1) Know what calls you actually get (and what customers say)
Most electrical calls fall into three buckets, and each bucket has a different “urgency” and timing.
1) Emergency: “No power,” “burning smell,” “sparking outlet,” “breaker won’t reset,” “lights flickering,” “I hear buzzing at the panel,” “my service drop got hit,” “storm knocked power out.” These come after storms, during heat waves (AC overloads), and in the evening when homeowners finally notice a warm outlet or a tripping breaker.
2) Scheduled high-ticket: panel upgrade ($3,000–$8,000), whole-house rewiring ($8,000–$20,000), EV charger install ($1,000–$2,500). These callers often phone on lunch breaks (11–1), right after work (4–7), or Saturday mornings. They’re also calling 3–4 electricians for quotes, so speed matters.
3) Small repair / troubleshooting: outlet/switch not working ($150–$300), GFCI keeps tripping, “half the house is out,” “one room has no power,” “my fridge outlet died.” These can happen any time, but you’ll see spikes after people get home.
To optimize hours, you need data. Pull the last 30–60 days of call logs from your phone carrier, Google Business Profile call history, or your CRM. Sort by: day of week, hour of day, missed vs answered, and which calls turned into jobs. Mark the ones that became big tickets (EV charger, panel upgrade, rewiring) so you don’t design hours around low-value tire-kickers.
