กระทู้: Why We Wire HVAC Systems Backward: The Climate Con

Here's the harsh truth: most HVAC failures happen because someone ignored a step. Did not calculate the load accurately. Used cheap equipment. Got wrong the insulation needs. We have fixed dozens of these disasters. And each time, we record another learning. Like in 2017, when we began adding WiFi controls to every installation. Why? Because Sarah, our lead tech, got sick of watching homeowners burn money on inefficient temperature management. Now clients save 20-30% yearly.
