Perfect for My Cabin! Efficient, Quiet & Smart!
I installed this 12,000 BTU mini split in my cozy wooden cabin and I’m beyond impressed. I hired a pro and the installation is about 4 hours. The unit looks sleek and modern, blending perfectly with the wood-paneled walls.

So far is good
Before purchasing, I asked customer service many questions, such as how to choose the right size and delivery time. Customer service responded promptly, and the delivery was very fast (only took 2 days from ordering to receiving the goods!). So far, everything has gone smoothly, and I have scheduled a professional to come and install it.

Q:
Why are the 14 AWG and 18 AWG wire harnesses sent with this model when the MOP / max fuse ( fusible Max. ) is 25 Amp both wire harnesses are under rated and are a possible fire hazard or meltdown. What can you do for me about this ?
A:
Thank you for your concern. The 14 AWG and 18 AWG wire harnesses are used for internal control circuits, not for carrying the full 25A load. The MOP rating applies to the main power supply, which requires properly sized field wiring per installation codes. All included wiring meets safety requirements for its intended use. If preferred, you may use your own compliant wiring for installation.

Q:
What does the dry setting do? I'm looking to only control humidity in my garage. Will the dry setting do the job?
A:
Under dehumidification mode, it cannot change the humidity, it is fixed. It doesn't refer to a precise humidity level like with a dedicated dehumidifier. The air conditioner's dehumidification function works differently and isn't as accurate. The actual humidity level largely depends on the room size. For example, in a smaller space like a 10–15 sqm bedroom, it might reduce humidity to around 40%. In a larger area, such as a 30 sqm living room, the humidity would likely stay around 50%.

The power supply for the unit is directly connected to the circuit breaker. It does not plug into a standard outlet. For installation guidance, it's recommended to refer to the installation video provided by Costway for detailed steps on how to connect the power supply properly.

Still Confused?
Q:
Had a technical question about the r32 refrigerant charge. If I use the supplied 13 ft line sets are these units precharged with enough r32 refrigerant to be used with the supplied line sets. Or is there only enough charge for the compressor where I would have to buy additional line sets with r32 refrigerant.
A:
This unit comes pre-charged with R32 refrigerant, and it is designed to be used with the supplied 13 ft line sets. Therefore, you do not need to buy additional refrigerant or line sets for standard installation with the provided line length. The pre-charged amount is sufficient for the compressor and the supplied line sets.
