Complete Buying Guide for Best Coleman Rv Air Conditioner
Essential Factors We Consider
Choosing the right Coleman RV air conditioner is more than just picking the biggest unit. First, match the BTU rating to your RV size. A 13,500 BTU unit is perfect for most trailers and motorhomes up to 30 feet, while 15,000 BTU models are for larger rigs. Next, consider your electrical system. A 13.5k BTU unit is more manageable on a 30-amp service than a 15k unit, especially if you add a soft start kit. Finally, think about features: Do you need heat? A model with a built-in heat strip or heat pump adds year-round usability. The physical profile (low, medium, or standard) can affect fuel efficiency and looks.
Budget Planning
Your budget should include more than just the unit cost. Factor in potential shipping for these large items, any necessary accessories (like a new interior air box or a soft start kit), and tools for DIY installation. If you’re not comfortable on the roof or working with electricity, budget for professional installation. Remember, a well-chosen Coleman roof air conditioner is a long-term investment in comfort that can last for many camping seasons.
Final Thoughts
The best choice ultimately depends on your specific rig, travel habits, and power setup. Our top pick, the Coleman 48204C869, offers the best all-around performance for most users. But whether you need maximum power, modern design, or a simple repair part, Coleman’s extensive lineup has a reliable solution. Measure your roof opening, check your breaker panel, and you’ll be ready to make a cool decision.
Frequently Asked Questions
Q: What size Coleman RV air conditioner do I need?
A: A good rule of thumb is 13,500 BTUs for RVs up to 30 feet and 15,000 BTUs for anything larger or for camping in very hot climates. Always check your RV’s existing unit or roof opening compatibility first.
Q: Can I install a Coleman RV AC myself?
A: Yes, if you are comfortable working on your roof and with basic electrical connections. A direct replacement of a same-model unit is often “plug and play.” Adding a second AC or changing models is more complex and may require professional help.
Q: What is a soft start kit, and do I need one?
A: A soft start kit (like #9 on our list) reduces the initial power spike when the AC compressor starts. You need one if you have a 30-amp RV, use a smaller generator, or frequently trip breakers at campgrounds when the AC kicks on.
Q: What’s the difference between a heat strip and a heat pump?
A: A heat strip is like a giant hair dryer—it uses a lot of power to create heat. A heat pump is more efficient, moving heat from outside to inside, but it only works effectively when outside temperatures are above freezing (around 40°F+).
Q: How long does a Coleman RV air conditioner typically last?
A: With proper maintenance, a quality Coleman air conditioner for RV can last 10-15 years. Regular cleaning of the filters and roof coils is the simplest way to extend its life.
