Let me share the brutal truth: nearly all HVAC failures happen because someone missed a step. Didn't calculate the load properly. Used cheap equipment. Miscalculated the insulation needs. We have fixed dozens of these failures. And every time, we record another lesson. Like in 2017, when we started adding smart thermostats to all install. Why? Because Sarah, our lead tech, got frustrated of watching homeowners lose money on poor temperature settings. Now clients save 20-30% yearly.
