Give him some time, that 75 lead list will begin to condense and concentrate into better results. 

You can by the condenser online but it won't come charged because the AA coil is a separate part that sits on the furnace.  

It should be up for another 12h or so under my handle HomestarKevin.Disclaimer: I'm not real proficient at Periscoping yet so I may try again sometime and condense the information a bit.

If condensation has built up under the plastic your basement is not currently sealed and you'll have moisture problems you'll want to address (tiles, vapor barriers,sumps).

Most of the ones we manage have flat top roofs with condenser units on top.

AC condenser went out in a unit I closed on this month...Property management co submitted bid to do the replacement for $5k in-house (for condenser and evaporator coil to bring up to 410A from R-22).  

@Chris Sullens you might want to out a cage on your a/c condenser if you haven't already done so.

It sound like it is cooling, just not very well,   Could be a dirty evaporator coil, a dirty condenser coil, dirty filters, or it might need Freon.  

Kind a misleading metric to chase, like mentioned in almost every area it's going to come down to a more condensed neighborhood at best, at worst it'll be block by block.neighborhoodscout is a interesting website, haven't used them in a long time (I think it used to be free) but they might be of use to you.

I'll take a shot but keep in mind I have no clue what your house is like but good educated guess would beKitchen - $8000.002 Baths - $7000.00Flooring mix of carpet & ceramic tile - $4500.00Electric (meaning light fixtures and outlet/switches) - $2500.00Plumbing (meaning finishes) - $1500.00HVAC (meaning new 80% furnace/3 ton condenser) - $4000.00Landscaping - $1000.00Siding - $7000.00Don't forget painting - $3000.00And you have a $500.00 cushion lol...not bad for a guess but if I was forced to do that this is how I would budget it.
