Hey Dan,
If you're reasonably capable with a wrench I would change it my self. I just did mine a while back. Had a shop evacuate the Freon and I took it from there. You better figure about 3-4 hours for sure. Some folks just tip the radiator and condenser back toward the engine which they say is faster. I didn't do that I took it straight up from the top. You have to loosen the cross member and tilt it back then the condenser will slide upwards. If you're going to take the cross member completely out I think you have to remove the headlights.
If you're short on patience and time take it to the shop - otherwise you can save yourself some money.
Also, make sure you replace the line washers which are the small metal/rubber insert washer which go between the lines and the receiver block
on the condenser.
If it the new refrigerant R1234YF (2017 +) be ready for sticker shock when you recharge. The shops around me wanted between $400-$700 just to recharge. I went ahead and bought all the left hand thread gauges and adapters which accommodate 1234. I bought the cans of refrigerant at Advance Auto - $44.00/can. You can get discount codes which should save you 20% or so.
Considering the condenser, gauges and refrigerant I am into for about $425.00.
Hopefully this is helpful.
