The brutal summers here (regularly hitting 100°F+) mean your AC is working overtime June through August, and the startup surge from a high-efficiency unit requires solid electrical infrastructure to avoid voltage sags that damage compressors and reduce system lifespan. Upgrading from an older 100-amp to a modern 200-amp panel ensures your cooling system, water heater, and backup power sources run without competing for electricity.

Cedar Park's older subdivisions near Highway 183 often have panels that were never sized for the heat-load realities of central Texas—you'll typically see 60-100 amp services that can't handle a quality HVAC replacement alongside existing home loads. Pool pumps, outdoor kitchens, and landscape lighting are increasingly common in our area, and undersized panels force homeowners to choose between comfort and functionality rather than having both safely.

Before upgrading, request a load calculation from a licensed electrician—don't let anyone sell you more capacity than you need, but also don't cheap out and end up constrained in five years. Many homes benefit from a 150-amp upgrade instead of jumping to 200-amp, which costs less while still covering most realistic loads in a Cedar Park home for the next decade.

The panel upgrade job itself is quickest in spring or fall, but if your AC is struggling or you're adding one before summer, early May is your deadline—waiting until June means electricians are fully booked and temps are already punishing your system. Emergency service is available year-round if a panel failure leaves you without power during peak heat.
