The things installers actually ask.

The engine works room by room from fabric, glazing, orientation, occupancy and air change rate, and shows you every component rather than a single number. In this demo build the model is deliberately simplified and clearly labelled as such — a production deployment is calibrated against your regional design conditions and signed off by your own engineer.

Both, side by side, from the same room data. Air conditioning that gets sold on cooling and then used all winter is the normal case, so the number that matters is usually the heating one.

Yes — several indoor units against one condenser, with the combination checked so you don't end up specifying a condenser that can't carry the heads you've drawn. Multi-split and VRF sizing are on Professional and above.

Design one apartment, then roll it across the stack. Forty-four identical flats is one design and forty-four install packs, not forty-four surveys. Block rollout is on Business and above.

Surveys are captured locally and sync when you get a bar back. You can complete a full survey, design and proposal offline; the signature and deposit go through as soon as you reconnect.

Both. The survey and the design tool are built for a tablet held in one hand, but everything works on a phone — and the proposal is designed to be signed on whatever screen is nearest.

You type the dimensions; the plan draws itself to scale. Dragging a wall is for adjusting, not for drawing. Nobody is sketching in CAD on a driveway.

Refrigerant charge, pressure test and commissioning are logged against the job as you do them, so the register is a by-product rather than a Sunday job. Certificates and the customer handover pack generate themselves.

Yes. Equipment cost, labour rate, materials, mark-up and VAT treatment are all yours. The shortlist prices every unit at your installed rate, not a list price.

No. You pay a flat monthly seat price. Payment processing is at cost through the provider you connect.

Straight into your own payment account — card, Klarna or Direct Debit, collected against the signed proposal. The money never sits with us.

Per firm, not per job: Starter £49, Professional £149, Business £299 and Enterprise £599 a month, excluding VAT. All plans include the design tool, proposals, e-signature and payments. Full breakdown on the pricing page.

Yours. The proposal, the online estimate and the customer account all carry your logo, your colours and your terms. FoxFace doesn't appear on anything a customer signs.

It shouldn't — it runs the same engine off the same rate card, so the number a homeowner gets at midnight is the number you'd have given them. Where the survey changes it, it's because the room turned out different, and the customer can see why.

Yes, as an embed. No rebuild, no moving your site. Enquiries land as real jobs in your diary rather than as another form email.

Import customers and open quotes from a spreadsheet on day one. Most firms are running live within a week.

An afternoon, once. Labour rate, materials, mark-up and your usual equipment prices — after that every quote prices itself and you're only adjusting the odd job.

You do. Customers, jobs, designs and documents are yours to export at any time, and you keep read-only access for 30 days after cancelling so nothing gets stranded.

Monthly, cancel any time, no exit fee. The 14-day trial doesn't take a card.
