Love the quiet operation, the consistency in house temperature and the lower energy bills.
Best Air conditioner Ever
September 7, 2026
By far, this has been one of the best investments in my home. It is all I have ever dreamed of. It is quiet, uses less power, all the features given on the thermostat display, plus the app. It is amazing. I would only improve the app flexibility to match the Google nests options, as well as it could be a little quieter.
Well worth the money.

The best. It barely makes a sound and will freeze me out of the house. When our other AC goes out, we will add another.
Quality in the Condenser and Blower
August 15, 2026
Very quite and smooth running but the thermostat humidity reading is way off so it runs constantly.
