AC Replacement - Buy it myself or buy from the company?

[Zane Cress]

The dreaded compressor death on an old AC unit is forcing me into a full system upgrade. It's a smaller condo that uses a 2 ton unit. I'm sure the quote to replace will come in at $5-6k. I'm thinking about buying a unit from Lowes or Home Depot myself and then finding someone to install for me. I have replaced 3 units in these condos so I know what systems to go for. Anyone had luck doing it this way? I am probably selling this unit next year so I'm not looking to go top of the line on a rental condo.
