Dick, living in the low desert I know heat and much of the time, certainly not all, my current unit will keep us comfortable. That being said it’s that’s in temp only, The noise level is horrid. Which that video shows in their own high end units. The difference in the new units being 15 dB less they point out is showing that the current ac unit they have offered is 5 times louder on the high setting compared to this other companies offering. It also put out cooler temps at a lower power use as you’ll see in the other video. It’s impressive and I’ll bet more expensive than what we can currently buy here. I’m ok with that, I’m willing to pay more to not have to put up with the roar. I hate the roar of the ac unit on high. That and the rattle every time it kicks the compressor in and out. New models I’m sure are better but what this company found is so much better in the noise level of what they or anyone else had to offer previously here in the states.
