Here's the ugly truth: the majority of HVAC failures take place because someone missed a step. Did not calculate the load accurately. Used undersized equipment. Got wrong the insulation needs. We've personally fixed dozens of these disasters. And every time, we file away another learning. Like in 2017, when we started adding WiFi controls to each installation. Why? Because Sarah, our lead tech, got frustrated of watching homeowners lose money on bad temperature management. Now clients save 20-30% yearly.
