Yeah, i didn't choose mine either
Did you move out of denham?
Eta: it's possible/likely they have fixed the major issue with the evaporator

Sure did, I don't live very far from CarRamrod.
.4 miles away per google maps.

Coil leak ...chinese drywall?

Unfortunately any number of things can come in to play on somwthing like this. I don't sell Goodman equipment, but I won't bash it. Most equipment is basically the same. It's really all in who installs it. Maybe there's a chance you can toe your serial number to the original installer and see how their work is.
Either way you should probably find someone you trust that knows some about AC service to take a look before you get screwed by a random contractor.

R22 is all over eBay when I just looked

Possible, but you'd have other problems.
Basically all the coils made out of aluminum fins and copper tubing spontaneously leak. That's why all the manufacturers moved to all-aluminum or tin-plating to keep copper from touching dissimilar metals. Goodman moved a bit later than most, but the coils they've been supplying the last couple of years have been all-aluminum and should be as good as any. The OP said he has a 5 y/o Goodman coil, and as I mentioned earlier, this implies he has the old, bad Al-Cu coil. The good news is that it can now be replaced without a strong chance of the new coil failing in the same way within a year. Of course, he needs a leak test done to try and see what exactly is leaking.

Willing to bet "inside" coil like everyone else. I sell to multifamily props and 90% prefer Goodman over anything else. Normally they take a beating and keep humming along. Depending on size, slant coil will cost 300-600 and around the same in labor to replace. The crazy thing is you could damn near buy the whole air handler for the cost of the coil, but the cost of install would be more. My bro owns a hvac co and I can get discounted parts ...I'd replace the coil. Without the homeboy hook up I'd keep nursing her along. Side note: If you aren't familiar with r22 and how to use gauges I'd highly advise to stay away from doing yourself.

Im dealing with the same issue. I have Rheem units in my house. They are only about 7 years old but 2 of the three systems have new compressors and now the third has an evaporator coil leak. Our system also has the aluminum-copper issue that so many other units have. Yay!!! Wife and I are going back and forth about replacing the coil or just forking over the money to replace the whole system.

I had a similar issue recently. The A/C guy had some kind if freon detector that alarmed when it picked up freon. Narrowed down to where the leak was. Pretty cool lil gadget.

Not picking on you in particular Mr Mom, but a few people have said this and is isn't what happened.
All coils for 50+ years have been made this way and most of them never leaked. The problem, especially in the time frame mentioned, was the blank off/support plates the manufactures all use at the ends of the return bends, those little U shaped pieces of copper on the evaporator coils.
Those plates are galvanized steel and are very thin and start rusting about 30 seconds after the system was turned on. What happens is that the rust particles collect on the tubing and coupled with the vibration from the fan act just like sandpaper and wear the tubes out.
That is why it takes around 8-12 months for the first leak to happen and it is so small that it may be another 6-8 months before the system has lost enough charge that the system freezes up.
At any rate, most manufactures corrected the problem, they all had it, except American Standard/Trane and Carrier, but Goodman was SLOOOW to change back... and probably wouldn't have if it weren't for the law suite, they are just that kind of shitty.

I just spoke to a Goodnan salesman. Your unit should carry a 5 year warranty from when it was installed. They did have problems with leaking indoor coils during that time. May want to attempt to find out when it was installed.

I've had to add freon almost twice a year for the last 2 years. It's become a pain in the arse What are my options? Obviously I don't know where it's leaking, but what would typically have to be repaired/replaced? And ballpark cost maybe??
Feel your pain.. I had same problem recently ... Replaced both unis for 6K

Do you have a reference for that? It's the first I've heard it, and it doesn't explain why they moved to all-aluminum or tin-plated copper, Carrier being one that moved to tin plating. I am just a homeowner, not a tech, but typical posts I've seen are like this one that talks about galvanic corrosion (Al-Cu issue):
LINK
Then there's this one that talks about formicary corrosion:
LINK
In fact, that guy said:
quote:
In most instances the leaks in these coils is not related to the rust your tech saw, but rather the leaks are in the middle of the coil in the aluminum fin covered areas.
Searching for "formicary corrosion" led me to:
LINK
Having replaced a couple of coils, I've been following this issue for probably six years, and I don't recall seeing the problem attributed to the mechanical abrasion issue you described. Inferior, thinner copper is thought to be the culprit, but not for rust grinding through it due to vibration AFAIK, but because it makes the tubing more vulnerable to galvanic and formicary corrosion. Being thinner would make it more vulnerable to mechanical abrasion, but I can't recall hearing the problem attributed to that before now.

I got a question about AC too. We have a 22 year old ac unit at our lake camp and we have put freon in it twice since memorial day, what are my options?
