Every call answered. Every quote followed up.
Stellenflow builds AI systems for South African aircon, HVAC and plumbing businesses that reply to every enquiry in seconds, chase every quote and keep your service book full, even while you're on the tools.
Where HVAC and plumbing businesses lose jobs
You're good at the work. The problem is that the work happens on roofs, in ceilings and under sinks, far away from the phone, the inbox and the quote that needs chasing.
AI call answering & lead capture
Missed calls get an instant WhatsApp reply. New leads are qualified and booked while you work.

Same business. Same team. A very different day.
Automation doesn't replace your people. It takes the repetitive work off their plate so nothing, and no one, slips through.
A day on the tools
- 07:00On site by seven. The phone in the bakkie rings three times. Missed.
- 11:30One caller rings back, irritated. The other two went to a competitor.
- 14:00Last week's R18 000 quote still hasn't been followed up.
- 19:30The evening disappears into quotes, invoices and call-backs.
- 21:00Last summer's install customers are due a service. Nobody reminds them.
The same day, with Stellenflow
- 07:05Missed call? The customer gets a WhatsApp reply within seconds, with a booking link.
- 09:00The assistant qualifies the lead: aircon or geyser, suburb, how urgent.
- 12:00Day-three quote follow-up goes out automatically. The customer accepts.
- 16:00Job complete. The invoice and a Google review request go out.
- 19:30Home for dinner. Tomorrow's jobs are already confirmed.
Questions owners ask us
Straight answers. If yours isn't here, ask us during your free audit.
Do you work with plumbers as well as aircon businesses?
Yes. Aircon, HVAC and plumbing businesses share the same challenge: you're on the tools when the phone rings. The systems we build work for call-outs, installs, maintenance and geyser jobs alike.
Does it work with my job management software?
We connect with the tools you already run on, whether that's job-management software, Google Calendar, a spreadsheet or WhatsApp groups. If it holds your jobs and customers, we can usually work with it.
What happens with emergency call-outs like a burst geyser?
You decide the rules. Urgent words like burst, leak or no hot water can trigger an immediate alert to whoever is on call, so emergencies reach a person in seconds.
Can the assistant give customers prices?
Only the prices you approve, like your call-out fee or a starting price for a standard service. It never makes up a quote. Anything that needs a site visit is booked as a site visit.
I'm a one-person business. Is this for me?
That's often where it helps most. When you're the person doing the work and the person answering the phone, every missed call is a missed job. Automation covers the phone while you're busy.
