EV CHARGER INSTALL ESTIMATING.

## EV Charger Estimating in Phoenix Moves Fast — Your Bids Should Too Phoenix is one of the fastest-growing EV markets in the country. Maricopa County added more than 40,000 registered EVs in a single recent year, and the Arizona Department of Transportation has logged consistent double-digit growth in EV registrations statewide. For you as an EV charger installer, that means a full pipeline — but also a lot of bids to get out the door. Slowing down on paperwork is not an option when three other electricians are quoting the same job. ### What Makes EV Charger Estimating Different in Phoenix **Utility interconnect is not optional.** APS (Arizona Public Service) and SRP (Salt River Project) each have their own EV time-of-use rate structures and service upgrade review processes. Your scope-of-work needs to reflect which utility serves the address. A bid that ignores potential panel upgrades — common in the older ranch homes and 1970s–1990s subdivisions across Scottsdale, Chandler, and Tempe — will lose money or lose the customer when surprises surface. **Load calculations matter here.** Phoenix summers push residential HVAC systems hard. A 200A panel serving a 3-ton or 4-ton AC unit, an electric water heater, and a pool pump may have little headroom for a 48A Level 2 charger circuit. NEC 625.40 requires a dedicated branch circuit. Article 220 demand load calculations are non-negotiable on most AHJ submittals in the Valley. **Conduit runs get long.** Single-story ranch homes with attached garages sometimes have panels on the opposite wall from the garage. Phoenix slab construction means no basement routing. Longer EMT or RMC runs, additional wire pull footage, and proper heat-rated conductors for attic segments all affect your material cost. These are line items that generic estimating tools miss. **Permit fees vary by jurisdiction.** The City of Phoenix, Mesa, Scottsdale, Chandler, Gilbert, Tempe, Glendale, and Peoria each process permits through separate AHJ offices with different fee schedules. A flat-rate estimate built in one city may be off by $75–$200 in permit fees alone when you cross a city boundary. ### How Estimate.Pro Handles EV Jobs Start a walkthrough on any job — residential EVSE retrofit, commercial fleet charging bay, multi-unit EVSE rough-in. The AR measurement tool (ONNX-assisted on supported devices) captures conduit run distances and panel locations. Camera or photo measurements are flagged as estimates so you know exactly what has field verification and what does not. Once you complete the walkthrough, the AI scope generator produces a NEC 625-aligned scope of work: dedicated circuit sizing, conduit material and routing method, GFCI requirements per NEC 625.54, and load calculation notes tied to Article 220. You review, adjust for the specific utility territory (APS vs. SRP), and price against your saved material cost workspace. Median time from walkthrough start to a sendable bid: 8 minutes. ### Pricing That Fits a Solo Installer or a Crew - **Free tier** — no credit card, no time limit. Build bids, send proposals. - **Pro — $39/seat/month** — full AR measurement, saved cost workspaces, proposal exports. - **Elite — $79/seat/month** — Stripe Connect invoicing (0% platform fee), invoice exports, advanced workflows. - **Crew — $399/month flat** — unlimited seats for larger electrical shops running multiple EVSE techs. The Free tier processes payments via Stripe Connect at 3% platform fee. Pro and Elite drop that to 0%. ### The Bottom Line for Phoenix EV Installers Phoenix's growth is real, and EVSE work is a durable revenue line for licensed electrical contractors. The jobs are not complicated, but the bids need to be precise — utility territory, panel headroom, conduit routing, and AHJ permit fees all move the number. Estimate.Pro gives you a structured walkthrough that catches those variables before you submit, not after you've already committed to a price. Start free. No credit card.
