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

O-rings and seals are not included with this unit. You'll want to grab a new set before install — reusing old ones is how leaks start. Most shops replace them as standard practice during condenser swap.

Will this bolt up to my factory lines and brackets?

Yes. This unit mounts at the factory connection points and works with OEM refrigerant lines. No adapters or modifications needed — it's a direct bolt-in replacement.

Do I need to have the system evacuated before removal?

Yes. Your AC system holds pressurized refrigerant — you'll need to have it evacuated by a shop with recovery equipment before you pull the old condenser. Installation will also require a proper recharge once the new unit is seated and lines are reconnected.
