What belongs in an AC replacement quote?
The equipment is only one part of the project. A complete quote explains the installation and the handover.

Identify the full system
Ask for model numbers for each proposed component and an explanation of how the system was selected for your home. Confirm whether ductwork, controls, drains or other existing components need attention.
Understand what is included
The written scope should address removal, installation, required connection work, startup and cleanup. Ask about any necessary permits, inspections and registration steps without assuming they are included.
Plan the handover
Request operating instructions, maintenance requirements and written warranty documents. Confirm which party handles manufacturer registration, which parts and labor are covered, and how you arrange service afterward.
