Run your home air conditioner or heat pump on limited power – generators, inverters, or solar – with Micro-Air’s EasyStart™ Flex, the most advanced residential AC soft starter available.

The EasyStart™ Flex Home Soft Starter is a one-size-fits-all solution for all residential AC units up to 6 tons (72,000 BTUs).

Perfect for homes with backup generators, inverters, or solar power systems, the EasyStart™ Flex allows you to run your AC when you need it most – during power outages, off-grid living, or limited utility power situations.
