How Long Does AC Installation Take? A Step-by-Step Timeline

When the temperatures rise in Texas, installing a new air conditioning (AC) system can be one of the best decisions you make for your home’s comfort. However, one of the questions homeowners often ask before the process begins is: How long does AC installation take? The time required for an AC installation depends on several factors, including the type of system, the complexity of the installation, and the condition of your existing system or ductwork. In this article, we’ll break down the typical timeline for AC installation, so you know what to expect when it’s time for your system upgrade.

1. Initial Consultation and Assessment (1–2 Hours)

Before any installation begins, you’ll need an initial consultation with your HVAC technician. This is the first step in understanding your needs, assessing your home, and recommending the most suitable AC system for you. Here’s what typically happens during this phase:

1. System Assessment: The technician will evaluate your current system (if replacing an old one), inspect the ductwork, and determine the correct size of the AC unit based on your home’s square footage and insulation. 
2. Proposal and Estimate: After evaluating your needs, the technician will provide you with a detailed proposal, including the model options, pricing, and an estimated timeline for installation. 
3. Scheduling: If you approve the proposal, you’ll schedule a date for the actual installation. Many companies, like Texas Air Authorities, offer same-day appointments or convenient scheduling options for installation. 

2. Preparation for Installation (1–2 Hours)

On the day of installation, your technicians will arrive at your home and prepare for the job. This phase includes:

1. Turning Off Power: For safety, the power to your current AC unit and the electrical system will be turned off. 
2. Equipment Delivery: If the unit hasn’t already been delivered, the technicians will bring the new system and tools required for the installation. This includes refrigerant, ductwork materials (if needed), and any other necessary parts. 
3. Protecting Your Home: Before starting, the technicians will lay down protective coverings or drop cloths to prevent damage to your floors and furniture. 

3. Removal of Old Unit (1–2 Hours, If Applicable)

If you’re replacing an old unit, the next step is to remove the existing system. Depending on the size and complexity, this process can take anywhere from 1 to 2 hours.

1. Disconnection: The technician will disconnect the power, refrigerant lines, and ductwork connected to the old unit. 
2. Removal: Once disconnected, the team will remove the old AC unit and any outdated components. If you plan to recycle the old unit or have it disposed of, the technicians can assist with that as well. 

4. Installation of the New AC Unit (4–8 Hours)

This is the main phase of the installation, where the new air conditioning system is placed and connected to your home’s infrastructure. The length of time for this step can vary depending on several factors, including the complexity of the installation and whether additional work is needed, such as new ductwork or electrical upgrades.

1. Placing the New Unit: The team will first position the new AC unit in place. This includes mounting the indoor unit (evaporator coil) and the outdoor unit (condenser). 
2. Electrical Connections: Technicians will then connect the electrical components, ensuring that the system is properly wired to your home’s power supply. This may require installing a new circuit breaker, depending on the size of the unit. 
3. Connecting Refrigerant Lines: Refrigerant lines connect the indoor and outdoor units. These lines need to be properly sealed to prevent leaks and ensure the system works efficiently. This process may take some time as precision is key. 
4. Ductwork Installation (if necessary): If your existing ducts are outdated or improperly sized for your new system, the technicians may need to install new ductwork or modify the existing one to ensure optimal airflow. This could add an extra 1–2 hours to the installation time, depending on the extent of the changes required. 
5. Thermostat Installation: If you’re upgrading your thermostat to a more energy-efficient model (such as a smart thermostat), the technician will also install and program it. This typically takes about 30 minutes to an hour. 

5. System Testing and Calibration (1 Hour)

Once the new system is installed, it’s time for the technicians to test everything and ensure it’s functioning properly:

1. System Check: The technicians will turn the system on to check for any immediate issues. They’ll look for air leaks, check the refrigerant level, and ensure that the unit is cooling effectively. 
2. Temperature Calibration: The technician will calibrate the thermostat and make sure the AC system is set to the optimal temperature and performance levels. 
3. Final Inspection: The final step includes checking all safety features, such as the circuit breakers, ensuring that everything is running smoothly, and confirming that there are no leaks in the refrigerant lines. 

6. Cleanup and Final Walkthrough (30 Minutes–1 Hour)

After the installation is complete, the technicians will clean up the area and ensure your home is left in the same condition as when they arrived. They will remove all debris, packaging materials, and tools from the job site.

1. Final Walkthrough: The technician will walk you through the system’s features, explain how to use your new thermostat, and answer any questions you may have about maintaining your system. They may also provide tips for optimal energy use and comfort settings. 
2. Warranty and Maintenance: Finally, the technician will go over the warranty and provide details on future maintenance needs. You’ll also be informed about available service plans to ensure the long-term efficiency and lifespan of your new system. 

How Long Does AC Installation Take?

In total, AC installation typically takes between 5 to 8 hours, but this can vary depending on the complexity of the project. A basic system replacement might take less time, while new installations with added components, like ductwork or electrical upgrades, may require a full day or more.
