Why HVAC software is a perfect vertical SaaS case study for sharp positioning

Commercial HVAC software — sold to contractors managing technicians, service calls, maintenance contracts, and dispatch — is a real B2B market where the buyer has money, the workflows are messy, and the language is highly specific. That specificity is exactly what makes it a useful teaching example. The marketing problem isn't 'we need more content.' The real question is: which pain gets the owner to take a demo? Is it dispatch chaos? Late invoices? No visibility into which jobs were profitable until month-end? Or the technician who finishes a service call, spots a replacement opportunity, and the follow-up quote just never gets sent? That last one is interesting precisely because it's specific — and specific beats generic every time.
