$760 Circuit Board or new system ?

Like I said, turning it off for the spring, summer and fall is no big
deal. Is that conservation enough for ya?

As for the winter, the heat coming off the pilot is still radiating
into my house (even it's just adding a little more heat to the
exchanger) - so it's not really lost at all.

It's a similar issue for the (now) hated incandescent light bulb.
During the winter (when there is less natural light) the heat coming
from an incandescent bulb is not really lost - it's actually
supplementing the heat you need from your furnace.

Look,
Your logic is twisted. What about the heat from lamp in summer then?
Bulbs are for illumination not for heat. Turning off pilot in summer?
How about moisture build up inside burner?

Yes, it's true that it's adding heat that I don't want. But also
remember that the days are longer in the summer (at least where I
live) so I have a reduced need to turn on lights in the summer vs the
winter.

The pilot doesn't put out enough heat to prevent that.

If the AC is doing it's job, it keeps the humidity down and should
keep moisture buildup to a minimum.

The proper way to do it is to shunt the air around the heat exchanger
in the summer and shunt it around the evap coil in the winter. That
would improve air flow as well, probably reduce noise too.

Dear "NOT HVAC Guy"
You are clueless as usual. Your 30 yr old furnace may be working but
that's all its doing.
"What does a standing pilot have to do with it?" (you ask)
Nothing other than the fact that you are most likely burning an extra
$20 a month each and every month which amounts to $240 a year you just
pissed away. (and yes, most people dont turn their pilot off in the
summer)
"More expensive to repair?" (you say)
Thats funny. My customers that purchase a furnace from me enjoy a
properly sized furnace that burns at 95% efficient and about half of
them opt for the 2 stage and/or variable speed model. Those customers
also enjoy a 10 yr "no charge" service calls should anything happen to
break down. I only recommend that they purchase a service agreement
for regular maintenance as does the manufacturer although I DONT
require it to honor their warranty.
I'll match 10 yrs of purchase, fuel cost and repairs against your 30
yr old furnace any day.

What else would I want a furnace to do? Is "working" not good enough?

First, I dispute your $20 / month.

Second, the heat put out by the pilot is (mostly) captured within your
house anyways, and during the heating season heat (from all sources)
is desired.

> (and yes, most people dont turn their pilot off in the summer)

Third, I turn off the gas to my furnace during the off-heat months.
