A questionable-looking connection on a newly installed gas dryer vent prompted online concern after a homeowner noticed the duct appeared crumpled where it met the exterior vent and asked if the setup posed any real risk.
Here's what to know
After checking the installation, the poster wrote, "Just had this gas dryer installed by Best Buy and I inspected around and saw the vent looked like it is crumpled at the junction where the vent connects to the outside vent." They then asked, "Is this of any concern or am I being overly cautious?" In the ensuing Reddit thread, commenters largely treated it as a problem worth addressing.
Concern centered on the quality of the install and on the fact that it was a gas appliance. One commenter said, "Installers could have slid the flex hose further up, but that would have taken an extra 30 seconds. Make them come back and fix it." Another warned, "And they said gas dryer. That vent is leaking combustion exhaust like carbon monoxide into OPs house if not corrected."
A separate commenter focused on the practical effect of the gap, writing, "It's not right. You will have lint and warm moist air escaping through that gap. I'd attempt to make a better seal."
More background
A dryer vent's job is to move hot, humid air outside, and with a gas model that also means venting combustion byproducts. When the duct is bent, crushed, or not securely connected, airflow can suffer, drying can become less efficient, and lint can accumulate in the wrong places.
A blocked or restricted vent can increase the risk of a fire, and leaking warm, moisture-laden air can create indoor humidity issues. In this case, commenters were particularly concerned that a faulty connection on a gas dryer could allow fumes to spill back into the home rather than vent them outdoors.

A dryer that has to work harder because of poor airflow will consume more energy, driving up household utility costs and increasing the pollution associated with that extra power or fuel use.
What can be done?
A vent that appears dented or improperly connected should not be ignored. When a duct is visibly crushed, partly detached, or bent too sharply, having it checked and fixed is safer than treating it as a cosmetic issue.
The poster suggested they might take care of it themselves, replying, "Thanks, I'm worried they aren't gonna do a good job so I'm just gonna unhook it and fix it myself." Even so, although some vent tweaks may look straightforward, extra care is warranted when the appliance is gas.
