Product Description

The Dometic FreshJet 5 Rooftop RV Air Conditioner delivers powerful and efficient cooling performance in a compact low-profile rooftop design engineered to upgrade RV comfort. Featuring approximately 15,000 BTU of cooling capacity, this high-efficiency rooftop air conditioner provides increased airflow and quieter operation for more comfortable travel and camping experiences.

Designed for both ducted and non-ducted RV applications, the FreshJet 5 incorporates a built-in hard start system for smoother compressor startup and improved operating reliability. Its custom blower system increases airflow circulation while helping maintain more even interior temperatures throughout the RV.

Constructed with durable evaporator e-coated coils, the FreshJet 5 is engineered for long-term reliability while using less refrigerant compared to earlier-generation rooftop air conditioners. The lightweight low-profile design also improves roof clearance and aerodynamic performance without sacrificing cooling capability.

This rooftop unit is backwards-compatible with many existing Dometic and competitor air return systems, making it an excellent option for replacement and retrofit installations.

Please note that ceiling assemblies and wall thermostat controls are sold separately for new installations.

Manufacturer model and installation verification

Exact model FJX5557MBKCS: Dometic FreshJet 5 Black rooftop air conditioner with 15,000 BTU/h nominal cooling capacity and manufacturer-listed 12.8A compressor rated-load current. This is a cooling-only rooftop unit, not a heat pump. Dometic's technical table lists 115V AC, 60Hz single-phase operation. Electrical protection and fan ratings should be checked against the full model identification and current installation instructions.

Replacement fit check: Existing Penguin II replacement information in this listing is retained. Before replacing an older unit, verify the roof opening, mounting support, gasket arrangement, duct or non-ducted ceiling assembly, control-board generation and thermostat connection. Similar roof dimensions or capacity do not by themselves confirm that an existing electrical control system can be reused. Interior air-distribution equipment and control hardware may be required separately.
