How to Choose the Best RV Air Conditioner?

Choosing the right RV air conditioner requires understanding several key factors that affect performance, efficiency, and compatibility with your specific RV. Let’s break down the most important considerations to help you make an informed decision.

BTU Sizing Guide

The British Thermal Unit (BTU) rating indicates cooling capacity – higher BTUs mean more cooling power. For RVs, the general rule is 20 BTUs per square foot of living space, but this varies by climate:

RV Length	Living Space	Moderate Climate	Hot Climate	Extreme Heat
15-20 feet	120-160 sq ft	9,000 BTU	11,500 BTU	13,500 BTU
21-25 feet	160-200 sq ft	11,500 BTU	13,500 BTU	15,000 BTU
26-30 feet	200-240 sq ft	13,500 BTU	15,000 BTU	15,000-18,000 BTU
31-35 feet	240-280 sq ft	15,000 BTU	15,000-18,000 BTU	18,000 BTU
36+ feet	280+ sq ft	15,000-18,000 BTU	18,000 BTU	18,000+ BTU

Remember that bigger isn’t always better – an oversized unit will cycle on and off frequently, reducing efficiency and failing to properly dehumidify the air.

Power Requirements

RV air conditioners typically require 115V AC power when connected to shore power or generator, drawing 8-15 amps depending on BTU rating and efficiency. However, 12V DC options are increasingly available for off-grid camping:

• 115V AC Units: Most common type, requires shore power or generator. Amp draw ranges from 8-15A depending on size and efficiency.
• 12V DC Units: Run directly off vehicle batteries. Amp draw is higher (35-70A) but can operate without generator.
• Dual Power Units: Some models like the FOGATTI require both 115V for cooling and 12V for controls.

For solar or battery-powered setups, consider that 12V units like the Treeligo or Bailigo offer true off-grid capability but will significantly drain your batteries without adequate charging capacity.

3. Non-Ducted Systems: Air blows directly from a ceiling assembly. Simpler installation but can create uneven cooling.
4. Under-Bench Units: Installed under seating or cabinets. Less common, requires floor space but reduces roof weight.

Noise Level Considerations

Noise levels significantly impact camping comfort, especially during nighttime use. RV AC noise is measured in decibels (dB):

• Ultra-Quiet (45-50 dB): Similar to quiet conversation or rainfall. Best for noise-sensitive campers.
• Quiet (51-55 dB): Noticeable but not disruptive. Acceptable for most campers.
• Moderate (56-60 dB): Clearly audible, might disturb light sleepers.
• Loud (60+ dB): Similar to vacuum cleaner. May disrupt sleep and conversation.

If quiet operation is a priority, consider models like the RecPro 13.5K (59.7 dB) or TOSOT 16K (52 dB). Variable speed units like the Furrion Chill Cube maintain more consistent noise levels without the sudden on-off cycling of traditional units.

Special Features to Consider

Modern RV air conditioners offer various features that enhance convenience and performance:

• Heat Pump Function: Provides efficient heating in addition to cooling. Ideal for year-round RV use in moderate climates.
• WiFi Control: Allows operation via smartphone app. Useful for pre-cooling or remote adjustments.
• Variable Speed Technology: Eliminates harsh cycling for quieter, more efficient operation.
• Low Ambient Operation: Allows cooling in lower temperatures for dehumidification.
• Programmable Thermostat: Maintains consistent temperatures automatically.
