A room captured by LiDAR as a 3D mesh

01

Walk it once.

Scan the room with LiDAR and every dimension, opening and ceiling height is captured as you pace it out.

02

See it on the wall.

Stand the real unit on the real wall at true size, and settle the position while you are still in the room.

Augmented reality view of a condenser unit on a real brick external wall

03

Agree the outdoor unit.

Put the condenser on the actual brickwork, check clearance and the pipe run, and take the objection off the table.

The tape measure
stays in the van.

Your phone measures the room

LiDAR room scan & ARIn beta

Walk the room. It measures itself.

Point the phone and walk. ARKit RoomPlan builds the room live — walls, ceiling height and every opening — in about the time it takes to pace it out.

Scanning needs an iPhone or iPad Pro with LiDAR. AR unit preview works on any recent iPhone or Android.

Proposal & e-sign

Three options, on the doorstep.

The survey becomes a branded proposal with three priced options, built from your own material and labour packages — and signed on the customer's phone before you leave.

  • Your rates, not ours — every option priced from your own material and labour packages.
  • Signed on any phone — no printing, no posting, no second appointment.
  • Drawings attached — the scaled plan goes out with the price, not after it.

The money is in before the ladders are.

Take the deposit the second they sign — card, Klarna, bank transfer or Direct Debit — and the invoice files itself against the job.

  • Deposit on signature — the money lands before you have packed the ladders away.
  • Four ways to pay — card, Klarna, bank transfer or GoCardless Direct Debit.
  • Parts ordered automatically — an itemised order emailed to your wholesaler.

Oh — and the parts
order themselves.

Questions, answered

Yes — end to end. Manual J heat-load, split and multi-split sizing, refrigerant pipe-run checks, condenser placement, F-Gas and Building Regs-ready drawings and multi-dwelling riser sections. It's not a generic CRM with an HVAC label.
It runs Vento's real Manual J engine — the same code the platform and the mobile app use — client-side in your browser. It assumes a 2.4 m ceiling, two windows and two occupants. A full survey also measures shading, air-tightness, internal gains and pipe routing.
Yes. Proposals are e-signed from any phone, and you can collect a deposit or full payment immediately by card, Klarna, bank transfer or GoCardless Direct Debit.
The whole platform is mobile-first — survey, design, propose and take payment from your phone at the property, even with patchy signal.
Yes — multi-room floor plans, multi-split systems, and block cross-sections showing riser routes, communal plant and fire-compartment crossings.
Your data is isolated per organisation with row-level security, encrypted in transit and at rest, with audit logging and rate limiting throughout.
