Here's the ugly truth: the majority of HVAC failures take place because someone ignored a step. Did not calculate the load properly. Used cheap equipment. Got wrong the insulation needs. We've personally fixed dozens of these messes. And each time, we remember another learning. Like in 2017, when we started adding WiFi controls to all installation. Why? Because Sarah, our master tech, got sick of watching homeowners waste money on inefficient temperature settings. Now clients save $500+ yearly.
