Let me share the harsh truth: nearly all HVAC failures occur because someone ignored a step. Failed to calculate the load accurately. Used cheap equipment. Misjudged the insulation needs. We've personally fixed countless of these disasters. And every time, we remember another learning. Like in 2017, when we started adding remote monitoring to every system. Why? Because Sarah, our senior tech, got sick of watching homeowners waste money on inefficient temperature management. Now clients save 20-30% yearly. https://community.cisco.com/t5/user/viewprofilepage/user-id/1951244
