If you’ve lived through a New England winter, you know how unpredictable and dangerous power outages can be. Between snowstorms, high winds, and ice, towns like Wakefield and Stoneham are no strangers to prolonged outages.
The best way to protect your family and your home is with a whole-house generator. Two top names dominate the market: Generac and Kohler. But which is better for your specific needs?
At Castro Electric Corp, we’ve installed and serviced both. Here’s how they compare and how you can choose the best backup system for your home.
Why You Need a Whole-House Generator
Unlike portable units, a standby generator:
- Starts automatically within seconds of an outage
- Powers your heat, fridge, lights, sump pump, and more
- Runs on natural gas or propane
- Protects your family during freezing temperatures or extended storms
A generator installation is an investment in year-round peace of mind.
Generac Generators: Affordable & Reliable
Generac is the most widely recognized name in residential backup power. Their units are:
- Budget-friendly compared to other premium brands
- Designed specifically for home use
- Backed by remote monitoring features via smartphone apps
- Easy to service — parts are widely available
For smaller or mid-sized homes, Generac often hits the sweet spot between cost and reliability. It’s also a top choice for clients adding an EV charger or upgrading their panel.
Kohler Generators: Built Like a Tank
Kohler’s roots are in industrial-grade engines and commercial power. Their residential generators offer:
- Heavy-duty engine design
- Less frequent valve maintenance
- Rugged enclosures to resist salt air and coastal corrosion
- Quiet, durable performance in extreme conditions
Kohler tends to cost more up front, but many coastal and North Shore homeowners prefer its build quality.
Key Differences:
| Feature | Generac | Kohler |
| Price | More affordable | Premium tier |
| Remote Monitoring | Included | Included |
| Maintenance | Standard | Less frequent |
| Coastal Protection | Good | Excellent |
| Engine Durability | Residential-grade | Industrial-grade |
Installation Matters More Than Brand
No matter which generator you choose, proper installation is critical. At Castro Electric, we manage the entire process:
- Site evaluation and unit sizing
- Permits and code compliance
- Gas line connections
- Concrete or gravel base
- Wiring to your electrical panel
- Final system testing and homeowner walkthrough
We also recommend integrating surge protection to safeguard your electronics during transitions between grid and generator power.
Plan Ahead for Winter Weather
Installing a standby generator isn’t a last-minute job. It involves scheduling, permitting, and preparation — which is why fall is the ideal time to install. Don’t wait until a blizzard hits and leaves your home without power for days.
