This is the harsh truth: most HVAC failures happen because someone skipped a step. Failed to calculate the load correctly. Used undersized equipment. Miscalculated the insulation needs. We've personally fixed dozens of these messes. And every time, we remember another lesson. Like in 2017, when we decided on adding remote monitoring to all system. Why? Because Sarah, our master tech, got sick of watching homeowners waste money on bad temperature management. Now clients save 20-30% yearly.
