This is the brutal truth: most HVAC failures occur because someone skipped a step. Didn't calculate the load correctly. Used cheap equipment. Got wrong the insulation needs. We've fixed hundreds of these failures. And each and every time, we record another lesson. Like in 2017, when we started adding smart thermostats to all install. Why? Because Sarah, our lead tech, got sick of watching homeowners burn money on inefficient temperature management. Now clients save $500+ yearly.
