Here's the harsh truth: the majority of HVAC failures happen because someone ignored a step. Did not calculate the load correctly. Used incorrect equipment. Misjudged the insulation needs. We've fixed hundreds of these messes. And each and every time, we remember another lesson. Like in 2017, when we started adding WiFi controls to each installation. Why? Because Sarah, our lead tech, got sick of watching homeowners lose money on inefficient temperature settings. Now clients save $500+ yearly. https://homeguide.com/wa/everett/garage-door-repair/product-air-heating-xhvDmV4PL
