Here's the brutal truth: nearly all HVAC failures happen because someone skipped a step. Failed to calculate the load properly. Used cheap equipment. Miscalculated the insulation needs. We have fixed hundreds of these failures. And each time, we remember another lesson. Like in 2017, when we decided on adding WiFi controls to all install. Why? Because Sarah, our lead tech, got tired of watching homeowners waste money on poor temperature management. Now clients save $500+ yearly.
