A 10,000 BTU through-the-wall air conditioner with heat is the natural size for a large bedroom, a home office, a den or a small living room of about 400 to 450 square feet. At this size, almost every heat model runs on a 230 volt circuit, which lets brands fit a heater as strong as, or stronger than, the cooling section. Our list of the best 10,000 BTU through-the-wall air conditioners with heat compares five of them on heating output, room coverage, noise, sleeve fit and controls. To browse every model we cover, visit our Through-the-Wall Air Conditioners with Heat page.
All five units are rated for rooms up to 450 square feet. The differences come down to heater size, sleeve fit, sound level and whether you want app and voice control.

Other Models Worth Considering
Keystone 10,000 BTU Wall Mounted AC with Heat (KSTAT10-2HD). A 230 volt unit for rooms up to 450 square feet with a 10,600 BTU supplemental heater and up to 2.3 pints per hour of dehumidifying. Its remote measures the temperature where you sit, and Keystone adds 4 years of sealed system coverage on top of 1 year parts and labor. It lists 58 dB and has a 3.5 average from 24 ratings.
LG LT1033HNR 10,000 BTU Through the Wall Air Conditioner with Heat. The quietest unit in this guide at a listed 54 dB, with supplemental heat, 2 cooling, heating and fan speeds, a 24 hour timer and auto restart.

What to Expect from 10,000 BTU Through-the-Wall Air Conditioners with Heat
At 10,000 BTU, heat and cool wall units almost always run on 230 volts, and that extra power means a far stronger heater than small standard outlet models carry. Expect enough heat to warm a medium room on a cool spring or fall day. Most brands still call it supplemental, so pair it with your main heating system in a cold climate.

How to Choose a 10,000 BTU Through-the-Wall Air Conditioner with Heat
Size the Unit to the Room
ENERGY STAR publishes this general guide for sizing a room air conditioner by floor area:
| Room Size (sq ft) | Cooling Capacity (BTU/hr) |
|---|---|
| 100 to 150 | 5,000 |
| 150 to 250 | 6,000 |
| 250 to 300 | 7,000 |
| 300 to 350 | 8,000 |
| 350 to 400 | 9,000 |
| 400 to 450 | 10,000 |
| 450 to 550 | 12,000 |
| 550 to 700 | 14,000 |
| 700 to 1,000 | 18,000 |
Reduce capacity by 10 percent for a heavily shaded room, increase it by 10 percent for a very sunny room, add 600 BTU for each regular occupant beyond two, and add 4,000 BTU if the unit cools a kitchen. Source: ENERGY STAR.
Compare Heater Sizes
Whirlpool, ROVSUN and Keystone list 10,600 BTU of heat on a full 230 volt supply, and TCL lists 9,800 BTU. LG describes its heat as supplemental without a headline figure. If heating matters as much as cooling, look for the higher number, and remember that output drops on a 208 volt supply.
Match the Sleeve
Whirlpool fits sleeves from 24.5 to 27 inches wide, ROVSUN fits a 25.5 inch sleeve, LG and Keystone use a chassis about 24 inches wide, and TCL specifies 26 by 20 by 15.57 inches. Measure the inside of your sleeve before ordering.
Decide on Smart Control
Only the TCL in this guide offers app and voice control. The others use a panel and remote, which is simpler and often cheaper.
