Midea, Carrier and two Midea lineups
Midea Group was established in 1968, is headquartered in southern China, and calls itself the world's leading manufacturer of home appliances. Its US research hub, the Midea America Research Center, is in Louisville, Kentucky. Midea also has a long history with Carrier. In 2017, when Carrier and Midea America launched a North American residential ductless joint venture called Carrier Midea North America, Carrier took the majority stake and described Midea as a long-time supplier of its residential ductless systems. Our Carrier page covers that side of the family.
Midea-brand heat pumps now reach Minnesota homes through two channels. The Midea Home Comfort line's US website is operated by Carrier, and its copyright line reads CMNA, LLC. Midea also runs its own North American HVAC business, selling EVOX ducted heat pumps and single-zone and multi-zone ductless systems through distributors. Both carry the Midea name, but they're separate product families with their own model numbers and literature.
How do you read a Midea model number?
On the Midea Home Comfort line, the model number tells you what you're looking at. Outdoor units start with 37M: the 37MAHA single-zone heat pump, the 37MGHA and 37MGRA multi-zone heat pumps, the 37MUHA crossover heat pump. Indoor units start with 45M: the 45MAHA and 45MPHA high walls, the 45MBCA cassette, the 45MCFA and 45MBFA consoles, the 45MBDA ducted unit, and air handlers such as the 45MUAA. EVOX and Midea's own ductless lines use different numbering, so we take the full model and serial number off both units before ordering anything.
The repair itself follows the usual ductless pattern. We read the fault code, then check the filter, coil and drain, the communication wiring between the indoor and outdoor units, and the flare joints if the system lost capacity. Midea lists R-454B on current models such as the 37MAHA, 37MGHA and EVOX G3, while older installs are often R-410A, so the charge and any replacement parts have to match the label. Our ductless service page lists what a visit includes.
Midea heat pumps in a Minnesota winter
Midea publishes cold-weather numbers by line. It lists the 37MAHA single-zone heat pump at 100% heating capacity at 5°F, with a built-in basepan heater. The EVOX G3 system is listed at 100% heating output at -13°F. On its single-zone ductless page, Midea credits its EVI (enhanced vapor injection) technology with heating at -22°F. Those are solid numbers, and the Twin Cities still get -20°F nights, when any heat pump makes less heat than it does at 5°F. We size to the home's heat loss and keep auxiliary or backup heat in the plan.
Two Midea features suit Minnesota properties. The basepan heaters on units such as the 37MAHA and the 37MGHA multi-zone help defrost water drain instead of freezing into the bottom of the outdoor unit. And the 37MAHA's 46°F heating setback mode can hold an empty cabin or garage at 46°F instead of full living temperature. If your house is off the gas lines, our post on switching from propane to a heat pump walks through the fuel side.
What is the Midea EVOX G3?
The EVOX G3 is Midea's all-electric ducted system: an inverter heat pump from 1.5 to 5 tons with a matching air handler that Midea says can directly replace an existing gas furnace. It accepts 24V or RS-485 control, can talk to Midea's communicating thermostat without communication wiring, and takes an optional 3-stage auxiliary heat kit for the coldest hours. The 45M air handlers in the Midea Home Comfort line can also replace a traditional ducted gas furnace.
In Minnesota that's a big decision. Going all-electric means the heat pump and the auxiliary heat carry every January night, so we check the heat loss, the electrical service and the ductwork before we quote it. Many homes do better keeping the furnace as backup in a dual fuel setup. Our comparison of electric furnaces and heat pumps and our heat pump service page cover both paths. Heat pump systems we install run $7,500–$14,500.
How long is the Midea Home Comfort warranty?
For the Midea Home Comfort line, Midea's product pages list a 10-year parts limited warranty for the original owner in an owner-occupied home when the equipment is registered on time, dropping to 5 years if it isn't registered within 90 days. Keep the model numbers, serial numbers and install date together.
Call 612-429-3465, 7am to 9pm any day. A service call is a $79 trip charge, waived when you approve the repair, and you get a written flat-rate price before work starts. Repairs carry our 1-year parts-and-labor warranty.
Midea questions
Is my Midea mini-split made by Carrier?
Closer to the other way around. When Carrier and Midea America launched their North American ductless joint venture in 2017, Carrier described Midea as a long-time supplier of its residential ductless systems. Today the Midea Home Comfort line, with 37M outdoor and 45M indoor model numbers, has a US website operated by Carrier with a CMNA, LLC copyright, and Midea Group owns the Midea trademark.
How cold can a Midea heat pump heat?
Midea lists the 37MAHA single-zone heat pump at 100% heating capacity at 5°F and the EVOX G3 system at 100% heating output at -13°F. On its single-zone ductless page it credits EVI technology with heating at -22°F. Twin Cities nights reach -20°F, so we still size to the home's heat loss and keep auxiliary or backup heat in the plan.
Can a Midea air handler replace my gas furnace?
Midea says so. It sells the EVOX G3 air handler as a possible direct replacement for an existing gas furnace, with an optional 3-stage auxiliary heat kit, and its 45M air handlers can also replace a ducted gas furnace. In Minnesota we check the heat loss, the electrical service and the ductwork first, and many homes are better off keeping gas as backup.
Do I need to register a Midea system?
For the longer coverage, yes. Midea Home Comfort product pages list a 10-year parts limited warranty for the original owner in an owner-occupied home with timely registration, and 5 years if the equipment isn't registered within 90 days. Check your warranty certificate for the details, and keep the model numbers, serial numbers and install date in one place.
What does Midea service cost?
A $79 trip charge, the same flat price in every town we serve, waived when you approve the repair. You get a written flat-rate price before any work, and completed repairs carry our 1-year parts-and-labor warranty. Maintenance visits run $129–$349, depending on the system.
