Let me share the harsh truth: most HVAC failures take place because someone missed a step. Failed to calculate the load accurately. Used undersized equipment. Misjudged the insulation needs. We've personally fixed hundreds of these disasters. And each time, we file away another learning. Like in 2017, when we decided on adding remote monitoring to all installation. Why? Because Sarah, our lead tech, got sick of watching homeowners burn money on bad temperature control. Now clients save $500+ yearly. https://hashnode.com/@productairheating
