Let me share the ugly truth: nearly all HVAC failures happen because someone ignored a step. Failed to calculate the load correctly. Used cheap equipment. Got wrong the insulation needs. Our team has fixed hundreds of these messes. And each and every time, we file away another learning. Like in 2017, when we decided on adding WiFi controls to all install. Why? Because Sarah, our lead tech, got frustrated of watching homeowners burn money on bad temperature control. Now clients save 20-30% yearly. https://www.sqlservercentral.com/forums/user/productairseattle
