This is the harsh truth: most HVAC failures happen because someone ignored a step. Failed to calculate the load properly. Used cheap equipment. Miscalculated the insulation needs. We've fixed hundreds of these messes. And each time, we file away another lesson. Like in 2017, when we started adding smart thermostats to every system. Why? Because Sarah, our lead tech, got tired of watching homeowners waste money on inefficient temperature control. Now clients save 20-30% yearly.
