When it comes to installing an air conditioning unit, many homeowners often wonder how long it takes to install an AC unit. Typically, the process can range from four to eight hours, but several factors can extend this timeline, sometimes significantly.

Factors Influencing Installation Time

The first step in any air conditioning installation is the in-home estimate. This crucial phase involves assessing your home’s specific cooling needs through a manual J load calculation. This calculation is essential for determining the optimal size of the air conditioner needed, considering how much heat your home absorbs in summer or loses in winter.

Installation Day Dynamics

On the day of installation, the actual time needed can vary. The typical time it takes to install a new AC unit ranges from four to eight hours. This period is contingent upon factors like the size and configuration of the existing system, local weather conditions, and the accessibility of the installation site.

Technicians will need access to both inside and outside areas and may start by protecting your floors with drop cloths while they remove the old unit. Capturing and properly disposing of the refrigerant takes time due to environmental regulations. Removing the old components typically adds about an hour to the process.

Setting Up the New System

Introducing the new system involves several steps. First, the outdoor unit is placed on a gravel bed to ensure stability and proper leveling. Simultaneously, the indoor evaporator coil is fitted with the furnace or main air handling unit. This setup can take between 30 minutes to an hour and a half. The next phase includes running and brazing the new line set, which connects the outdoor and indoor units.

Final Steps and System Activation

Wiring the system correctly is crucial as it enables the air conditioner to communicate with your home’s heating system and switch between modes as needed. This step takes around an hour. Following the wiring, the system must be charged with refrigerant and pressurized, a process that could take another hour or two, depending on the system’s size.

Once charged, the system is turned on, and the installation team conducts a commissioning process to confirm everything is working correctly. This step is vital for ensuring the efficiency and longevity of your system.
