This is the harsh truth: most HVAC failures occur because someone ignored a step. Did not calculate the load correctly. Used incorrect equipment. Miscalculated the insulation needs. We've fixed countless of these messes. And every time, we record another lesson. Like in 2017, when we decided on adding smart thermostats to all install. Why? Because Sarah, our senior tech, got sick of watching homeowners waste money on inefficient temperature control. Now clients save $500+ yearly.
