HVAC question

I looked at a 115 year old home yesterday which had many upgrades. A heat supply vent was run through a closet to get to the second floor along with some exposed romex. I can understand the problem with the romex but what about the supply pipe? Does it have to be enclosed in a chase?

Also, all the doors on the second level were out of square and would not function very well along with the hallway floor which had settled about a 1/2 on one side. Is this typical of a house of this age?

I’m not sure what your ‘code’ down in the Excited States calls for in terms of the vent or the romex, although I suspect that the romex should be covered to prevent damage and probably set back from the heat duct.

I see a lot of houses in my area that are 150+ years old. MOST of them have settlement issues as you have described. The question is; " Is this a recent development or has it been going on for the last 100 years?". All houses subside eventually and in a house this age it is usually pretty easy to discover what is causing it and what if anything can be done to arrest the process.

Some purchasers look on these subsidences as a ‘feature’ of the house ( I guess they like the fact that if they drop something it automatically roles to the middle of the house!!) Others view it a s a warning that the entire structure is about to collapse and possibly drag the neighbours house in with it.

The truth lies somewhere in between.

The cause, in my experience is usually a poorly supported main beam in the basement which has deflected over the years. In fairness to the builders of the 1800 of this area, they usually used a massive log ( probably cut on site) squared it by hand and placed it on supports as a main beam. I often find that someone has removed some or all of the supports over the years and the result is a deflected beam. Look for dry rot or excessive humidity too as both can cause a big beam to sag.

Did you get into the crawl space? That is usually where you will find your answer.

don’t they still make homes like that up there? or do they use some kind of new anti melting paste for the igloos? BTW i am just kidding you

WAYNE - WELL OH YA ??!? ( is that a great come-back or what?) We live in peat houses not igloos!
