Understanding Ducted RV Air Conditioners
Before we jump into the reviews, let’s quickly touch on what “ducted” means. Unlike non-ducted units that blow air directly into a single area, ducted RV air conditioners distribute cool air through a series of vents located throughout your RV. This system provides more consistent temperatures across different zones, often operates more quietly, and can create a cleaner, more integrated look in your RV’s ceiling. Many of the units we’ll review are designed to seamlessly integrate with your existing ducted system or provide the core power for one.

FAQ Section
Q1: What exactly does “ducted RV air conditioner” mean?
A1: A ducted RV air conditioner distributes cool air through a series of vents and channels built into your RV’s ceiling or walls, much like a residential central air system. This provides more even cooling throughout multiple areas of your RV and often results in quieter operation compared to non-ducted units that blow air directly from a central grille.
Q2: How do I know if my RV has a ducted system?
A2: You can typically tell if your RV has a ducted system by looking at the ceiling. If you see multiple small grilles or vents spread throughout the cabin, rather than just one large central grille under the AC unit, you likely have a ducted system. Many modern RVs come equipped with ducted AC.
Q3: What BTU size do I need for my RV?
A3: The appropriate BTU (British Thermal Unit) size depends on your RV’s length, insulation, window area, and the climate you typically travel in. A general guideline is:
– Small RVs (under 20 ft): 10,000 – 13,500 BTU
– Medium RVs (20-30 ft): 13,500 – 15,000 BTU
– Large RVs (over 30 ft): 15,000 BTU or often a dual-zone system with two AC units.
It’s always best to consult your RV’s manufacturer recommendations or a professional.
Q4: What are the main benefits of choosing a Coleman-Mach RV AC unit?
A4: Coleman-Mach has a long-standing reputation for durability, performance, and innovation in the RV industry. Benefits include powerful cooling capacities, reliable construction, a wide range of models (from standard to low-profile and energy-efficient), and widespread availability of parts and service. They’re built to withstand the rigors of RV travel.
Q5: Can I install a Coleman ducted RV air conditioner myself?
A5: Installing an RV air conditioner can be a complex task that typically requires electrical knowledge, roof access, and careful handling of heavy equipment. While some experienced DIYers might attempt it, it’s generally recommended to have a certified RV technician perform the installation to ensure proper sealing, wiring, and functionality, especially for ducted systems.
Q6: What is R-32 refrigerant, and why is it important?
A6: R-32 is a newer generation refrigerant that is becoming increasingly popular due to its higher energy efficiency and lower global warming potential (GWP) compared to older refrigerants like R-410A. Units using R-32 can offer better cooling performance while being more environmentally friendly.
Q7: How often should I clean my RV AC filter?
A7: It’s a good practice to check and clean your RV AC filter frequently, especially during periods of heavy use or if you’re traveling in dusty conditions. Most manufacturers recommend cleaning or replacing the filter at least once a month. A clean filter ensures optimal airflow, efficiency, and air quality.
Q8: What’s the difference between a heat strip and a heat pump in an RV AC unit?
A8: A heat strip is an electric heating element that provides supplemental warmth, similar to a toaster coil. It draws significant electricity and is best for mild heating needs. A heat pump, on the other hand, is a more efficient system that reverses the AC’s cooling cycle to extract heat from the outside air and transfer it inside. Heat pumps are more energy-efficient for heating, especially in moderate temperatures, but their effectiveness decreases in very cold weather.
