Dometic FreshJet RV Air Conditioners

What is the difference between the Dometic FreshJet 3, FreshJet 4, and FreshJet 5?

The FreshJet 3 is sized for smaller travel trailers and Class B vans. The FreshJet 4 suits mid-size trailers and fifth wheels. The FreshJet and FreshJet 5 handles larger Class A motorhomes and longer fifth wheels in hot climates. All three use R32 refrigerant and run on 115V AC shore power.

Is the FreshJet a ducted or non-ducted RV air conditioner?

FreshJet rooftop units can run as either ducted or non-ducted, depending on the ceiling assembly you pair with them. For non-ducted installations with a wall thermostat, see the Dometic non-ducted ceiling assembly with wall thermostat. For heat pump models, the FreshJet 5 heat pump non-ducted ceiling assembly covers cooling and supplemental heating from one unit.

How do I match a Dometic FreshJet part number like 9610007807 or 9620017216 to the right unit?

Dometic FreshJet part numbers identify a specific BTU class, refrigerant type, color, and heat pump configuration. 9610007807 and 9620017216 are full rooftop unit SKUs, so confirm your existing roof opening (standard 14 x 14 inch), incoming voltage, and whether your rig is wired for a ceiling thermostat or wall thermostat before ordering. If you are unsure, text or call our team at 817-984-1852 with your RV year, make, and model and we will verify fitment.

Does the FreshJet need a soft start kit for 30-amp service or generator use?

A soft start kit is not required, but it is strongly recommended if you run on a 30-amp pedestal, a small inverter generator (such as a 2200W unit), or solar. Soft starts reduce inrush current at compressor startup by up to 75%, which prevents nuisance breaker trips and lets smaller generators carry the load. For related 30/50-amp power gear, see our RV plug adapters collection.

What refrigerant does the Dometic FreshJet use?

Current FreshJet rooftop air conditioners use R32 refrigerant, which has a lower global warming potential than the older R410A and improves cooling efficiency per amp drawn. R32 systems are factory-sealed; field recharging is not a DIY service. If your unit is not cooling, the issue is more often a capacitor, fan motor, or control board than refrigerant loss.

How long does shipping take on Dometic FreshJet units?

FreshJet rooftop air conditioners ship via truck freight due to size and weight, with a $99 freight charge to a residential or commercial address. Transit time runs 3 -5 business days depending on location. Inspect the carton at delivery for any signs of visible or concealed shipping damage before signing.
