How can I fix a leaky A/C evaporator?
Any working coil is going to sweat, or it isn't working.

You need a pan or a properly ducted return that will catch the drips and protect the drywall, or a combination of both.

If it still functions, you only need a new coil if the drain tray is cracked. Even then, the pan itself might be a 'simple' replacement part.



"I read on the manufacturer's website (Bryant) that if the installation is on the first floor then a secondary drain pan must be installed." – Hemant Patel
