This is the ugly truth: nearly all HVAC failures take place because someone ignored a step. Didn't calculate the load properly. Used undersized equipment. Got wrong the insulation needs. We've fixed dozens of these failures. And each and every time, we file away another learning. Like in 2017, when we started adding WiFi controls to all install. Why? Because Sarah, our senior tech, got tired of watching homeowners waste money on inefficient temperature management. Now clients save 20-30% yearly. https://replit.com/@productair
