Furrion Chill Replacement RV Air Conditioner, Chill 15,500 BTU Rooftop Air Conditioner (White) with Conversion Kit for Coleman/Dometic/Advent Air Distribution Box - EACCNV3-AM Review (2026)

What is included

This listing pairs a Furrion Chill 15,500 BTU rooftop air conditioner in white with a conversion kit built to mount it onto an existing Coleman, Dometic, or Advent air distribution box. The kit supplies the wire adapter and four mounting brackets needed to connect the new rooftop unit to the ceiling assembly and thermostat already installed in the RV, so the interior vents and control panel stay the same while the rooftop hardware is upgraded. This is meant as a capacity upgrade path for owners whose existing ceiling box is still in good shape and who mainly need a stronger, more efficient unit on the roof.

Cooling capacity and dual-fan design

At 15,500 BTU, this is the highest capacity unit in the Chill conversion lineup covered by this site, built for RVs that need more cooling power than a standard 13,500 BTU unit provides, such as larger travel trailers or units with a lot of window glass. Like the rest of the Chill line, it uses two separate fans with their own motors rather than one shared fan, which Furrion positions as moving conditioned air through the cabin faster than single-fan designs. A built-in start capacitor stores energy to help the compressor start reliably even on a generator or campground pedestal that is not delivering full power.

White shroud advantage

Choosing white over black gives this unit a real functional edge in hot, sunny climates, since a reflective white surface absorbs less solar heat than a dark one. That keeps the internal components of the air conditioner running cooler on a hot afternoon, which can translate into slightly better cooling efficiency compared to an identical black unit sitting in the same sun. For RVers who spend significant time in hot regions or park with limited shade, the white shroud is generally the more practical color choice, on top of matching the factory white finish still common on many RV roofs.

Power draw and roof weight considerations

Higher cooling capacity comes with a higher electrical startup load, and 15,500 BTU units draw more power at startup than smaller 13,500 or 14,500 BTU models, which matters for RVers running on a smaller generator or a campground pedestal with limited amperage. The built-in start capacitor helps offset that by assisting the compressor start rather than pulling everything from the incoming power line at once, but it does not eliminate the need to check your generator's rated surge capacity before relying on this unit off shore power. The unit itself is also heavier than smaller rooftop air conditioners, so confirming your RV's roof structure can support the added weight is worth doing before ordering.

Who should buy it

This is the right pick for owners of larger RVs with an existing Coleman, Dometic, or Advent air distribution box who want the strongest cooling capacity available in the Chill conversion series, especially if they spend time in hot, sunny climates where the white shroud's heat reflection is an advantage. It is a less practical choice for RVers relying on a small generator without checking its surge rating first, or for smaller rigs that do not need 15,500 BTU of cooling capacity in the first place, where a lower capacity unit would draw less power for adequate results.
