Where to look

Find the rating plate—a sticker or metal label usually on the front or side of the tank, behind a removable access cover, or underneath a tankless unit.

  • Copy the full line after Model, Model No., or MOD.
  • Copy the full line after Serial, Serial No., or S/N.
  • Do not remove a sealed combustion cover or touch wiring, gas controls, or hot piping.
Label hard to reach or read?

Choose a clear photo and we’ll read the label, then fill in the details for you to review.

Add unit type and fuel if you know them

Your identifiers are excluded from analytics. A selected photo is sent securely to OpenAI for one-time label reading and is not stored by this site.

A useful homeowner report

The answers people actually need.

Equipment identifiers can reveal useful facts, but they cannot inspect a tank. The report explains both the answer and its boundary.

01

Identify and explain

See the manufacturer, model confidence, approximate age, equipment type, capacity, and efficiency facts we can support.

02

Separate matches from maybes

Recall candidates show why they appeared, the hazard described, and exactly what still must be compared.

03

Move to a next step

Get relevant care notes and search for current local help without landing on a disabled service-request form.

Built for people and their agents

A stable answer agents can cite.

The same truth layer powers the website, documented JSON endpoints, and a stateless MCP server. Structured fields carry provenance and confidence instead of burying caveats in prose.

  • Read-only lookup and provider-discovery tools
  • Private agent handoff so you enter your own contact details and consent
  • Explicit-consent direct request as a separate agent write action
  • Stable identifiers, timestamps, source URLs, and limitations
  • No serials, models, ZIP codes, or contact details in analytics

Paid access, without pay-to-play safety.

Providers can pay for workflow and eligible lead access. They cannot purchase their way around geography, capability, licensing review, or the consumer’s stated need.

  • Structured applications and verification queue
  • Constraint-based service request matching
  • Subscription billing after approval
  • Operator-visible status and lead assignment

The source ledger is part of the product.

A fact without provenance is brittle—especially when an agent is making the next decision.
