05 · 1 kWh, how much heat?

What 1 kWh gives, size by size.

Pick a model and a temperature: here is how many kWh of heat come out per kWh of electricity, from the NEEP list COPs, and what a kWh of heat costs at Rate D.

Model
Outside

COPs published by the NEEP list (ashp.neep.org, data by AHRI number, Oct. 8, 2026): rated at 8, -8 and -15 °C; at the coldest point, at maximum output, as reported by the manufacturer. Electric baseboard: about 100% efficient (NRCan, “Heating with Electricity”). Hydro-Québec Rate D in force April 1, 2026: 7.065¢/kWh up to 40 kWh per day, 11.142¢/kWh beyond, plus the access charge. A lab COP is not a bill: real use depends on the house and how it is used.

07 · The indoor unit

The EVOX G3 comes in three blocks. Does it fit in your home?

Pick the size and enter the free space in your closet or basement: we tell you whether the EVOX G3 indoor unit fits.

Six positions

According to Midea, the EVOX G3 indoor unit installs six ways: upflow, downflow, horizontal left or right, and low-boy. We match it to your ducts.

A furnace’s footprint

Midea compares its width to a gas furnace: the old furnace comes out and the unit goes in the same spot.

Optional backup heat

Midea electric kit up to 25 kW, sized at the visit for the house.

Quiet indoors

Midea states an indoor unit from 31.5 dB(A).

Midea Atom X central heat pump
Atom X: a different indoor unit.

The Atom X pairs with the MIH unit, a multi-position air handler from Midea’s VRF range. Its dimensions are on each product page.

The indoor units are also in the Midea electric furnace collection

08 · What Midea puts inside

What Midea built into its central units.

The features Midea states for the EVOX G3 and the Atom X.

EVOX G3
EVOX G3Enhanced vapor injection (EVI)

In deep cold, the compressor gets medium-temperature vapor to raise the refrigerant flow and heat harder, according to Midea.

EVOX G3100% down to -25 °C

Midea states 100% of the heat down to -25 °C and operation down to -30 °C. The certified figures for each size are in the table above.

EVOX G3Cooling in a heat wave

The ICE circuit cools the control board: Midea states cooling operation up to 50 °C, and 100% capacity up to 43 °C.

EVOX G3No on-off cycling

The variable-speed compressor adjusts its speed instead of stopping and restarting: steadier temperature and less noise, according to Midea.

EVOX G3Screwless assembly

The indoor unit modules lock with latches: they come apart to go down a narrow staircase and go back together on site.

ENERGY STARCold climate, six sizes

All six EVOX G3 combinations in our catalogue are ENERGY STAR cold climate certified, up to 19.0 SEER2 at 1.5 tons.

Atom X
Atom XVariable-speed mini VRF

The Atom X comes from Midea Building Technologies’ VRF range: a variable-speed outdoor unit, from 1.5 to 5 tons.

Atom XFrom -30 °C to 52 °C

Midea states heating down to -30 °C (-22 °F) and cooling up to 52 °C (125 °F).

Atom XAutomatic refrigerant charging

The system does its own R-454B refrigerant charge at start-up, according to Midea.

Atom XLong line sets

According to Midea: up to 90 m for the longest run, 300 m of piping in total and 50 m of height difference between the outdoor and indoor units.

Atom XR-454B refrigerant

According to Midea, the Atom X’s R-454B has a global warming potential of 466, versus 2,088 for the R-410A of earlier generations.

ENERGY STARCold climate, six sizes

All six Atom X combinations in our catalogue are ENERGY STAR cold climate certified, up to 18.0 SEER2 at 2.5 tons.

16 · True or false?

Five common beliefs about central units.

Answer, then read why.

Question 1 / 5Score 0
  1. “A Midea central unit can connect to existing ducts.”

    True. Yes, it is designed for that: for the EVOX G3, Midea states constant airflow up to 1.2 in. of static pressure. We check the condition and size of your ducts at the visit.

    Midea EVOX G³ leaflet, p. 7.

  2. “The EVOX G3 must be wired for one voltage only.”

    False. It detects 115 V or 208-230 V on its own, according to Midea.

    Midea EVOX G³ leaflet, p. 5.

  3. “An M-coil spreads air better than an A-coil.”

    True. 2% difference between the two sides versus 30%, according to Midea.

    Midea EVOX G³ leaflet, p. 4.

  4. “All our Midea central units keep a COP above 1 at -30 °C.”

    False. Only eleven out of twelve: the 1.5-ton EVOX G3 drops to 0.99 at -30 °C, per the NEEP list.

    NEEP list, data by AHRI number, Oct. 8, 2026.

  5. “A regular 24 V thermostat works with the EVOX G3.”

    True. Midea lists a conventional or communicating thermostat (24 V or RS-485).

17 · Frequently asked questions

What people ask us about Midea central units.

Both are 1.5 to 5-ton central units that run down to -30 °C according to Midea. The EVOX G3 is Midea Comfort’s modular central unit, with 100% of the heat stated down to -25 °C; at -30 °C, the NEEP list gives 11,800 BTU/h to 37,300 BTU/h depending on size. The Atom X comes from Midea’s VRF range: 8,270 BTU/h to 18,500 BTU/h at -30 °C. Most of our published Midea central installs are EVOX G3.
