How to Hire the Best EV Charging Companies: Why Your EV Charger Installer Matters

Electric vehicles (EVs) continue to gain traction across the U.S., with more than 1.5 million new EVs added in 2024 and registrations continuing to rise into 2025—even as federal incentives have shifted and the market has matured.

While year‑over‑year growth has moderated compared to earlier surges, EV adoption remains on a steady upward trajectory as more drivers transition to electric transportation and invest in long‑term charging solutions at home.

As EV ownership expands, selecting a qualified EV charger installer is more important than ever to ensure safety, reliability, and long‑term compatibility as charging technology evolves

Top EV Charging Companies Have Expertise in EV Charger Technologies

With 80% of EV owners charging at home, residential Level 2 EV chargers are quickly emerging as an affordable and convenient option. Many EV charging companies offer installation services, but not all installers can deliver quality service. When choosing your installer, it is important to hire an electrician who is certified in EV charger installations and other electrification services, has comprehensive knowledge on the latest electrification trends and installation techniques, as well as a strong understanding of what charger best meets your everyday needs.

Technology Expertise

Installing a residential Level 2 EV charger is fundamentally different from installing traditional household appliances. Modern EV chargers draw sustained high electrical loads and must comply with National Electrical Code (NEC) requirements for continuous use, proper circuit sizing, grounding, and protection.

Beyond basic wiring, today’s installers must also understand charger power ratings, load calculations, and how charging equipment interacts with a home’s overall electrical capacity.

As charger capabilities increase—often delivering 40 to 80 amps for faster charging—experienced installers are essential to assess whether a home’s electrical panel can safely support the load or if smart load management solutions are required.

Qualified EV charging professionals ensure installations are designed not just for today’s vehicles, but for future EVs with higher‑capacity batteries and charging demands.

Understanding Evolving Charging Standards

The EV charging landscape has evolved significantly in recent years, and installer expertise must evolve with it.

In North America, the industry is transitioning toward the North American Charging Standard (NACS), now adopted by most major automakers, while many existing vehicles continue to rely on CCS connectors. A knowledgeable EV charger installer understands how to future‑proof home charging installations by planning conduit sizing, breaker capacity, and panel headroom that supports changing connector standards without requiring costly rewiring.

Working with an installer who stays current on charging standards helps ensure homeowners are prepared for future vehicle upgrades, adapter‑free charging, and emerging technologies—without compromising safety or performance.

High-Quality Materials

The quality of materials used in an EV charger installation plays a critical role in long‑term performance and safety. Professional installers select wiring, breakers, and protective tubing that meet or exceed NEC requirements for continuous electrical loads, environmental exposure, and heat resistance.

As EV charging increasingly moves outdoors or into garages with fluctuating temperatures, commercial‑grade components help ensure reliability for years to come. A certified EV charger installer also accounts for proper disconnects, grounding methods, and GFCI protections, helping homeowners avoid common installation failures that can lead to tripped breakers, damaged equipment, or electrical hazards.

Latest Trends

From 2023 through 2025, U.S. EV registrations continued to grow, with annual additions surpassing 1.5 million vehicles in 2024 and a 9% year‑over‑year increase in registrations in Q1 2025, even as overall market growth moderated following incentive changes.

As the industry evolves and new charging products are on the market, recommendations from EV charger manufacturers are updated, as well as changes to the national or local codes are modified to better fit the new technology, you will want to be sure that your installer is up-to-date, EVITP certified, as well as continually upskilling their installation knowledge and practices.

Compatibility and Performance

When figuring out what charger is the best fit for your EV and your lifestyle, it’s important to also take into consideration EV battery capacity and EV charger capabilities. Keep in mind that your electric vehicle will not be able to charge beyond the vehicle’s kWh and amperage capacity, so having a higher-powered charger that exceeds this will not be beneficial.

An experienced installer will be able to recommend the right charger for your vehicle by considering how much amperage your EV’s battery can support, whether your vehicle uses the J1772 charging protocol or the newer NACS ports, your existing electrical infrastructure, and daily driving needs.

You can also discuss future-proofing with your installer by exploring technologies like bidirectional charging or selecting a charger with an adjustable amperage to anticipate your next EV purchase.

Compliance With Local Codes and Regulations

Aside from meeting installation requirements outlined in the National Electric Code (NEC) and any EV manufacturer recommendations, specialized electricians working with these technologies should also install chargers in accordance with any local codes and regulations to ensure that the installation is safe, passes inspections, functions at top performance, and is insured for electrical fires with the necessary permits.

