Let me share the brutal truth: most HVAC failures happen because someone ignored a step. Failed to calculate the load properly. Used incorrect equipment. Misjudged the insulation needs. We've personally fixed dozens of these messes. And each time, we remember another insight. Like in 2017, when we decided on adding remote monitoring to all install. Why? Because Sarah, our master tech, got tired of watching homeowners lose money on inefficient temperature control. Now clients save $500+ yearly.
