This is the ugly truth: most HVAC failures occur because someone ignored a step. Didn't calculate the load properly. Used undersized equipment. Miscalculated the insulation needs. We've fixed hundreds of these messes. And every time, we file away another lesson. Like in 2017, when we decided on adding smart thermostats to every installation. Why? Because Sarah, our lead tech, got sick of watching homeowners waste money on inefficient temperature control. Now clients save $500+ yearly.
