Portable AC unit in my RV?

Yep, you can use a portable AC unit. I used to run a 7,000 BTU Whynter Portable AC in mine. I have a 50 amp RV so power wasn’t an issue, but somethign to keep in mind depending on your setup. Also, you’ll want a dual hose unit (and you’ll need somewhere to vent the hoses to the outside. mine came with a window kit). And you’ll have to continually drain the pan if it doesn’t have a pump that drains it out the window.

It was a little noisy. And the fan runs whether its cooling or not, so it always makes noise.

All that said, it worked really well!

@ia_camper is right on the money.

I would also suggest, if you haven’t already:

1. Service your AC: Have your RV air conditioner serviced at least once a year, ideally before the hot weather season begins.
2. Regularly inspect the unit: Routinely check your A/C unit for any pests, nests, or debris build-up, and clean away any that you find. Check all the bolts and tighten them as necessary to prevent rattling & potential damage.
3. Clean the filters regularly: Maintain adequate airflow and improve efficiency by cleaning your air filters regularly, ideally every month during peak season or every few months otherwise.

It could just be your existing AC unit needs a little TLC.

Beyond your AC, here are a few tips to help keep your RV cool:

1. Use Reflective Window Covers: Invest in reflective window covers or sunshades to block out the sun’s heat.
2. Park in the Shade: Whenever possible, park your RV in a shaded area to reduce direct sunlight exposure.
3. Awning: Use your RV’s awning to provide shade over windows and doors.
4. Start Cooling Early: Begin cooling your RV early in the day before it gets too hot.
5. Use Portable Fans: Enhance airflow and provide additional cooling with portable fans.
6. Cook Outside: Use an outdoor grill or camp stove to avoid increasing the indoor temperature.

RVs are notoriously hard to keep cool in extreme heat, but maybe these tips will help save you hundreds on buying a portable unit.
