FUTURE-PROOF YOUR HOME
Adding high-power appliances is exciting, but your electrical panel must be ready for the job. Here's how to know if you need an upgrade.
In Las Vegas, a powerful air conditioner isn't a luxury—it's a necessity. And with the rise of electric vehicles, many homeowners are looking to add fast, convenient Level 2 charging at home. Both of these modern conveniences have one thing in common: they are high-demand electrical appliances that can easily overwhelm an older, undersized electrical panel.
Modern central air conditioners, especially the powerful units needed for a Las Vegas summer, require a large, dedicated 240-volt circuit. While they are more "efficient," they still represent a significant and sustained electrical load on your system.
To get a meaningful charge overnight, a Level 2 (240-volt) charger is essential. This is the equivalent of adding another electric stove or dryer to your home, and it absolutely requires its own dedicated circuit.
The ability of your panel to handle these additions isn't just about having empty breaker slots. It's about the total electrical load calculation. A licensed electrician performs this calculation to determine the total power your home might draw at one time. It accounts for your home's square footage, existing appliances (stove, dryer, water heater), and the new items you want to add.
Most older homes with 100-amp or 150-amp panels are already near their maximum safe capacity. Adding a 50-amp EV charger circuit to a 100-amp panel is often unsafe and against electrical code.
For most homeowners looking to add an EV charger or a new AC unit, the safest and most effective solution is a full electrical panel upgrade to 200 amps. This provides the necessary capacity to power your new appliances safely without overloading your system.
