FAQ Section: Your Questions About RV Air Conditioners Answered
Q1: What BTU cooling capacity do I need for my RV?
A: This largely depends on the size of your RV and the climate you typically travel in. As a general guideline:
* Small RVs (under 20 ft): 8,000 – 10,000 BTUs
* Medium RVs (20-30 ft): 11,000 – 13,500 BTUs
* Large RVs (over 30 ft) or in very hot climates: 15,000 BTUs or more, possibly even two units.
It’s always better to slightly overestimate than underestimate.
Q2: What’s the difference between a ducted and non-ducted RV air conditioner?
A:
* Ducted systems: Distribute cool air through a series of vents in your RV’s ceiling. This provides more even cooling and can be quieter inside since the main unit isn’t blowing directly into the living space.
* Non-ducted systems: Blow air directly from the unit’s return air grill into a single zone of the RV. They are simpler to install and often found in smaller RVs or as secondary units.
Q3: How much power does an RV air conditioner typically draw?
A: Most standard 13,500 BTU RV ACs draw around 12-15 amps on start-up (surge) and 10-12 amps while running. 15,000 BTU units will draw slightly more. This is important for ensuring your shore power connection (30A or 50A) or generator can handle the load, especially if running other appliances simultaneously.
Q4: Can I run my RV air conditioner on a generator?
A: Yes, most RV air conditioners can run on a generator, but you need one with sufficient wattage. A 13,500 BTU unit typically requires a 3,000-watt generator, while a 15,000 BTU unit often needs 3,500-4,000 watts. Always check your AC unit’s specific power requirements.
Q5: How often should I perform maintenance on my RV AC unit?
A: Regular maintenance is key for efficiency and longevity.
* Monthly (during use): Clean or replace air filters.
* Seasonally (before/after season): Inspect the fan blades for debris, clean the condenser and evaporator coils (carefully!), check electrical connections, and ensure the condensate drain is clear.
* Annually: Consider a professional inspection to check refrigerant levels and overall system health.
Q6: What does “low-profile” mean for an RV air conditioner?
A: A low-profile RV AC unit is designed to sit lower on your RV’s roof compared to standard units. This is beneficial for:
* Clearance: Helps you avoid hitting low overhangs, bridges, or tree branches.
* Aerodynamics: Reduces drag and can potentially improve fuel efficiency.
* Aesthetics: Blends more seamlessly with the RV’s roofline.
Q7: Can I replace my RV’s existing AC unit with a different BTU rating?
A: Yes, you generally can, provided the new unit fits the existing 14″ x 14″ roof opening. However, ensure your RV’s wiring and electrical system can handle the amp draw of a higher BTU unit. If downgrading, ensure the lower BTU unit will still effectively cool your space. Always consult your RV’s manual or an RV technician if you’re unsure.
