Quadplex to buy a used condensor or a new HVAC?

[Robert Hernandez]

Hello BP family,

I have a quadplex that I recently purchased. One month in the condensor HVAC in one of the unit goes bad. I have a home warrarnty that the seller purchase. But, I doubt they would cover the replacement since I heard alot of horror stories.

This is the south where its very hot, the furnace/air handler is in decent shape. The technician can put a used condenser (will fill with R-22) for $500 and a new setup from around $4000.

Does anyone have experience with purchasing used HVAC? 

Any advice. I am very nervous since this is my first ever rental, I am house hacking the quadplex. The one that went bad is the one i'm living in!
