| 内容：Here's the brutal truth: the majority of HVAC failures happen because someone missed a step. Did not calculate the load correctly. Used undersized equipment. Misjudged the insulation needs. We've personally fixed dozens of these messes. And each time, we file away another learning. Like in 2017, when we decided on adding smart thermostats to all system. Why? Because Sarah, our senior tech, got sick of watching homeowners waste money on bad temperature management. Now clients save $500+ yearly.
