PTAC AMANA | 12,000 BTUs | HEC (HIGH EFFICIENCY) R410A K
Is it the right size for this room?
Amana doesn't publish a room size for this unit. From its 11,700 BTU/h of cooling, we estimate ≈ 165 to 245 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: 11,700 BTU/h of cooling and a heater of up to 5,000 W when the cold calls for it.
AirGreen estimate: Amana 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
$22.86
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.
≈$163
Heating, all winter
Typical 205 sq ft room with one exterior wall, in Montréal: 1,464 kWh of heat per winter (Environment Canada 1991–2020 climate normals).
≈ $186 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 $14.50.
Capacities and currents: Amana catalog MC-DPTAC 10-23 (October 2023) and manual IO-933A (December 2022). Power draw: 1,026 W in cooling (11,700 BTU/h ÷ EER 11.4), 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.
11,700What it really delivers in cooling
The name says 12,000 BTU: that's the unit's size class. Amana publishes 11,700 BTU/h at 230 V, and 11,400 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
At Amana, the two digits after the series letter (the ** in HEC123K**AXXX) set the heater when ordering: 1.5, 2.5, 3.5 or 5.0 kW at 230 V, 1.3 to 4.1 kW at 208 V. At 5.0 kW it takes a 6-30P plug on 30 A; at 3.5 kW, a 6-20P on 20 A. It heats the room all winter.
11.4Efficiency above the standard model
Amana publishes an EER of 11.4 for this HEC, against 11.0 for the standard PTC of the same size. For the same capacity, it draws fewer watts in summer.
1.7Pints of water it removes per hour
The dehumidification Amana publishes in cooling mode: 1.7 pints per hour. It's what keeps a room comfortable in summer without it turning clammy.
7⅝ inHow far it sticks into the room
Amana quotes a 7⅝ in deep front, one of the slimmest in the industry: the unit takes less space out of the room.
4 °CRoom freeze protection
As soon as the unit senses 40 °F (4 °C) or below, it starts the fan and the heater: an empty room won't freeze in winter.
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.
It fits the standard 42 × 16 in sleeve
Amana sleeves have the industry-standard dimensions: 42 in wide, 16 ¹⁄₁₆ in high, 14 ⅛ in deep. 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.
