Heat Load Calculations in Minutes
HeatLoadPro turns your iPhone Pro or iPad Pro into a professional HVAC tool. Scan rooms with LiDAR, get instant heat load results, and generate client-ready PDF reports — all in one app.
Requires a LiDAR-equipped device — iPhone 12 Pro or later, or a 2020 iPad Pro or later. The LiDAR scanner is only on Pro models, so a standard iPhone or iPad won't work.

See the app
A few of the screens you'll spend the most time in.
Instant scan review
The moment you finish scanning, HeatLoadPro shows you a 3D model of the room with dimensions, floor area, and counts of every wall, window, and door it detected — all measured automatically.
Every wall, annotated for you
Each wall is listed with its compass orientation, dimensions, framing type, and area. Tap Edit to fine-tune materials or Add Opening to log a window or door the scan missed.
Quick insulation editor
Pick an insulation type and HeatLoadPro fills in the standard R-value, or override it with your own measurement. Cleaner than typing values into a Manual J spreadsheet.
From scan to report in 4 steps
No training required. If you can walk around a room, you can use HeatLoadPro.
You'll need a device with a LiDAR scanner — an iPhone 12 Pro or later, or a 2020 iPad Pro or later. LiDAR is only built into Pro models, so a standard iPhone or iPad can't run the room scan.
Create a Project
Start a new project for the job site. Enter the address and design conditions.
Scan Each Room
