St. Louis summer heat is ramping up — and your air conditioner is one of the biggest electrical loads in your home.

That matters when you’re shopping for a standby generator.

Some companies solve that problem by simply selling you a bigger generator.

But bigger isn’t always smarter.

At Generator Supercenter of St. Louis, our Power Solutions Consultants design systems with smart load management, helping your generator prioritize what matters most — AC comfort, refrigerators, freezers, WiFi, sump pumps, medical devices, and everyday essentials — without paying for more generator than you actually need.

This June, get:

✅ $1,000 off new Generac standby generator installations
✅ 2 free load managers included
✅ Free 7-year extended warranty from Generac when you sign an install agreement by June 12th
✅ Turnkey installation, local service, maintenance & monitoring

Stay cool. Stay protected. Get a system designed the right way from the start.
