We needed to replace the Living Room air conditioner and were so happy with HOW QUIET this air conditioner is. You can actually hear the TV fine while it is running. We were so happy about how quiet it is that we replaced the Main Bedroom air conditiioner as well even though the old loud one was still running fine. The low whoosh of this air conditioner is like the perfect white noise for sleeping. I will not know until the July and August electric bill about the 25% less energy used but I expect that to be true too. The only con is I set up the wifi but it keeps losing the connection so I gave up and just use the timer.
