No two installations are exactly the same. Several factors impact an air conditioning install timeline. These include: The quality of existing ductwork in your home and whether or not we are adding ductwork. The size and space we are working with to install your central air conditioning. Cramped spaces can increase installation time. The size and model of your AC unit. Ease of access to the installation areas. Action Furnace Comfort Advisors do their absolute best to give you an accurate quote on expected installation timelines. That said, many new AC installs can be completed within one day. But we’ll always communicate expectations before your purchase.
