Here's the brutal truth: most HVAC failures happen because someone missed a step. Did not calculate the load correctly. Used undersized equipment. Misjudged the insulation needs. We have fixed dozens of these disasters. And every time, we file away another insight. Like in 2017, when we started adding WiFi controls to every install. Why? Because Sarah, our lead tech, got frustrated of watching homeowners lose money on poor temperature control. Now clients save 20-30% yearly. https://www.hotfrog.com/company/b40e49bda276c776f7d5752f9af104e2/product-air-heating-cooling-and-electric/marysville/home-improvement
