This step can take a few days, depending on the complexity of the project, and involves the contractor outlining all costs and services in writing.
• Permits: Obtaining necessary permits is essential and can add time to the process. The contractor will handle this, but approval times vary by location, potentially adding a week or more. The contractor submits the necessary paperwork to the local authorities, and the approval time depends on the local government's efficiency.

Timeline: This phase can range from a few days to a couple of weeks, contingent on contractor availability, the complexity of the project, and permit processing times.

AC Installation Timeline

Installing a new air conditioning unit typically involves the following steps:

• Removal of the Old Unit: The old AC unit is disconnected and removed, which takes an hour or two. This includes safely disconnecting electrical and refrigerant lines.
