One LiDAR walk-round gives every room's cooling load, the unit to quote, the pipe run drawn on the plan and a planning check — on the doorstep, not 48 hours later. Built for F-Gas installers; no EPC knowledge needed.

Room size from the scan, orientation from the compass. Change the window, the use and the people — the unit to quote changes with it. Illustrative steady-state estimate; check against the current guide before you order.
Simplified: fabric + solar gain through glass + people + equipment. Standard sizes, brand-neutral; you choose the model.
For the phone call or the doorstep. The scan already knows the floor area, the glazing and which way it faces — you add room use and people. ±20%, clearly marked as an estimate, never on the order.

Walls and U-values, glass conduction, solar gain by orientation and shading, people, equipment, lighting and air changes. Every line on the report, every assumption named.

Postcode lookup on every job against Historic England's listed-buildings register and the council's conservation-area map. A banner on the survey and a line on the report — before anyone puts a unit on a wall they'll have to take it off.

Tap the indoor wall, draw the pipe run across the plan, drop the outdoor unit where it goes. Metres and bends counted, drain and power ticked, photo stamped at each spot. The installer turns up knowing the job.

Already on Surveyor or Pro? Switch it on
A "project" is one property — every room of it. Heat pump & solar is not available on the Air-con plan; it needs the fabric survey in Surveyor. All plans →
No. It's a CIBSE-style steady-state heat-gain estimate from the surveyed fabric, glazing and use — enough to size and quote. Check the current guide. Inkaroom is a survey tool, not a design accreditation.
Which units does it suggest?Standard sizes, brand-neutral. You pick the model; the report shows the load it must meet and the multi-split outdoor total.
Does it do refrigerant pipework design?No. It records the run — length, bends, route on the plan — for the quote. Pipe sizing and charge stay with the manufacturer's tool.
Does an air-con job plant a tree?No — the tree promise is for heat-pump and solar installs only.
Which iPhone do I need?An iPhone Pro or Pro Max from the 12 Pro onwards, or an iPad Pro with LiDAR. Standard iPhones don't have the scanner.
What does it cost?Air-con is £24.99 a month including VAT for 15 projects, on its own — no EPC or survey plan needed. 14-day free trial on the web, no card. Surveyors on Surveyor or Pro add it for £14.99.
Is the web version different from the app?Air-con is web-first: you scan in the app and the cooling load, unit size and report are on your account. The app's own air-con screens arrive in version 1.1.
14-day free trial. No card. £24.99 a month after.
