PTAC : Friedrich | AC 12 000 BTU | Montreal, Laval, Longueuil, South Shore and North Shore
Is it the right size for this room?
Friedrich doesn't publish a room size for this unit. From its 11,800 BTU/h of cooling, we estimate ≈ 165 to 250 sq ft. Choose your room's area.
It's the right size.
For a 175 to 225 sq ft room, this is the range we estimate for this unit: 11,800 BTU/h of cooling and a heater of up to 3,450 W when the cold calls for it.
AirGreen estimate: Friedrich publishes no room size, so we apply the application ranges Trane publishes for its PTACs of the same cooling capacity. Our estimator confirms the exact area on site.
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.
≈$165
Heating, all winter
Typical 208 sq ft room with one exterior wall, in Montréal: 1,482 kWh of heat per winter (Environment Canada 1991–2020 climate normals).
≈ $188 for the year, before tax. Winter is 88% 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: Friedrich ZoneAire Premier product profile PP_PTACPRE_2023 (rev. 2-20-23) and installation manual 9830 1000_00. Power draw: 1,017 W in cooling (11,800 BTU/h ÷ EER 11.6), 3,450 W on the 3.5 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. Friedrich 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.
3,450 WThe heater that heats the room
The "3" in PDE12K3SG sets the heater at 3.5 kW: 3,450 W and 11,700 BTU/h at 230 V, 2,821 W at 208 V, on a 6-20P plug and a 20 A circuit. It heats the room all winter.
2.7Pints of water it removes per hour
The dehumidification Friedrich publishes in cooling mode: 2.7 pints per hour. It's what keeps a room comfortable in summer without it turning clammy.
75 cfmFresh air through the vent door
The vent door brings in up to 75 cfm of outside air, according to Friedrich. Close it to keep all the heat or the cool air in the room.
6-20PThe outlet it needs
This model plugs into a NEMA 6-20P outlet on a dedicated 20 A circuit. In a replacement, we first check the outlet and breaker already in place.
It fits a standard PTAC sleeve, with no baffle kit
Friedrich designs this PTAC for the standard 42 × 16 in sleeve, without the added cost of a baffle kit. Our estimator checks the sleeve and the grille in place before ordering.
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.
