Will this work with my existing AC lines and fittings?

Yes — this condenser uses factory connection points and refrigerant port sizes. Your existing hoses and fittings bolt up without adapters or modification.

Do I need to flush the system before installing this?

Flushing is recommended if your old unit failed or leaked — trapped debris can damage the new condenser. If you're unsure whether debris is in the system, have a tech pressure-test it first.

What if the new condenser doesn't cool after install?

Most cooling failures after condenser replacement stem from low refrigerant charge or air in the lines. Have the system evacuated and recharged by an AC-certified technician — this is not something you can do at home without proper equipment.
