Let me share the harsh truth: nearly all HVAC failures occur because someone ignored a step. Didn't calculate the load accurately. Used undersized equipment. Got wrong the insulation needs. We've personally fixed dozens of these disasters. And each time, we remember another insight. Like in 2017, when we started adding smart thermostats to every installation. Why? Because Sarah, our lead tech, got frustrated of watching homeowners lose money on inefficient temperature control. Now clients save hundreds yearly.
