Hello! I am so grateful that this forum exists. We have a split style central air conditioner / heating system. It uses gas for the heat and electric for the AC. We have noticed over the last two weeks that our house was not cooling as well. The problem has progressively worsened. Last Friday the temperature indoors was actually rising with the AC running. We cleaned the outside unit well. I also cleaned the fan inside the inner unit. I had trouble locating the coil in the AC unit. I planned to clean this also. I read other posts prior to looking for it, but I had trouble finding the coil by following the duct work as suggested in another post. Maybe our unit is different - or I just missed it?! The make of the unit is WELBILT, model no. 900803 serial no. 100614 Bonnet cap. 64000 Input BTU/hr 80000 I followed the instructions at the beginning of this forum and searched for the maker online. I am guessing this unit is quite old, I had no luck finding any info on Welbilt cooling/heating systems. I did however stumble upon a memo of sorts stating that this heating/cooling company no longer exists. I would like to try and trouble shoot this problem myself. Any suggestions, advice, or instruction on where to find the coil or other ideas of what the problem could be are welcome and extremely appreciated!!! :) I live in FLORIDA and this is not the best time of year for the air conditioner to malfunction! Thanks!

This morning I notice about a half inch of frost on the bigger pipe going into the furnace. About 4 inches of the pipe isn't insulated before it goes in and that is what if frosted up. Do I have a problem? Thanks. Mary
