Reliable Whole Home Generator Solutions in McKinney, TX
When the grid fails, your life shouldn't have to stop. Top Flow Plumbing Co. specializes in seamless whole-home-generator systems that automatically power your entire property—A/C, appliances, and lights—within seconds of an outage.
Why Settle For Partial Power?
No Climate Control
Small portable units can't run your central A/C or furnace. A whole home system keeps you cool in summer and warm in winter.
Manual Setup
Dragging a portable generator out in the rain and hunting for gas cans is dangerous and exhausting. You deserve automatic protection.
Pick & Choose
Without a whole-home-generator, you have to unplug the fridge to use the microwave. Stop juggling cords and power everything at once.
The Grid Goes Down. You Stay On.
A whole-home-generator is a permanently installed appliance, much like your central A/C unit. It runs on your home's existing natural gas or liquid propane supply, meaning you never have to refuel it. It monitors the utility power 24/7. The moment it detects a blackout, it turns on and transfers power to your home automatically. If you want true peace of mind for your family, get started with a free sizing consultation today.
