Demo Guide

Walk the field-service capture flow as a housing-authority technician. Tap any step to jump.

What this shows: every mechanical and energy system carries a persistent Harmelo identity. Field service looks up that identity, attaches a standardized service event, and never creates a duplicate — so an owner keeps an unbroken history per asset, across contractors and across years.
// One registry · Every stakeholder's view

Service notes become cold, hard facts

A CRM tracks relationships. A CMMS tracks work orders. Both reset the moment the owner changes. A registry is asset-centric — the record belongs to the system itself and survives every ownership change, contractor rotation, and platform migration.

The Trades

Contractors · Technicians

Every signed entry builds a verified record that follows you across customers, ownership changes, and jobs. Show up to a 2am call already knowing the full service history, isolation points, and access path. Reputation compounds; warranties stay valid.

Government

Cities · Public Agencies · Housing

An inspector pulls up to a 1970s boiler and already knows the last three visits, compliance status, and the first-responder shutoff — before opening a laptop. Public-housing accountability, auditable emissions, and capital planning grounded in continuous lifecycle data.

Portfolios & Developers

REITs · Multi-Site Operators

Open Monday's review and see 40 buildings at once — which systems are aging, which contractors actually perform, which manufacturers deliver. Capital forecasting on standardized data, not spreadsheet theater. Disclosure packages assemble in minutes, not weeks.

Venues

Stadiums · Arenas · Convention Centers

The head of operations can prove every number in the ESG report. Every HVAC unit, chiller, and generator carries a signed, timestamped service history. Emissions pull from verified operating data, not estimates — the answer to an auditor is a record, not a narrative.

Capital

Insurers · Lenders · Underwriters

A claim verifies itself against a signed service history. Property risk has always been priced on roofs and locations; the registry turns mechanical and energy systems into structured, verifiable data — the first underwriting-grade dataset for an opaque asset class.

Owners & Homeowners

Residential · Asset Holders

List a property and the record goes with it. HVAC, water heater, every furnace service — the file lives with the asset, not the owner. Buyers see condition, history, warranty status, and remaining life. The work invested shows up in what the asset is worth.
