Buying Guide: What to Look For in an RV Air Conditioner
Choosing the right RV air conditioner goes beyond just the brand. Here are a few key factors to consider:
- BTU Capacity: 13,500 BTUs is standard for most medium to large RVs, but smaller rigs might get away with 11,000 BTUs, while very large or multiple-zone RVs might need 15,000 BTUs or more than one unit.
- Airflow (CFM): Higher CFM means better air circulation and quicker cooling. The 320 CFM offered by these Coleman Mach 3 Plus models is quite good.
- Cool-Only vs. Heat Pump: Decide if you need just cooling or if a unit with a heat strip or heat pump (like the Airxcel 08-0079) would be beneficial for shoulder season camping.
- Amperage Draw: Ensure your RV’s electrical system can handle the AC unit’s amperage, especially if you’re frequently on 30-amp shore power.
- Profile: A low-profile unit can be more aerodynamic and look sleeker, while a medium or high profile might offer more robust components or better airflow.
- Ducting: Decide if you need a ducted or non-ducted system. Most Coleman Mach 3 Plus units can be adapted for both.
FAQs About the Coleman Mach 3 Plus RV Air Conditioner
Q1: What does “Mach 3 Plus” signify in Coleman RV AC units?
A: “Mach 3 Plus” generally indicates a specific series of Coleman-Mach RV air conditioners known for their robust 13,500 BTU cooling capacity and durable construction. It signifies a workhorse unit designed for reliable performance and often features strong airflow.
Q2: What BTU capacity do I need for my RV?
A: For most RVs up to about 30 feet, a 13,500 BTU unit like the Coleman Mach 3 Plus is usually sufficient. Larger RVs (30+ feet) or those with multiple zones might benefit from a 15,000 BTU unit or even two AC units for optimal cooling.
Q3: How does the Coleman Mach 3 Plus compare to other RV AC units?
A: The Coleman Mach 3 Plus is well-regarded for its durability, consistent cooling performance, and relatively strong airflow. It’s often considered a reliable, no-frills workhorse compared to some units that might offer quieter operation or more advanced smart features but at a higher price point.
Q4: Is installing a Coleman Mach 3 Plus difficult for a DIYer?
A: If you’re replacing an existing unit, the installation can be quite straightforward as the mounting holes and electrical connections are often similar. However, working on an RV roof with heavy equipment and high-voltage wiring always carries risks. If you’re unsure, it’s always best to consult a professional RV technician.
Q5: What’s the difference between ducted and non-ducted RV AC systems?
A: A ducted system uses vents and channels built into your RV’s ceiling to distribute cool air more evenly. A non-ducted system blows air directly from the unit’s ceiling assembly, which is simpler but can result in less even cooling. Many Coleman Mach 3 Plus units can be configured for either system depending on the internal ceiling assembly chosen.
Q6: How often should I maintain my RV air conditioner?
A: Regular maintenance is crucial! You should clean or replace your air filter every month or two, depending on usage. Annually, inspect the coils for dirt, check the fan blades, and ensure the shroud is intact. Keeping the condenser coils clean is vital for efficiency.
Q7: Can a Coleman Mach 3 Plus be used with a heat pump?
A: Some Coleman Mach 3 Plus models, like the Airxcel 08-0079 reviewed above, come with an integrated electric heat strip, offering basic heating functionality. While not a true heat pump, it provides supplemental heating. Check the specific model’s features if heating is a priority.
