This is the harsh truth: most HVAC failures take place because someone missed a step. Did not calculate the load correctly. Used cheap equipment. Misjudged the insulation needs. We've fixed dozens of these disasters. And each and every time, we file away another insight. Like in 2017, when we decided on adding smart thermostats to every system. Why? Because Sarah, our senior tech, got tired of watching homeowners burn money on poor temperature management. Now clients save hundreds yearly. https://500px.com/p/productairheating
