Here's the brutal truth: nearly all HVAC failures take place because someone missed a step. Didn't calculate the load accurately. Used incorrect equipment. Got wrong the insulation needs. We have fixed dozens of these disasters. And each and every time, we record another insight. Like in 2017, when we decided on adding WiFi controls to each system. Why? Because Sarah, our senior tech, got frustrated of watching homeowners burn money on bad temperature control. Now clients save 20-30% yearly. https://www.crunchbase.com/organization/product-air-heating-cooling-and-electric
