I just got an estimate from one local dealer who said that he would
need to replace it with a conventional air heat pump with electric
heat. The unit is bigger (a 4 ton based on his calcs, and my terrible
ductwork/access problem), SEER 19, would require me to get an
elctrician to install a sub-panel for the outside unit, etc.
His quote : $10, 641.
Baton Rouge dealer estimate to replace the existing GHP with a SEER 14
WaterFurnace Versatec (economy model) having almost the exact same
physical dimensions - $5500-$6000.
Looks like I'll get the "replacement" done whenever I can get the guy
here from Baton Rouge ...
