Here's the ugly truth: the majority of HVAC failures happen because someone missed a step. Did not calculate the load properly. Used incorrect equipment. Got wrong the insulation needs. We've fixed hundreds of these disasters. And every time, we file away another lesson. Like in 2017, when we decided on adding smart thermostats to every install. Why? Because Sarah, our senior tech, got tired of watching homeowners waste money on poor temperature settings. Now clients save 20-30% yearly.
