What does a conversation handled by the AI look like?
Example conversation
AI agent for the maintenance company
Customer: The building's elevator stopped with a person inside. Are you coming now?
AI agent: Call opened as a priority. Give me the building, the equipment and how many people are in the car.
AI agent: Everything is going in writing to the on-call technician now.
Is an AI agent or manual service better for elevator maintenance companies?
The agent wins at repeated tasks, and a person keeps winning at what takes judgment. With manual service, someone at the maintenance company has to stop what they're doing; with the CertuAI agent the answer goes out on its own and you join the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Call at night or on a holiday | Depends on someone waking up and checking their phone | Answered right away, with building, equipment and situation recorded, and the on-call technician alerted |
| Passenger trapped in the car | The information arrives half-complete, by voice message, with no address | The agent first asks whether anyone is inside and marks the call as a priority |
| Identifying which building the call is from | The condo manager writes from a personal phone and nobody knows which condominium it is | The contact is already linked to the building and the contract in the CRM |
| Monthly preventive maintenance | Booked by phone, rescheduled by phone | The agent confirms the date with the condo manager and records the acceptance in writing |
| Contract proposal request | Sits in the inbox until someone in sales sees it | Qualified right away, with number of stops and equipment brand, and it becomes a deal in the CRM |

In three steps, on the same day. No installation, no code and no changing the number clients already know.
Teach your business
In one conversation, you explain services, prices, hours and rules, as you would to a new employee.

Answers right away, schedules, does follow-up, and records each contact in the built-in CRM. You take over any conversation whenever you want.

Create the agent, connect WhatsApp and see it working at your maintenance company.
Create my agentWhat needs to be ready before turning on the agent at a maintenance company?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The list of buildings under contract, with number of stops, brand and model of each piece of equipment
- What counts as an emergency and what is a routine call, starting with a passenger trapped in the car
- Who is on call in each time slot and how the priority call reaches that person
- The price of a one-off call, what the contract covers and what is charged separately
- The preventive maintenance date for each building and who confirms it for the condominium
- What the company does about reports, ART (technical responsibility record) and inspections, and what stays with the condo manager
Whether the agent alerts the on-call technician on its own when there is a passenger in the car or whether every alert goes through a coordinator first.
The most common mistake: Letting the agent handle a call with a trapped person entirely on its own. That conversation has to reach someone within seconds, and the agent's only job there is to collect the building and situation and pass them on in the same message. Read how to fix this.
Frequently asked questions about elevator maintenance
Does the agent resolve the call on its own?
No. It answers right away, collects the building, equipment and situation and hands it to your on-call technician. The person who goes to the building is still your crew.
Does it know how to tell an emergency from a routine call?
Yes, by the rules you set. A passenger trapped in the car, for example, can be marked as a priority and alert the on-call technician right away.
Does it work for a company with many condominiums?
Yes. Each building becomes a contact linked to the contract in the CRM, and the call history stays with it.
Does the agent do technical reports or inspections?
No. Technical reports, ART (technical responsibility record) and inspections are your crew's technical work. The agent handles the customer service, the records and the schedule.
Does the agent give the monthly contract price over WhatsApp?
It doesn't give a final price, and it shouldn't. A monthly contract depends on the number of stops, the equipment brand, how many elevators the building has and what the company covers. The agent asks all of that, records the address and hands over the ready request so sales can put together the proposal.
In what other fields does the CertuAI agent work?
In any business that serves customers on WhatsApp, because the Brain is written by you. These fields have a day-to-day closest to yours.
Where can I read more about CertuAI's WhatsApp agent?
These pages explain the same agent from another angle: how it works, price, common questions and comparisons between platforms.
In short
A stopped elevator is a call at night and on Sundays. The agent asks for the building and what happened, alerts the on-call technician and records the call in the CRM.
