Here's the ugly truth: most HVAC failures occur because someone ignored a step. Failed to calculate the load properly. Used cheap equipment. Miscalculated the insulation needs. We have fixed hundreds of these messes. And every time, we record another learning. Like in 2017, when we began adding WiFi controls to all installation. Why? Because Sarah, our master tech, got frustrated of watching homeowners waste money on bad temperature settings. Now clients save $500+ yearly.
