Midea is known in the room air conditioner category for inverter units that run quietly and use less electricity than older on-off designs, along with unusual shapes such as the U-shaped window AC and the Duo portable with its hose-inside-a-hose. If you searched for a Midea 12,000 BTU unit with heat, here is the most important point first: only two of the five models below list a heating function, the 12,000 BTU Window Air Conditioner with Heat and the Duo 14,000 BTU Portable. The other three are listed as cooling units, and we say so plainly in each section.
These five models differ in whether they heat, whether they sit in a window or roll on the floor, and how large a room their rated cooling actually covers.

Two terms explained simply. BTU (British thermal unit) measures how much heat an air conditioner can move out of a room each hour, so a bigger number means more cooling. Portable ACs often show two numbers: the ASHRAE rating and a lower SACC rating, which accounts for real-world losses. That is why three “12,000 BTU” units here cover very different room sizes. An inverter means the compressor speeds up and slows down smoothly instead of switching fully on and off, which saves energy and reduces noise.
Midea 12,000 BTU Window Air Conditioner with Heat for Large Rooms
The Midea 12,000 BTU Window Air Conditioner is the most direct answer to the search. It cools, dehumidifies and provides supplemental heat through a heat pump, for rooms up to 550 square feet. The listing is clear about one limit: the heat pump will not work when the outside temperature is 41°F or below. That makes it a spring and fall heater, not a replacement for winter heating in cold climates.
It is Energy Star certified and UL Listed, uses inverter technology with a CEER of 13.3 and claims up to 35% energy savings compared to the Energy Conservation Standard. Noise can drop as low as 45 dBA. Controls include a digital LED display, five modes (Heat, Auto, Cool, Dry, Fan), a 24-hour timer, an ECO setting, a Swing button for the louvers and wireless control from a phone. The feature list says 3 speed settings while the description says 4 (Auto, High, Medium, Low), so the listing is inconsistent on that point. It runs on 115V, uses R-32 refrigerant and has a washable filter.
It fits double-hung windows 24 to 38.5 inches wide with a clear vertical opening of at least 14.5 inches, and measures 19.41 by 22.17 by 13.9 inches. Choose it if you have a suitable window and want both cooling and mild-weather heat. We cover this exact unit in our Midea window AC with heat review.
Midea Duo 14,000 BTU Portable Air Conditioner for Portable Heat and Cooling
Midea
Midea Duo 14,000 BTU Portable Air Conditioner with Heat, Inverter Quiet

Midea Duo 14,000 BTU Portable Air
Best for: Renters needing portable heat and cooling
Pros
- Heat pump, 41-86°F range
- Dual hose-in-hose design
- As low as 42 dB
- App and voice control
Cons
- Heavy at 77.2 pounds
- Listing color is inconsistent
The Midea Duo 14,000 BTU Portable Air is the portable answer to the “with heat” request. Its listing names heating as well as cooling, with a heat pump operating range of 41°F to 86°F. The description gives it 14,000 BTU on the ASHRAE scale and 12,000 BTU SACC, for spaces up to 550 square feet, so its real-world cooling matches the window model above.
The Duo name comes from its dual hose-in-hose design: one hose inside another pulls air in from outdoors and pushes hot air out, which the listing says keeps hot outside air from seeping in through gaps. It uses variable-speed inverter technology, claims more than 40% energy savings compared to the U.S. federal standard, runs as low as 42 dB and supports the SmartHome app plus Alexa and Google Assistant. The remote needs two AAA batteries. It measures 16.73 by 19.53 by 34.48 inches and weighs 77.2 pounds, and the color field says black while the description says white, so check the product box.
It suits renters or anyone whose windows cannot hold a window unit, provided they can handle a heavy floor unit. It gives way to the window model if you want to keep floor space free.
Midea 12,000 BTU U Shaped Window Air Conditioner for Quiet Bedrooms
The Midea 12,000 BTU U Shaped Window is a cooling unit, and its listing does not mention a heat mode. We include it because it is one of Midea’s best-known 12,000 BTU models, but if heat is a must, pick one of the two models above.
Its U shape sits over the window sash, so the window blocks outside noise and can still open for fresh air. The listing claims operation as low as 32 dBA, nine times quieter than traditional units, more than 37% energy savings from its DC inverter, and says it was the first window AC to earn Energy Star certification. It has Wi-Fi, app and voice control, an anti-theft mechanism that locks the window when closed, and a quick-snap bracket for installation. It fits single-hung or double-hung windows 22 to 36 inches wide with a minimum height of 13.75 inches, cools up to 550 square feet and draws 1140 watts.
This is the quietest model in the list and a strong choice for a bedroom where summer cooling is all that is needed. Our broader Midea 12000 BTU guide compares more models of this size.
Midea Duo 12,000 BTU Portable Air Conditioner for Mid-Size Rooms

