This is the ugly truth: the majority of HVAC failures happen because someone missed a step. Did not calculate the load accurately. Used incorrect equipment. Misjudged the insulation needs. We have fixed countless of these messes. And each time, we file away another insight. Like in 2017, when we began adding WiFi controls to every installation. Why? Because Sarah, our senior tech, got tired of watching homeowners burn money on bad temperature management. Now clients save 20-30% yearly. https://www.facebook.com/ProductAirandElectric
