No-heat nights don't wait for business hours.
When the furnace quits at 11pm in January, the homeowner isn't filling in a contact form. They're calling, and whoever answers gets a same-week replacement decision. The shops with someone picking up after hours are collecting those winters.
After-hours calls get answered, and the no-heat ones reach you now.
The call is taken, the details are captured, and a no-heat emergency lands on your phone as a text right away, so you decide tonight whether it's a truck roll now or first thing tomorrow. The tune-up request books itself for next week instead. Nobody bounces to the next name on the list.