Midea Duo 12,000 BTU Portable Air
Best for: Portable cooling where windows won’t fit units
Pros
- Dual hose-in-hose design
- As low as 42 dB
- Wi-Fi and voice control
Cons
- Listing names no heat mode
- 10,000 BTU SACC rating
The Midea Duo 12,000 BTU Portable Air shares the dual hose-in-hose design, inverter technology, more than 40% energy savings claim and 42 dB low noise of the larger Duo. The listing does not mention a heat function, so treat it as a cooling-only portable.
Its description rates it at 12,000 BTU ASHRAE and 10,000 BTU SACC for spaces up to 450 square feet. It has Wi-Fi with the SmartHome app, Alexa and Google Assistant support, a dust filter and an air fresh filter, air throw up to 26 feet and a 102-degree cool swing. It uses R-410A refrigerant and comes in black.
It suits someone who needs a portable for a medium room in summer only. If you want heat as well, the Duo 14,000 BTU is the version to choose.
Midea 12,000 BTU ASHRAE Inverter Portable for Small Rooms
The Midea 12,000 BTU ASHRAE Inverter Portable is the smallest performer here despite the 12,000 BTU headline. Its SACC rating is 8,000 BTU, for spaces up to 350 square feet. It offers cooling, fan and dehumidification functions; the listing does not name a heat mode.
It has an inverter compressor with a claim of more than 66% energy savings versus the U.S. federal standard, Wi-Fi app control including smartwatch control, Alexa and Google Assistant support, an LED display, a 24-hour timer and a temperature range of 62 to 90°F. The remote uses AAA batteries (included) and has a proximity sensing feature. A removable, reusable filter comes with a cleaning reminder light, and the exhaust hose and window kit are included. The spec table lists 12000 watts, which looks like a data error because it copies the BTU number; the listing does not give a reliable wattage.
It fits a small bedroom or home office in summer. For heat, look back at the Duo 14,000 BTU.
How to Choose the Right Midea Air Conditioner with Heat
Confirm the heat. Only the Window AC with Heat and the Duo 14,000 BTU list heating. Both use heat pumps, which lose effectiveness in cold weather: the window model stops at 41°F outside, and the Duo lists a 41-86°F range. If you want to understand this in more depth, read our Midea heat pump explainer.
Window or portable. Window units free up floor space and tend to be efficient. Portables suit rentals or windows that cannot hold a unit, but they need a hose and floor space.
Read the SACC number. For portables, SACC reflects real cooling. The three 12,000 BTU labels here range from 12,000 SACC (Duo 14,000) to 8,000 SACC (ASHRAE Inverter Portable).
Noise. The U Shaped Window is the quietest at 32 dBA; the others range from 42 to 48 dB.
FAQ
Which Midea 12,000 BTU unit has heat?
The Midea 12,000 BTU Window Air Conditioner with Heat. Among portables, the Duo 14,000 BTU (12,000 BTU SACC) also heats.
Will the heat work in winter?
Only in mild weather. The window model’s heat pump does not operate at 41°F or below outside, so it is meant as supplemental heat.
Does the Midea U shaped window air conditioner heat?
Its listing does not mention a heat mode, so treat it as cooling only.
What window sizes fit these window units?
The Window AC with Heat fits double-hung windows 24 to 38.5 inches wide. The U Shaped model fits single- or double-hung windows 22 to 36 inches wide with a 13.75 inch minimum height.
Why do portable ACs list two BTU numbers?
ASHRAE is the older lab rating; SACC adjusts for heat the unit adds back to the room, so it gives a more realistic idea of cooling.
