Here’s the ugly truth: the majority of HVAC failures happen because someone ignored a step. Failed to calculate the load correctly. Used undersized equipment. Miscalculated the insulation needs. We’ve personally fixed countless of these disasters. And every time, we record another insight. Like in 2017, when we began adding smart thermostats to every install. Why? Because Sarah, our senior tech, got frustrated of watching homeowners burn money on poor temperature control. Now clients save 20-30% yearly.
