Here's the harsh truth: the majority of HVAC failures happen because someone ignored a step. Did not calculate the load correctly. Used incorrect equipment. Got wrong the insulation needs. We've personally fixed hundreds of these failures. And each and every time, we remember another insight. Like in 2017, when we started adding smart thermostats to every system. Why? Because Sarah, our lead tech, got frustrated of watching homeowners lose money on poor temperature management. Now clients save $500+ yearly.
