Torn, Dirty and Poorly Supported Ductwork From Our Inspections

INSPECTION FINDINGS · FROM OUR INSPECTION RECORDS

A comfortable room temperature does not tell us everything about the ductwork serving it. We documented flexible duct with limited support in an attic, substantial debris visible through a return opening and torn-open ducts beneath two different houses. The photographs show why accessible ductwork deserves attention even when the equipment itself is running.

The two torn-duct findings are separate inspection examples. Their similar appearance does not establish the same cause, and I would not identify a particular animal from damaged duct material alone. The report needs to describe the opening and the affected duct, then recommend the appropriate evaluation.

Photographs and documented observations

An unsupported run of attic duct

We found flexible ductwork resting on insulation or running with limited support. Sagging and tight bends can restrict airflow. We recommended that an HVAC contractor evaluate how it was routed and supported.

A return duct loaded with dust and debris

Looking through the return opening revealed a substantial buildup of dust and debris. The report recommended professional cleaning and a properly fitted filter to limit further accumulation.

Something tore into the ductwork

We found damaged ductwork under the home. The tearing appeared consistent with wildlife activity, though the inside of the duct was out of view. We recommended an HVAC contractor evaluate the damaged sections.

Another crawlspace. Another torn-open air duct.

We found ductwork torn open beneath this home, with damage that appeared consistent with wildlife activity. The report recommended an HVAC contractor evaluate the damaged ductwork and repair or replace affected sections.

Look beyond the equipment cabinet

The unsupported attic run raises a routing and support question. The dirty return concerns the condition visible through that opening. The torn ducts involve a break in the intended air-distribution enclosure. Those are different repair tasks, so a general statement that the HVAC system was serviced would not necessarily address all of them.

Match the contractor's work to the finding

The original reports called for HVAC follow-up, correction of damaged ductwork and professional cleaning where substantial accumulation was documented. A contractor should also evaluate the relevant filter and support arrangements. The photographs establish the locations that needed attention; they do not establish that all concealed ducts were in the same condition or that every home requires routine duct cleaning.
