A friend calls me just now. She has gas heat, forced air, and the
furnace is broken. The repairman comes but not until 4. He says she
doesn't have enough gas pressure, and he did something that made it a
little higher, but he said she needs a part and he said the furnace
wasn't safe so he turned it off. He also told her the furnace was so
old it wasn't worth replacing the part, but she says the furance is
only about 15 years old. IIUC he's supposed to call her tomorrow
when he learns more about the part. I don't know the furnace make
or model.

I've never heard of low gas pressure caused by a furnace or anything
in the house???

The heat has been broken for a few days, I gather, and it's 60 degrees
in the house and tonight is supposed to be down to 17 (maybe it was
yesterday it was supposed to be colder than that) and she's worried
the pipe to her kitchen sink will freeze. The sink is against a
window so does that mean the pipes are in the outer wall or might they
come in through the middle of the area under the sink??? It's a
split level house, but I don't know what part of the basement is under
the kitchen. I told her to leave both hot and cold running a
trickle, and to make sure they don't shut themselves off. I've had
that happen.

She's supposed to call me back with the make and model of a
radiator-style room heater that is so complicated she can't figure out
how to turn it on. I'm hoping the instructions are online. A timer,
two modes, etc. she's not good at stuff like this she says.

I told her to boil water to raise the humidity. Her stove works fine,
so why is the gas pressure low at the furnace?

Should I volunteer to go over there? I'm waiting for a phone call
about tomorrow at 7:30am but that should be soon.
