inverter compressor varies its speed instead of switching on and off, so it settles at whatever output holds the temperature. That is what gives it a CEER of 10 against the 6.2 to 8 typical of the fixed speed units in this range.

Why the CEER figure is so much higher

CEER 10 on R32 refrigerant with a dual motor design. Most floor standing portables in this catalogue rate between 6.2 and 8. The inverter is the reason: it holds a steady output instead of slamming between full power and nothing, which wastes less at every cycle.

Two seasons, two coverage figures

15,000 BTU of cooling across up to 750 sq ft, and 10,300 BTU of heating across up to 450 sq ft. Heating always covers less area than cooling on a machine like this, and the manufacturer states both figures rather than quoting one and leaving you to guess.

The parts that make a 63 lb machine liveable

Two handles recessed into the cabinet, four wheels that turn through a full circle, a winder for the 5.9 ft cord and filters that pull out for rinsing. The louvre sweeps 80 degrees, which is the widest powered swing in this range.

Set from the sofa or from the office

Wifi control through the app sits alongside a touch panel and a remote that reaches 26 ft. The panel carries swing, timer, speed, the arrows, mode, sleep, power and a wifi key of its own, so the connection can be turned off if you would rather not use it.

Varies its speed instead of cycling on and off, which holds a steadier temperature and wastes less.

Well above the 6.2 to 8 typical of fixed speed portables in this range.

15,000 BTU of cooling to 750 sq ft and 10,300 BTU of heating to 450 sq ft.

One of the highest dehumidifying rates in this catalogue, with a 39.5 inch drain hose supplied.

Low for a 15,000 BTU machine, helped by the compressor running at part speed most of the time.

The widest powered sweep in this range, which suits a large open room.

A CEER of 10 against the 6.2 to 8 typical of fixed speed portables changes what it costs to run over several summers, not just one.

Cools up to 750 sq ft and heats up to 450 sq ft, so one machine covers a den, a studio or a garage office from spring to autumn.

A variable speed compressor settles at the output the room needs instead of alternating between full power and silence.

What does an inverter compressor actually change?

A fixed speed compressor is either on at full power or off. An inverter varies its speed and settles at whatever output holds the set temperature. That means a steadier room, less noise at the top end and less electricity wasted restarting, which is why this unit rates CEER 10 where fixed speed portables in the same range sit between 6.2 and 8.

Does it need a special circuit?

It runs on a standard 115V, 60Hz household socket, but it draws 12 A while cooling. That is close to the continuous limit of an ordinary 15 amp circuit, so plug it directly into a wall outlet of its own and do not share the circuit with a kettle, a heater or a second air conditioner.

How much heating does it give?

10,300 BTU, rated for up to 450 sq ft. That is enough to take the chill off a den, a studio or a garage office in spring and autumn. It is not a furnace and it is not intended to carry a room through a Canadian winter.

What does the CSA mark mean?

CSA is a Canadian safety certification, published by the manufacturer for this model alongside DOE. It is the mark most Canadian buyers look for on an electrical appliance, and it is worth noting that not every unit in this category carries it.
