What these numbers say about HVAC in St. Louis

By record count, HVAC is the third largest of the 11 trades this site counts in St. Louis, behind landscaping and ahead of roofing. That ordering is a property of the source data's categories rather than a judgement about which trade matters most in St. Louis.

Per resident, St. Louis sits close to the Missouri rate for HVAC, so the count at the top of this page reads as ordinary for the state.

The independent share of St. Louis's HVAC records is close to the Missouri figure, so the mix of independent, franchise-brand and corporate-owned records here is ordinary for the state.

Far fewer of St. Louis's HVAC records are missing a street address than across Missouri.

Missouri publishes no business-level licence source for HVAC that a listing can be matched against, so the licensed share for St. Louis is shown as not published rather than as zero, and no HVAC record on this page is described one way or the other on the strength of a file that does not exist.

No licence issuance or lapse figure is published for HVAC in St. Louis, so no churn figure appears on this page rather than a zero standing in for one.

The occupational series the Bureau of Labor Statistics publishes for this trade counts 2,980 workers across St. Louis, and this site publishes 810 HVAC records here. The two count different things, one an occupation across every employer and the other the businesses on this site, so they stand side by side rather than one against the other.

Of the St. Louis HVAC records that are not independent, corporate-owned locations outnumber franchise brands.

Almost none of St. Louis's HVAC records are waiting on chain review, so the independent, franchise and corporate counts above describe nearly the whole list.

More HVAC records first appeared in St. Louis over the last twelve months than were flagged closed, so the file for this trade and metro grew. A record appears when the source learns of a business, which is a different event from a business opening.

No city inside St. Louis differs from the metro enough on HVAC to carry a page of its own, so every record here is answered on this page.

Among the 3 Missouri metro areas this site publishes a HVAC page for, St. Louis carries the most records per resident. The field is the metro areas this site publishes a HVAC page for rather than every metro area in Missouri.

Ordered by HVAC records per resident across every metro area this site publishes a HVAC page for, the hubs either side of St. Louis are Baton Rouge above it and Springfield below it.
