Do I need new O-rings or seals when I install this?

Yes. Replace all connection O-rings when you swap condensers to prevent refrigerant leaks. Standard practice for any AC condenser replacement.

Will this condenser work with my existing AC lines and fittings?

This unit matches factory connection points, so your OEM lines bolt directly to it. No adapters or custom fittings needed.

Should I have the system evacuated and recharged by a shop?

Yes. AC work requires proper equipment to pull a vacuum and refill with the correct refrigerant charge. Handle this at a certified shop to ensure the system holds pressure.
