This is the brutal truth: most HVAC failures occur because someone ignored a step. Did not calculate the load properly. Used cheap equipment. Misjudged the insulation needs. We have fixed dozens of these failures. And each and every time, we file away another insight. Like in 2017, when we started adding smart thermostats to all system. Why? Because Sarah, our senior tech, got frustrated of watching homeowners burn money on poor temperature control. Now clients save 20-30% yearly.
