A single lady friend called me for advice and exposed the one area of home engineering I know nearly nothing about. I've never had a heat pump Here's the Q. 2 of the elements of her heating system are, a heat pump and a bunch of crap up in the attic that it's attached to. It's all maybe 20-25 years old. The heat pump has gone bad, like anything that sits outside for that long. The problem is, nobody wants to replace just the pump and claim that the whole system needs to be upgraded...estimates in the 8-$9k range. Of course, she assumes people are trying to hose her because she's a woman and clearly has some dough. BTW...the attic is accessible by a 2'x3' hatch in the ceiling of a closet.
