What these numbers say about HVAC in San Francisco-Oakland-Fremont
By record count, HVAC is the eighth largest of the 11 trades this site counts in San Francisco-Oakland-Fremont, behind painting 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 San Francisco-Oakland-Fremont.
Per resident, San Francisco-Oakland-Fremont sits close to the California rate for HVAC, so the count at the top of this page reads as ordinary for the state.
The independent share of San Francisco-Oakland-Fremont's HVAC records is close to the California figure, so the mix of independent, franchise-brand and corporate-owned records here is ordinary for the state.
Far fewer of San Francisco-Oakland-Fremont's HVAC records are missing a street address than across California.
The share of San Francisco-Oakland-Fremont's HVAC records linking to an active state licence is close to the California figure for the same trade.
Almost every San Francisco-Oakland-Fremont HVAC record sits inside California, the state the licensed share is computed inside, so that share covers nearly the whole metro.
More HVAC licences lapsed in San Francisco-Oakland-Fremont over the last twelve months than were issued. A lapse is a licence that stopped being current, not a business that stopped trading. Both figures come from the state's own status field.

The occupational series the Bureau of Labor Statistics publishes for this trade counts 3,980 workers across San Francisco-Oakland-Fremont, and this site publishes 687 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.
No San Francisco-Oakland-Fremont HVAC record is classified as a franchise brand or a corporate-owned location, so the chain split here is independent records and records still in review.
Almost none of San Francisco-Oakland-Fremont'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 San Francisco-Oakland-Fremont 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.
