Let me share the harsh truth: nearly all HVAC failures happen because someone ignored a step. Failed to calculate the load correctly. Used cheap equipment. Miscalculated the insulation needs. We have fixed dozens of these disasters. And each and every time, we file away another learning. Like in 2017, when we decided on adding remote monitoring to all system. Why? Because Sarah, our senior tech, got sick of watching homeowners lose money on inefficient temperature management. Now clients save hundreds yearly.
