4/5
So far, so good
August 07, 2025Overall, I’m happy with my AC. My house is cooling nicely. I have yet to receive my first power bill to see any change in efficiency. My only complaint is that it is louder than I expected it to be and wakes me up at night. And, not the Ac, but the thermostat, is a bit challenging to figure out and set. It’s way too complicated for my liking. It is also about 3° lower than my old thermostat and my other room thermometer, so I’m having to adjust to that as well.
5/5
