Deteriorated flexible air duct. Inner core is exposed where outer vapor barrier and insulation is damaged / missing.

Open joint between sections of rigid ducting.  Extensive air leakage occurs into the attic.

Attic insulation is has been blown into the emergency drain pan below the air handler unit, preventing it from working. Only the edge of the pan is now visible.

Due to a poorly fitted access cover (removed), an extensive amount of dust and filth has accumulated around this air handler blower.

Two sections of a fireplace chimney are separated where transitioning up into the enclosure over the roof.  A Fire hazard.

A cap is missing from the flue vent for the gas water heater.  Rain can enter the vent and the vent may not exhaust effectively.

Directly outside of this dining room window is the a gas fired swimming pool heater. Potentially hazardous exhaust may easily enter into the home if the window were opened.

A clothes dryer duct expels air and lint into the attic space.  It is loose from the roof-mounted exhaust canopy. Lint is a potential fire hazard (very combustible).
