Summer heat can make even short drives unbearable. That's where under dash air conditioning kits come in. These convenient systems offer a powerful solution for vehicles lacking factory-installed AC, bringing cool relief to your classic car, hot rod, or any vehicle without modern climate control. But choosing the right kit can be daunting. This guide dives deep into everything you need to know about under dash AC kits, helping you make an informed decision and enjoy the ride in comfort.
What is an Under Dash Air Conditioning Kit?
Under dash air conditioning kits are self-contained units designed to fit discreetly beneath your vehicle's dashboard. They typically include a compressor, evaporator, condenser, blower motor, and control panel, all packaged for relatively easy installation. These kits offer a significant upgrade over window-mounted units, providing more consistent cooling and a cleaner, more integrated look.
How Does an Under Dash AC Kit Work?
The system functions similarly to a standard car's air conditioning system. The compressor compresses refrigerant, raising its temperature and pressure. This hot, high-pressure refrigerant then flows through the condenser, where heat is dissipated into the outside air. The now cooler, liquid refrigerant flows through the expansion valve, which lowers its pressure and temperature. This low-pressure, cold refrigerant enters the evaporator, absorbing heat from the air inside the vehicle and cooling it. Finally, the cooled air is circulated by the blower motor through the vents under your dashboard.
What are the Advantages of Under Dash AC Kits?
- Improved Comfort: The most obvious advantage is significantly improved driver and passenger comfort, especially during hot weather.
- Discreet Installation: These kits are designed to fit neatly under the dash, maintaining a factory-like appearance.
- Effective Cooling: They provide effective cooling for smaller vehicle cabins, offering a noticeable improvement over alternative cooling methods.
- Relatively Easy Installation: Compared to installing a full AC system, under dash kits often offer a simpler installation process. However, some mechanical aptitude is still usually needed.
- Cost-Effective Solution: They are generally a more affordable option than retrofitting a full factory-style AC system.
What are the Disadvantages of Under Dash AC Kits?
- Limited Cooling Capacity: The cooling capacity of these kits is typically less than full-size systems, making them more suitable for smaller vehicles.
- Potential for Reduced Legroom: The size of the unit can sometimes reduce legroom, especially for taller drivers.
- Installation Complexity: While relatively easier than a full AC system, installation can still be complex and time-consuming, potentially requiring professional assistance.
- Maintenance: Like any AC system, under dash units require periodic maintenance, including refrigerant recharging and component checks.
How Much Does an Under Dash AC Kit Cost?
The price of an under dash AC kit varies greatly depending on the brand, features, and cooling capacity. You can expect to find kits ranging from a few hundred dollars to over a thousand. Research different brands and compare prices to find the best value for your needs and budget.
How Difficult is it to Install an Under Dash AC Kit?
The difficulty of installation varies depending on the specific kit and your mechanical skills. Some kits are designed for easier installation than others. While some individuals with mechanical experience can handle the installation, others might prefer to have it professionally installed to ensure proper functionality and avoid potential issues.
What Size Under Dash AC Kit Do I Need?
The appropriate size depends on the size of your vehicle's cabin and your cooling needs. Larger vehicles or those with more significant heat loads may require kits with higher BTU ratings. Consult the manufacturer's guidelines to determine the right size for your specific application.
What are the Best Brands of Under Dash AC Kits?
Several reputable brands manufacture under dash AC kits. Research reviews and compare specifications to find a reliable and suitable kit for your vehicle and needs. Remember that the “best” brand will depend on individual requirements and preferences.
This comprehensive guide provides a solid foundation for understanding under dash AC kits. Remember to thoroughly research and choose a kit that aligns with your vehicle's specifications and your budget. With careful planning and installation, you can enjoy cool comfort on the road, no matter the weather.
