Here's the ugly truth: nearly all HVAC failures occur because someone missed a step. Did not calculate the load correctly. Used undersized equipment. Misjudged the insulation needs. We've fixed hundreds of these messes. And each time, we remember another lesson. Like in 2017, when we decided on adding WiFi controls to all installation. Why? Because Sarah, our master tech, got tired of watching homeowners lose money on inefficient temperature control. Now clients save $500+ yearly. https://www.b2bco.com/productairheating
