Will this mount to my factory AC lines without adapters?

Yes—this condenser connects directly at the factory refrigerant ports. You'll need to have your system evacuated and recharged by an AC shop before running it, since opening the system always requires recapture of old refrigerant.

Do I need to flush my system before installing this?

Flushing is best practice when replacing a failed condenser, especially if internal debris circulated through your old unit. Talk to your AC technician—they'll assess whether your system needs it based on how the original condenser failed.

What if the condenser doesn't hold refrigerant after I install it?

Most AC issues after install trace back to evacuation and charge procedure rather than the condenser itself. Work with a certified AC tech who has the proper recovery and charging equipment—DIY AC work typically voids any warranty on the condenser.
