Choosing the Right Advent Air RV Air Conditioner (or other AC)

Picking the perfect RV air conditioner isn’t a one-size-fits-all situation. Here are a few tips to guide your decision:

1. BTU Capacity: Consider the size of your RV. Smaller units (under 25 feet) might do well with 10,000-13,500 BTUs, while larger rigs or those in extreme heat will benefit from 15,000 BTUs or more.
2. Power Source: Most units are 115V AC, but 12V options exist for off-grid flexibility. Make sure your RV’s electrical system can support the chosen unit.
3. Ducted vs. Non-Ducted: Check your RV’s existing setup. Ducted systems distribute air through ceiling vents, while non-ducted units blow air directly from the rooftop unit.
4. Noise Level: If quiet operation is a priority, look for features like variable speed compressors or brushless motors.
5. Durability & Features: Consider material quality, weather resistance, and additional features like heat strips, smart controls, or enhanced cooling technologies.
6. Compatibility: If you’re replacing an old unit or integrating with existing systems (like Dometic thermostats), ensure the new AC or an adapter kit is compatible.

FAQ Section

Q1: What does BTU stand for, and how much do I need for my RV?
A1: BTU stands for British Thermal Unit, a measure of cooling power. Generally, a good rule of thumb is 1,000 BTUs per 50 square feet. For RVs, 10,000 BTUs might suit a smaller travel trailer, 13,500 BTUs is common for medium-sized RVs, and 15,000+ BTUs is ideal for larger motorhomes or those in very hot climates.

Q2: Can I install an Advent Air RV air conditioner myself?
A2: While some handy RVers do install their own AC units, it typically involves electrical wiring, sealing the roof opening, and safely lifting a heavy unit onto the roof. If you’re not comfortable with these tasks, professional installation is recommended to ensure safety and prevent leaks.

Q3: What’s the difference between ducted and non-ducted RV air conditioners?
A3: A ducted system distributes cool air through a series of vents in your RV’s ceiling, offering more even cooling. A non-ducted system blows air directly from the ceiling assembly beneath the rooftop unit, usually offering quicker cooling to the immediate area. Most Advent Air units offer compatibility for both.

Q4: How can I make my RV air conditioner more efficient?
A4: To boost efficiency: park in the shade, keep windows and vents closed, use reflective sunscreens on windows, ensure your RV is well-insulated, clean your AC filters regularly, and consider insulating your rooftop AC’s ducting if you have a ducted system.

Q5: Are 12V RV air conditioners good for off-grid camping?
A5: Yes, 12V RV air conditioners are specifically designed for off-grid use as they run directly off your RV’s battery bank (or solar system). However, they generally have lower BTU capacities than 115V AC units and require a robust battery setup to run for extended periods.

Q6: How often should I clean my RV air conditioner filters?
A6: It’s a good practice to clean your RV air conditioner filters every 2-4 weeks during regular use, or more frequently if you’re traveling in dusty environments. Clean filters ensure optimal airflow and cooling efficiency.

Q7: Can I replace an older Dometic or Coleman unit with an Advent Air RV air conditioner?
A7: In many cases, yes! Advent Air units are often designed to fit standard 14.25″ x 14.25″ roof openings, which are common across many RV brands. However, wiring compatibility can sometimes be an issue. Adapter kits, like the one reviewed, exist to bridge these gaps and make the conversion smoother. Always check product specifications and compatibility charts.
