Permanent Load Reduction Case Study #2: The Hunt for the Hidden Comfort Thief

In Permanent Load Reduction Case Study #1, we revealed the Hidden Comfort Thief — building problems that quietly steal HVAC performance. In Permanent Load Reduction Case Study #2, we go on the hunt. The homeowner complaint looked like a typical HVAC problem: the system ran constantly but comfort was still inconsistent. But Permanent Load Reduction always starts with a different question: Where is the load really coming from? The investigation led to the attic where two major issues were discovered working together: • attic duct leakage • uncontrolled air infiltration When supply ducts leak into an unconditioned attic, conditioned air escapes before it reaches the living space. At the same time, the house pulls replacement air through infiltration pathways in the building envelope. This interaction increases heating and cooling loads and can make properly sized equipment appear undersized. Permanent Load Reduction focuses on fixing the root cause of the load rather than oversizing HVAC equipment to compensate for building defects. This case study walks through the investigation and explains how duct leakage and infiltration can quietly increase HVAC loads.
