This is the harsh truth: the majority of HVAC failures occur because someone missed a step. Did not calculate the load properly. Used undersized equipment. Got wrong the insulation needs. We've personally fixed hundreds of these failures. And every time, we file away another learning. Like in 2017, when we began adding smart thermostats to each system. Why? Because Sarah, our lead tech, got tired of watching homeowners lose money on inefficient temperature control. Now clients save hundreds yearly.
