Greetings, Tammy! And welcome!
'3 weeks in and going very slow'... I'm guessing the heat is at least one factor? It is for us. We're both cheering October on. It can't get here fast enough.
Regarding your AC, a couple links for you. The first is a question I asked about AC removal (and the great answers I received), the second an excellent thread about why you should STRONGLY consider keeping it.
The only thing that gave us trouble removing the units was the hose fittings were heavily corroded on our front evap/blower unit. After trying everything I could to remove them (I got one!), I ended up cutting the other hose, so when I put her all back together we'll have to source a new hose assembly. But everything else came out clean, and we taped it all off so we can re-install later.
