Use AI for speed-to-lead and estimate follow-up, not just phones
HL Bowman
What they did with AI
Pennsylvania HVAC and plumbing company HL Bowman had marketing generating more demand than the office could catch. It deployed four AI pieces together: 24/7 inbound call answering, instant replies to new web inquiries, outbound follow-up on missed calls and unconverted estimates, and automated scheduling. Avoca reports a 100% call answer rate, cost per conversion falling from $350 to $215, and 70% year-over-year revenue growth (which the vendor attributes to better capture and conversion across the funnel).

Move AI from overflow to front-line call answering, step by step
High Ground Service Pros
High Ground (about 150 employees across NJ, NH and ME) started with AI only on overflow and after-hours calls in place of voicemail. It then moved AI to the front line one day a week, then two, then all five, with warm transfers to CSRs for escalations. The company reports AI now handles 75% of inbound calls, the abandon rate fell from 10% to 2%, AI books 81% of bookable calls, $250K-$300K a year in CSR costs were avoided without layoffs, and outbound SMS campaigns bring in $100K-$250K a month.
