When I moved, I noticed that the dryer duct outlet in my new home was smaller than at my previous residence.

The outlet on the dryer is about 4-1/2-5" and was such at the old place.

However, the receptacle at the new place is about 3 to 3-1/2" in diameter. Since the move, it takes 2 cycles to dry a load.

I was curious if the reduction in the diameter of the exit plumbing could cause this? Maybe I need to install a larger ducting outlet??



Thanks

Yes it could cause this problem.
A 4 inch pipe is actually 75% larger in cross sectional area than a 3 inch, so there is a big difference in the amount of air it can carry.

Undo the dryer from the exhaust
Run a load
If the load dries correctly then you have a vent problem.
Clean/check the vent system. Make sure the outside louvers open fully.

If you do not want lint in the house.
Take a pair of pantyhose, put one leg into the other and attach this to the dryer exhaust.
Leave enough room behind the dryer so it can blow out like a windsock.
Run a load.

Both the above will allow you to check the air flow and temp.
Also the above is NOT recommended for a gas dryer due to possible carbon monoxide pro
