Why We Wire HVAC Systems Backward: The Climate Control Lesson We Understood at Age A Teenager 投稿者：StevenPet 投稿日：2026/01/13(Tue) 08:22 No.3540790
Let me share the brutal truth: most HVAC failures happen because someone missed a step. Didn't calculate the load correctly. Used cheap equipment. Got wrong the insulation needs. We've fixed dozens of these messes. And every time, we record another insight. Like in 2017, when we started adding WiFi controls to all system. Why? Because Sarah, our senior tech, got tired of watching homeowners burn money on inefficient temperature management. Now clients save hundreds yearly.
