Let me share the ugly truth: most HVAC failures occur because someone missed a step. Did not calculate the load accurately. Used undersized equipment. Misjudged the insulation needs. We've personally fixed countless of these disasters. And every time, we file away another insight. Like in 2017, when we decided on adding WiFi controls to each install. Why? Because Sarah, our master tech, got tired of watching homeowners burn money on inefficient temperature control. Now clients save hundreds yearly. https://www.tumblr.com/productairheating2/802845984814153728/product-air-heating-cooling-and-electric?source=share
