PV Project Thermography - Control Home (5/20/98)

Utility Room - AHU Closet

These two photographs of the air handler unit (AUH) door were taken in the control house utility room. As shown in another set of thermography photos, there is an obvious leak in the return duct system that results in hot attic air being sucked into the return air stream. The IR photograph shown below shows the same return leak, but from a different vantage point (the door on the left-hand-side of the photograph leads into the house, while the right-hand-door leads to the garage).

The temperature range is from 72°F (darkest colors) to 90°F (lightest colors).
