I'm in Maryland. My old heat pump used the backup electric heat in
Jan & Feb, especially at night.
I asked about geothermal and this installer told me that the
installation would be over $20,000 here. I don't have a well, a large
yard, or pond nearby. Maybe I'll ask the next guy that comes by on
Monday to see what he says.
I would be willing to pay more to for a geothermal, especially if it
will pay for itself in lower costs over time, but the $23k price tag
says to me I should wait a bit longer.
