Thread: Any of you guys seen one of these furnaces before?

This thing was cool, even though it didnt work. Just want to see approx what age it might be. The HVAC guy there (in business for 25 years) had never seen this before.

Yep, Lennox has been around for quite a while. I'm guessing that one is 1950-60 era from the styling.

JL, do you think it could date back to the origional age of the house, 1938?

See them all the time in LA. Compton, Watts, Bell those areas are loaded with them.

OLD stuff there

Ooooo, thats why... the houses where I work are typically newer. Wow, you must be doing a lot of crawling.

I don't know, could be but I'm not THAT old.

Seen lots of those, used to take them out all the time. Monsters but they keep working.

Looks very similar to these. They were from 1962. The were Lennox furnaces.

Good call.

Definitely not original with a 1938 home.

We all have to start somewhere. New houses are a good place to get your feet wet. The old houses are where the greatest challenges lie and where the real learning begins.

Looks like the HVAC guy hasn't gotten around much in the last 25 years.

I would say these were built in the early 1960. They were built just before the Lennox "Dura Curve"

Yes, but Marc's has a round top with a handle for the front cover - mid 50's, and could be older.

Get my feet wet? Ive been doing this since early 90's. I 've done houses from 1800 to 2010. I have no idea why with thousands of houses that I have inspected, i have never seen this specific furnace before. Like I said, I mainly work in an area where houses are newer, 1960+. If I do 30 a month, 2-3 of those may be earlier than 60's. So as you can see, it would take me longer to get around to house that might have a unit like this with rations like this.

When I was in Colorado I did some that dates to the 1800s in Cripple Creek , and Leadville CO. The difference here in the amount of work involved, for the same money is a joke. The only thing nice in Colorado was the pretty much guaranteed Radon test. Give me the slab on grade, no basements, no furnaces and you guys can have all the crawlspaces.

PK, you hit it on the money. Why do a 6 hour inspection, 6 hour report for $400 or $500. Not worth it. I'll take mid 80's all day long. No crawling, no dirt, and there hasnt been 100 years for people to DYI it to death.

Hi (ALL) &

Yessirree - I know someone with a 'twin' /clone to that one = installed in '62...

Gotta go soon, but he insists it "still runs, so why would I replace it! ?"

Some people just cannot see the 'big picture' as to wasted $$ due to the very low-efficiency & relatively HIGH risk of failure...


CHEERS !
