Here's the harsh truth: nearly all HVAC failures happen because someone ignored a step. Failed to calculate the load correctly. Used cheap equipment. Misjudged the insulation needs. We have fixed hundreds of these messes. And each and every time, we record another insight. Like in 2017, when we began adding WiFi controls to each installation. Why? Because Sarah, our lead tech, got frustrated of watching homeowners waste money on poor temperature control. Now clients save 20-30% yearly.
