Here's the ugly truth: the majority of HVAC failures occur because someone missed a step. Failed to calculate the load correctly. Used cheap equipment. Miscalculated the insulation needs. We've personally fixed dozens of these messes. And each and every time, we remember another lesson. Like in 2017, when we started adding smart thermostats to all installation. Why? Because Sarah, our senior tech, got frustrated of watching homeowners burn money on bad temperature settings. Now clients save $500+ yearly.
