Here's the ugly truth: nearly all HVAC failures happen because someone ignored a step. Didn't calculate the load correctly. Used cheap equipment. Miscalculated the insulation needs. We have fixed dozens of these failures. And each time, we file away another lesson. Like in 2017, when we started adding smart thermostats to each install. Why? Because Sarah, our master tech, got tired of watching homeowners burn money on poor temperature control. Now clients save $500+ yearly. https://groups.google.com/g/electric-motor-it-support/c/v-PiRO2Yugo
