Midea 12K Hi-Heat Pump System

Midea 12K Hi-Heat Pump — rated to -22°F, R454B refrigerant, and ENERGY STAR certified.

β˜… Product Features

Hi-Heat Performance to -22°F

Rated heating down to -22°F outdoor ambient — maintains 95% of rated heat output at 5°F and is a true primary heat source in extreme winter climates without backup heat.

Intelligent EYE Sensor

Detects occupancy and adjusts airflow direction to avoid blowing directly on people — smarter comfort with less energy waste in unoccupied areas.

Leak Mitigation Sensor

Monitors refrigerant levels and alerts you to potential leaks before performance drops — protects the compressor and extends system life.

Active Clean (i-Clean)

Automatically dries the indoor coil after cooling to inhibit mold and bacteria growth — keeps air fresh and extends coil life.

Humidity Control

Built-in humidity sensor monitors indoor moisture and adjusts operation to maintain optimal comfort and inhibit mold growth.

Follow Me & Breeze Away

Follow Me uses the remote's sensor for localized comfort. Breeze Away redirects airflow away from occupants for draft-free cooling.

Factory Base Pan & Crankcase Heaters

Both heaters come factory-installed — they prevent ice accumulation and protect the compressor in freezing weather.

1%–100% Fan Speed & Dual Swing

Precise 1%–100% fan speed control. Horizontal and vertical auto-swing louvers circulate air into every corner of the room.

❓ Frequently Asked Questions
How cold can this system operate?
Yes — this Hi-Heat Pump system is rated for heating down to -22°F, making it a true primary heat source in the most severe winter climates without needing backup heat. It maintains 95% of rated heat output at 5°F where most standard heat pumps lose significant output below 25°F.
What is the Intelligent EYE Sensor?
The EYE Sensor detects occupancy in the room and automatically adjusts airflow direction to avoid blowing directly on people — improving comfort while reducing energy waste in unoccupied areas.
What smart controls are included?
The package includes built-in Wi-Fi for control via the Midea app, plus a standard IR remote and a built-in Leak Mitigation Sensor for diagnostics.
Will my warranty be valid if I don't use a licensed installer?
No. To maintain the manufacturer warranty, this system must be installed by a licensed HVAC technician. DIY installation voids the warranty. Registration is also REQUIRED at mideaductlesswarranty.com.

It’s a high-performance workhorse tucked inside a sleek, quiet shell.

Patrick Skipper · May 2026

It uses R-454B, so you aren’t buying into "old" tech that’ll be obsolete in a few years. You’ll honestly forget it’s running. Even on higher fan speeds, it’s more of a low hum than a mechanical roar. After putting the Midea Hyper Heat to the test, the word that comes to mind is effortless.
