Here's the brutal truth: nearly all HVAC failures happen because someone skipped a step. Did not calculate the load properly. Used undersized equipment. Got wrong the insulation needs. We've personally fixed countless of these messes. And each time, we file away another lesson. Like in 2017, when we began adding remote monitoring to all install. Why? Because Sarah, our senior tech, got tired of watching homeowners burn money on inefficient temperature control. Now clients save $500+ yearly.
