What it does, in numbers
$22.66
Cooling, all summer
Less than a 60 W light bulb
Bulbs left on day and night for a year. Cooling: 5 h a day for 40 days, the assumption used by Hydro-Québec's air-conditioning calculator. Same calculation for every line: wattage × hours × 11.142 ¢/kWh.
≈$143
Heating, all winter
Typical 180 sq ft room with one exterior wall, in Montréal: 1,286 kWh of heat per winter (Environment Canada 1991–2020 climate normals).
≈ $166 for the year, before tax. Winter is 86% of it. If your home stays in the first tier of Rate D in summer (7.065 ¢/kWh), cooling drops to $14.37.
Capacities and currents: Gree PTAC II ETAC2 service manual (R-410A). Power draw: 1,017 W in cooling (11,800 BTU/h ÷ EER 11.6), 5,000 W on the 5 kW heater. Hydro-Québec Rate D in effect since April 1, 2026: 11.142 ¢/kWh second tier, before tax.
What you should know about this one
Published, verifiable facts, not brochure claims.
11,800What it really delivers in cooling
The name says 12,000 BTU: that's the unit's size class. Gree publishes 11,800 BTU/h at 230 V, and 11,600 at 208 V, the supply in many buildings. Better to read it here than on the spec sheet after installation.
5,000 WThe heater that heats the room
Gree publishes a heater of up to 5.0 kW for this model: 5,000 W at 230 V, 4,089 W at 208 V. The size installed follows the power cord (NEMA 6-15P, 6-20P, 6-30P). It heats the room all winter.
50 dBThe noise at low speed
50 dB(A) at low speed, 53 at high speed, as published by Gree. In a bedroom, that's the number that decides the complaints: the unit runs at night, two metres from the bed.
2.75Pints of water it removes per hour
The dehumidification Gree publishes in cooling mode: 2.75 pints per hour. It's what keeps a room comfortable in summer without it turning clammy.
6-30PThe outlet it needs
With the 5.0 kW heater: a NEMA 6-30P plug on a dedicated 30 A circuit. With 3.5 kW: 6-20P on 20 A. With 2.5 kW: 6-15P on 15 A. In a replacement, the outlet already in the wall dictates the heater size.
What it needs on site
In a replacement, we check the outlet and the breaker first: they set the heater size you can use. Our estimator confirms the sleeve, the outlet and the slope before ordering.
