I get an unsolicited call around a month ago and it's a woman who says
they are with a program that might install a heater in my house
(Berkeley, CA). She didn't say that exactly, but that's where the
conversation went because that's what I need. The heater in my almost
2000 square foot two story 101 year old house was a floor heater
that's been disconnected and in the crawl space under the house,
rusting since I moved in here in 1983. I bought the house (was
renting with others before) in 2000.
.. . .

If I have just one heater it will cost me around $7500, with 2 it
will be $13,290 after 2 rebates from my utility company, PGE
(evidently about $150 each), a "voucher amount" of $4000, federal tax
credit of $400.

ANY "offer" with a 3-day deadline is likely to be a scam. $7500 for a
single Trane 95% furnace is WAY TOO MUCH even BEFORE any "vouchers,"
rebates, or credits!

If you really need a new furnace, call several reputable companies and
get estimates. Trane, York, Lennox, and a few other major furnace
brands are equivalent in most respects.
