Electrical Repair & Troubleshooting in Sandwich, Massachusetts

When the power flickers or an outlet starts buzzing, it’s not something to ignore. In a coastal environment, moisture and salt air seep into electrical systems over time, quietly damaging circuits and creating hazards that aren’t always visible until something goes wrong.

We specialize in finding those hidden problems before they become emergencies. Because we know that losing power isn’t just an inconvenience — it shuts down your AC, ruins your groceries, and leaves your family without light or heat when they need it most.

When something feels off, don’t wait. We’re here to make sure your home stays safe.

Keep an eye out for these critical red flags in your home:

• Flickering Overhead Lights: This often suggests a loose neutral wire or a failing connection in your main panel.
• Hot-to-the-Touch Switches: If a wall plate feels warm, it may indicate an electrical arc or a severely overloaded circuit.
• Discolored Wall Outlets: Charred or brown marks on an outlet indicate that the wiring is overheating and poses an immediate fire risk.
• Constant Circuit Breaker Trips: If you can’t run your AC and your microwave at the same time, your system is crying out for professional troubleshooting.

As a family-owned and operated business, Cotti-Johnson HVAC, Inc. provides honest pricing and rapid response times for every call. We believe in transparent communication, explaining exactly what is happening behind your walls so you can make safe, informed decisions. With customer satisfaction guaranteed, we ensure your Sandwich, Massachusetts, property remains a haven.

Whole Home Generator Repair & Replacement Services in Cape Cod

On Cape Cod, the weather can change fast and when a nor’easter rolls through, power outages can last for days. A whole-home standby generator means you never have to worry about it. The lights stay on, your sump pump keeps running, your food stays cold, and your heating or cooling system never skips a beat.

It’s not just about comfort. Keeping your sump pump and climate systems running during an outage can protect your home from water damage and mold problems that are far more costly than the generator itself. When the power goes out for your neighbors, you’ll barely notice.

Investing in a professional backup power solution provides several unique advantages:

• Seamless Automatic Power: The system detects a blackout and restores power to your home in seconds, even if you are away.
• Permanent Fuel Supply: Most standby units run on your existing natural gas or propane line, eliminating the need for gasoline.
• Protection for Sensitive Tech: Modern whole-home generator systems provide clean power that won’t fry your computers or smart TVs.
• Reliability in All Seasons: From summer hurricanes to winter blizzards, your home remains a safe sanctuary.

Whether you need a new standby generator installation or a fuse box replacement to modernize your home’s connectivity, our electrical contractor team is ready to assist. With our over 75 Years In Business, we understand the specific challenges of the Cape Cod environment. We offer honest pricing and a guarantee of customer satisfaction, ensuring your backup power system is always ready when you need it most.
