I have an American Standard 5 Ton gas furnace installed in 2005. In 2007 I replaced the plumbing under the unit because the drain pipes were in bad condition. Last week we had water all over a hardwood floor and I noticed the unit was clogged again. I took the tops off the 3/4" pvc drain line and used my wet vac to suck the water, used drano and it appears to be fine now.
How do I take the cover off to look at the drain pan and coils? It is inside n my closet. So much room LOL
