Here's the harsh truth: the majority of HVAC failures happen because someone ignored a step. Didn't calculate the load properly. Used cheap equipment. Got wrong the insulation needs. We've fixed hundreds of these messes. And each time, we remember another insight. Like in 2017, when we began adding smart thermostats to each installation. Why? Because Sarah, our lead tech, got sick of watching homeowners waste money on inefficient temperature settings. Now clients save $500+ yearly. https://www.producthunt.com/@productairheating
