Easy Start Breeze RV AC Soft Starter for RV Air Conditioners

Replaces 399-X20

1 Year Warranty

The Micro‑Air EasyStart Breeze 399‑X20BL is the newest Bluetooth‑enabled RV AC soft‑starter engineered to reduce compressor inrush current by up to 75%. This allows RV owners to run their rooftop or basement air conditioner on smaller inverter generators, limited shore power, or solar + battery setups without tripping breakers or dimming lights.

Designed for 120V RV air conditioners up to 18,000 BTU, the EasyStart Breeze provides smooth compressor startup, quieter operation, and improved reliability in hot‑weather conditions. The onboard Bluetooth module lets technicians and RV owners monitor performance and startup profiles directly from the Micro‑Air app.

Each kit includes the full installation harness, mounting hardware, and step‑by‑step instructions—making it ideal for DIY installs or professional RV service centers.

Why Every Pet‑Owner Should Have an EasyStart Breeze in Their RV

The Micro‑Air EasyStart Breeze 399‑X20BL isn’t just an upgrade for your RV air conditioner — it’s a critical safety tool if you travel with pets. RV A/C units pull a huge surge of power when they start, and that surge is what trips breakers, overloads small generators, or causes your A/C to fail during the hottest part of the day.

With the EasyStart Breeze reducing startup current by up to 75%, your A/C starts smoothly and reliably, even on:

• Small inverter generators

• Limited campground shore power

• Solar + battery setups

• Older or inconsistent RV park electrical systems

That reliability directly protects your pets. If you leave your animals inside the RV while you run errands, hike, or explore, you need absolute confidence that your A/C will stay running — not shut off because of a power hiccup.

How It Helps You Monitor & Protect Your Pets

• Stable A/C operation = stable interior temperature No sudden shutdowns that could put your pets at risk in extreme heat.

• Works with remote monitoring systems If you use RV pet‑monitoring apps or temperature sensors, the EasyStart Breeze keeps your A/C running so your alerts stay accurate.

• Prevents breaker trips during peak heat When everyone in the campground is pulling power, your A/C still starts smoothly.

• Peace of mind when you’re away from the RV You don’t have to worry about your generator failing to restart the A/C.

Bottom Line

If your pets depend on your RV’s air conditioner to stay safe, the EasyStart Breeze is one of the most important upgrades you can install. It keeps your cooling system reliable, even in the toughest electrical conditions — giving you confidence every time you step away from your RV.