Safety

As the National Electric Code is only updated every 3 years and the technology behind EVs and EV charging is evolving at a much more rapid pace, many municipalities have also developed local ordinances designed to further improve safety for at-home EV charging, with rules governing emergency disconnects, location requirements, or load management best practices that are updated to match the improving technology.

While many of these laws and requirements are designed to meet the safety needs for a continual use between 4-10 hours of EV charging each night, they still may not be sufficient based on the latest requirements. As such, it is critical that your EV charger installer is aware of not only these national, state, local, and utility requirements, but also any manufacturer requirements and other best practices.

Failing to follow these rules and industry best practices can result in failing components, melted materials, a lower efficiency on your EV charger, and can even jeopardize the safety of your electrification project resulting in losses that may not be covered by insurance if your EV charger installer is unqualified or not properly certified to perform these installations.

Passing an Inspection

Upgrading your home with an EV charger often means you’ll have to pass an inspection from your local building department. In this event, before you can pass the inspection and use your EV charger, your project will have to comply with any NEC and local code requirements to avoid incurring additional expenses or charging downtime as any issues are resolved.

By hiring a reputable installer, you can ensure your project will comply with any local or national codes and satisfy necessary requirements so you can safely enjoy the convenience of at-home charging for your new EV.

Performance Issues

In addition to ensuring safety, local code will also make sure that your equipment’s performance is enhanced, so it can function to the best of its abilities.

At-home charging is ideal for making the charging experience for EV drivers convenient and cost-effective, but a poor wiring job can result in underperforming equipment and require repairs or upgrades, increasing the upfront cost of charging at home and leaving you without reliable charging.

Insurance and Liability

Once your EV charger is installed, you will need to notify your homeowner’s insurance and they will ensure your installation meets all the NEC and local requirements. It is important that you hire a certified and expert electrician who can confirm these installation requirements are met as a non-compliant installation could void your insurance policy due to an increased risk of electrical fires.

In addition to making sure your project meets national and local requirements, an experienced installer is also able to plan your electrification project to success and file the necessary permits on your behalf, making them liable for ensuring everything is done correctly.

Efficient Installation and Setup

From accessibility issues to outdated wiring, each residential charging installation presents unique challenges. The best way to navigate these obstacles is to work with an experienced professional.

The Benefits of Expert Installation

An experienced installer can recommend a charging equipment option from a trusted manufacturer that meets all your expectations and allows for the fastest charging possible. Following best installation practices results in optimal performance and can significantly reduce future costs associated with potential repairs or maintenance.

Investing in expert installation is worth it. You’ll have the peace of mind that your EV charger is safely installed and will work as expected.

Potential Challenges

Each residential EV charging project is unique.

An experienced installer will assess the existing wiring, determine whether your electrical panel needs an upgrade or replacement to support EV charging and any future electrification projects, or plan for any installation complexities such as trenching, distance, or other challenges based on your home and charging needs. They can also design charging solutions to make your charger more accessible if needed.

Comprehensive Post-Installation Support

Reputable EV charging companies typically offer additional value in the form of maintenance agreements. These plans usually include a periodic check of your charging equipment and all components, seasonal maintenance, and routine care.

Protecting your investment with post-installation support is similar to keeping up with a maintenance schedule for an ICE vehicle. Being proactive prevents downtime and can save you money by preventing avoidable issues that become worse with negligence.

A contractor with a loyal customer base who continues to work with clients after the initial installation is completed is a good sign of a professional and reputable electrician. Ideally, they should offer ongoing maintenance, troubleshooting services, customer support, and a protection plan for their workmanship.

Post-installation support will help you get the most out of your home charging setup and ensure a positive charging experience throughout the lifespan of your at-home EV charger.

Smart Charging, Incentives, and Utility Requirements

In 2026, many utilities now offer EV‑specific rate plans, managed charging programs, and incentives designed to reduce grid impact during peak hours. As a result, EV charger installers must understand how to configure chargers for time‑of‑use rates, smart charging capabilities, and utility program participation.

Incentives and permitting requirements can vary significantly by region, often requiring detailed documentation and code‑compliant installations to qualify. Working with an experienced EV charging company helps homeowners navigate these complexities while ensuring their installation meets local permitting standards and incentive eligibility requirements.
