The Midea 36K BTU central air handler heat pump delivers 15.9 SEER2 efficiency on R454B refrigerant, with heating operation down to -13 F outdoor ambient and 24,200 BTU/h max heating at 5 F. The multi-position AHU installs upflow, downflow, or horizontal, and features a factory-installed leak detection system, an easy-to-use 24V thermostat interface, automatic airflow adjustment for clogged filters, and sensor redundancy for emergency operation. Backed by a 7-year compressor / 5-year parts warranty.
This Midea Central AHU system pairs a multi-position indoor air handler with a cold-climate inverter outdoor unit, delivering whole-home comfort through existing or new ductwork. The air handler can be installed vertically upflow, vertically downflow, horizontally left, or horizontally right — a direct fit for replacement central systems and new construction where a mechanical closet is already in place. It runs on next-generation R454B refrigerant and holds heating operation down to -13°F outdoor ambient.
The system holds a maximum heating capacity of 24,200 BTU/h at 5°F and 38,000 BTU/h rated heating at 47°F, with rated cooling of 36,000 BTU/h at 95°F. The air handler includes a factory-installed refrigerant leak detection system, aluminum hydrophilic pre-coated fins, and a 24V interface for third-party thermostat compatibility. Automatic airflow adjustment compensates for filter loading, and self-diagnostics with fault-code display make troubleshooting straightforward. Optional electric heat packages are available separately for backup heating or code compliance in cold jurisdictions.

Operates as a heat pump down to -13°F outdoor ambient, with 24,200 BTU/h max heating output at 5°F — a genuine primary heat source in cold climates without backup.
Installs upflow, downflow, horizontal left, or horizontal right without a different cabinet — a drop-in fit for existing duct layouts, furnace closets, and new construction.
The microprocessor detects increased motor torque from a loaded filter or coil and adjusts fan speed to hold CFM steady — maintaining performance between filter changes.
A factory-installed refrigerant leak detection system monitors the R454B circuit and alerts before a leak becomes a safety issue — protecting the compressor and occupants.
The air handler self-diagnoses faults and displays the corresponding code on the electric function board behind the lid — faster service calls and fewer misdiagnosed parts.
The included 24V interface works with most conventional thermostats, so you're not locked into a proprietary controller if you prefer a smart thermostat ecosystem.
If one temperature sensor fails, the system continues operating with an error code and allows emergency use. Only multiple sensor failures shut the system down.
Both a base pan heater and a crankcase heater are installed at the factory on the outdoor unit, preventing ice accumulation and protecting the compressor in freezing weather.

No. This is a traditional line-set system — brazing, evacuation and charging the refrigerant circuit must be performed by an EPA 608-certified technician. Midea's warranty also depends on professional installation and online registration via the link in the warranty section above. Our team can answer sizing and line-set questions before you order — just call or email.
Yes, output declines as outdoor temperature drops, like all inverter heat pumps. It operates down to -13°F outdoor ambient, with 24,200 BTU/h max heating at 5°F versus 38,000 BTU/h rated at 47°F — roughly 64% of rated capacity at 5°F. A manual J load calculation is the right way to confirm sizing at your local design temperature — our team can help before you order.
A multi-position air handler can be installed vertically upflow (in a closet), vertically downflow, or horizontally (in an attic or crawlspace), without buying a different cabinet for each orientation. If your existing ductwork enters from the top, bottom, or side, the installer can configure the cabinet to match rather than re-routing ducts. This is the standard configuration for replacement central systems where the mechanical space is already fixed.
No. Electric heat packages are sold separately. They're not required for normal operation — the outdoor unit is designed as a primary heat source down to -13°F — but they're often added for backup heating, faster recovery after setbacks, or to meet local code requirements in cold jurisdictions.

Switching to this Midea heat pump was the best decision Iβve made for my home all year! It keeps the whole house perfectly cool in the summer and cozy in the winter without ever making a sound. My favorite part is that my monthly power bills have noticeably dropped, and it hooked right up to the smart thermostat I already loved using.
