What these numbers say about HVAC in Baltimore-Columbia-Towson

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

Per resident, Baltimore-Columbia-Towson sits close to the Maryland rate for HVAC, so the count at the top of this page reads as ordinary for the state.

The independent share of Baltimore-Columbia-Towson's HVAC records is close to the Maryland figure, so the mix of independent, franchise-brand and corporate-owned records here is ordinary for the state.

Maryland publishes no business-level licence source for HVAC that a listing can be matched against, so the licensed share for Baltimore-Columbia-Towson 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 Baltimore-Columbia-Towson, 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 3,960 workers across Baltimore-Columbia-Towson, and this site publishes 662 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.

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