Commercial HVAC maintenance: HVAC Maintenance Plan Index

Every row is a verbatim sentence read from the named source's own page through our fetch service on the date shown, hash-pinned to the stored read (the sha of the page's visible text; the raw page is mirrored to R2).

6 of the 23 named sources that could be read published a usable figure; 16 published none and are recorded as not published, never filled in; 2 could not be read (blocked, dead or unreachable) and count nowhere.

The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source in USD (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 194 candidate sentence(s) were refused by a reviewer with the reason recorded.

The fuller derivation this dataset is chartered to grow into (not yet what the figures above are; they are each source's own published figure as read): one row per published plan: the tier name, the annual and monthly price, the number of visits, the repair discount, the priority-service promise and the waived diagnostic; the median price per visit derived across plans (which is the figure the customer cannot get anywhere - every firm publishes a plan, nobody publishes what a visit inside one is worth), the residential-versus-commercial split, and the per-unit and per-square-foot commercial benchmark beside it

194 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
