Let me share the harsh truth: the majority of HVAC failures occur because someone ignored a step. Didn't calculate the load accurately. Used cheap equipment. Misjudged the insulation needs. We've fixed dozens of these disasters. And each time, we record another lesson. Like in 2017, when we began adding smart thermostats to all system. Why? Because Sarah, our senior tech, got tired of watching homeowners burn money on bad temperature settings. Now clients save 20-30% yearly. https://hashnode.com/@productairheating |
