Here's the harsh truth: the majority of HVAC failures happen because someone missed a step. Failed to calculate the load correctly. Used incorrect equipment. Miscalculated the insulation needs. We've personally fixed dozens of these messes. And each and every time, we file away another insight. Like in 2017, when we decided on adding remote monitoring to every install. Why? Because Sarah, our senior tech, got sick of watching homeowners burn money on inefficient temperature settings. Now clients save $500+ yearly.
