The best 115V mini splits of 2026

Why 115V matters

• No panel project. A 115V unit can run on a standard-voltage circuit, avoiding the cost and hassle of adding a 230V circuit or upgrading the panel.
• Great for apartments, additions, and older homes where 230V capacity is tight - see best mini splits for an apartment and for a room addition.
• The honest caveat: 115V still almost always means a dedicated circuit sized to the unit's published requirements - not sharing the bedroom outlet. Confirm the actual circuit with the electrical lookup and a licensed electrician.

The capacity limit

115V caps how much power the unit can draw, so these systems generally run 9,000-12,000 BTU - enough for a bedroom, office, small living room, or addition. If your room needs more (the sizing calculator will tell you), you're into 230V territory.

Best overall 115V: MRCOOL DIY 12k

The MRCOOL DIY 5th Generation 12k 115V is the standout: it combines 115V simplicity with the DIY precharged install path, so you skip both the 230V circuit and the professional refrigerant work. Strong certified efficiency, warranty valid on self-install. For most 115V buyers, it's the one to start with.

Best 115V for a small room: MRCOOL DIY 9k

For a bedroom, office, or small addition, the MRCOOL DIY 5th Generation 9k 115V is the smallest, easiest 115V option - the least demanding on your electrical while still DIY. Confirm the room's load first so you don't undersize.

Best 115V value (professional install): Pioneer Quantum

If you're hiring the install, the Pioneer Quantum Ultra 12k 115V is a widely available 115V value unit with solid certified efficiency for the price - a strong pick when you want low cost and standard voltage without the DIY route.

Best budget 115V: Cooper & Hunter MIA

The Cooper & Hunter MIA Series 12k 115V is a lower-cost 115V single-zone for buyers who want the cheapest standard-voltage equipment and are handling the install professionally.

How we picked

Every unit here is verified against manufacturer documentation and AHRI certificates, and we publish certified capacity and efficiency rather than marketing figures. We don't take payment for placement. Confirm the exact circuit requirement on each model page before you buy.

Before you buy a 115V mini split

• Size the room first. 115V caps capacity near 12k; if the load is higher, you need 230V (sizing calculator).
• Plan the dedicated circuit, and expect it to be bigger than 15 amps. This is the part 115V marketing quietly skips. Of the 115V systems we track that publish a maximum breaker size, only 9 of 48 can run on a 15-amp circuit. 26 require 20 amps and 12 require 25 amps, with minimum circuit ampacity running from 10 up to 19.5 amps. A 25-amp circuit at 115V is not a standard household branch circuit - it needs heavier wire than the 14-gauge most 15-amp receptacle circuits are run in. Budget an electrician unless you already have a suitable dedicated circuit.
• Consider DIY. A 115V DIY unit is the easiest full install path for a homeowner - see best DIY mini splits.

FAQ

Can a mini split run on 110V/115V? Yes - many single-room units (up to about 12,000 BTU) run on standard 115V. Larger systems need 230V.

Does a 115V mini split plug into a regular outlet? Usually not - it almost always needs its own dedicated circuit, even though the voltage is standard. And the circuit is usually larger than the 15 amps most household receptacle circuits are wired for: across the 115V systems we track that publish one, 39 of 48 call for more than a 15-amp breaker. Check the model's published requirements before assuming an existing outlet will do.

What size mini split can run on 115V? Generally up to about 12,000 BTU. Beyond that the current draw requires a 230V circuit.

What's the best 115V mini split? The MRCOOL DIY 12k - it pairs standard voltage with the DIY install path. For a professional install, the Pioneer Quantum is a strong value.
