Does a mini split run on 110 or 220?
A mini split system can run on both 110 and 220 volt circuits, depending on the model. 110-volt models are typically used to cover smaller areas such as bedrooms or offices and require dedicated circuits, while 220-volt models are usually used to cover larger areas requiring heavier power draws.
In general, mini splits use either a 10 or 15 amp circuit, depending on the size and type of mini split. Because of their higher power consumption, 220-volt mini splits may require a dedicated breaker.
Many models can also be wired to multiple circuits. Before installation, it is always important to consult your local electrician or the manufacturer’s guidelines to determine the correct type of circuit and voltage necessary for your particular mini split system.
How many square feet will a 18000 BTU mini split heat?
A 18000 BTU mini split heating system will cover approximately 450 to 575 square feet of space depending on local climate, wall and ceiling insulation, as well as window area. For example, if you have a lot of glass and your walls and ceiling do not have great insulation, then you might need a larger capacity heating system and the square footage would need to be lower than 450 square feet.
To accurately determine the necessary BTU capacity and the square footage a unit can cover, it is recommended to consult a heating specialist or HVAC professional.
Does MRCOOL come with electrical wiring?
No, the MRCOOL line of air conditioners and heat pumps does not come with electrical wiring. Depending on the type of unit, installation can vary, but for most models, you will need to have a professional install the necessary electrical wiring required to safely operate the unit.
Your local MRCOOL dealership or HVAC contractor should be able to help you with this. In some cases, the installation may even require you to have an electrician install a dedicated outlet for the unit, as well as any other wiring as needed.
If you are a do-it-yourself type of person, you can also consult your local home improvement store for all the necessary electrical supplies and tools needed to complete the installation.
How do you power MRCOOL?
MRCOOL air conditioners are typically powered by electricity. The requirements for this vary from model to model and must be consulted in the product’s manual. In general, all MRCOOL air conditioners require a dedicated circuit and should be connected to a single-phase power supply of the correct voltage, hertz (Hz) and ampere (A).

How are a mini split systems typically wired?
Mini split systems typically come with a “communication wiring” bundle or “road” wire. This is a bundle of cable that runs between the outdoor condenser unit and the air handlers/indoor units. It typically contains one or more power cables that run from the outdoor unit to the indoor unit; this powers the fan and compressor motors.
There may also be a control cable that powers the temperature sensing devices and communication lines between the outdoor and indoor units. In addition, there may be two or more circuit protection wires that protect each component of the mini-split system in the event of a short circuit or power overload.
The indoor unit will then also be connected to the thermostat/remote control device with a two-conductor wire that carries power and commands. Lastly, the outdoor unit is usually connected to a 220-volt breaker, and the indoor units may also be connected to their own 120-volt breakers.
This allows for the individual controls of each indoor unit or zone.
Is MRCOOL easy to install?
Yes, MRCOOL is easy to install. MRCOOL systems are specifically engineered to be easy to install with minimal tools and require no extra wiring. All but the MRCOOL mini-splits, which come pre-charged with refrigerant and only need to be connected to a simple, three-wire electrical circuit, are split systems, which come pre-assembled in two pieces—an indoor air handler and an outdoor compressor/condenser.
The split system is a separate entity from the main HVAC system, connected to a coil, where you only need to make the refrigerant lines, condensate drains, and electrical connections. To help you with installation and maintenance, MRCOOL also provides detailed instructions, customer support, and online videos featuring experienced service technicians.
To top it off, MRCOOL also offers extended warranty protection for up to 10 years.
Can mini split be connected to a regular outlet?
No, a mini split cannot be connected to a regular outlet. Mini split systems require a dedicated and correctly sized line that must be installed by a certified electrician to ensure the line meets the amperage, voltage and circuit breaker load required for the unit.
It is important to always follow the manufacturer’s instructions when connecting any unit. If the instructions indicate that a dedicated line must be installed, attempting to connect the unit to a regular outlet could cause serious damage to the home, such as electrical fires, and could void your warranty.
How hard is to hook up a mini split?
Hooking up a mini split can be relatively simple for a novice do-it-yourselfer, but there are a few factors to consider before starting. The most important aspect of the installation process is to make sure you follow all of the manufacturer’s instructions.
Start by selecting a location for the indoor and outdoor units, making sure there is a direct line of sight between them and both units have adequate clearance. If they’re not resting level on a flat surface, use the mounting brackets included with the kit.
Once those steps are completed, you will have to connect the condensate line and refrigerant lines between the two units. If you’re not comfortable with this part of the installation, it’s a good idea to have a professional do it.
You also need to double check that power requirements are met by the breaker system and a floating switch is installed. Finally, you’ll need to use a vacuum pump and test the system for any leaks, adding refrigerant as needed.
Installation of a mini split can be more complicated than a traditional HVAC system, so make sure to read the instructions for the mini split thoroughly before beginning.
