Should I Close My Chimney Flue During Summer?

As the summer months roll around and the weather warms up, you might find yourself thinking about your fireplace and chimney. Should you close the chimney flue during summer? That’s a great question and one we get asked a lot. Let’s dive into everything you need to know about your chimney flue and whether keeping it open or closed during the summer is the best choice for you.

What is a Chimney Flue?

First things first: what exactly is a chimney flue? The chimney flue is the duct or passageway inside your chimney that allows smoke and gases from your fireplace to escape safely outside your home. When you have a fire burning, the chimney flue is what makes sure all that smoke doesn’t fill your living room.

Why You Might Consider Closing Your Chimney Flue in the Summer

There are several good reasons why you might want to close your chimney flue during the summer months.

1. Energy Efficiency

By keeping the flue open, you’re essentially leaving a big hole in your house. During the summer, this means your cool, air-conditioned air can escape and warm air from outside can come in. This can make it harder to keep your home cool and comfortable. Closing the flue can help you save on energy costs by keeping the cool air inside where it belongs.

2. Preventing Unwanted Pests

An open chimney flue can be an invitation for small animals and insects to make their way into your home. Birds, squirrels, and other critters might see your chimney as the perfect place to set up shop. By closing your flue, you can keep these unwanted guests out.

3. Reducing Moisture

During the summer, humidity levels can be high. An open flue can allow moisture to enter your home, which can lead to unpleasant smells and even mold growth if the moisture gets trapped. Closing the flue helps keep moisture out and protects your home from these potential problems.

4. Avoiding Bad Odors

Sometimes, the smell of your fireplace can waft into your home if the flue is left open, especially during the warmer months when the air is more stagnant. Closing the flue can help keep those smoky, ash-like odors out of your living space.

How to Properly Close Your Chimney Flue

If you’ve decided that closing the flue during the summer sounds like a good idea, it’s important to know how to do it correctly.

1. Locate the Damper

First, find the damper. The damper is a movable plate that covers the flue when it’s closed. It’s usually located at the base of the chimney, just above the firebox. Sometimes it can be a little tricky to find, but a flashlight can help.

2. Close the Damper

Once you’ve located the damper, you’ll need to close it. Most dampers have a handle or a lever that you push or pull to close. Make sure it’s completely shut to prevent air, pests, and moisture from coming in.

3. Check the Seal

After closing the damper, double-check that it’s sealed properly. If you feel any drafts, you might need to adjust it or check for damage. A good seal will keep your home protected.

When to Leave Your Chimney Flue Open

While there are many good reasons to close your chimney flue during the summer, there are also situations where you might want to keep it open.

1. Ongoing Repairs or Cleaning

If you’re having your chimney or fireplace repaired or cleaned, you might need to keep the flue open. This allows for proper ventilation and helps the work get done safely and effectively. Always follow the advice of your chimney repair or sweeping professional.

2. New Construction

For new homes or recent chimney installations, it’s a good idea to follow the guidelines provided by the builders or contractors. They may recommend leaving the flue open for a certain period to allow for curing and proper airflow.

Regular Maintenance is Key

No matter whether you decide to keep your chimney flue open or closed during the summer, regular maintenance is essential. Here’s why:

1. Safety First

A well-maintained chimney and fireplace are crucial for safety. An inspection can catch any issues before they become serious problems, like cracks or blockages that could cause dangerous fumes to back up into your home.

2. Keeping it Clean

Regular chimney sweeping and cleaning help prevent creosote buildup. Creosote is a flammable substance that can accumulate inside your chimney and increase the risk of a chimney fire. Cleaning your chimney at least once a year is a good rule of thumb.

3. Preventing Damage

Regular inspections and maintenance can also help prevent damage. Weather and regular use can take a toll on your chimney’s structure. Catching small issues early can help prevent expensive repairs down the line.
