Great units!
Set name: Dual Zone 9000 BTU+9000 BTU
The units work amazing. Theyre quiet and cool the rooms quickly. I even had an issue in delivery where one arrived without coolent inside and needed the replacement swiftly due to the time frame of my installer. I spoke to a woman named jonah that handled my issue promptly and was very considerate of my needs. ... show more

Great unit for the cost! Solid customer service!
Set name: Dual Zone 9000 BTU+9000 BTU
We purchased this after another minisplit unit had finally run it's course. The install went well, but unfortunately we had an issue with a factory flare joint and lost refrigerant. Customer service was quick to respond to the issue, and got our minisplit up and running within a few weeks of initial contact and it's currently running smoothly and cold! Definitely recommend a Costway minisplit and will be purchasing another one in the future after other renovations are completed. ... show more

Set name: Dual Zone 9000 BTU+9000 BTU
I have 4 mini splits from Senville. Price is cheaper than Senville mini splits but The quality is very similar. They come with everything you need not like other cheaper brands. Installation was simple and straight forward. It fired right up. I would buy another
