OK... I was just talking about the coils because a tech said something about the heat is mixing with the cool coils and water going back to the fuhrnance..he cut me a break and didnt charge me... and told me to call the AC guys... (I just had a new AC unit installed last year)... the ac guy came over, I told him what the other tech said... he said i had bad caulking in my bath tub/etc and water is leaking/ resting on the vents... to evaporate into the system. I havent showered in my bathroom in months.. and this is still happening...

Not so much the pilot assy but the ignitor/sensor. They can cause some funny issues.

Thanks.. I've had service techs in for a while... quite a few times...I feel like i just waste money... one more question... the heading of the "chimney" came off a while ago and my dad duck taped it back on... could this cause some kind of problem? just thought of this... is there supposed to be a certain amount of room for vent?

with out really seeing hard to tell ...the pressure switch is suppose to guard against blocked chimney...don't seem like that is causing any trouble.

If the ignitor is glowing red and the gas valve isnt opening then it is probably the gas valve. The only way to know for sure is to be there with a meter when the valve doesnt open to see if its getting a 24V signal. It will also happen when your flue pipe fills with water and your losing pressure from water being sloshed in your inducer assembly. Start by disconnecting the flue pipe to make sure its clear. If it is clear then connec the cap back on correctly and move to the inducer fan housing. Pull off the red hose from the pressure switch and suck on the hose to see if you can get any water from the inducer assembly. If its clear, go buy a cheap voltage meter. When the ignitor is red, have the two leads on the two wire leads on the gas valve. If its showing voltage and the valve isnt opening then it may be the valve. It could also be a frozen gas regulator. We see it all the time.

Chimney cap came off? Check for rust debrie to be in pipe at furnace. may even be inside the inducer.

Moisture in that tube is a sign of low gas pressure, or slight blockage in the vent system.

Could be a cold chimney too...lotsa of those jobs were installed with a vent kit ..although this may not...cant see the pice of the flue.

I don't think any body asked if it was a brick or b-vent. Chances are there was no liner and the condensation collected in the hose.

or if it is a brick chimney is it on an exterior wall or enveloped by the buildings heating envelope. The last time i saw a problem like this on a brick chimney (with a liner) it was just because the chimney clean out was off, chilling the liner.
