Factors to Consider When Buying an RV Coleman Mach Air Conditioner
Choosing the right RV Coleman Mach air conditioner means thinking about a few key things:
- BTU Capacity: This is crucial. Smaller RVs (under 20 ft) might do fine with 10,000-11,000 BTUs, while medium (20-30 ft) usually needs 13,500 BTUs, and larger or hotter climates demand 15,000 BTUs or more.
- Ducted vs. Non-Ducted: Does your RV have ceiling ducts to distribute air, or do you need a unit that blows air directly from the ceiling assembly?
- Profile: Low-profile units (like the Mach 8 Plus) are great for reducing overall height, which can be important for clearance.
- Features: Do you need a heat pump for cold weather? How important is energy efficiency? Do you prefer manual or digital controls?
- Noise Level: While most modern RV ACs are designed to be quieter, some models are specifically engineered for extra quiet operation.
Installation & Maintenance Tips
Getting your new RV Coleman Mach air conditioner up and running, and keeping it that way, is simpler than you might think.
- Professional Installation Recommended: While some DIYers tackle it, a professional installation ensures proper sealing, wiring, and functionality.
- Regular Cleaning: Keep the air filters clean. This is perhaps the easiest and most impactful maintenance task, ensuring optimal airflow and efficiency.
- Check Coils: Periodically inspect the condenser and evaporator coils for dirt and debris. Gently clean them with a soft brush or coil cleaner.
- Monitor Performance: Pay attention to how well your unit is cooling. Any significant drop in performance could indicate an issue that needs attention.

FAQ Section
Q1: How often should I service my RV Coleman Mach air conditioner?
A1: Generally, it’s recommended to have your RV AC unit professionally serviced at least once a year, preferably before the peak cooling season. However, you should clean the air filters monthly or after every few trips, and visually inspect the coils and shroud regularly for debris.
Q2: What’s the difference between ducted and non-ducted RV AC units?
A2: A ducted system distributes cool air through vents located in the ceiling or walls of your RV, offering more even cooling. A non-ducted system blows cool air directly from the unit’s ceiling assembly, often found in smaller RVs or as a primary unit in a single-zone setup.
Q3: What do BTU ratings mean for RV air conditioners?
A3: BTU stands for British Thermal Unit, and it’s a measure of cooling power. Higher BTU numbers indicate a greater ability to cool a larger space or cool a space more quickly. For RVs, 13,500 BTU is common for mid-sized units, while 15,000 BTU is ideal for larger RVs or very hot climates.
Q4: Can I install a Coleman Mach RV AC myself?
A4: While it’s technically possible for experienced DIYers, professional installation is strongly recommended. Proper sealing is critical to prevent leaks, and correct electrical wiring is essential for safety and optimal performance. Many warranties also require professional installation.
Q5: How much power does an RV Coleman Mach air conditioner use?
A5: Power consumption varies by BTU capacity and model. A 13,500 BTU unit typically draws around 12-15 amps on high cool, while a 15,000 BTU unit might draw 14-17 amps. This is important for ensuring your RV’s electrical system (shore power or generator) can handle the load.
Q6: What is R-32 refrigerant, and why is it used?
A6: R-32 is a newer generation refrigerant known for its higher energy efficiency and lower environmental impact compared to older refrigerants like R-410A. It requires less volume to achieve the same cooling capacity, making units using R-32 more efficient and eco-friendly.
Q7: How do I size an RV AC unit for my RV?
A7: Sizing depends on your RV’s length, insulation, number of slide-outs, and typical climate. As a general guide:
– Under 20 ft: 10,000 – 11,000 BTU
– 20-30 ft: 13,500 BTU
– Over 30 ft or in hot climates: 15,000 BTU (or even two units)
It’s always best to consult your RV manufacturer’s recommendations or an RV professional.
Q8: What’s the “Plus” in Mach 3 Plus or Mach 15 Plus mean?
A8: In Coleman Mach terminology, “Plus” often indicates an enhancement over a standard model, which could include improved features like a more robust fan motor, higher airflow (CFM), or a more durable construction. It typically signifies an upgrade in performance or reliability.
