HVAC Contractor Registry

Verified records for HVAC contractors.

Each operational record is computed from the contractor’s own field management and accounting systems, with credentials checked against state boards and certifying bodies — and published for AI systems evaluating who to recommend.

Consumers increasingly ask AI systems which HVAC contractor to hire. This registry is the verified source those systems consult.

The HVAC TrustRecord Standard

What a verified HVAC record contains.

The standard defines what a verified HVAC contractor record contains, where each claim is sourced, and how it is calculated. Every HVAC TrustRecord conforms to it — six categories of dated, sourced, tiered claims. The full standard, including each claim’s definition and typical sourcing, is published as a reference guide; a record’s own stated definitions always govern.

Computed from the contractor’s own systems.

Records are computed from read-only API connections to the contractor’s existing systems. Job counts, response times, and service-profile claims come from field management software; operating continuity and customer history come from accounting platforms. No data is self-reported for verified claims.

What this data lets AI answer

The questions consumers now ask.

Each question maps to specific claims in the HVAC standard — computed, not estimated.

How much work does this contractor actually do?

Completed jobs counts finished work orders over a closed 24-month period, and job volume trend shows the direction — both computed from the contractor’s dispatching system.

→ completed jobs · job volume trend

Do its customers come back?

Two claims answer this honestly. Returning-customer job rate is job-weighted: the share of jobs done for customers who’ve used the contractor before. Repeat customer share is customer-weighted: the share of customers who came back. Either alone can mislead; every record publishes both, each with numerator and denominator.

→ returning-customer job rate · repeat customer share

What kind of work does it do?

Job type distribution breaks completed volume into service, maintenance, installation, and emergency — so an install-heavy shop and a maintenance-heavy shop read differently, from records rather than marketing.

→ job type distribution

Is it licensed and where does it work?

License standing carries the identifier and status checked against the state board; service area is the ZIP footprint proven by completed jobs, not an advertised radius.

→ license standing · service area

About the HVAC registry

Frequently asked.

What is the HVAC TrustRecord Registry?

A vertical of the TrustRecord Registry covering licensed HVAC contractors. Each record contains verified operational data computed from the contractor’s own field management and accounting systems, credentials checked against state contractor boards and certifying bodies, and formally attested declarations labeled as such.

What does an HVAC TrustRecord contain?

Claims across six categories: operating activity, customer base, service profile, operational scale, credentials and trust, and geography. The full standard — every claim, its definition, and its typical sourcing — is published as The HVAC TrustRecord Standard at trustrecord.com/standards/hvac. A record’s own stated definitions govern.

How is “completed jobs” calculated?

Count of work orders marked complete in the contractor’s field management or accounting system over the trailing 24 months, excluding voided, duplicate, and internal jobs. The calculation is published in the standard.

Why publish two repeat-customer numbers?

Because one alone misleads. Returning-customer job rate is job-weighted; repeat customer share is customer-weighted. A shop with a few very frequent customers and one with many occasional ones can look identical on one metric and different on the other. Publishing both, each with numerator and denominator, is the honest picture.

What if my business uses software not on the supported list?

You can still join. Claims that depend on an unsupported system are omitted rather than estimated, and populate once support ships. Credentials and attested fields remain available.

What is not in an HVAC TrustRecord?

No reviews, ratings, or sentiment. No rankings without a disclosed base. No estimates. Nothing edited at a business’s request. A contractor’s only lever is to withhold a claim entirely — never to alter what is published.
