Here's the brutal truth: nearly all HVAC failures occur because someone missed a step. Did not calculate the load correctly. Used incorrect equipment. Got wrong the insulation needs. We've personally fixed dozens of these failures. And every time, we file away another learning. Like in 2017, when we decided on adding smart thermostats to each installation. Why? Because Sarah, our lead tech, got frustrated of watching homeowners waste money on bad temperature management. Now clients save hundreds yearly. https://www.callupcontact.com/b/businessprofile/Product_Air_Heating_Cooling_and_Electric/9904077
