Sized for about the room's square footage at ~20 BTU per sq ft. Rule of thumb: ~20 BTU per sq ft, and 12,000 BTU = 1 ton (this unit is 14,000 BTU). Ceiling height, insulation, sun and climate shift that — if you're between sizes, size up for hot/humid rooms. Not sure? We'll confirm the right BTU for your space.
12,000 BTU = 1 ton — "tons" is just the older way of stating capacity. So 24,000 BTU = 2 tons, 36,000 = 3 tons, and so on. This system is 14,000 BTU. BTU tells you the capacity; SEER2 tells you the efficiency.
It uses R410A — a proven, widely serviced refrigerant. The outdoor unit ships pre-charged for a standard line set, so most installs need no extra refrigerant; your licensed, EPA-608-certified installer verifies the charge and tops it off if your line set is longer.
Runs on 115V — plugs into a standard household circuit, so no special high-voltage wiring is needed in most homes. That makes it easy to add to a bedroom, garage, office or addition without a costly electrical upgrade. Your installer still handles the final hookup and dedicated breaker.
Yes — a big upgrade. It's far more efficient (inverter compressor) and much quieter, since the compressor sits outside instead of in your window or on the floor. It mounts permanently, doesn't block a window, and heats as well as cools year-round. Higher upfront cost, but lower bills and a longer lifespan.
Yes to all three. It's an inverter heat pump — cools in summer, heats in winter (even in the cold), far more efficiently than electric heaters. A Dry mode also pulls out humidity, so rooms feel cooler and less muggy.
Yes — WiFi is included, so you can set schedules, change the temperature, and even turn it on before you get home, all from the mobile app (and pair it with voice assistants). A standard remote is included too.
It should be installed by a licensed, EPA-608-certified HVAC professional — we don't recommend DIY installation. Handling refrigerant requires EPA Section 608 certification under U.S. law, and professional installation keeps the system safe, code-compliant, and your manufacturer warranty valid.
Yes — you get full inverter heat-pump technology and the same core features as premium brands without paying for the name, which is how we keep prices low. Shipping is free on U.S. orders over $300, and our team can help with sizing and support.

Frequently Asked Questions

What size room does it cool?

Up to about 550 sq ft as a guideline. Dual-hose portables cool more effectively than single-hose units of the same rating.

Does it heat too?

Yes — it is a reverse-cycle heat pump (3-in-1: cool, heat, dehumidify) rated 12000 Btu/h heating.

Does it need permanent installation?

No. It rolls on casters and vents through the included window kit — plug into a standard 115V outlet and go. Great for renters and rooms where a wall unit isn't an option.

Single hose or dual hose?

Dual hose (hose-in-hose). Two hoses separate intake and exhaust air, so the unit cools faster and more efficiently and doesn't pull warm unconditioned air back into the room.

What outlet does it need?

A standard 115V / 60Hz household outlet (5-15P (LCDI cord, 15A), 15A). No special wiring.

What's the warranty?

Warranty & Support

Backed by a manufacturer limited warranty — register your unit within 60 days of purchase and keep your receipt. See the included warranty card for full terms. U.S.-based parts and support.
