Question DetailsAsked on 7/5/2015

Dryer vent duct is disconnected or clogged.

Recently I have hired a company to do dryer/vent duct cleaning and they were able to complete the vent but not able complete the dryer. After running the dryer the technician told us that either the duct pipe might be disconnected or clogged and he is not qualified to fix that types of issues. If anyone have any suggestions who I can reach out to get help to narrow down the issues and fix them is greatly appreciated.

I would say drop that vendor from your list - he certainly should have been able to figure out if the vent pipe was disconnected or broken, or if the dryer itsefl had a clog inside.

For DIY, you could maybe disconnect the duct (flex or metal) at the back of the dryer (especially if electric because easy to disconnect and pull out, not so much slack room with gas dryer due to gas connection) - if you can disconnect the duct where it goes into the floor or wall or at the back of the dryer (usually just press connection unlesss you see a screw-type band clamp holding it on. Then run dryer on Air or Fluff setting to be on the safe side - if air is coming strongly out of the dryer or disconnected duct, should be good to there.

If not, try to see inside with flashlight for blockage - also take out lint screen and shine a light down into there and see if there is a blockage - ditto into the outlet from the dryer if you can slide the ducting off there reasonably. You normally will not be able to see the actual flashlight, but the light beam should show if there is a blockage in the screen housing or in the turns at the bottom back of the dryer where the airflow comes out the back - usually one or two 90 degree turns at the bottom of the lint screen housing.

If all those look good or you can clean them out, hook ducting back up, then run dryer on Air or Fluff (no heat) and check if good airflow is coming out at the dryer vent outlet, if you can get to it.

As for a vendor if you can't DIY - if there is a blockage inside the dryer that you can't clean out yourself (with power cord disconnected, of course) then service call by an Appliance Repairman - Large typically $60-120 range. If that area looks good but you are not getting airflow out the ducts to the outside, then could be kinked or disconnected ducting - which a Heating and A/C contractor is the usual person to use for that (or Handyman if you have one you trust to do it right).

It is possible the cleaning damaged/disconnected a duct, especially if the flex type - that is common. If you have a contractor in to work on the ducting, I would recommend having it (or at least the parts he has to access anyway or can easily reach without tearing into walls and ceilings) replaced with rigid metal ducting as it is much more resistant to the duct cleaning tools and does not kink, plus if fire-resistant in the event of a lint fire.
