What parts are good to keep on hand for a gas furnace? I have 2 Trane/
American Standard gas furnaces in the basement, about 7 years old. I
just replaced the pressure switches, and the ignitor on one of them
(went bad at 6 PM on New Year's Eve...). So today I am ordering a
spare ignitor, as it will fit either furnace and I DON'T want to pay
another $500 emergency call-out for such a simple part.
So what else should I keep on hand? I.e., what items have a fair-
chance of total failure, can be installed by a DIY-er, and aren't
extremely expensive? In my experience, pressure switches are pretty
inexpensive, but they can be cleaned / blown out, so you have time to
order a new one after they start going bad.

If you reply, I would greatly appreciate it if you could also respond
directly to my email address. Thanks in advance,

Ignitor, pressure switches, blower motor, motor capacitor, thermostat.

Control board if you can justify the cost.

Bear in mind that just the basics help.

Also note that an alternative heat source is really the key...and one
that will kick in automatically with you not being there.
