DEVALLEY A/C Air Conditioning Evaporator
DEVALLEY offers a 2-in-1 heating and cooling evaporator designed for universal installation in RVs, pickups, trucks, and boats. It features 24 aluminum tubes, 8 copper tubes, and a 4015W cooling capacity with 369 CFM airflow. Four air ports and a 3-speed wind control allow customizable comfort. The pure copper motor supports long service life, with a rated power of 80W and a high-speed 3800 RPM. The unit’s compact design makes it suitable for small footprints in under-dash or cargo-area installations, delivering reliable auxiliary climate control.
Saihisday 12V Under-Dash A/C Evaporator
The Saihisday under-dash evaporator is designed to add a cooling system to vehicles without factory A/C. It provides a 12V power draw (7.6A) with specific cooling and heating capacities: heating up to 3619 kcal/h (BTU 14360) and cooling 4107 kcal/h (BTU 16297). Its universal design targets cars and trucks with a compact form factor, enabling retrofits in tight spaces while offering a clear thermal upgrade to the vehicle interior.
RV Air Conditioner 12V Rooftop (outequip)
This 12V rooftop unit from outequip delivers 10,000 BTU of cooling for RVs, trucks, and vans, with a built-in heater offering 4,500 BTU for mild weather support. The configuration emphasizes quick cooling in smaller spaces and durability with UV-stabilized ABS housing, EPDM foam gaskets, and a zinc-coated condenser to withstand weather and road conditions. It provides a compact, all-in-one option for owner-operators seeking fast, reliable climate control on the go.
Evargc 12V Compact Hydronic Heater
The Evargc hydronic heater is a compact 12V unit with a front-vented, 3-speed fan delivering up to 8500 BTU of heat. It is designed to connect to a vehicle’s water system, requiring a 5/8″ (16mm) inner-diameter hose for water input. The heating output depends on the vehicle’s water temperature, which means it can work as a supplementary heat source when paired with a suitable water supply. This makes it suitable for operators seeking an integrated heating solution rather than a standalone air conditioner.
AClengda 12V Truck A/C (9000 BTU)
AClengda’s 12V truck air conditioner is a 9000 BTU split-type unit designed for trucks, RVs, excavators, and vans. It emphasizes efficiency with a thickened aluminum condenser, intelligent temperature control, low noise, and battery or engine-assisted operation. The outdoor unit uses a rugged ABS shell with protective weatherproofing, while the indoor unit features a five-outlet design with adjustable rotation for versatile air distribution. It aims to balance comfort with energy conservation in mobile setups.
32,000 BTU 24V Universal Auxiliary Cab Heater
American Cooling Solutions provides a high-capacity 32,000 BTU 24V auxiliary cab heater intended for heavy-duty vehicles. It is designed for cab environments across tractors, trucks, buses, vans, and UTVs, and includes an installation kit for straightforward setup. This option emphasizes robust heating performance in very large spaces or colder regions where extra warmth is needed to maintain driver comfort and cargo conditions during winter or cold starts.
20,000 Compact BTU Auxiliary Heater
The Eagle 20,000 BTU auxiliary heater is designed for trucks, buses, and vans, with optional floor-through connections for easy integration. It includes hardware and an installation kit, emphasizing a compact footprint while delivering substantial heat output. This unit is suitable for operators who require a reliable heat source to complement cooling systems in diverse mobile environments.
Buying Guide
Key considerations when choosing an auxiliary A/C and heating system for trucks:
- Power supply: Confirm 12V or 24V compatibility with your vehicle electrical system and available battery capacity.
- Cooling vs heating balance: Decide whether you need primary cooling, supplemental heating, or a combination, and match BTU/cooling capacity to cabin size.
- Installation complexity: Under-dash evaporators are compact but may require professional wiring; rooftop or split units can demand more mounting work.
- Durability and weather resistance: Look for UV-stable housings, corrosion-resistant components, and robust hoses/connectors for harsh environments.
- Maintenance: Consider filter access, ease of refrigerant handling, and service life of fans and compressors.
- Noise and efficiency: Evaluate decibel levels and energy use, especially for long-haul drives or sleeper cabins where quiet operation improves rest.
- Space constraints: Measure available clearance for installation, including under-dash, ceiling, or roof mounting options.
- Warranty and support: Check manufacturer coverage and access to spare parts in case replacements are needed on the road.
