Publisher Description
Run a professional residential load calculation from the driveway, and leave with a report your customer can hold.
LaserCalc is an HVAC load calculation tool for contractors, technicians, and engineers working in the United States. Calculations follow the Manual J 8th Edition methodology and draw on 2025 ASHRAE climatic design data covering thousands of US cities and weather stations.
THREE WAYS TO MEASURE A HOME
. Block Load - we look up the home's square footage from the address. The fastest path to a number.
. Scan Rooms with Camera - walk the house and capture square footage, ceiling height, and windows as you go.
. Enter Rooms Manually - full control over room size, ceiling height, exposed walls, and windows by direction.
REPORTS YOU CAN HAND OVER
. Shareable PDF reports, sent from your phone before you pull out of the drive
. Add your company logo to every report
. Heating and cooling loads with recommended capacity in BTU and tons
YOUR BOOK OF BUSINESS, EVERYWHERE
. Clients and load calcs save automatically and follow you across devices
. Start an estimate on your phone, finish it on your tablet
PRO
. Room-by-room load calcs for tighter equipment sizing
. Automatic room scanning with LiDAR or your camera (LiDAR requires a Pro Apple device)
Available in English and Spanish. The app follows your device language, and you can switch it any time in Settings.
LaserCalc is built for properties in the United States - address lookup and climate data cover the US only.

Version History Version 2.0.2
Fixes an occasional freeze when navigating through the load calc wizard
Version 2.0 adds LaserCalc Pro.
PRO: SCAN A ROOM WITH LiDAR
Walk the room and let the phone measure it. LiDAR picks up the walls, the ceiling height, and the windows while you move, so a room is done in seconds. No tape measure, no notepad, no typing it in afterward. LiDAR scanning needs an iPhone Pro or an iPad Pro.
PRO: SCAN A ROOM WITH YOUR CAMERA
No LiDAR on your phone? Use the camera instead. Aim at each corner of the room and tap. You get the same room-by-room numbers on any device that runs LaserCalc, and it is a genuine alternative, not a consolation prize.
PRO: ROOM-BY-ROOM REPORTS
A heating and cooling load for every room, not one number for the whole house. That is what sizes the equipment and balances the ducts, and it goes straight into the PDF you hand your customer.
NEW FOR EVERYONE
More than 2,700 ASHRAE cities. Odds are the town you are standing in is on the list now, with its own design temperatures instead of the nearest big city's.
LaserCalc speaks Spanish. The app follows your device language, and you can switch it any time in Settings.
New questions in the load calc: number of floors, ventilation and combustion air, duct system layout, and fireplaces. Each one feeds a Manual J load the calc could not see before.
The address lookup fills in more for you. Along with square footage it now pulls stories, fireplaces, floor type, and occupancy from the property record when they are on file. Every one of them stays yours to change.
Closer to Manual J. Two-story infiltration, per-fireplace infiltration, graduated duct factors, and the MJ8AE appliance allowances are all figured the way the spec asks for them.
