HVAC After-Hours Recovery

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."

Dental Appointment Booking

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.

Law Firm Lead Qualification

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.

-- James Caldwell, Managing Partner, Caldwell & Associates

Plumbing Customer Experience

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.

-- Dave Kowalski, Owner, FlowRight Plumbing Co.

Auto Repair Bilingual Support

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.

-- Carlos Medina, Owner, Precision Auto Care

What each Human Add AI plan actually includes

Pricing is set up to be predictable, which matters for service operators who hate variable-rate billing on a critical line. The Starter tier sits at $497 monthly and is built around the 100-to-250-calls-per-month operator: a single location, a single booking calendar, and the core AI conversation engine running the intake flow. Everything in Starter is configured during onboarding and tuned by a real human on the Human Add AI side before the agent ever picks up a live call.

Professional at $997 monthly is the tier most established businesses settle into. The volume allowance jumps to 750 answered calls, multi-location routing rules unlock so a single AI receptionist can route calls to the right office, and the integration footprint expands to include the deeper CRM hooks (Salesforce, HubSpot, Pipedrive, Clio Manage, Lawmatics, Dentrix Ascend, Open Dental, Jobber, Housecall Pro, ServiceTitan, FieldEdge, and twenty more). After-hours escalation rules are also standard at this tier.

Enterprise at $1,997 monthly is the high-volume tier with unlimited inbound calls, white-label phone numbers, a dedicated agent-tuning contact at Human Add AI, and direct routing to an on-call dispatcher with priority paths for emergency calls. Outbound calling is also enabled at this tier, billed at fourteen cents per outbound minute against a transparent monthly meter that any operator can cap from the dashboard.

None of the plans use seat counts, per-minute inbound charges, transcript fees, or annual commitments. The whole pricing structure is designed so the operator can predict the bill exactly, and the upgrade path is volume-driven rather than feature-gated. A business graduating from Starter to Professional pays more because they are taking more calls, not because they got locked out of something useful.

The two-day launch path, step by step

From signup to live answering takes roughly 48 hours and follows the same three steps every time. Step one is the onboarding intake. The form asks for the basics (business name, hours, location, phone number to forward), then drops into a vertical-specific section covering the questions a senior receptionist would ask on a typical inbound call. Most operators finish this section in about ten minutes because the questions are the same ones already being asked verbally by the front desk.

Step two is the build. A human at Human Add AI takes the onboarding answers and writes the custom AI receptionist, runs three test calls through the demo line, listens for awkward phrasing or wrong scheduling logic, tunes the voice to the requested tone, and ships back recorded samples for the operator to sign off on. The build typically lands within 24 hours of the intake form being submitted, and the recorded samples include three different scenarios so the operator can hear how the agent handles the easy path and the edge cases.

Step three is the forwarding flip. Once the recorded samples are approved, Human Add AI provides a new phone number and carrier-specific forwarding instructions. The help center has button-by-button guides for Verizon, AT and T, T-Mobile, Spectrum, Comcast Business, RingCentral, OpenPhone, Grasshopper, Vonage, 8x8, Dialpad, and Google Voice. Forwarding takes under five minutes on most carriers and is reversible at any time. The moment the forward is active, the AI receptionist is answering live calls.

Week one after launch is the tuning sprint. The Human Add AI team listens to a random sample of real calls every morning, flags any awkward moments, and adjusts the agent script in place. By the end of week one, the agent sounds like a senior front-desk staffer who has worked at the business for years. Every booking lands on the calendar with full intake details, every qualified lead triggers an SMS to the on-call dispatcher within seconds of the hangup, and the dashboard starts showing the recovered-revenue numbers.

Common questions from service business operators

What does the caller actually hear when they dial my line?

The caller hears a custom greeting in the voice you picked during onboarding (warm, professional, or fast), followed by the agent asking how it can help. The conversation flows naturally, not as a menu tree. The agent introduces itself as part of your team on Starter and Professional plans, and uses your business name as the caller-facing identity on the Enterprise white-label tier. There is no holding music, no "press 1 for sales", and no robotic cadence.

How does the booking calendar integration handle conflicts?

The agent reads live availability against your calendar in real time, which means it never offers a slot that is already taken. If the calendar update happens between the moment the agent reads availability and the moment it confirms the booking (the rare race condition), the platform's conflict handler reverts the booking, texts the operator with both calls, and lets the operator decide which one keeps the slot. In practice this happens roughly once per ten thousand bookings.

What integrations exist for sending the lead summary to my CRM?

Native integrations cover Jobber, Housecall Pro, ServiceTitan, FieldEdge, mHelpDesk, Workiz, RazorSync, ServiceM8 in the field-service world, Salesforce, HubSpot, Pipedrive, Zoho, Close, Copper in the horizontal CRM world, Clio Manage, Lawmatics, Lawyaw, MyCase, Practice Panther, Smokeball in legal, Dentrix Ascend, Open Dental, Eaglesoft, Curve Dental in dental, and twenty other vertical-specific systems. Webhook handoffs cover everything else.

How does the platform handle emergency calls?

Emergency triage is configured during onboarding. The agent recognizes emergency signals in the caller's wording (specific keywords for the vertical, urgency tone, and explicit "this is an emergency" statements), routes the call directly to the on-call dispatcher number, and sends a high-priority SMS in parallel so the dispatcher can see the lead even if they miss the call. The emergency routing happens within the same call (no callback delay), which is critical for service business operators where the first business to answer wins the job.

What does the dashboard show?

The dashboard surfaces every inbound call (with searchable transcripts and recorded MP3), every booking, every SMS lead alert, the recovered-revenue math against your reported average ticket size, the conversion rate from call to booked appointment, the agent's confidence score per call, and the weekly summary email metrics. Operators on Professional and Enterprise also see the multi-location split and the outbound-call meter.

What is the SLA on agent tuning if something needs to change?

Standard tuning requests (script edits, new intake questions, calendar rule changes) are turned around inside 24 business hours on Starter, inside 8 business hours on Professional, and same-business-day on Enterprise. Operators can also self-serve most edits through the dashboard's knowledge base section, which propagates to the live agent within minutes.

How do I know it is actually working?

The weekly summary email shows the count of inbound calls, the count of bookings, the count of SMS lead alerts, the count of qualified leads texted to the dispatcher, and the recovered-revenue math based on the average ticket size reported during onboarding. The dashboard also has a "before / after" comparison view that runs against historical voicemail patterns if the operator imports them, so the lift is visible in dollar terms not just call counts.

Can I try it before committing?

Yes. The public demo line at (617) 812-5251 runs the production agent for a generic service business. Call from any phone and run a real scenario (an actual customer question, an actual scheduling constraint, an actual edge case). The agent will answer, qualify, and offer a real booking slot. The demo gives a faithful preview of what your own customers would experience. No signup, no form, no email collection on the demo path.
