Yeah I was actually purposely poking holes in burner chambers in furnaces at an apartment complex I worked at because the cheap fucks wanted us to keep wire brushing the rust out of them and fixing roasted wires from flame-ups. Made those bitches replace the furnace
But yeah safety aside ( ) a new one will pay for itself in a couple years, and I can save a fuckton of money because I'll install it!
Oh I know... I had to deal with ones from the 1960's that literally would blow their own doors off because of cracked or rusted out heat exchangers.
Luckily it's in a dry basement and at least the house has been kept clean and maintained... but yeah it's gotta go. It'll make a nice garage furnace
Also the house had a wood stove and fireplace that was used most of the time it was built so I think the furnace wasn't used too hard.
I have one, but my gf's dad unhooked it and stored it under the basement stairs and we dunno why. I plan to hook it back up after I give the chimney a once-over.
The thermocouple is fine, the pilot is fine... but the furnace is from 1972.
It's an 80,000 BTU input. I can replace it with a brand new 50,000 BTU 80% efficiency unit and cut about a third off of my energy costs.
