I went on a service call today to replace a bathroom exhaust fan.What i found was amazing.
The worse hack work i have ever seen for a ventilation system.
These people have respiratory Issues.
They have the air tank with hose they walk around with.
Our POCO sponsors a power smart program which is contracted out.
10 years ago these people spent the money to use the existing bathroom vent fan opening .
What the so called contractor did was wired a timer and a humidistat into an in-line exhaust fan that they mounted in the Attic.
The duct work was horrible the fan was mounted on a truss brace with flexible ducting .
the intake side is 4 inch insulated plastic flex duct . the exhaust side of the fan was 6 in insulated plastic flex duct.
What they did was run the 6 inch stuff about 12 ft away from the fan unit and it was placed between the truss support and because it was flexible as soon as the moisture started to gather in the duct the weight of the water just made all the ductwork sagged between the truss supports this fan could not exhaust any of the moist air to the outside as the duct was full of water.
The inline fan was full of water and all the exsiting ductwork is contaminated with mould.
I feel the whole system needs replacing. This is a side by side duplex the bathroom is on the same wall the divides the 2 units and it is about an 15 ft or so run out to the gable end for the vent cover.
Now should this replacement systen still run horizontal or is it better to have it go staight up and though the roof.
I fell bad for these people as they piad good money from a sponsered program but this system could never of worked properly .
other question is to do this properly how many hours with new duct work and a fan. the wiring seems to be fine.
