Let me share the ugly truth: most HVAC failures happen because someone ignored a step. Did not calculate the load correctly. Used undersized equipment. Miscalculated the insulation needs. We've personally fixed dozens of these messes. And each time, we record another lesson. Like in 2017, when we began adding WiFi controls to each install. Why? Because Sarah, our lead tech, got frustrated of watching homeowners waste money on inefficient temperature management. Now clients save hundreds yearly. https://vocal.media/authors/product-air-heating-cooling-and-electric
