Welcome to Legacy EV the Valley leader in charger maintenance and services, your one stop shop for all your Electric Vehicle Charging needs. We offer the following services: Level 2 EV Charger Installation Charger Service and Maintenance Electric Panel Upgrades Home wiring and re-wiring needs

"EV Clients Beware – Is the minimal savings worth it in the long haul? I want to share my experience with Legacy EV so other EV owners can avoid the stress, wasted time, and financial headache I’ve endured. What looked like a promising purchase has turned into weeks of frustration, misleading promises, and an outright refusal to take responsibility. The Product Failure I purchased a Tesla Universal Wall Connector from Legacy EV. Almost immediately, the unit began failing intermittently — sometimes charging, sometimes not, with error codes like a blinking blue light appearing randomly. Despite having a licensed, bonded, and insured electrician (the same one who installed it) return multiple times to confirm the installation was correct, the issues continued. This was clearly not an installation problem. The Runaround Legacy EV claimed that help would be “readily available” and that a full refund would be honored if the product was defective. Instead, I’ve been met with endless voicemail prompts, unreturned calls, and English-speaking representatives who are nearly impossible to reach. When I finally did get through, I was told to contact Tesla, who then redirected me to GMC, who — unsurprisingly — refused to help since it’s not a GMC product. Misleading Sales Practices When I asked directly who owned the company, President and Cofounder Mavrick Knoles didn’t disclose his own role — only for me to later find out the truth. This lack of transparency, combined with false assurances about refund and support policies, raises serious ethical concerns. The “Options” They Offered Were Insulting • File a warranty claim with Tesla • Return it with a restocking fee (despite being told a full refund would be honored if defective or was not working properly with a non Telsa EV) • Buy another unit from them (why would I when the first one was a disaster?) The Reality Legacy EV’s business model seems to hinge on dodging responsibility and making customers jump through hoops until they give up. I have detailed documentation, photographs, and time logs of every interaction, and I am now pursuing complaints with the BBB, the Arizona Attorney General’s Office, local news outlets, and preparing for legal action to recover my costs and damages. If you value honesty, timely customer service, and getting what you paid for, do NOT trust Legacy EV. The small initial savings are absolutely not worth the nightmare that may follow. #LegacyEV #EVCharging #ConsumerWarning #BadBusiness #EVOwnersBeware #TeslaChargerFail"

Generator Install questions, answered by experts

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

When properly maintained, natural gas generators can last a long time, as much as 20 to 40 years. They have relatively few needs compared to generators with other fuel types. However, the generator’s lifespan ultimately depends on how often the generator is used and for how long it’s left running.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.
