Does this condenser include new o-rings and seals?

The assembly itself is new and factory-sealed. You'll want fresh o-rings and lubricant for the connection points during installation — standard practice when replacing a condenser, and they're inexpensive add-ons.

Will I need a recovery machine or can I DIY this swap?

You'll need to have the system recovered by a shop with certified equipment before removal — it's required by law. The swap itself is straightforward, but the refrigerant handling is the part that requires a pro.

Does this fit the factory mounting brackets?

Yes, it uses the factory mounting points and bolt pattern. No brackets or adapters needed — slide it into place and secure to the existing hardware.
