Here's the ugly truth: nearly all HVAC failures happen because someone ignored a step. Did not calculate the load properly. Used undersized equipment. Got wrong the insulation needs. We've personally fixed hundreds of these failures. And every time, we file away another insight. Like in 2017, when we began adding smart thermostats to each install. Why? Because Sarah, our senior tech, got tired of watching homeowners lose money on bad temperature control. Now clients save hundreds yearly. https://community.cisco.com/t5/user/viewprofilepage/user-id/1951244
