So I thought i'd post this here because it might help someone in the future.
AC/furnace is inside the garage in utility closet. Had the AC running the other day and the garage door open most of the day which is unusual for me. The garage attached to the house is just to park the car in. The detached one is where all my tools and tractor and all that stuff are located.
So i had the door open all day and came around after 5 or 6 hrs and noticed water all on the garage floor. All coming from underneath the closet.
So i go in there and both ducts leading from the AC are sweating BAD. I'm talking gallons and gallons of water leaking down the furnace onto the floor. I'm wondering why. Then i realize i had the door up all day, and it was pretty hot so i was thinking the heat, mixed with the cold ducts = condensation.
Next day I get home from work and more water on the floor. Now i'm thinking something major is wrong. I'm thinking water line above the unit is leaking or the hot water tank is somehow leaking....who knows. Maybe a refrigerant leak somewhere in the coil. All i see is $$$$ flashing before my eyes.
So then i get to reading and decide i need to insulate the duct work better. So i do that. The next day, no water in the floor. But it was only 70 outside. Little did I know, my wife turned the AC off that day and opened all the windows. So of course it didnt sweat that day. But in my head I thought i fixed it.
Fast forward 3 or 4 days of 70 degree weather to Saturday when it hit 85. Came home to more water than ever in the garage floor. So i start tearing things apart on the furnace/ac unit to see if i can see whats wrong. I have the blower off and the exhaust fan off and I see where water is coming from everywhere. Its not obvious. Then i take the front off the AC coil and peek in there and the drip pan at the base is overflowing.
Ended up being a stopped up drain line from the drip pan to the floor drain. About 1/2" of rust had somehow gotten stuck inside the PVC drain and was backing everything up. So $1 and 2 1" couplers later, I have everything fixed.
I always think the worst and never check the simple stuff first. Maybe on day i'll learn. lol I'm just glad it wasn't anything major. The unit is over 30 yrs old and its on its last legs anyway. I just hadnt planned on replacing it this year. Glad it only cost me $1 for some PVC.
Maybe this will help someone in the future.

Used to drag an air line in from the service truck and blow the line with some compressed air to get the stuck lizard back out of the line
