The AI voice agent built for HVAC, plumbing, electrical, and roofing call lines

Trade-specific vs general-purpose AI voice

The most important design choice in AI voice for a contractor shop is whether the AI is pre-tuned for the trade or whether the customer has to configure it. General-purpose AI receptionist platforms are flexible by design: you write the prompts, choose the intake questions, set the urgency rules, and integrate the handoff. That flexibility is real value for businesses with strong internal ops.

An AI voice agent for trades makes the opposite choice. The trade questions, the urgency rules, and the handoff format are pre-built into the product for HVAC, plumbing, electrical, and roofing. The customer does not write the trade logic. For most contractor shops, that is the faster on-ramp and the better fit.

Included-minute pricing on contractor phone lines

Emergency calls run longer than routine ones: on the lines OnCrew answers, the median emergency call ran 98 seconds against 55 for a routine call, and the median call 62 seconds, per OnCrew's missed-call statistics. OnCrew counts those minutes: each plan includes a monthly bundle (150, 500, or 1,500 minutes), then $0.49 a minute on Starter, $0.39 on Pro, $0.29 on Multi-Truck, so a 2-minute emergency intake past the bundle is $0.98 on Starter or $0.78 on Pro and Multi-Truck. Calls that end before anyone speaks, recognized robocalls, and your own team's calls never count, minutes are rounded up once a month rather than per call, and the line keeps answering through a storm week.

Real-time urgent triage out of the box

The hardest part of after-hours phone coverage for a contractor is getting the urgent calls to the right person fast. A voicemail captures the call but does not route it. A live receptionist routes it but only as well as the script is written and the operator on duty interprets it. An AI voice agent for trades classifies trade-specific emergencies in real time: no heat in winter, gas smell, active leak, sparking panel with burning smell, storm-damaged roof. The urgent flag fires the same way at 3am as at 3pm, and the alert lands in the channel your team already monitors.

When another tool is the better pick

If you need one platform that handles voice, SMS, WhatsApp, and email together, or outbound calling, a multi-channel platform is the broader fit. OnCrew answers inbound phone calls. It works for any business that takes calls: HVAC, plumbing, electrical, and roofing lines get built-in urgent examples, and every other business gets a general intake.

For HVAC, plumbing, electrical, or roofing shops where the primary need is a real conversation on the phone line with a trade-aware intake and real-time urgent routing, the trade-specific design wins.
