Venting Portable Air Conditioner In Fireplace

Venting Portable Air Conditioner Through Fireplace: Essential Considerations

Portable air conditioners provide a convenient way to cool specific rooms without installing permanent window units. However, venting these units through a fireplace presents unique challenges that require careful consideration.

The main concern when venting a portable air conditioner through a fireplace is ensuring adequate airflow. The exhaust hose from the air conditioner must have a clear and unobstructed path to the outside to prevent backflow and overheating. If the fireplace has a damper or flue, it must be fully opened to allow the exhaust to escape.

Safety is another crucial aspect to address. The exhaust hose should never be placed near combustible materials, such as curtains or furniture. It's also important to ensure that the hose is not kinked or crushed, as this can restrict airflow and damage the air conditioner.

To minimize the loss of cooled air, consider using a Ventloc or similar device to seal around the exhaust hose and prevent drafts from outside. This will help maintain the cooled temperature in the room.

Fireplace chimneys are typically designed for venting combustion gases, which are relatively lightweight. The cooler and heavier exhaust from an air conditioner may not rise as effectively through the chimney. In some cases, a draft inducer blower may be necessary to assist with exhaust flow.

Finally, remember that venting a portable air conditioner through a fireplace is not a permanent solution. It's a temporary measure that should only be used when other venting options are not available. For long-term cooling needs, consider installing a dedicated window air conditioner or a central air conditioning system.
