Let me share the brutal truth: most HVAC failures occur because someone missed a step. Didn't calculate the load properly. Used cheap equipment. Got wrong the insulation needs. We've fixed hundreds of these failures. And every time, we remember another lesson. Like in 2017, when we decided on adding smart thermostats to all installation. Why? Because Sarah, our master tech, got tired of watching homeowners waste money on inefficient temperature settings. Now clients save $500+ yearly. https://www.divephotoguide.com/user/bandarzhje/
