Choosing 100A vs. 200A Upgrades in Sunnyvale
Compare the two paths most buyers and property owners weigh before moving forward locally.
100A (Standard/Legacy)
Usually the better fit when you want a simpler path, tighter short-term cost control, or fewer moving parts during the decision process.
200A (Modern Tech-Ready)
Usually the better fit when long-term performance, durability, or a stronger upside matters more than the lowest upfront number.
Detailed Breakdown
100A is often undersized for Sunnyvale homes with modern electronics. 200A provides the headroom for EV charging, mini-splits, and smart appliances in Downtown / Heritage District.
Use that tradeoff to compare how each option affects timing, long-term upkeep, and how well the work matches the property and market conditions around you.
