Here's the brutal truth: the majority of HVAC failures happen because someone missed a step. Failed to calculate the load properly. Used incorrect equipment. Misjudged the insulation needs. We've personally fixed countless of these messes. And each 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 lose money on poor temperature control. Now clients save 20-30% yearly.
