How we vet Electrical Panel Upgrade pros in Surprise

Our 5-step screening for Electrical Panel Upgrade contractors serving Surprise, AZ. This is the bar a Electrical pro has to clear before we route any quote request to them in Surprise.

1. 1

   Verify the AZ ROC C-11 license at the state source

   Pull the contractor's AZ ROC C-11 number and verify it's active and qualifier-matched at the state licensing portal. Any pro routing quotes to Surprise (85374) must carry an active license; a lapsed or qualifier-mismatched license is the single most common red flag we filter at intake.

2. 2

   Pull a current Certificate of Insurance

   Ask for a COI naming you as Certificate Holder, with $1M general liability minimum. The COI must be emailed by the agent directly, not a photo of a card. We refresh COIs annually for every Electrical pro on our network serving Sun City Grand and Marley Park.

3. 3

   Read Google reviews, filter for the last 12 months

   4.5 stars with 50+ reviews is the floor we use. Filter for reviews mentioning Surprise or nearby Marley Park so you see the recent local pattern, not a 5-year-old reputation from elsewhere in the metro. Patterns of "didn't return calls" or "left job unfinished" across 3+ reviews predict the same outcome.

4. 4

   Confirm trade-specific certifications for Electrical Panel Upgrade

   Journeyman or master electrician status. NEC code-cycle awareness (2020 minimum, 2023 in newer jurisdictions). Solar and EV-ready continuing education. A pro working Surprise routes who can't name their certifications by acronym usually doesn't carry them.

5. 5

   Verify permit-pull history in Surprise

   Every Electrical job over the local trigger threshold requires a permit. Maricopa County publishes residential permit pulls in its open-data portal; cross-reference the contractor against pulls near Surprise Stadium. A pro with zero permits pulled in the 85378 corridor over the last 90 days is likely skipping them, which costs you on resale and insurance claims.
