Hi, Thanks to your site I have determined the ac drainage is most likely the reason I am getting interior flooding . Could you estimate a cost associated with this repair. I have seen tips to unblock drain hose but dont feel comfortable trying this myself. thanks for your help

Start with the outside drain hose. Make sure it is connected to the A/C plenum. It is easy to clean just be carefull you don't blow high pressure air as it could cause other damage. There is a good chance you have a cracked hose.

It is a tough head angle but after you remove the hose and use a pipe cleaner, poke it inside the case hole and make sure it is clean.

Confirm the outside A/C drain hose is connected to the plenum. Remove the hose, clean it and the case opening with a pipe cleaner, and avoid high-pressure air. Also check for a cracked hose.
