Let me share the ugly truth: most HVAC failures happen because someone skipped a step. Failed to calculate the load properly. Used incorrect equipment. Miscalculated the insulation needs. We've fixed hundreds of these messes. And every time, we remember another lesson. Like in 2017, when we decided on adding smart thermostats to all install. Why? Because Sarah, our lead tech, got sick of watching homeowners burn money on poor temperature control. Now clients save $500+ yearly. https://replit.com/@productair
