Buying Guide: Key Considerations for Choosing Air Conditioner Soft Start Kits
Compatibility With Air Conditioner Size and Type
Check the capacity rating of your AC unit (measured in tons or BTU) before choosing a soft start kit. Kits like the MICRO-AIR EasyStart FLEX 398 support systems up to 6 tons or 72,000 BTU, suitable for residential and commercial use. For RV applications, models like SoftStartRV and SpartanStart fit specific BTU ranges, so confirm compatibility to ensure effectiveness.
Power Source Compatibility
If you plan to use your AC with generators or inverters, select a soft start kit designed to reduce startup current. Kits compatible with generators help prevent overload and allow smoother startup on limited power, reducing the risk of breaker trips. Bluetooth-enabled systems (e.g., MICRO-AIR FLEX) also offer added control and diagnostics.
Installation Ease and Included Accessories
Installation complexity varies among kits. Some come with comprehensive installation kits and DIY-friendly instructions, while others may require professional help. Consider units with included wiring connectors, mounting tape, and clear installation instructions to simplify setup.
Noise Reduction and Operating Smoothness
Soft start kits reduce compressor noise and mechanical vibrations during start-up, improving comfort in homes and RVs. If noise is a priority, select a model with proven quieter operation such as the SoftStartRV or MICRO-AIR Breeze 399.
Durability and Environmental Resistance
For RV or outdoor use, waterproof and rugged designs are important to withstand harsh conditions. Waterproof models like SoftStartRV help ensure longevity and performance in variable environments.
