Filterbuy 12,000 BTU Ductless Mini Split AC & Heat Pump | 230V | 17 SEER2
The 12,000 BTU 230V Mini Split: Same Output, Half the Amps
A 12,000 BTU 230V ductless mini split cools and heats a room up to 300 square feet, and it draws half the amperage a 115V unit needs for the same output. That lower current means a smaller circuit breaker, thinner wire, and less load on your electrical panel — the same voltage your contractor already uses for central AC and dryers. It is a variable-speed inverter heat pump, so one wall-mounted unit handles both summer cooling and winter heating, with app control and free 2-day shipping.
115V vs 230V — both 12,000 BTU:
- 115V — runs on a standard household outlet; full amp draw.
- 230V — needs a dedicated circuit; half the amps, smaller breaker, thinner wire.

About This Mini Split
Ask any HVAC contractor which voltage they'd rather work with, and the answer is almost always 230. It's what powers every central AC, heat pump, and major appliance they install. This mini split is built to that same standard.
At 208/230 volts, a 1-ton mini split draws half the amperage of a 115V unit for identical cooling and heating output. That difference shows up in practical ways: a smaller circuit breaker, thinner wire gauge, and less strain on your electrical panel.
If you're adding climate control to a garage, workshop, home addition, or back house, there's a good chance 230V power is already in the space. A dryer outlet, a welder, an EV charger — your contractor can tie into an existing circuit or run a new dedicated line quickly and affordably. It's the same voltage they work with on every central AC job.
Inside, a variable-speed DC inverter compressor adjusts output to match your room's actual demand. It runs at full power for rapid cooling and backs off to a whisper once you've hit your target temperature, which means lower energy use, more consistent comfort, and less compressor wear over time. Built-in WiFi and app control put your system at your fingertips, and the wall-mounted indoor unit keeps your floor space completely clear.
Every unit ships free in 2 days with everything your contractor needs already in the box. Your installer arrives ready to work. Professional-grade quality from the air quality experts at Filterbuy.
Why Choose the 230V Model?
The HVAC industry runs on 230V for a reason. At that voltage, this mini split draws half the amperage of a 115V unit for the same 12,000 BTU output — same watts, higher voltage, lower current. The physics are simple, and the practical difference shows up immediately:
Smaller Circuit Breaker and Thinner Wire Gauge, which can lower your installation material costs
Less Load on Your Electrical Panel, important if your home is already running close to capacity
The Same Voltage Your Contractor Works With Every Day. 230V powers central AC systems, heat pumps, and large appliances. No special setup, no surprises.
Already have 230V power in the space? Many garages, workshops, and laundry rooms are wired with 230V for dryers, welders, EV chargers, or heavy-duty power tools. If that's your situation, your contractor can get this unit installed with minimal electrical work.

Built for Professional Performance
Variable Speed Efficiency
The DC inverter compressor reads your room's demand and adjusts its speed accordingly, using less energy to hold a steady temperature and ramping up only when you need rapid cooling or heating. Fixed-speed systems cycle fully on and fully off to regulate temperature, which wastes energy and accelerates compressor wear. The variable speed approach delivers lower electricity bills, more consistent comfort, and a longer system life.
Lower Amp Draw at 230V
At 230 volts, this unit draws half the amperage of an equivalent 115V system. In practical terms, a smaller circuit breaker, thinner wire gauge, and less strain on your home's electrical panel. For contractors, it's a cleaner installation. For homeowners, it means lower material costs and a setup that matches the same professional standard as your central AC.
Smart App Control
Control your comfort from anywhere with built-in WiFi and the dedicated mobile app. Adjust temperature, set schedules, switch modes, and keep tabs on your system from your phone. That's especially useful for garages and workshops you don't visit every day — your space is at the right temperature the moment you walk in.
Whisper-Quiet Operation
The indoor unit runs as low as 28 dB in Mute Mode, significantly quieter than window air conditioners, which typically run at 50–70 dBA. Because the compressor lives outside, the noisiest part of the system never enters your room. Sleep mode drops output even further for bedrooms and guest rooms where silence matters.
Year-Round Comfort
This unit is a heat pump, not just an air conditioner. It reverses the refrigerant cycle to provide heating in winter and cooling in summer from a single wall-mounted unit. One system handles every season, with no separate space heaters or supplemental equipment to manage.
Self-Cleaning Technology
An automated self-cleaning cycle dries the indoor unit's evaporator coil after each use, which stops mold and bacteria from building up inside the system. Mold in your mini split degrades air quality and shortens system life. Most units at this price point don't include this feature. Every Filterbuy unit does.
Perfect for Rooms Up to 550 Sq Ft
Garages & Workshops
Most garages already have 230V power for a dryer, welder, air compressor, or EV charger. Tying a mini split into a space that's already wired for 230V is a straightforward job for any licensed contractor. Year-round climate control turns a garage from a space you avoid in July and January into a shop where you can actually work.
Home Additions & Back Houses
New construction almost always runs 230V circuits as standard. If you're building an addition, ADU, casita, or guest house, your electrician is likely pulling 230V wire anyway. This mini split fits right into that plan — one unit for heating and cooling, no ductwork to route through newly framed walls.
Converted Spaces
Finished basements, attic conversions, enclosed porches — these are spaces that were never connected to your home's central HVAC. A ductless mini split gives them independent climate control without tearing into ceilings or walls to run ductwork. The 230V model keeps the electrical installation clean and efficient.
Bedrooms & Home Offices
When a contractor handles the installation, 230V is the professional default. Sleep mode and whisper-quiet operation make this unit a natural fit for bedrooms and home offices where comfort and silence carry equal weight. Zone control means your space holds exactly the temperature you set, independent of the rest of the house.
Small Commercial Spaces
Server rooms, retail shops, and small offices — commercial buildings run on 230V almost universally. This mini split delivers efficient, app-controllable climate control to small commercial environments where centralized HVAC is either overkill or simply not available.
