This is the harsh truth: the majority of HVAC failures occur because someone ignored a step. Did not calculate the load correctly. Used cheap equipment. Miscalculated the insulation needs. We've fixed dozens of these disasters. And each and every time, we remember another learning. Like in 2017, when we began adding WiFi controls to all install. Why? Because Sarah, our senior tech, got sick of watching homeowners burn money on poor temperature control. Now clients save hundreds yearly.
