Here's the harsh truth: most HVAC failures take place because someone skipped a step. Failed to calculate the load correctly. Used cheap equipment. Got wrong the insulation needs. We've fixed countless of these failures. And every time, we remember another learning. Like in 2017, when we began adding smart thermostats to every system. Why? Because Sarah, our senior tech, got sick of watching homeowners waste money on inefficient temperature settings. Now clients save $500+ yearly.
