Case Studies
See how real small businesses are recovering thousands in missed revenue, booking more appointments, and scaling their operations with Human Add AI.
Summit Mechanical Services
Denver, CO — 12 employees, residential & commercial HVAC
The Challenge
Summit Mechanical was losing an estimated 35% of inbound calls after 5 PM and on weekends. Their answering service took messages but couldn't schedule emergency visits or quote ballpark prices. Callers were hanging up and calling competitors who answered live.
The Solution
Human Add AI deployed a custom-trained voice receptionist that answers after-hours calls, triages emergency vs. routine requests, provides estimated pricing for common services, and books next-day appointments directly into their ServiceTitan calendar.
"We had no idea how much money was walking out the door every night. The AI picks up in two rings, knows our pricing, and books the job. Last month alone it captured $8,400 in work we would have lost to competitors."
-- Mike Torrance, Owner, Summit Mechanical Services
Bright Smile Family Dental
Scottsdale, AZ — 3 dentists, 2 hygienists, general & cosmetic dentistry
The Challenge
The front desk team was overwhelmed. During peak hours (10 AM - 2 PM), 40% of incoming calls went to voicemail. New patient inquiries were being lost, and existing patients were frustrated with hold times. Hiring another receptionist would cost $42,000/year plus benefits.
The Solution
Human Add AI was trained on Bright Smile's services, insurance accepted, office hours, and provider availability. It handles overflow calls during peak hours and all calls outside business hours -- booking cleanings, consultations, and emergency visits directly into their Dentrix calendar.
"We went from losing almost half our calls during lunch rush to booking 47 more appointments every month. The AI even handles insurance questions -- patients can't tell the difference. Best investment we've made this year."
-- Dr. Rachel Nguyen, DDS, Owner, Bright Smile Family Dental
Caldwell & Associates
Atlanta, GA — 4-attorney personal injury firm
The Challenge
The firm was spending $6,500/month on a legal intake call center that asked basic scripted questions. Lead quality was poor -- attorneys were wasting 15+ hours/week on consultations with unqualified prospects. Meanwhile, high-value calls after 6 PM went straight to a generic voicemail.
The Solution
Human Add AI built a custom intake flow that asks about accident type, date, injuries, medical treatment, insurance status, and statute of limitations. It scores leads in real-time, texts hot leads directly to attorneys, and schedules consultations for qualified prospects -- 24/7, including weekends.
"We replaced a $6,500/month call center with an AI that does a better job. It qualifies leads so precisely that our attorneys went from 15 wasted hours a week on bad consultations to nearly zero. The 3x increase in qualified leads is just the cherry on top."
-- James Caldwell, Managing Partner, Caldwell & Associates
FlowRight Plumbing Co.
Tampa, FL — 8 technicians, residential plumbing & drain service
The Challenge
FlowRight's owner, Dave, was personally fielding calls until 10 PM. Their voicemail had a 12% callback rate -- meaning 88% of after-hours callers never became customers. Google reviews mentioned "impossible to reach" and "never calls back," dragging their rating down to 3.6 stars.
The Solution
Human Add AI replaced their voicemail entirely. Every call is answered live by AI that can diagnose urgency (burst pipe vs. dripping faucet), dispatch emergency techs, book next-day appointments, and send callers a text confirmation. Dave got his evenings back.
"I was chained to my phone 16 hours a day. Now the AI handles everything -- and callers actually prefer it because they get instant answers instead of leaving a voicemail into the void. Our Google rating went from 3.6 to 4.8 in four months."
-- Dave Kowalski, Owner, FlowRight Plumbing Co.
Precision Auto Care
Houston, TX — 6-bay independent repair shop, ASE certified
The Challenge
Located in a heavily bilingual neighborhood, Precision Auto Care was losing Spanish-speaking customers because their single front-desk employee only spoke English. Hiring a bilingual receptionist proved difficult -- they lost three candidates to larger dealerships offering higher pay. Meanwhile, their mechanics were pulling off jobs to answer phones.
The Solution
Human Add AI deployed a bilingual (English + Spanish) voice receptionist trained on Precision's services, pricing, and appointment availability. The AI detects the caller's language automatically and switches seamlessly. It books oil changes, brake jobs, diagnostics, and provides status updates on vehicles already in the shop.
"We tried for eight months to hire a bilingual receptionist. Human Add AI solved it in two days. Now 38% of our calls come in Spanish and every single one gets handled perfectly. Our customer base grew 40% in the first quarter -- mostly from word of mouth in the Spanish-speaking community."
-- Carlos Medina, Owner, Precision Auto Care
