here are some of the pictures. I am thinking of removing the water pipe, the duct tape and try to open it up as I have done it a few days ago. Then, I will try to remove the evaporator carefully so that the gas pipe/chemical pipe that is connected with the outdoor condensor won't get broken or bend tooo much ending up more hazardous situation.
What do you think? I need some information. This is a central air Air conditioner and Heater Unit for sure. Does the air pass through the filter or not is my main concern.
Thanks a lot in advanced!
