This is the harsh truth: the majority of HVAC failures happen because someone missed a step. Did not calculate the load correctly. Used cheap equipment. Got wrong the insulation needs. We’ve fixed countless of these messes. And each time, we remember another insight. Like in 2017, when we began adding smart thermostats to each system. Why? Because Sarah, our master tech, got tired of watching homeowners burn money on inefficient temperature control. Now clients save $500+ yearly.
