Tired of your RV’s air conditioner roaring to life, tripping circuit breakers, or demanding a huge, noisy generator just to get a blast of cool air? You’re not alone! Many RVers face the frustrating challenge of limited power while trying to stay comfortable on the road. The solution? A soft start RV air conditioner kit. These clever devices are game-changers, allowing your AC unit to power up smoothly, quietly, and with significantly less electrical demand.
A soft start for your RV’s air conditioner drastically reduces the sudden “inrush current” that typically occurs when the compressor kicks on. This means you can often run your 15,000 BTU AC on a smaller generator (like a 2200W portable unit), a standard 20A household outlet, or even simultaneously with other appliances on a 30A RV hookup. It also reduces wear and tear on your AC unit, extends its lifespan, and provides a much quieter startup, making for more peaceful travels.
In this guide, we’ll dive into the top 10 soft start RV air conditioner kits on the market, helping you find the perfect match to keep your adventures cool and hassle-free.
What is a Soft Start RV Air Conditioner and Why Do You Need One?
At its core, a soft start device is an electronic module that intelligently manages the initial power surge to your air conditioner’s compressor. Instead of the compressor drawing a massive amount of current all at once (known as inrush current), the soft start gradually ramps up the power, reducing the peak draw by up to 75%.
Why is this a big deal for RVers?
- Run AC on Smaller Generators: No more lugging around massive, expensive generators! A soft start can enable you to run a powerful RV AC with a 2200W portable generator, freeing up power for other essentials.
- Avoid Tripped Breakers: Say goodbye to frustrating circuit breaker trips when you fire up your AC, whether you’re hooked up at a campground or on a residential outlet.
- Quieter Operation: The gradual ramp-up significantly reduces the jarring “thump” and noise associated with AC startup, ensuring a more peaceful environment inside your RV.
- Protect Your Equipment: By reducing electrical stress, a soft start extends the life of your AC compressor, generator, and even your RV’s entire electrical system.
- Increased Versatility: Run your AC alongside your microwave, coffee maker, fridge, and other appliances without overloading your power source.
It’s an essential upgrade for anyone looking to maximize their RV’s comfort and power efficiency.

Buyer’s Guide: What to Look for in an RV AC Soft Start Kit
Choosing the right soft start RV air conditioner kit can significantly impact your RV experience. Here’s what to consider before making your purchase:
- AC BTU Rating & Generator Size: Ensure the soft start unit is compatible with your RV’s AC BTU rating (e.g., 13,500 BTU, 15,000 BTU) and that it explicitly states it can work with your intended generator size (e.g., 2200W, 3000W).
- Installation Difficulty: Some kits are designed for “plug-and-play” with color-coded wires, while others might require a bit more technical know-how to identify specific compressor wires. Look for comprehensive instructions, video tutorials, or live support if you’re a DIY beginner.
- Noise Reduction: A key benefit of a soft start is a quieter startup. Check reviews and product descriptions for claims about significant noise and vibration reduction.
- Durability and Protection: RV life can be tough on electronics. Look for features like waterproof casings, dustproof designs, and built-in overload/short circuit protection to ensure longevity and safety.
- Compatibility: While most soft starts are universal, some might have specific compatibility notes for certain AC brands (Dometic, Coleman, etc.) or unit types (low-profile). Double-check before buying.
- Warranty and Support: A good warranty and responsive customer support can be invaluable if you encounter issues during installation or operation.
- Additional Features: Do you need Bluetooth connectivity for monitoring, or intelligent fault detection? Consider if these advanced features are worth a potentially higher price point.
- Size: If you have a low-profile AC unit or limited space, a more compact soft start kit might be a better fit.
FAQ Section
Q1: What exactly does a soft start RV air conditioner do?
A1: A soft start RV air conditioner kit is an electronic device that reduces the initial surge of electrical current (known as “inrush current”) when your AC compressor starts. Instead of a sudden, high power draw, it allows the AC to ramp up smoothly, making it easier to power with smaller generators, limited shore power, or simultaneously with other appliances.
Q2: Do I really need a soft start for my RV air conditioner?
A2: If you frequently experience tripped circuit breakers when starting your AC, want to run your AC on a smaller portable generator (like a 2200W unit), wish to use your AC on a 15A or 20A household outlet, or simply desire quieter AC startups and extended equipment life, then yes, a soft start is a highly beneficial upgrade.
Q3: Can I install a soft start kit myself, or do I need a professional?
A3: Many soft start kits are designed for DIY installation, especially those with color-coded wires and detailed instructions or video tutorials. However, installing one does involve working with your RV’s electrical system and the AC unit, so basic electrical knowledge is helpful. If you’re unsure, consulting a professional RV technician is always recommended.
Q4: Will a soft start allow me to run two RV air conditioners on a 30-amp service?
A4: Yes, in many cases! Installing a soft start on each of your RV AC units can significantly reduce their combined startup current, often allowing you to run both on a 30-amp hookup. Always check the specific product’s capabilities and your AC units’ combined running wattage.
Q5: Does a soft start save energy or reduce power consumption?
A5: While a soft start doesn’t reduce the overall energy consumed by your AC over time, it drastically lowers the peak power draw during startup. This means you can use smaller power sources and avoid overloading your system, but it won’t necessarily lower your monthly electricity bill.
Q6: How long does it take to install an RV AC soft start kit?
A6: Installation times vary depending on the specific product and your experience level. Many manufacturers claim installation can be done in 15-60 minutes for DIYers with some kits being “plug-and-play.” However, it’s wise to set aside a couple of hours and thoroughly review the instructions beforehand.
Q7: Will a soft start extend the life of my RV air conditioner?
A7: Yes! By reducing the harsh inrush current and the associated mechanical stress on the compressor and other electrical components, a soft start helps protect your AC unit from premature wear and tear, effectively extending its lifespan.
Q8: Are soft start kits compatible with all RV air conditioner brands?
A8: Most soft start kits are designed to be widely compatible with common RV AC brands like Dometic, Coleman, and Advent. However, it’s always best to check the product’s compatibility list or contact the manufacturer if you have a less common or older AC unit to ensure a proper fit.
Conclusion
Upgrading your RV with a soft start RV air conditioner kit is one of the smartest investments you can make for enhanced comfort and peace of mind on the road. These ingenious devices tackle common RV power headaches head-on, allowing you to enjoy cool air on smaller generators, prevent frustrating breaker trips, and extend the life of your valuable equipment.
