6 Best 115V Mini-Split Air Conditioners of 2026
We compared six 115V single-zone mini split heat pumps on room coverage, cold-weather heating, efficiency, smart control, installation and warranty.
By Daniel Brooks
Updated October 19, 2026
A 115V mini split runs on the same voltage as a standard household circuit, which is why it is often the easiest way to add ductless heating and cooling to an older home, a condo or an addition where the electrical panel has little room to spare. You still need a dedicated circuit, but you avoid the double-pole breaker and heavier wiring a 230 volt system requires. Our list of the best 115V mini-split air conditioners compares six single-zone heat pumps on room coverage, cold-weather heating, efficiency, smart control, installation and warranty. To browse every model we cover, visit our Single-Zone Mini-Split Air Conditioners page.
Almost every 115V mini split tops out at 12,000 BTU, so all six systems here are 1 ton units. The choice comes down to how cold you need it to heat, whether you want Wi-Fi in the box, and whether you plan to install it yourself.

#2 Pioneer Diamante Pro 12000 BTU 115V Mini Split Heat Pump: Best for Cold Climates

It lists 20.0 SEER2 and 9.5 HSPF2, and heating capacity matches cooling at 12,000 BTU/H. Pioneer recommends it for 350 to 500 sq ft.
Motorized up-down and left-right louvers sweep air across the room, and the remote’s I FEEL function reads the temperature where you sit.

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. That removes the vacuum pump, flaring tools and HVAC visit that a conventional system needs.
It is digital assistant-ready with Google Assistant and Amazon Alexa support, and you can also use the app, remote or push button. A sleep function adjusts the temperature overnight to save energy, and the washable filters rinse clean with water. The box includes the system and line set. It has a 4.1 average from 75 ratings.

Other Models Worth Considering
Della Vario 12000 BTU 115V Mini Split AC with Heat Pump. A 20.5 SEER2 heat pump for up to 550 Sq.Ft with Della+ app and Alexa control built in, heating down to -4F, 4D airflow and an I Feel remote. Della lists 28 dBa and a 25A maximum fuse, and offers lifetime parts coverage when you register within 100 days. It has a 4.4 average from 1,470 ratings shared across the Vario series.
Cooper & Hunter MIA 12,000 BTU 115V Mini Split AC. A 21.2 SEER2 system with a smart kit for app control in the box, a 16ft pre-flared and insulated copper line set, 16ft communication wires and a 16ft drainage extension. It heats down to 5F, lists 26 dB and carries 7 years on the compressor and 5 on parts once the professional installation is registered. It has a 4.3 average from 577 ratings.
Mountman 12000 BTU Mini Split AC/Heating System. The budget pick, rated for up to 600 Sq.Ft in the title, with 19 SEER2, 4 fan speeds, a 26dB sleep mode, ECO and turbo modes, self-clean and automatic defrost on 110/120V. It is remote-only and lists a 1-year protection. It has a 4.5 average from 368 ratings shared across the Mountman series.
What to Expect from 115V Mini-Split Air Conditioners
A 115V mini split is almost always a 1 ton system rated for one room. It needs its own dedicated circuit and an outdoor disconnect, but the wiring is simpler than for a 230 volt system, and many panels can take it without an upgrade. Efficiency at this voltage is excellent, with several models listing more than 20 SEER2. Heating range varies more, from about 5F on standard models to -4F on cold-climate designs.
For more options, see our guides to 12,000 BTU mini-split air conditioners and single-zone mini-split air conditioners. The product cards show the current price for each system.
How to Choose a 115V Mini-Split Air Conditioner
Size the System to the Room
ENERGY STAR publishes this general guide for sizing a room air conditioner by 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 |
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.
Plan the Circuit
A 115V system still draws a significant current. Senville lists 12.7 amps for the LETO, and Della specifies a 25A maximum fuse for the Vario. Have an electrician add a dedicated circuit and an outdoor disconnect sized to the manufacturer’s requirements.
Match Heating to Your Climate
For cold snaps, the Pioneer Diamante Pro and Della Vario both list heating down to -4F. In mild climates, a heat pump rated to 5F, like the Senville LETO or Cooper & Hunter MIA, is enough.
Decide Who Installs It
Five of these systems need a technician to connect and vacuum the line set. The MRCOOL Easy Pro is designed for DIY installation without special tools.
How We Evaluate 115V Mini-Split Air Conditioners
We rank mini splits on manufacturer specifications, listing details and aggregated buyer ratings. For this list, we kept only single-zone wall-mounted heat pumps that run on a 110 to 120 volt supply, and excluded 230 volt systems, multi-zone bundles and listings with too little data. We weighed heating range, efficiency, track record and room coverage first, then compared smart features, installation needs, noise and warranty.
Frequently Asked Questions
Can a 115V mini split plug into a regular outlet?
