One click: the AI reads the data plate and writes the model and serial number for you.

Photograph the label on a water heater, furnace, AC condenser or appliance. With one click on Generate, InspectorData puts the brand, model number, serial number, manufacture date and capacity into the comment, copied exactly as printed.

Copied, never guessed

Short answer: yes, InspectorData can read a serial number from a photo. Put the data-plate photo on its finding, click Generate or Re-Generate, and the comment includes the model number, serial number, manufacture date and capacity exactly as printed. Unreadable characters become "?", and no number is ever invented.

Typing serial numbers is the slowest part of a mechanical section

Every inspector knows it: you crouch for the photo, then squint at it again at your desk.

Zooming and retyping

Long model and serial strings get copied one character at a time from a small, glare-prone photo.

One wrong character

An O typed as a 0 or a 1 as an I sends your client to the wrong recall or age lookup.

Every system, every report

Water heater, furnace, condenser, panel, dishwasher, range, refrigerator: it adds up on every job.

How it works

There is nothing new to learn. It runs from the same Generate / Re-Generate button you already use in Step 3, Build Report.

  • 1. Photograph the label - with the InspectorData phone app, or upload it to the report.
  • 2. Keep it on its finding - for example Plumbing > Water Heater or Heating > Furnace.
  • 3. Click Generate or Re-Generate - the comment comes back with the brand, model, serial, date and capacity in it.
  • 4. Glance and send - the photo sits right next to the text, so checking the numbers takes seconds.
When a character is unreadable
Serial No. (glare)21?9A123456
... Serial: 21?9A123456 ... (the "?" tells you exactly which character to check)

The rules it follows on every label

Built for report accuracy first. A wrong number in a report is worse than no number.

Copied exactly

Letters and digits are kept apart: O and 0, I and 1, S and 5, B and 8. Spaces and dashes stay where the label has them.

Never invented

It never completes or guesses a number. If a character can't be read, it writes "?" in its place.

The details that matter

Manufacture date and capacity or rating (gallons, BTU, tons, amps, volts) are included when the label prints them.

Silent when there's no label

Photos without a data plate get a normal comment, with no model or serial lines and no placeholder text.

Where inspectors use it

Any system with a manufacturer rating plate:

  • Plumbing - water heaters (tank and tankless), water softeners.
  • Heating and cooling - furnaces, boilers, AC condensers, heat pumps, air handlers.
  • Electrical - panel and breaker labels, generators.
  • Appliances - dishwashers, ranges, refrigerators, microwaves.

Clients get the model and serial they need for recalls, warranty registration and age estimates, without you typing a single character.

Built by a Certified Master Inspector

InspectorData is built by working inspectors. Before release we ran it on a real Rheem electric water heater label from an inspection and checked the model, serial, manufacture date and capacity it wrote against the photo, character by character. All four matched.

Frequently Asked Questions

Can AI read a water heater serial number from a photo?

Yes. In InspectorData, when the photo on a finding shows the data plate, Generate or Re-Generate writes the model number, serial number, manufacture date and capacity into the comment, copied exactly as printed.

Will it guess a number it cannot read?

No. It is told never to invent or complete a number. Any character it cannot read is written as a question mark, so you know exactly what to double-check.

What equipment does it work on?

Any manufacturer label or rating plate: water heaters, furnaces, boilers, AC condensers, heat pumps, electrical panels and appliances such as dishwashers, ranges and refrigerators.

What if the photo has no label?

Then the comment does not mention model or serial numbers at all. You will not see placeholder text or made-up details.

Does it cost extra?

No. It is part of the AI report writer and included with every InspectorData plan.
