Let me share the brutal truth: the majority of HVAC failures take place because someone skipped a step. Did not calculate the load accurately. Used cheap equipment. Misjudged the insulation needs. We've personally fixed countless of these disasters. And every time, we file away another lesson. Like in 2017, when we began adding WiFi controls to all installation. Why? Because Sarah, our master tech, got tired of watching homeowners lose money on inefficient temperature settings. Now clients save $500+ yearly. https://www.brownbook.net/business/5457 ... ir-heating
