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.
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.

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.
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.
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.
The indoor unit runs at just [XX] dBA at low speed, 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.
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.
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.
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.
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.
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.
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.
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.

Professional HVAC installation is required. Self-installation voids the manufacturer's warranty. Everything your contractor needs is in the box, and with free 2-day shipping, your installer won't be waiting on parts.
Electrical Requirements: This unit requires a dedicated 208/230V, 1-phase, 60 Hz circuit with a disconnect box installed near the outdoor unit. A [XX]-amp breaker is recommended. If you don't have an existing 230V line at the installation location, a licensed electrician can set one up. It's a standard job.
Most mini split retailers ship you a box and consider the job done. Filterbuy approaches it differently, and the difference comes from over a decade spent helping homeowners understand and protect their indoor air.
We know that a mini split's performance depends on the maintenance it actually gets. These systems rely on built-in mesh filters that need regular cleaning to maintain airflow, efficiency, and air quality. Most retailers never mention this. We built our entire business around it.

The Filterbuy 12,000 BTU mini split cools and heats rooms up to 250–300 square feet effectively. That covers most standard bedrooms, home offices, guest rooms, single-car garages, and small workshops. If your room has high ceilings, large windows, poor insulation, or significant sun exposure, stepping up to an 18,000 BTU unit is worth considering.
Both deliver the same 12,000 BTU of cooling and heating. The difference is entirely electrical. A 230V mini split draws half the amperage of a 115V unit for identical output, which means a smaller circuit breaker, thinner wire gauge, less panel load, and a cleaner overall installation. The trade-off: 230V requires a dedicated circuit, the same kind that powers your clothes dryer or central AC. A 115V unit runs on a standard household outlet.
For most professional installations, 230V is the industry standard and the preferred choice of HVAC contractors. If your space doesn't have an existing 230V circuit and you'd rather not add one, the 115V model is a solid alternative.
This unit requires a dedicated 208/230V, 1-phase, 60 Hz circuit with a disconnect box near the outdoor unit. Your contractor or electrician will install a [XX]-amp breaker on a dedicated line. It's the same type of circuit that powers central air conditioners, electric dryers, and heat pumps — a standard job for any licensed electrician. If you already have a 230V outlet in your garage, laundry room, or workshop, your electrician can check whether the existing circuit is suitable.
Yes. This system operates as a heat pump, providing both cooling in summer and heating in winter from a single wall-mounted unit. The compressor reverses the refrigerant cycle to pull heat from outdoor air and deliver it inside, even in moderately cold temperatures. One unit handles every season. No separate heating equipment needed.
At the national average electricity rate of $0.15/kWh, a 12,000 BTU mini split with a 17 SEER rating costs roughly $36/month running 8 hours a day. Your actual costs will likely run lower because the variable speed compressor uses less energy when holding a steady temperature and only draws full power during initial cool-down. The 230V configuration may also yield slight efficiency gains from lower line losses at higher voltage.
No. A licensed HVAC contractor is required, and self-installation voids the manufacturer's warranty. The 230V model also requires a licensed electrician to set up the dedicated circuit and disconnect box if one isn't already in place. Everything your contractor needs for the HVAC installation is in the box. With free 2-day shipping, your installer won't be waiting on parts.
Traditional air conditioners use fixed-speed compressors that cycle fully on and fully off to regulate temperature. A variable speed inverter compressor adjusts its speed continuously — high output for rapid cooling, low output to hold a steady temperature. The result is a more consistent room temperature, lower energy consumption, quieter operation, and less compressor wear over time. It's the same technology used in premium systems from Mitsubishi and Daikin.
The indoor unit runs at [XX] dBA at low speed. For context, a whisper measures around 30 dBA, and a typical window air conditioner runs at 50–70 dBA. Mini splits are significantly quieter than window units because the compressor sits outside. At low speed, this system is barely audible.
Many do. If your garage has a dryer, welder, air compressor, EV charger, or heavy-duty power tools, there's a good chance it's already wired with 230V. Look for a larger outlet with horizontal or angled prongs, different from a standard 3-prong outlet. If you're not sure, a licensed electrician can check your panel and outlets quickly. If your garage only has standard 110/120V outlets and you'd rather not add a new circuit, the 115V version of this mini split is worth a look.
Yes, and this is where Filterbuy's expertise makes a real difference. Like all mini splits, this unit has a built-in washable mesh filter that captures dust, pet dander, and airborne particles. For best performance and air quality, clean the filter every 2–4 weeks: remove it from the indoor unit, rinse with water, let it dry completely, and reinstall.
We've spent over a decade helping millions of homeowners stay on top of their air filtration. When you buy a mini split from Filterbuy, that expertise comes with it — maintenance guides, filter care reminders, and the knowledge to keep your indoor air clean and your system running efficiently for years.
This unit comes with a 1-year parts warranty and a 5-year compressor warranty when professionally installed by a licensed HVAC contractor. Professional installation is a warranty requirement — self-installation voids coverage. The 230V model specifically requires installation by both a licensed HVAC technician and a licensed electrician for the dedicated circuit. If you ever need warranty support, our customer team is here to help.
