Let me share the harsh truth: the majority of HVAC failures take place because someone ignored a step. Did not calculate the load properly. Used cheap equipment. Miscalculated the insulation needs. We've fixed dozens of these messes. And every time, we file away another learning. Like in 2017, when we began adding remote monitoring to every system. Why? Because Sarah, our master tech, got frustrated of watching homeowners waste money on bad temperature settings. Now clients save $500+ yearly.
