MRCOOL Easy Pro 12,000 BTU Review: DIY 115V Mini Split
MRCOOL's Easy Pro is a do-it-yourself 1 ton heat pump: no special tools or vacuum pump, a 115V supply, Alexa and Google Assistant control and a line set in the box.

The MRCOOL Easy Pro 12,000 BTU is built for one job that most mini splits cannot do: let a handy homeowner install it without an HVAC technician. MRCOOL says no special tools, equipment or expertise are needed to set up this 115V wall-mounted heat pump, which delivers 12,000 BTU of heating and cooling for rooms up to 550 square feet. It is the DIY choice in our single-zone mini-split air conditioners category, with a 4.1 out of 5 average from 75 ratings.
Our Verdict
If hiring an installer is the obstacle between you and a mini split, the Easy Pro is the answer. You avoid the vacuum pump, flaring tools and gauges that a conventional system needs, and you can run it on a 115V circuit, which most homes can add without a panel upgrade. It also works with Amazon Alexa and Google Assistant, and the washable filters rinse clean with water.
The trade-off is cost. The Easy Pro is priced well above conventional systems of the same capacity, so the savings come from skipping professional labor, not from the equipment itself. The listed sound level of 43 dB is also higher than many rivals, and the compressor warranty shown in the specifications is 2 years.

What Makes It DIY
A conventional mini split arrives with the refrigerant sealed in the outdoor unit. The installer flares the copper lines, connects them, pulls a deep vacuum to remove air and moisture, and then releases the refrigerant. That step needs a vacuum pump, a micron gauge and experience, and doing it wrong can ruin the compressor.
MRCOOL designs the Easy Pro so that a homeowner can skip that process. The listing states that no special tools, equipment or expertise are needed to set it up. You still need to mount the indoor and outdoor units securely, drill a hole through the wall for the lines and drain, and provide a proper electrical connection, but the refrigerant side is designed to be simple.
Cooling Capacity and Room Size
MRCOOL rates the Easy Pro 12,000 BTU for rooms up to 550 square feet, including bedrooms, living rooms and small offices. That matches the top of the 12,000 BTU band in the ENERGY STAR chart below, so the rating is realistic.
ENERGY STAR publishes this general guide for matching cooling capacity to floor area:
| Room Size (sq ft) | Cooling Capacity (BTU/hr) |
|---|---|
| 100 to 150 | 5,000 |
| 150 to 250 | 6,000 |
| 250 to 300 | 7,000 |
| 300 to 350 | 8,000 |
| 350 to 400 | 9,000 |
| 400 to 450 | 10,000 |
| 450 to 550 | 12,000 |
| 550 to 700 | 14,000 |
| 700 to 1,000 | 18,000 |
| 1,000 to 1,200 | 21,000 |
| 1,200 to 1,400 | 23,000 |
| 1,400 to 1,500 | 24,000 |
| 1,500 to 2,000 | 30,000 |
| 2,000 to 2,500 | 34,000 |
Adjust for your room: reduce capacity by 10 percent for a heavily shaded room, increase it by 10 percent for a very sunny room, add 600 BTU for each regular occupant beyond two, and add 4,000 BTU if the unit cools a kitchen. Source: ENERGY STAR.
Heating Performance
The inverter heat pump delivers the same 12,000 BTU of heating, so the Easy Pro handles both seasons from one unit. MRCOOL does not publish a minimum outdoor temperature in this listing, so in a cold climate, plan on a backup heat source for the coldest weeks.
Efficiency
MRCOOL describes the Easy Pro as designed for power efficiency, and the listing shows a rated draw of 586 watts. A sleep function adjusts the temperature overnight to save energy. As with any inverter system, the compressor slows down once the room is at temperature, which is where most of the savings come from.
Smart Control
The Easy Pro is digital assistant-ready, with support for Google Assistant and Amazon Alexa. You can also use the app, the remote or the push button on the unit, which covers every way you are likely to want to change the temperature.
Noise
The specifications list 43 dB. MRCOOL describes the operation as whisper-quiet, and in practice an inverter at low speed is far quieter than a window unit, but the listed figure is higher than some conventional mini splits in this guide. Light sleepers may want to compare it with quieter models.
Electrical Requirements
The Easy Pro runs on 115 volts. A mini split should still be on a dedicated circuit with an outdoor disconnect, and local codes may require an electrician for that part of the job. Many DIY installers handle the mechanical work themselves and hire an electrician for the circuit, which still costs far less than a full HVAC install.
Is DIY Worth the Premium?
The Easy Pro’s price only makes sense when you compare installed cost, not box price. A conventional 12,000 BTU system plus professional labor, permits and a new circuit can end up costing as much as, or more than, the Easy Pro installed by a homeowner. The math favors the Easy Pro most in rural areas where HVAC installers are scarce or book weeks out, in rental units where a landlord wants to handle the job in-house, and in cabins or shops where scheduling a technician is a hassle.
If you already have a trusted installer who quotes a fair price, a conventional system will usually give you more efficiency and a longer warranty for the money. If you are comfortable with tools, drilling through an exterior wall and following a detailed manual, the Easy Pro removes the biggest barrier to getting a mini split.
Planning a DIY Install
Pick an indoor spot high on an outside wall, with clear space in front of the unit and a path for the line set and drain to slope downward through the wall. Choose an outdoor location within reach of the included line set that is level, drains well and is protected from falling snow and ice. Read the manual end to end before you start, and have a helper for lifting the outdoor unit.
