Run Your AC on a Generator — Without Overloading It
AC soft start kits cut your air conditioner's startup amperage by up to 70%, letting your generator handle the load reliably — even on the hottest Houston days.

Your AC Is the Biggest Threat to Your Generator
When your air conditioner starts up, the compressor draws a massive surge of electricity — often 3 to 5 times its normal running load. That startup spike can trip your generator's breaker, cause voltage sag that damages electronics, or shorten the life of both your generator and your AC compressor. In Houston's summer heat, losing your AC during a power outage isn't just uncomfortable — it's dangerous.
Houston summers are no joke. With heat indexes regularly above 105°F, losing your AC during a power outage is a health risk — not just an inconvenience. A soft start kit ensures your generator can handle the load when it matters most.

What a Soft Start Kit Does
A soft start kit is a small electronic device installed directly on your AC compressor. Instead of letting the motor slam on at full power, it gradually ramps up the compressor — smoothing out the startup surge and dramatically reducing the initial amp draw. The result: your generator handles the load without straining, your AC runs reliably, and both systems last longer.
Protects Your Generator
Eliminates the startup spike that trips breakers and causes voltage sag on undersized generators.
Extends AC Compressor Life
Reduces mechanical stress on the compressor motor, extending its lifespan and reducing repair costs.
Runs Smaller Generators
A 10kW generator that couldn't handle your AC can often run it reliably after a soft start kit is installed.
Works with Existing Equipment
Compatible with most central AC units and heat pumps. No need to replace your AC or upgrade your generator.
Quick Installation
Most soft start kit installations are completed in under two hours — often same day you call.
Year-Round Protection
Benefits extend beyond generator use — soft starts reduce wear on your AC compressor every time it cycles.
Run Your AC on a Portable Generator
Most portable generators can't handle the startup surge of a central AC unit — the compressor draws 3 to 5 times its normal running amps the moment it kicks on, tripping the breaker instantly. A soft start kit fixes that. By cutting startup amps by up to 70%, your portable generator can actually run your air conditioner — keeping your home livable during any outage, not just when a standby unit is installed.
