Let me share the brutal truth: nearly all HVAC failures take place because someone skipped a step. Didn't calculate the load accurately. Used undersized equipment. Got wrong the insulation needs. We have fixed dozens of these messes. And each time, we remember another learning. Like in 2017, when we began adding remote monitoring to each system. Why? Because Sarah, our lead tech, got sick of watching homeowners burn money on inefficient temperature management. Now clients save $500+ yearly. https://www.blinx.biz/product-air-heating
