Here's the harsh truth: the majority of HVAC failures happen because someone skipped a step. Did not calculate the load properly. Used cheap equipment. Misjudged the insulation needs. We've personally fixed countless of these messes. And each time, we record another insight. Like in 2017, when we decided on adding WiFi controls to each install. Why? Because Sarah, our senior tech, got frustrated of watching homeowners burn money on bad temperature control. Now clients save 20-30% yearly. https://homeguide.com/wa/everett/garage-door-repair/product-air-heating-xhvDmV4PL
