Diallux AI notes the problem, asks the right follow-up questions, and books the right engineer — 24/7. Watch it happen, live, below.
We'll set up your live call with the AI within one working day, or call +44 7927 167237.
Actual product — not a mockup. Detail capture, engineer matching and booking, live.
3am, Sunday, mid-job with your hands in a boiler.
Cold snap floods the phones — every caller gets answered. No engaged tone.
Make, model, fault code, symptoms — a fully briefed job, not a message.
Qualified for the fault, near the job, real diary slots — confirmed on the call.
Fault and readings travel with the job. Right parts on the van.
Booked, handled, logged. Your evenings back.
Your website, your price lists, the way you actually talk about the work — it all funnels into your dispatcher.
Not a generic AI receptionist reskinned for your trade — every script, follow-up question and dispatch rule is built around how HVAC and roofing calls actually go. Month-to-month, cancel anytime. Save 10% with annual prepay.
Natural is the whole craft, and it's where we've put the years in. Our developers have spent them on AI prompting and voice behaviour, and the result is a receptionist that holds a genuinely fluid conversation — it listens, asks follow-up questions and answers back like someone who knows your trade, not a phone menu. And the honest bit: yes, people can often tell it's AI — if they ask, it says so. What we've found is that they don't mind, because it sorts their problem there and then: booked, confirmed and in your diary while you're still on the tools. Callers forgive a voice that sounds a little synthetic; they don't forgive a phone that rings out. Judge it yourself — the call playing at the top of this page is the product, not a voice-over.
You should — no software can replace the relationship you have with your customers. Diallux only covers the calls you can't get to, and you set the rules: after-hours only, overflow when you've rung out twice, or everything while you're mid-job — your call. It works around you, never instead of you, and the rules take minutes to change whenever you want.
Put them on your direct list and they'll never hear the AI — their calls come straight through to you. The honest question is what those regulars get today when you're up a ladder or elbow-deep in a cylinder: voicemail, and a promise to call back. With Diallux they're answered in seconds, booked in, and you get a text with everything that's been agreed. Most owners find their regulars prefer a confirmed slot now to a callback maybe tonight.
Three things make it unlikely. It reads your real diary, so it can't book a slot that isn't free. It confirms every detail back to the caller before anything is saved. And every call is transcribed, so if a bad booking ever did slip through, you can see exactly what was said.
About a week for most firms. You give us your website or price list, we build the dispatcher around your services, prices and patch, then we test-call it together until you'd happily let it answer your own mother's boiler. You keep your existing number — callers simply divert to Diallux when you don't pick up. Nothing to install, and nothing for your customers to learn.
Try it for a month. If it doesn't deliver the bookings we agreed, you get a full refund — every penny. If it does, you keep every job it books, and you'll never lose work to a ringing phone again.
