H2C Field

Scan rooms, measure vents, and document HVAC equipment so Hot 2 Cold technicians can arrive prepared.

H2C Field helps document HVAC projects on your iPhone. Create a project, scan individual rooms on a LiDAR-equipped iPhone, review basic blueprints, record vent locations and dimensions, and read equipment labels with the camera.

Project and scan records stay on your device. Guest access supports one local project; optional free email sign-in supports up to three. Signing in does not synchronize projects to another device.

Room scanning requires LiDAR. Vent measurement also offers manual size entry. Check measurements and OCR results before making equipment or installation decisions.

Manage your account and access app support or the privacy policy in Settings. Signed-in users can initiate account and local-project deletion directly in the app.
