RV Air Conditioner 15,000 BTU

What size RV needs a 15,000 BTU air conditioner?

A 15,000 BTU unit is sized for most full-length travel trailers, fifth wheels, and Class A motorhomes roughly 30 feet and longer, or any rig where a 13,500 BTU unit struggles in hot climates. If your RV came pre-wired for a rooftop AC, confirm the existing 14x14 inch roof opening and that your electrical system supports the higher amp draw (typically 13-16 amps on 120V AC) before ordering.

Can I replace a 13,500 BTU unit with a 15,000 BTU model?

In most cases yes, the rooftop cutout is the same standard 14x14 inch opening. The two things to verify are amperage capacity (a 15K unit pulls more current and may push a 30 amp service closer to its limit if other appliances run simultaneously) and whether you need a matching ceiling assembly for ducted or non-ducted setup. Browse the Coleman Power Saver HP ceiling assembly for ducted installations or the Dometic non-ducted ceiling assembly with wall thermostat depending on your roof configuration.

Will a 15,000 BTU RV air conditioner run on a 30 amp service?

Yes, but with care. A 15K unit typically draws 13-16 amps on startup and around 12-14 amps running, leaving limited headroom on a 30 amp pedestal once a converter, refrigerator, or microwave is also active. A soft start kit reduces inrush current up to 75% and helps prevent breaker trips on 30 amp service or when running off a smaller generator. See the Coleman RV air conditioner soft start collection for compatible kits.
