Dometic RV Air Conditioners

What Dometic RV air conditioners are available in this collection?

This collection covers the full Dometic rooftop AC lineup, including Brisk II, FreshJet 3 Series, FreshJet 5 Series, and Penguin II units in 13,500 and 15,000 BTU configurations, plus the ducted and non-ducted ceiling assemblies, control kits, and replacement components that go with them. If you are running a ducted system across multiple zones, the Dometic Brisk II ducted ceiling assembly for multi-zone installations is the matching interior component.

How do I know which Dometic AC unit fits my RV?

Start with the model number on your existing unit's data plate, then confirm three things: BTU rating (13,500 vs 15,000), roof opening size (the industry standard is 14" x 14"), and whether your system is ducted or non-ducted. A 13,500 BTU unit is typical for trailers under 32 feet; 15,000 BTU is appropriate for larger coaches or hot-climate use. Always confirm your model number before ordering to make sure you get the correct fit.

Which Dometic AC works best in hot climates?

For desert and southern summer use, the 15,000 BTU FreshJet 3 Series and Penguin II 15K are the strongest performers in the Dometic lineup. They run R32 refrigerant and have higher airflow ratings than the 13,500 BTU models, which matters once ambient temps cross 95°F. If you have a non-ducted setup, pair the rooftop unit with the FreshJet 5 with heat pump ceiling assembly for non-ducted installations to add supplemental heat for shoulder-season trips.

Can I install a Dometic RV air conditioner myself?

Yes, most Dometic rooftop units are designed to drop into the standard 14" x 14" roof opening and bolt down with four corner bolts. You will need a helper to lift the unit (they weigh 75 to 95 pounds), basic hand tools, and a multimeter to verify the 120V power connection at the ceiling assembly. The ceiling assembly is sold separately and must match your duct configuration. Need help confirming fitment? Our team at United RV Parts is here to help, text or call 817-984-1852.

What replacement parts do you stock for older Dometic AC units?

We carry control boards (including the 3316348.900 series), capacitors, fan motors, thermostats, gaskets, shrouds, and wiring harnesses for Brisk Air, Brisk II, Penguin, Penguin II, and FreshJet units. Most failures on a Dometic AC trace back to a single component rather than the whole unit, so it is worth diagnosing before replacing the rooftop. Cross-reference the part number on the failed component against the listing to confirm compatibility.

Do Dometic AC units ship freight, and is shipping free?

Complete rooftop AC units ship via truck freight due to size and weight, with a flat freight charge listed on the product page. Smaller components, control boards, and accessories ship standard ground. Orders over $100 on ground-eligible items qualify for free shipping.
