This is the brutal truth: most HVAC failures happen because someone skipped a step. Failed to calculate the load properly. Used incorrect equipment. Misjudged the insulation needs. We've fixed hundreds of these disasters. And every time, we file away another learning. Like in 2017, when we started adding smart thermostats to every install. Why? Because Sarah, our master tech, got sick of watching homeowners lose money on inefficient temperature control. Now clients save 20-30% yearly. https://homeguide.com/wa/everett/garage-door-repair/product-air-heating-xhvDmV4PL
