Here’s the ugly truth: nearly all HVAC failures happen because someone missed a step. Did not calculate the load properly. Used cheap equipment. Misjudged the insulation needs. We’ve fixed dozens of these messes. And each and every time, we record another learning. Like in 2017, when we began adding WiFi controls to every system. Why? Because Sarah, our senior tech, got sick of watching homeowners burn money on bad temperature management. Now clients save 20-30% yearly.
