Review: Cool & Happy in Arizona! - I had one of the new fangled double inverter A/C units, I’m in Arizona and that broke in 16 days I think. This is not as efficient supposedly as that one, but this one has lasted far longer than that. I’m hoping for 5 or 6 years at least. It has only been around 5 weeks. So I’m in Az in the extreme heat summer, my house is cool. The A/C cycles on and off. My electric bill is not bad at all. I am very happy so far!
Review: Air conditioner - Bought 2 years ago, still going . Use in summer and winter

### ⭐⭐⭐⭐⭐ Air conditioner
*by C***N on June 11, 2026*

Bought 2 years ago, still going . Use in summer and winter

### ⭐ Error code less than a month later
*by J***O on August 20, 2025*

Don’t waste your money. This unit is too expensive to already be having issues. It also didn’t cool a 746 sqft area to the point it ran ALL DAY. We accepted that because we were grateful to have a cooler area. But now an E3 error code has popped up and nothing we’ve done has fixed it. It’s 91 degrees outside, currently 86 indoors and keystone is not available for product help. This is beyond ridiculous and unacceptable!!!!
