My furnace isn't working and I have a service call in. It is a Lennox G32V, installed in 2003.
I had it "maintained" last month. At that time I asked them to be sure the drain was clean, as it failed because of a clogged drain in 2004. He assured me that was part of the maintenance.
This morning it is gurgling, the same as it did when the drain was clogged in 2004. Then it shuts off, just as in 2004.
My belief is that it couldn't have been cleaned properly last month, so I shouldn't be charged for this. I expect they will disagree.
Whatcha think?
(back in 2004 he showed me how to clear it, but it was complicated and I don't remember how...)
