Do I need new hoses or fittings to install this condenser?

Your existing hose lines bolt directly to the new condenser at factory connection points. If hoses are cracked or leaking, replace them during install — otherwise reuse what you have.

Will I need to evacuate the refrigerant before swapping this in?

Yes. Disconnect the hose fittings, cap them immediately, and have a technician recover your refrigerant before removal. Recharge after installation using the factory spec for your year Accord.

Can I install this myself, or do I need an AC shop?

Removal and installation is straightforward if you're comfortable unbolting components and capping lines. Refrigerant recovery and recharge must be done by someone with EPA certification — that part is non-negotiable.
