Chicago is expensive to advertise in and easy to waste money in. Cook County alone is huge, and a search from the Loop looks nothing like one from Schaumburg or Aurora.
The collar counties of DuPage, Kane, Lake, and Will each behave like their own market, and traffic on the Eisenhower, the Kennedy, and I-88 decides whether a same-day promise is honest.
Housing mixes two-flats, greystones, condos, and collar-county single-family homes, so a boiler call in Lincoln Park and a furnace call in Naperville are different jobs with different crews.
Winter drives the emergency spike, with the first hard freeze and lake wind pushing heating and pipe calls, while summer storms bring basement water. Trades in the city need City of Chicago and Illinois licenses, and those belong on the landing page.
Budgets are set in dollars.
