What stands out

Counted over the same 7 counties in both years, the metro had 991 plumbing, heating and air-conditioning contractors in 2018 and 982 in 2023 (County Business Patterns).

That is a fall of 0.9%, the 3rd lowest change of the 25 largest metros, where the median is a rise of 9.6% (County Business Patterns).

So there are about as many contractors to compete with as in 2018.

982 plumbing, heating and air-conditioning contractors against 2,834,316 residents in 2023 works out to 3.5 for every 10,000 people, the 6th highest of the 25 largest metros (County Business Patterns, American Community Survey).

That is one plumbing, heating and air-conditioning contractor for every 2,886 residents.

The median of the 25 is 3.3, so this metro has 6% more per resident than the middle one (County Business Patterns).

More contractors per resident means more of them sharing each neighborhood's searches.

Owners live in 760,877 of the metro's occupied homes, 66.7% of them, in the 2024 survey (American Community Survey).

That is the 7th highest share of the 25 largest metros, where the median is 63.4% (American Community Survey).

An owner-occupied home is a household that hires for its own heating and cooling.

What these figures leave out

County Business Patterns counts establishments with paid employees, so a contractor who works with no paid staff is not in these counts (County Business Patterns).

The Census counts HVAC and plumbing contractors together, as plumbing, heating and air-conditioning contractors (NAICS 238220), so every business figure here covers both (NAICS index).

BLS does not publish plumbing and HVAC contractor jobs or their pay for this metro for 2024, because the figures did not meet its disclosure standards (Quarterly Census of Employment and Wages).

BLS stopped publishing metro figures by industry with its third quarter 2025 data, so 2024 is the last full year of them (BLS notice).

None of these figures shows which businesses appear in Google's map results in the Baltimore-Columbia-Towson metro, and we do not measure that.

None of our sources gives what a search ad click costs in this metro. LocaliQ's national averages for Home and Home Improvement are $8.33 a click and $90.92 a lead across its own customers' campaigns, not figures for this metro (LocaliQ).
