A residential mini split is sized for a bedroom or a living room. Put one in a busy restaurant dining room or an open office and it'll run nonstop just to keep up. Mitsubishi P-Series mini-split systems are made for spaces like that. This is the brand's light commercial line, with bigger capacities and indoor units built for larger rooms, higher ceilings and heavier daily use. Below are the P-Series models we carry, including Hyper-Heat versions for colder regions.

What Are P-Series Mini-Split Systems?

P-Series mini-split systems pair an outdoor unit with an indoor unit, much like a home setup, but they're designed with bigger spaces in mind. Think offices, retail stores, restaurants, churches, workshops and large open-plan homes.

Most people just call it Mitsubishi P-Series. It's a common choice as a commercial mini split system in buildings where running new ductwork isn't practical, or where one large room needs its own dedicated unit. Each indoor unit has its own controls, so that space can be set independently from the rest of the building.

P-Series vs M-Series

The M-Series is Mitsubishi's residential line, the wall mounts and floor units you see in most homes. The P-Series steps up in capacity and is built for the longer, heavier workloads of commercial spaces. If you're cooling a single bedroom, our single zone heat pump systems cover that. For a 40-seat restaurant or a showroom floor, a commercial mini split from the P-Series is the better match.

Why Choose a Mitsubishi Commercial Mini Split

• Capacity for big rooms. Larger outputs handle open floor plans and high ceilings that would wear out a residential unit.
• Inverter-driven compressor. Output follows the load, which helps where occupancy changes through the day, like a restaurant at lunch versus mid-afternoon.
• Heating and cooling in one. A Mitsubishi P-Series heat pump handles both seasons. Cooling only models are also available.
• Indoor units made for commercial ceilings. Cassettes, ceiling suspended units and ducted options keep equipment off the walls.
• Hyper-Heat options. Cold-climate versions keep heating through freezing weather.

P-Series Indoor Unit Styles

• Four-way ceiling cassette: Sits flush in a drop ceiling and spreads air in four directions. A common pick for offices and retail floors.
• Ceiling suspended: Hangs below the ceiling. Good for spaces without a drop ceiling, like restaurants with exposed structure or workshops.
• Wall mount: Suits smaller commercial rooms or large living spaces where a wall unit makes sense.
• Ducted: Hidden above the ceiling, moving air through short duct runs. Only the grilles show.
• Multi-position air handler: Fits closets, mechanical rooms and attics, and connects to ductwork.
• Cased coils: Work alongside a furnace for a dual-fuel setup.

Working in a cold region? Hyper-Heat P-Series models pair with these same indoor styles. A shop in Minnesota can run the same kind of commercial mini split system as an office in Georgia, with a cold-climate outdoor unit doing the extra work in winter.

How to Choose a Commercial Mini Split

• Size for the real load. People, kitchen equipment, lighting, windows and ceiling height all add heat. A busy restaurant needs far more capacity than an office of the same size.
• Match the ceiling. A drop ceiling suits a cassette. An exposed or hard ceiling suits a ceiling suspended unit. Ducted works if you want it hidden.
• Check your climate. Long freezing winters point toward Hyper-Heat.

Covering several separate rooms from one outdoor unit? Mitsubishi multi-zone heat pump systems may fit better.

No. The line is built for commercial use, but larger homes with big open rooms use P-Series mini-split systems too.

Q2. P-Series vs M-Series: what's the difference?

The M-Series is the residential line. A Mitsubishi P-Series heat pump offers higher capacity for larger and commercial spaces.

Q3. Can a Mitsubishi commercial mini split heat and cool?

Heat pump models do both. Each product listing shows whether a model is heat pump or cooling only.
