Electrical panel upgrades
Modern homes pull more power than ever. Tenz Electric sizes, installs and labels panels built for the next thirty years, for homeowners in Asheville, Hendersonville and surrounding communities.
What we handle
Your panel is the heart of your home's electrical system. We start with what your home actually needs today and what you're planning next, then recommend the right-sized solution — not the biggest one.
When an older panel can't keep up with today's appliances, heating and cooling, or a new addition, we size the new service to your home, install it cleanly and label every circuit so you know exactly what's what.
Smart load centers let you see and manage how your home uses power. We'll tell you straight whether one makes sense for your home or whether a standard panel is the better value.
Adding a garage, workshop, addition or finished basement? A sub-panel puts circuits where you need them without overcrowding your main panel.
A surge protector installed at the panel helps protect the electronics and appliances throughout your home from damaging voltage spikes. It can go in during a panel upgrade or as its own job.
Planning an EV charger, heat pump, hot tub or addition? A load calculation shows whether your current panel can handle it, so you only upgrade when you actually need to.

Questions
Still unsure? Call our Arden office and we'll walk you through it in plain English.
Frequent tripping, no open spaces for new circuits, dimming lights when appliances start, or a panel that's warm, buzzing or corroded are the common signs. Planning a big new load, like an EV charger or addition, is another reason to have it checked.
A smart panel or smart load center lets you monitor and manage how power is used in your home, often from an app. It isn't the right fit for every home, and we'll tell you honestly whether it's worth it for yours.
Not always. A load calculation shows whether your existing panel has room. If it does, we add a dedicated circuit; if it doesn't, we'll explain the options, including a panel upgrade.
Yes. Surge protection can be added at the panel during an upgrade or as a separate job.
Yes. Flexible monthly payment options are available for panel and service upgrades. Financing is provided by third-party lending partners and is subject to credit approval.
