Their computer-aided design and flexible duct hoses allow for the best performance. Designed to last a lifetime, the quality and attention to detail is evident in our systems.

Installation of the system is simple with their detailed step-by-step instructions. No special tools required and every system is always backed by the best tech support in the industry.

AC / Heat / Defrost:

Independent dash function. Our exclusive dash louvers provide you with powerful air conditioning that no one else on the market can touch. Restomod Air provides unmatched dehumidified defrost. Our easy defrost installation connects to the original defrost diffusers allowing for less modification in this tight space.

Direct Pass Airflow Technology:

Restomod Air evaporators are AutoCAD designed to maximize airflow using the exclusive Direct Pass technology. This gives you a greater volume of unobstructed airflow. You also benefit from larger door openings.


Keeping with the feel of the OEM controller, Restomod Air’s HUMVEE – HMMWV brand new controller mimics the stock feel, which looks greats, works perfectly, and installs in your dash with little modifications. Easy to read and clearly labeled it blends perfectly into your dash just like the original. The HUMVEE – HMMWV new controller ditches the outdated push-pull cables that came stock and goes electronic. Giving an accurate and reliable adjustment every time you want to use the system. Independent Dash and Defrost function along with a three-step blower motor are just the tip of this iceberg.

Fully Electronic:

Restomod Air was the first to convert to high-quality servomotors to open and close internal doors. We pioneered this improvement and we STILL implement it best.


All Restomod Air coils systems are engineered with carefully sized, (Largest on the market) separate A/C and Heat coils. The separate coils improve the cooling and heating capacity of the total system.

SPAL Fans:

State of the art High Output OEM style blower assemblies with internal heat sink speed controllers for thermal protection. Excellent air volume with less electrical amperage. This is very important when installing on older vehicles where the electrical systems are not upgraded to modern standards. Our HUMVEE – HMMWV system has the highest torque SPAl blower motors and largest independent coils ever, giving exceptional air volume and temperatures not matched by anyone else. This a/c system is complete, no hidden option to deal with later. And if there is ever a problem Restomod Air leads the industry in technical support.
