Abstract

Avanon deployed a single AI voice agent across 12 home services businesses in the US Southeast and matched its call distribution to a comparable human call center serving the same verticals. Over a rolling 90-day window we captured 10,047 calls through the AI and 9,814 calls through the human benchmark. This paper presents the comparative performance data.

1. Study Design

We deployed identical call routing to both AI and human agents across 12 home services businesses including HVAC, plumbing, electrical, and appliance repair. Calls were randomly assigned to ensure comparable distribution of call types, times, and customer demographics.

4. Conclusions

For standard home services dispatching, the AI is at rough parity with a trained human dispatcher on the metrics that matter to customers, and wins decisively on the coverage metrics that matter to business owners. The right deployment is not replacement. It is overflow during business hours and primary after-hours and weekends.
