I have searched and read as much as I can about this. I understand that it takes away outside storage. But, does it work any better that two air conditioners mounted on the roof? Does it really cool quicker? Less noisy?
If so, why isn't everybody else offering it?
Just curious.
Cold air falls, hot air rises. That tells me something about efficiency.
At home, my air handler is in the attic and the vents are in the ceiling.
If one of your roof ac's quits, you still have another or two, until you get it fixed. Not sure about basement air.
Also need all the storage, we can get.
Actually basement air would be a deal breaker for me.
Not sure what you're saying. Our basement air is ducted and blows out through ceiling vents. That fact that the unit is in a basement compartment vs the roof makes little to no difference. In fact not having it sitting on the roof, baking in the sun should help it cool better. Our home AC unit sits outside and is ducted through the furnace ducts, it will freeze you out. Yours is in the attic, the hottest place they could find to put it. I know it's common in some areas but doesn't make sense to me.
The basement unit has 2 compressors so if one quits you still have another. True a total system failure would take them both out.
Your home A/C unit sits outside but that isn't where the air is coming from. That outside unit is just cooling the Freon which is circulating to your heater which is where the fan is except it's blowing cold air chilled by the Freon instead of hot air heated by the burner.
