Dryer Vent Air Leak - Spot, Fix & Maintenance

Dryer Vent Air Leak – Spot, Fix & Maintenance

Dryer vents aren’t ridiculously high on most people’s to-do lists for home repairs. People rarely make lists in the first place unless anything significant happens!

However, particularly during long and difficult cold seasons, these essential and often well-hidden items bear an unexpected share of the responsibility for keeping your house warm, dry, and secure.

Sometimes you might face that your dryer is letting not only all hot air out of your house but also letting in all the cold air inside too. That’s a red flag for you and you need to figure why and how that’s happening and take measurements accordingly.

In this article learn everything you need to know regarding your dryer vent when it lets all the air escape from your house and also lets all kinds of air inside.

Signs That Dryer Vent Needs Servicing

Even the most cautious homeowners frequently overlook these mainly two red flags of an ignored dryer vent. Sometimes, this is since many of us don’t think about or discuss dryer vent operation, so we do not know what to look for.

Dryer vent Working Like a Cooler

Once you open your vacant dryer in the cold season, does that feel cold? If that’s the case, you might have presumed that’s just because it’s chilly outside.

However, the actual reason can be a poorly locked or unsealed vent that allows cold air back into your residence. As a result, your dryer becomes one of the most energy-inefficient appliances in your home.

The Dryer Begins to Make Lint Hoops

You’ll know there’s a heavy amount of stored-up lint inside the dryer vent and depth inside the drying chamber device if you start to find soft and fluffy debris on the pinnacle, inside and behind your drying chamber. Beware that this might cause fire breakouts. 

Besides keeping your lint traps neat and checking behind the device, you can take preventive measures before you see lint beads emerge.


Tasks For Fixing & Maintaining Dryer Vent

If you have unintentionally discovered yourself nodding in agreement as you read the earlier section, your dryer and vent system requires help or servicing.

Now that you’re aware of the problems, what to do about them?

Here’s what to do to get your dryer working better for the rest of the cold weather, using less energy to do the very same task, and functioning much more confidently.

Hire a Professional to Clean Your Dryer Vents

Is it vital to hire a professional to clean your dryer vents? Yes, and here’s why.

There are much other lint traps deep in the nooks and crannies of your dryer that you can’t easily reach, besides the front lint trap that you presumably clean after each dryer process.

Just think of how much captured lint must be inside the inner vents if you have never serviced it; whereas ideally the dryer lint trap should be cleaned weekly. 

It’s quite evident why dryers that aren’t correctly maintained cause so many house fires each year.


A skilled dryer vent cleaning service uses the same promotional vacuum technique to sweep out your air vents.

This method eliminates all stuck objects and disinfects the ductwork safely, eliminating the risk of a home fire and reviving your dryer to peak performance. If the dryer vent isn’t sealed properly they can seal it efficiently too which will solve most of the issues regarding airflows and air leakage.

Conceal the Dryer Vent

Remember the last time you inspected your dryer vent’s seals? Most dryers are vented to the outdoors.

Either way, if the seal that belts the dryer vent is missing or has been damaged, frosty air will completely flash over into your dryer and your household then.

Whereas if part of your vent that exhausts to the outside of your home has airfoils, they may not be thick enough just to survive the impact of chilly winds, mainly due to seasonal storm surges. If that’s the scenario, you may have to protect them with something much more powerful.

Ensure that the Dryer Vent is Clean

Lastly, if you can’t remember the last time you cleaned out the lint in your dryer vent, now is a great time to do so!

Lint, debris, and trapped particles accumulate inside and across the vent’s rim, mostly so much so that users are surprised to find them.

This is certainly relevant if the final part of your active vent has a strainer that originates from the dryer. The filter can become jammed with lint to the point where it fails to let any more air through, resulting in highly combustible lint blocking into the dryer.

It’s hazardous. If you have the time, you can disassemble your vent and give it a thorough cleaning and sanitizing outside. Alternatively, you can have it done by our dryer vent cleaning experts as part of your vent cleaning service.


Trapped dryer vent flaps or faulty sealants are common causes of hot and cold air drafts in your house.

During the winter season, drafts force your heater to work harder to warm the house, potentially increasing your heating bill.

Insects and rodents can also get into your home through gaps caused by a poor sealant.

Several solutions may work, but you can replace the dryer vent with a dryer vent draft blocker if none of them do.

On the inside of the blocker, there is a shuttle that rises when warm air blows through the dryer vent and closes when the dryer is not used. This prevents cold air from busting through the vent and into your home; if it’s still hard to figure out the actual reason for this, take help from the dryer vent cleaning experts like Dryer Vent HQ.
