Let me share the brutal truth: most HVAC failures occur because someone ignored a step. Did not calculate the load accurately. Used undersized equipment. Miscalculated the insulation needs. We've fixed countless of these messes. And each and every time, we record another learning. Like in 2017, when we started adding smart thermostats to all system. Why? Because Sarah, our senior tech, got tired of watching homeowners lose money on inefficient temperature settings. Now clients save $500+ yearly. https://500px.com/p/productairheating
