Custom Under Dash AC Systems
O2 Cool Manufacturing designs custom automotive under-dash evaporator units to specifically cool the front seating area in numerous types of vehicles. We offer two configurations for these units:
- Standalone evaporators function independently and provide cooling exclusively.
- Integrated systems combine cooling and heating capabilities, eliminating the need for separate units.
Our dash-mounted units work well in conjunction with other ceiling, rear, or under-seat evaporators to maximize the vehicle’s HVAC performance. This targeted approach is particularly useful in vehicles where the driver’s comfort is critical to productivity and safety while other cabin areas don’t have the same cooling requirements. Integrated dash evaporators also can play a key role in windshield defrosting by removing moisture from the ambient air.

What Benefits Do Custom Under-Dash A/C Systems Offer?
In addition to saving space, our custom in-dash A/C systems come with the following benefits:
- Tailored Cooling Solutions: We can calibrate in-dash evaporators to focus cooling on the front cabin while minimizing power usage elsewhere.
- Easy Installation: Custom in-dash units are sometimes easier to install than other a/c systems, as they don’t require significant dashboard modifications and can often be incorporated into a factory heater assembly.
- Aesthetic Customization: We can customize the design to blend seamlessly with the vehicle’s interior.
Who Uses Under-Dash Evaporator Units?
Anyone who needs focused driver-area cooling in their vehicle could benefit from under-dash evaporator units, including:
- Commercial Vehicle Operators: Trucks, delivery vans, construction vehicles
- Heavy Equipment Operators: Bulldozers, loaders, forklifts
- Transportation equipment: School and transport buses, RV’s, limos
Dash mounted A/C systems can also be installed anywhere attention is needed to keep workspaces or passenger areas cool.
What Conditions Require Under-Dash A/C Evaporators?
Under-dash A/C evaporators are ideal in vehicles with tight space constraints as they don’t take up valuable interior room. They’re also beneficial for retrofits and custom installations in vehicles without factory air conditioning. Hot climates and harsh working conditions can use targeted air conditioning to stay cool and reduce heat stress in desert, tropical, or industrial environments.
