FAQ Section
Q1: How do I know what BTU size I need for my RV?
A: The general rule of thumb is 1,000 BTUs per every 50 square feet of living space. However, factors like ceiling height, window area, insulation quality, and the climate you typically travel in also play a big role. For very large RVs (over 30 feet) or those frequently in hot, humid climates, higher BTU units (like the 18,000 BTU models or even aiming for a 20000 BTU rv air conditioner if available) are often recommended.
Q2: Are 20000 BTU RV air conditioners common?
A: Dedicated 20,000 BTU RV air conditioners are not as common as 13,500 BTU or 15,000 BTU units in the standard rooftop format. While some specialized or commercial RVs might feature them, many manufacturers opt for high-capacity units in the 16,000 BTU to 18,000 BTU range, or suggest using multiple smaller units for very large rigs to achieve equivalent cooling power.
Q3: What’s the difference between ducted and non-ducted RV ACs?
A: A ducted RV AC distributes cool air through a system of vents in your RV’s ceiling, offering more even cooling and often quieter operation within the living space as the main unit is hidden. A non-ducted RV AC, on the other hand, blows air directly from the rooftop unit into the living area via an air distribution box, typically providing faster, more direct cooling to a single zone.
Q4: How important is a low amp draw for RV ACs?
A: Extremely important, especially for boondockers or those relying on generators or solar power. A lower amp draw means your AC consumes less electricity, allowing you to run other appliances simultaneously, extend battery life, or use smaller generators. This is a key factor when considering any high-capacity unit.
Q5: Can I install an RV AC myself?
A: While some RV AC units are designed for relatively straightforward “bolt-on” installation, it’s generally recommended to have a professional install it, especially if you’re not experienced with electrical wiring, sealing, or rooftop work. Improper installation can lead to leaks, electrical problems, or inefficiency.
Q6: What are variable speed compressors?
A: Traditional RV ACs have single-speed compressors that are either fully “on” or “off.” Variable speed compressors can adjust their speed based on the cooling demand. This allows them to run almost continuously at lower speeds, maintaining a more consistent temperature, using less energy, and significantly reducing the noisy on/off cycling of the unit.
Q7: How do I maintain my RV air conditioner?
A: Regular maintenance is key for longevity and efficiency. This includes cleaning or replacing air filters, checking the condenser and evaporator coils for debris, inspecting the roof gasket for leaks, and ensuring all electrical connections are secure. Always refer to your unit’s owner’s manual for specific maintenance guidelines.
