Here's the ugly truth: nearly all HVAC failures occur because someone skipped a step. Didn't calculate the load accurately. Used incorrect equipment. Misjudged the insulation needs. We've personally fixed dozens of these disasters. And each and every time, we record another lesson. Like in 2017, when we started adding smart thermostats to each installation. Why? Because Sarah, our senior tech, got frustrated of watching homeowners waste money on bad temperature settings. Now clients save $500+ yearly. https://wakelet.com/@productairheating
