If significant ductwork modifications or repairs are required, that adds to the expense. The complexity of the installation, such as attic or crawl space access, also plays a role. The brand and model of the AC unit itself will also impact the overall price.

Then, they prepare the site for the new unit, ensuring it's level and secure. The refrigerant lines are connected, and the electrical wiring is completed.
