Review method

Selection and review

We selected and coded 36 source publications for this expansion. Sources were chosen for relevance, identifiable authors or operators, and a stated method where available. We checked relevant methods and findings, compared sources, and separated documented facts from our operating recommendations.

This is a targeted, structured evidence review. It is not an exhaustive systematic review or a representative survey of HVAC shops. One reviewer completed the coding without an independent second coder.

Review depth

Long reports and transcripts were reviewed for relevant passages. Podcast notes and webinar recaps are identified in the entries. Vendor cases describe selected experiences, and product documentation describes features rather than how every shop uses them. Client records and private working material are not part of this public register.

Counting sources

Reports and their landing pages count once. Repeated studies do not become additional studies, and repeat appearances by an operator do not become additional people. This count includes revisited material and is specific to this expansion. We do not add populations from different studies together. No original Kopikat interviews were conducted as part of this review.

Overlap and interpretation

Several reports concern the same TECH program, so their samples may overlap. The ServiceTitan report webinar repeats the residential services report survey and adds an operator account. John Wilson appears in both the Owned and Operated interview and the contact center webinar recap. Neither repetition is independent confirmation.

Regional studies, broad home service surveys, and individual accounts have different populations and limits. This review does not establish a national rate of missing homeowner reasons, an average cost of chasing information, or profit caused by a shared record.

How we test what applies in your shop

Earlier exploration

The initial shared estimate context note used selected public discussions and training to identify questions for further research. Its discovery and review counts remain separate from the source register above.

That review screened 25 unique YouTube discovery results, retrieved seven selected transcripts and reviewed relevant passages, revisited selected archived material, read seven Reddit posts with selected comments, and screened 36 public Facebook posts. Many Facebook results were promotions and were not counted as independent outcome evidence. Primary product documentation and trade training were also checked. Anonymous identities were unverified, and captions could contain errors.

This expansion prioritized research reports, named accounts, and official documentation. It added no new Facebook or Reddit material. Public listings whose full reports were unavailable, weakly related material, and generic sales statistics without a verified underlying study were excluded. Unverified totals from older archives are not included in the published count.
