Recognition is the job, and the emergency call belongs to search
Social is the slow channel. It builds the name a homeowner reaches for later, and it will not fill tomorrow's board.
Same-day and no-heat calls go to whoever is visible at the moment of panic, which means paid search and a map listing. Nothing you post on a Tuesday competes for that moment.
A feed does something different and slower. It makes your company a known quantity in a few neighborhoods, so that when the failure finally happens, or when somebody asks in a group, your name is already familiar.
Judging this by the wrong scoreboard is what kills it in most shops. Three months of posting produces almost nothing you can point at, and the account gets abandoned right before it would have started paying.
Set that expectation with whoever approves the budget on day one. A year is the honest unit of time here, and anyone selling you a quarter is describing a different channel.
