Midea Central Coil 36K BTU 14.7 SEER2 Mini Split Heat Pump — -13°F
This Midea Central Coil system pairs a retrofit evaporator coil with a hyper-heat inverter outdoor unit, converting an existing gas furnace or air handler into a heat pump without replacing the blower or ductwork. The coil sits on top of (or beside) the existing furnace and works with most conventional forced-air systems, and it runs on next-generation R454B refrigerant. It's designed for homeowners who want cold-climate heat pump performance and efficient cooling while keeping the existing furnace as backup or air distribution.
The outdoor unit holds heating operation down to -13°F outdoor ambient, with 27,200 BTU/h maximum heating capacity at 5°F and 36,000 BTU/h rated heating at 47°F. The coil is multi-poise — horizontal right, horizontal left, vertical upflow, or vertical downflow — and includes a secondary drain for flexible routing. The system ships with a programmable wired controller with built-in WiFi and a factory-installed 24V interface for third-party thermostat compatibility. Dual Fuel Mode lets the system switch between the heat pump and the existing furnace automatically, and a factory leak mitigation system monitors the R454B circuit.

Retrofit-Ready Coil
The cased coil installs onto an existing gas furnace or air handler, converting an existing forced-air system into a heat pump without replacing the blower or ductwork.
Heating to -13°F
Operates as a heat pump down to -13°F outdoor ambient, with 27,200 BTU/h max heating output at 5°F — a genuine primary heat source in cold climates.
Dual Fuel Mode
The system switches automatically between the heat pump and the existing furnace based on outdoor temperature and cost — letting you use the cheapest heat source at any moment.
Factory Leak Detection
A factory-installed refrigerant leak detection system monitors the R454B circuit on both the coil and outdoor unit, protecting the compressor and alerting occupants before a leak becomes a safety issue.
Multi-Poise Coil
The coil installs horizontal right, horizontal left, vertical upflow, or vertical downflow — a secondary drain allows flexible routing depending on the existing furnace orientation.
Built-In WiFi Controller
The included wired controller is programmable and has built-in WiFi, so app-based control comes standard without an add-on module. A factory 24V interface also supports most third-party thermostats.
Factory Base Pan Heater
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.
Works With Existing Furnace
Compatible with virtually any conventional furnace (some restrictions apply), and the coil interface is powered from the existing 24V furnace supply — no separate control transformer needed.

Frequently Asked Questions
Will my warranty be valid if I don't use a licensed installer?
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.
Does this system lose heating capacity in cold weather?
Yes, output declines as outdoor temperature drops, like all inverter heat pumps. It operates down to -13°F outdoor ambient, with 27,200 BTU/h max heating at 5°F versus 36,000 BTU/h rated at 47°F — roughly 76% of rated capacity at 5°F. Dual Fuel Mode can call on the existing furnace below the balance point to cover the difference. A manual J load calculation is the right way to confirm sizing at your local design temperature — our team can help before you order.
What is a cased coil, and how is it different from an air handler?
A cased coil is an evaporator coil in a metal cabinet that sits on top of (or beside) an existing furnace or blower, while an air handler is a complete indoor unit with its own blower. A cased coil is the retrofit choice when you have a working furnace and want to add heat-pump heating and cooling without replacing the blower. An air handler makes sense when there's no existing blower, or when you want a fully matched indoor unit.
What's the difference between the CX, BX, and AX coils?
The three coils (D5FULAH36XCX, XBX, and XAX) are all multi-poise cased coils that work with existing furnaces. The main difference is the cabinet dimensions to match your specific furnace plenum. CX is the standard 23.58" x 17.52" x 21" cabinet, AX is slightly narrower in depth at 23.31" x 14.49" x 21", and BX is the widest depth at 24.06" x 21" x 21". Each has its own AHRI certificate and NEEP report, which are linked in the accordions below. Measure your existing furnace plenum opening before ordering — our team can help confirm which coil matches your install.
