What I find to usually be the biggest difference is the company that’s willing to vacuum out the system and only replace the compressor/condenser half and install r410a freon.

Property required modest cosmetic updates (fresh paint, vinyl plank flooring), new electric stove, gas line repair, and HVAC condenser replaced.What made you interested in investing in this type of deal?

So if a GC is involved at all, that means the job is large enough that the Subs would not pull permits or be involved in the inspection process....Replacing a Water Heater or AC Condenser would be different...no GC involved or needed, so the Sub would be responsible for the permit and inspections.

Yes, pee is so corrosive that it destroyed the condenser coil.

If it is under-vented you can get condensation and mold on the under-deck and rafters.

By replaced I mean new handler/condenser, not sure if the ducts are original or not.

So, once I go under contract, I then immediately schedule my inspections which include roof inspection, plumber (check sewer lines and fresh water lines), HVAC (check AC condensers, heating units, boilers and chillers - if applicable), and if anything looks suspect, a foundation expert.

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.

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).
