Let me share the brutal truth: the majority of HVAC failures happen because someone ignored a step. Failed to calculate the load accurately. Used incorrect equipment. Misjudged the insulation needs. We've fixed hundreds of these messes. And each time, we remember another lesson. Like in 2017, when we started adding WiFi controls to every installation. Why? Because Sarah, our senior tech, got sick of watching homeowners waste money on inefficient temperature settings. Now clients save 20-30% yearly. https://www.bbb.org/us/wa/marysville/profile/refrigeration/product-air-heating-cooling-and-electrical-1296-1000154140
