Go geothermal, more up front but between your air and heat you will save in the long run by far.
Sorry.
It’s not new construction and I don’t have 30k laying around.
“Go geothermal,”
Gotta drill a couple wells for that, eh? How deep do they have to be? How much moolah? Might work for me, as I already have one unused well. But your electric bill will go up a lot running the pumps in Northern Ohio,,, wouldn’t it?
