We had siding put on our home a month ago and rock at th bottom. A week ago we turned in ac for the first time to realize it's not cooling. We called Ahs warranty co to check it out and it has no freon! The ac man said if we can't locate it or it's behind the walls, that we would have to cut from inside or outside to find/replace line or just put a new line around our house to fix.
We and the siding co spent a lot of time and effort to hide all electrical and plumbing before the new siding was put on so that we didn't see anything, but a beautiful house from the outside!
Is there any way o test the line so we can find the leak without massive destruction, mess and heartache or to have to run a very long pipe around and up our house to fix it?
We can't see putting a new line on the outside that needs new insulation every year, looks like junk and may not cool well because its on the hit side of the house.
The ac man only checked for leaks on the exposed copper lines by the outside unit.
Dye test, nitrogen test, compressed air and a Stethoscope??????
If this is not the right forum...could someone tell me where to go?
Thanks in advance
you could possibly use ultrasound and dry nitrogen to find an approximate area of the leak by its whistle. at that point, if no punching of the line is vislble, you could use leak detecting soapy water. the commercial version is gellish, so the bubbles last longer.
with an LED inspection camera, all you have to do is drill half inch holes along the line to get visibility... oops, dang, drilled through the line
notice that the "repairman" sent out by the "home warranty service" came to a conclusion and went away. that is an indication of how hard they work for you.This message has been edited. Last edited by: swschrad,
sig: if this is a new economy, how come they still want my old-fashioned money?
So they checked the outside exposed lines by the outside unit. Where do those lines go from there, like maybe into the attic????
Maybe the siders put a hole in the copper line with a nail or screw or something. Maybe if that copper line goes vertical, then removal of the inside drywall would be the best way to search for the problem. Or does the copper lines go horizontal through studs?
Questions exist due to different ways of building things in different parts of the country -- or just in the way your house was built. Have you contacted the siders and asked their opinion.??This message has been edited. Last edited by: Re-mdlr,
The short story is that if the leak is within the walls or behind the siding it will be very difficult to find. The AC guys are faces with the possibility of spending lots of man-hours with nothing to show for it or recommending the 100% solution of running a new line.
It's also not likely a coincidence that the siding job and the AC problems are so close together. considering this, a little detective work could help out. The copper AC line is going to take the most direct path from the outside unit to the inside one. Find where the line enters the house from the outside and where it enters the attic space. See if you can find any screws or nails that could have damaged the line in these areas.
Then call the Heat 7 Air guys back. You cannot work on or recharge the freon line anyway - it's a pretty regulated thing. So you need to work together with them. All the pros know that a leak like this can be hard to find so most would prefer to just run a new line. If you can at least give them some likely locations for the leak, you can convince them to check those spots.
I'm thinking the lines enter the wall in the lower section, then go vertical up the wall and enter the attic through the double top plate. So cutting out the drywall where it is would be pretty easy. But first I would climb into the attic and make sure where that line comes up.
Then removing the drywall and insulation and looking for a nail or screw wouldn't be that bad. But I'm a hands on kind of guy anyway. But if the siders put a hole in the line, I'd like to prove it, and let them pay for the repairs.
And I wonder what "siding" was installed. And if it has hidden nails?? Or can you just spot them, and how long are they??
