Electrical Services You Can Trust from A+ Derr Heating, Cooling, Plumbing, & Electrical

Electrical Installation

Electricity is the silent force powering nearly every corner of your home or business. It lights your rooms, runs your appliances, and keeps your family connected and comfortable. But when something goes wrong, or your system can’t keep up with modern demand, it’s more than just an inconvenience. That’s where A+ Derr comes in.

Electrical Repair: Fast, Safe, and Done Right

Are you dealing with flickering lights, faulty outlets, or frequent circuit breaker trips? Don’t ignore the signs. These small issues can quickly turn into larger problems if left unaddressed. Our team is equipped with the tools and knowledge to diagnose and repair electrical issues safely and efficiently.

We treat every job—big or small—with the same level of professionalism. We take time to explain the issue, walk you through your options, and get everything working safely again. If something doesn’t seem right with your home’s electricity, it’s always better to be safe than sorry.

Professional Electrical Installation

Whether you’re remodeling a kitchen, building a new addition, or upgrading your home’s wiring, our electrical installation services ensure everything is done to code and designed for long-term performance. We install:

You’ll never feel left in the dark—our electricians take time to answer your questions and design an electrical system that fits your home and lifestyle perfectly.

Reliable Generator Installation

Let’s face it—losing power throws everything into chaos. The food in your fridge starts warming up, your phone dies, and suddenly you’re trying to navigate your house with a flashlight in one hand. At A+ Derr Heating, Cooling, Plumbing, & Electrical, we believe you shouldn’t have to hit pause on life just because the grid went down.

That’s why we offer turnkey generator solutions that keep your home humming. Our standby generators kick on automatically during an outage, keeping essentials like your fridge, HVAC, and devices running without missing a beat.

Panel & Meter Base Upgrades

Is your home’s electrical panel outdated or struggling to keep up with your power demands? We can upgrade your electrical panel and meter base to support modern living. This is essential if you’re:

  • Adding large appliances
  • Installing an EV charger
  • Planning a home renovation
  • Experiencing frequent breaker trips

Upgrading your panel isn’t just about performance—it’s about protecting your home from dangerous overloads and potential fire hazards.

Circuits & Outlets

Adding more outlets or dedicated circuits can dramatically improve how your home functions. Whether it’s for a new home office, a media center, or a kitchen appliance, we can install or relocate outlets exactly where you need them. We’ll also ensure that high-demand devices are on their own circuits to avoid overloading your system.

If you have outdated two-prong outlets or notice your plugs are loose and falling out, give us a call—we’ll bring your home up to today’s safety standards.

Service Upgrades for Modern Living

As our homes become more tech-heavy—with devices, appliances, and electric vehicles—many older electrical systems simply can’t keep up. If your home was built decades ago and hasn’t had an electrical service upgrade, you could be at risk for electrical failures, inefficiency, or even fire hazards.

We’ll evaluate your current electrical system, discuss your energy needs, and provide a full-service upgrade that keeps your home ready for the future.

Whole-Home Surge Protection

Think of whole-home surge protection like an invisible security system for everything plugged into your walls. One unexpected jolt—from a lightning strike, a utility malfunction, or even your own appliances cycling on and off—can fry your electronics in a flash. TVs, computers, kitchen gadgets, HVAC systems—none of them are immune.

That’s why we recommend surge protection that doesn’t rely on power strips or guesswork. Our systems are wired directly into your electrical panel to shield your entire home from sudden voltage spikes. It’s a one-time investment that quietly works in the background, giving you peace of mind every time you flip a switch or plug something in.

Custom Lighting Solutions

The right lighting adds warmth, functionality, and safety to any space. We offer custom lighting design and installation services for:

  • Recessed and track lighting
  • Pendant and accent lighting
  • Outdoor security lights
  • Landscape lighting
  • Motion-activated lighting

We’ll help you create a lighting layout that enhances the beauty of your home while improving energy efficiency and safety.

EV Charger Installation

Thinking about switching to an electric vehicle—or already made the leap? A home EV charger makes daily life easier and more convenient. We install Level 2 EV charging stations compatible with all major brands, ensuring your vehicle charges faster and more reliably than with standard outlets.

We’ll assess your panel’s capacity, recommend the best charger, and make sure everything is installed safely and correctly.

Equipment Repair

When equipment breaks down, you need it fixed fast. We offer dependable repair services for a range of electrical components, including:

  • Light fixtures
  • Breakers and panels
  • Generators
  • Switches and dimmers

We focus on long-term solutions—not just patchwork fixes. You can trust us to diagnose the issue correctly and repair it with care.

Light Commercial Electrical Services

If you own or manage a small business, you understand how critical electrical systems are to daily operations. We specialize in light commercial electrical work for offices, boutiques, restaurants, and small retail locations.

From system upgrades and safety inspections to new wiring and lighting, we help keep your business running without interruption.
