HVAC in hotter climates should be mandated to have ground-coupled heat exchanger systems. It's easier to exchange heat with 59F soil, 30 feet down in the ground than it is to exchange heat with 110F air.
After a while the ground starts absorbing all that heat. The ground retains heat much better than the air. So... at first it will work better but after a while the ground would get hot and stay hot.
@@WeSRT4 The ground does retain heat better than air, but it also radiates that heat back into the environment through the ground itself. After a while, this heat dissipation through the ground balances out, so the ground doesn’t keep getting hotter indefinitely.
@@WeSRT4 It costs at least $50,000. That's why. But with the right system, their heat pump system would be 500% efficient, year round, no matter how hot or cold it is.
I have a question that I put on other channels but I didn’t get an answer. Therefore I was hoping that you’ll answer me. Why is it that the fans are designed to spin in opposite directions. Also, why is the only one side of the unit runs most of the time? I’ve seen lots of these units in my have. And I notice that one side will run regularly and the other side will not run. Why is that?
