Although most consumers rarely bother to check, your AC’s voltage rating is just as important as the power (watts) rating and amperage. It’s also just as important as the cooling (and heating) capacity of the air conditioner.
Generally, you get to choose between 110-volt and 220-volt models, though you may find others rated 120-volt, 130-volt, 230-volt, and 240-volt.
This guide discusses the benefits of choosing a 110-volt ductless mini-split system. First, though, let’s round up some excellent options when shopping for a 110-volt ductless mini-split air conditioner.
Why is Voltage So Important in Power Systems?
Voltage is such an important concept because it influences appliance power consumption. Electrical energy is carried through conducting material (such as power lines) by electrons.
The transmission line’s voltage rating indicates how much energy each electron carries as it moves through the power line. Meanwhile, the current rating (in watts) measures the number of electrons that flow through the transmission line (or an electrical appliance) per hour.
When you combine the two – voltage and current – you can determine how much power flows through the system. The majority of household appliances are 110V or 220V.
Are Mini-Splits 110V or 220V?
Mini-splits can be 110 volts or 220 volts. The low-capacity models are typically rated 110 volts, while larger capacity models are rated 220 volts.
Is 220 Volts the Same as 240 Volts?
Not really. However, for purposes of electrical connections, the two can be used interchangeably. You can also use 230V connections on 220V or 240V appliances.
So, any of them would do if you’re shopping for a 220V appliance. The same applies to 110V, 115V, and 120V appliances and power lines. Though not equal, they belong to the same category.
The differences are primarily occasioned by the need to accommodate increased traffic loads. Most utilities have increased the minimal voltage to lower electric current and reduce wire sizes to resolve the problem.
Why is it Necessary for Appliances to Match the Voltage Source?
It’s important to match appliances with the voltage source because too little or too much voltage can cause appliance failure or even damage.
Connecting a 110-volt air conditioner to a 220-volt power outlet can cause typically melts the connecting wires and, if there’s no protective mechanism protecting the device, may fry your air conditioner. Meanwhile, if you connect a 220V appliance to a 110V power outlet, it simply won’t work because there’s not enough power to run the appliance.
What to Know About Mini Split Wiring
Wiring a ductless mini-split air conditioner is a simple, straightforward process. However, you need some electrical wiring knowledge.
The first thing you need to know is that you’ll be performing two types of wiring. First, you need to connect the AC power (often labeled L1, L2, and Ground). After that, you must connect the DC Control Voltage (usually labeled 1, 2, and 3).
AC power (110-120V or 220-240V) is supplied from an electrical panel that holds all the circuit breakers for your home. Make sure to match the amperage ratings, i.e., a 15 amp AC goes to a 15 amp breaker. Meanwhile, DC power lines go between the outdoor condenser and indoor air handlers. Typically, you’ll find 3-5 DC lines. Match the wire colors – red to red, black to black, etc.
It’s important to mention that whereas DC control lines are almost always included in the AC package, AC lines are mostly purchased separately.

Simply put, you must match your mini split AC and power supply. If you intend to run your mini-split from a 110-volt power outlet, then buy a 110-volt AC.
If you bring in a 220-volt AC, then you must create a new 220-volt outlet. Otherwise, the AC won’t work. Fortunately, there are dozens of excellent 110-volt ductless mini-splits from which to choose.
