One of my rental houses started looking like that. But just in one corner. When I washed the coils there is a hole a little larger than a softball of fins missing and about 4 tubes exposed. I did not cover the hole, but thought about it. I did build a little 1x4 board fence around it to keep the dogs away. This was two years ago. No leaks, still works, normal pressures. One day it will fail and I will throw a 13 SEER 410a unit in. The unit you repaired was 500% worse than the one I dealt with. I would have been afraid to try and sweat new pipe in. The surrounding tubes must be thin! +1 Good job! CT
lol..wow
Dang, one of these days I'm gunna hafta be teached how to read. Sorry guys I missed the part about it being for a friend.
I would have remove the bottom run from the system and saved the copper!!LOL!!!
Yeah, a couple hundred bucks in gas or a new 4 ton dry charge? It did develop a leak in the indoor coil after a week of running. Quick check at the supply house netted me a 4 ton r22 expansion valve cased coil for $75. Tossed that on. Probably got $400 in a 4 ton system that will work for a while. Just doing a favor for a good friend.

The customer is a friend he was doing a favor for. There was no charge for the labor.

You sure it was a dog?

Only for a friend...and a good one at that. Nice work. Speaking of piss, specifically the amonia therein; I am beginning to see the relationship between the abundance of animal urine in the carpets and in the air (at least I certainly hope it's animal urine...can't be sure with some of the places we go into) and the premature deterioration of indoor coils, ignitors etc. I'm told I would be surprised if I were to piss in a cup and throw a penny in and let it sit for a few days. I'll take their word for it - my wife is barely tolerant of my work bench in the shop...

I've used the expandable builder foam to fill a couple like that but on hot days the pressures werent normal, head was way up.
Its amazing what piss can do
Originally Posted by machery I would have taken some sheet metal and covered that whole section up, I bet all of the air is drawn thru that area and not anywhere else.

A real close friend bought the house, been empty 3 years, been up there every night after work fixing tons of problems. Wanting to get through this summer. Then its zone time and redo everything. POS install. 4 ton unit. Just want it to last a couple months tops. I did block the hole off. Pressures seemed to be pretty normal actually. Lacking in the airflow department inside, but that's due to the morons that think a 5 ton drive will pull thru a 16x25 filter.
As already stated, some sheet metal over the opening would do wonders.
Nice repair anyway.
