AC Experts out there?

[fishhu1968]

I've had to have 2 AC units replaced within the last year. Now I have 2 more!! that are leaking freon. All within the same building. They are 12-13yrs old which I know is not brand new, but find it odd that they would all start leaking freon almost simultaneously. I've even gotten a 2nd opinion about the leaks because I thought I may have been getting "scammed". They all are on a regular 6 month service contract. We are in a high humidity area if that makes a difference. Any ideas on why this is happening or suggestions on what we could do in the future to prevent this?

And you are 100% certain it is freon that is leaking and is just now condensation leaking because the plug/drain area is clogged???

Yes, both were completely out of freon. Luckily the temps here have been mild so the other units have been keeping up. We have 7 total in this building, but come summer we need all of them going 24/7.

You wouldn't by chance be on a well with sulfur water would you? The sulfur gas in the water will attack the coils. Do you know where the units are leaking from? If its just a bad joint they can be brazed and recharged pretty easy.

City water. Only know its the coils that's leaking. 2 separate companies have confirmed it. They both say it's more cost effectifve to change out the whole air handler than just the coils. This will be 4 units in the last year in a building with 7 total. These latest 2 were found during their 6 month servicing. At this point, I'm ready to blame it on the air freshners!!! LOL
