This is the harsh truth: most HVAC failures occur because someone ignored a step. Didn't calculate the load properly. Used incorrect equipment. Miscalculated the insulation needs. We've personally fixed hundreds of these disasters. And each time, we remember another lesson. Like in 2017, when we began adding WiFi controls to each installation. Why? Because Sarah, our lead tech, got frustrated of watching homeowners lose money on bad temperature management. Now clients save $500+ yearly.
