Add Air Conditioning to Car: How to Install an Aftermarket AC Unit

Adding air conditioning to your car can make a big difference in your driving experience, especially during hot summer months. If your car did not come with air conditioning or you want to upgrade your existing system, an aftermarket air conditioning unit can be a great option. In this article, we will explore the process of installing an aftermarket car air conditioning unit, including selecting the right AC unit for your car, preparing for installation, and installing the unit itself.

Understanding Aftermarket Air Conditioning Units

Aftermarket air conditioning units are not factory-installed by the car manufacturer but are instead added to the car after it has been purchased. Compared to factory-installed AC units, aftermarket units may offer more features and higher performance, such as better cooling capacity and quieter operation. Some popular brands of aftermarket AC units include Vintage Air, Classic Auto Air, and Old Air Products. These units are designed to fit a wide range of vehicles, including classic cars, trucks, and newer model cars.

Selecting the Right AC Unit for Your Car

When selecting an AC unit, there are a few factors to consider. First, you should make sure the unit is compatible with your car’s make and model. Next, you should consider the cooling capacity of the unit, which is measured in BTUs (British Thermal Units). The higher the BTUs, the more cooling power the unit will have. Other features to consider include the noise level, ease of installation, and warranty. One popular type of aftermarket AC unit is the self-contained under dash AC unit, which is easy to install and does not require any external components.

Preparing for Car AC Installation

Before installing the AC unit, it’s important to inspect your car to make sure it is in good condition and does not have any leaks or other issues that could affect the AC system. You should also gather all the necessary tools and materials for the installation, including refrigerant, refrigerant lines, a vacuum pump, and an AC manifold gauge set. Finally, you should prepare the interior of your car for installation by removing any existing AC components and cleaning the area where the new unit will be installed.

Installing the Aftermarket Car Air Conditioning Unit

The installation process for an aftermarket AC unit can vary depending on the specific unit and the make and model of your car. However, the general process involves wiring the unit, connecting the refrigerant lines, and filling the system with refrigerant. It’s important to follow the manufacturer’s instructions carefully to ensure a proper installation. If you’re not comfortable installing the unit yourself, you may want to consider having it professionally installed by a mechanic or HVAC technician.

Testing and Troubleshooting the Car AC System

After the AC unit has been installed, it’s important to test the system to make sure it is working properly. You can do this by running the AC and checking the temperature of the air coming out of the vents, as well as listening for any unusual noises. If there are any issues with the system, you may need to troubleshoot the problem by checking for leaks, ensuring proper refrigerant levels, and checking the electrical connections. Regular maintenance, such as cleaning or replacing the AC filter, can help prolong the life of your AC unit and prevent future issues.

Benefits of Installing an Aftermarket Car Air Conditioning Unit

Adding an aftermarket air conditioning unit to your car can make a significant improvement to your driving experience, especially during hot summer months. By selecting the right AC unit for your car, preparing for installation, and properly installing and testing the unit, you can enjoy the benefits of a cool and comfortable ride. If you’re not comfortable installing the unit yourself, it’s always a good idea to seek professional help from a qualified mechanic or HVAC technician.
