Let me share the brutal truth: the majority of HVAC failures happen because someone skipped a step. Failed to calculate the load properly. Used cheap equipment. Miscalculated the insulation needs. We've personally fixed hundreds of these messes. And every time, we remember another learning. Like in 2017, when we decided on adding smart thermostats to all system. Why? Because Sarah, our master tech, got frustrated of watching homeowners burn money on poor temperature management. Now clients save hundreds yearly.
