Weil-Mclain CG-4 SPN Boiler - it's not working
Any one have any idea how old this unit might be?? Moved into our house and found out the boiler had not been used since May. Now we're told that the pilot light being out for 4 months has caused condensation and rusting within the unit and the readings?? are too high so the unit has to be replaced. Apparently this is something that can't be fixed with new parts. Is this true or are we being taken for a ride? The hot water tank is fine and that pilot is on.

Sounds like a scam to me. The pilot being off should not cause corrosion. Actually, the pilot being on during the summer might more likely cause condensation.
"Readings are too high"? "Can't be fixed with new parts"? What parts? What readings?
What, if anything, seems to be wrong with your system? Have you tried to run it?
Find somebody who is recommended by people you trust. And, check their references personally.

You are more than likely being taken for a ride, as long as the boiler is not leaking, it can be cleaned, as for readings, they are talking CO readings, I'm guessing and there are no parts to replace, just needs to be cleaned, not a fun process for the person doing it, but, it can be done, buy yourself a LOOONG bottle brush and tear your boiler apart, pull the burners out and run the brush down through all the slots until you get all the dirt and carbon out, put it all back together and it should be fine.. Ok so unless your pretty mechanically inclined i wouldn't really do it, but thats the idea. I've done it many times and about 98% of the time it works the other times it is caused by the burners being wore out, but thats rare. now it should be adjusted by someone that actually knows what they're doing and that has the right equipment. and it should be fine.

We feel it's a sham too. The furnace came on without a problem, it was a little noisy, but it worked. I think it's at least 18-20 years old and hasn't had a cleaning in quite a while. Thanks for the info!

Give that thing a GOOD thorough cleaning along with some TLC (and thorough cleaning at least every other year) and it will last for another twenty years. Be forewarned though that you will likely need to remove the sheetmetal casing and some interior baffles or insulation to thoroughly clean the boiler and it WILL be a dirty job.
