  • Highly recommended!
Voltage: 115.0 Volts Cooling power: 12000.0 British Thermal Units
I can highly recommend this very well put together package. I purchased this unit with hesitation because it was the cheapest 12,000 BTU mini split on Amazon at the time. And no, I am not receiving any thing for my review. It is not a true DIY because you have to vacuum the indoor air handler and may have to flare the lines if you need them to be sure or longer. There are no instructions, but if you need more information on the unit, you can find it at auxair.com But that aside I can’t imagine you could ever beat the price for the quality of this unit. The electrical lines UL listed. The exterior bracket is stainless steel (same bracket is $40 on Amazon). The included fasteners are all of high-quality. It even arrived two days before the due date. ... show more

  • good pick for a price
Voltage: 230.0 Volts Cooling power: 12000.0 British Thermal Units
Decent air conditioner, and fairly easy to install, even though both the instructions and the video are rather limited - watch other videos about split installs so you know what you're doing. Overall: - hanger for outside unit is included but rather low quality steel and is not suitable for framing. Get a decent one instead. - the wall hole on a template is larger than enough, a 2" hole is sufficient to pass everything; - the refrigerant is pre-charged; - the pipes are pre-flared so you don't need to flare them unless you cut them; - vacuuming is required; Kwik e-vac works and is probably a cheapest and easiest option; - both the outdoor and indoor units are very quiet. Little to no vibration on wooden framing. ... show more

  • Good system
Voltage: 115.0 Volts Cooling power: 12000.0 British Thermal Units
The systems(I purchased 2) are working well. I chose these because my HVAC is too large to be run by my generator when the power goes out. The systems will run easily on my generator. The instructions are descent but they assume you have AC installation knowledge. One unit had some impact dents where it it was hit in transit. The dents did not effect the function. ... show more

  • I am no a/c pro but I installed it, you can too.
Voltage: 115.0 Volts Cooling power: 12000.0 British Thermal Units
Like the description says, it needs vacuumed. It probably wouldn't have hurt to do it the official way and call a pro. But I did not. I ordered a vacuum pump and guage kit from the Amazonian and now its frosty in my garage machine shop. I will update if it craps out but 2 hours in and the shop is 10 degrees cooler. Good deal. ... show more
