Buying Guide: Key Purchase Considerations
Power compatibility: Check your RV’s electrical system—whether 15A, 20A, or 30A—and confirm the soft start’s rated startup current reduction. This determines if you can run the A/C and other appliances simultaneously.
BTU and capacity: Match the unit’s cooling capacity with your A/C model. Some kits advertise support for up to 36,000 BTUs across multiple units, while others focus on single 15,000 BTU systems.
Waterproof and rugged design: For outdoor exposure and travel, waterproof housings and corrosion resistance extend product life in RV environments.
Ease of installation: Plug-and-play or installation kits with hardware influence installation time and complexity. DIY-friendly options are highlighted for quicker setups.
Generator and power sources: Consider compatibility with portable generators (like 2200W) and park power. Thinking about future trips with different power sources helps in choosing a flexible option.
Noise and comfort: Reduced compressor noise improves overall RV comfort. Start-up smoothness minimizes vibrations and interior disturbances during cool-down cycles.
Safety features: Look for over-voltage, over-current, and short-circuit protection, as well as safeguards against overloading the generator or tripping breakers.
