Powerful, Quiet Cooling

The FreshJet 5's 11,000 BTU capacity provides fast, efficient temperature control on warm travel days, while its improved airflow design cools your interior more effectively than the units it replaces. It also runs noticeably quieter — reducing interior noise by up to 9 dB — so you get the cooling you need without the constant drone. (Not sure how much cooling capacity your rig needs? Our RV air conditioner BTU sizing guide walks you through choosing the right unit by RV type.)

A Direct Penguin II Upgrade

Designed as a direct replacement for Dometic Penguin II air conditioners, the FreshJet 5 makes upgrading straightforward. Its low-profile 10.5" height improves roof clearance and gives your rig a clean, modern look, while reducing wind drag on the road. A built-in hard start feature supports reliable startup, and a durable steel base with mechanical controls is built for long-term dependability.

Flexible Installation

The FreshJet 5 works with both ducted and non-ducted systems, giving you flexibility to match your RV's configuration. Every unit comes with a pre-installed roof compression gasket on the base, creating a proper seal between the AC and your RV roof for a secure, leak-resistant installation.

Please note: Depending on your setup, you may need a replacement air distribution box and/or control kit. We carry those as well — they're linked on this page, or reach out by chat, text, or call if you need help confirming what you need.
