How To Vent A Portable Air Conditioner Without A Window




portable air conditioner is a device that cools the air in your home, known by other names like 'mini' or 'windowless'. It uses fans to blow cool air into your house through vents installed on the exterior walls of your home or apartment building.

The following are some things you should know about how to vent a portable ac unit without a window:


Why Is Venting Important?

Venting is an essential aspect of using a portable air conditioner. If the hot air produced by the unit is not ventilated properly, it can lead to a variety of issues. For example, the unit may not be able to cool the room effectively, leaving you feeling hot and uncomfortable. Additionally, inadequate ventilation can cause the air conditioner to overheat, which can damage the unit and shorten its lifespan. In some cases, this may even result in increased energy costs as the unit struggles to maintain the desired temperature. For these reasons, it's crucial to ensure that your portable air conditioner is properly vented to promote optimal performance and efficiency.

What are the venting options?

If you have a portable air conditioner and no windows in the room, there are still several options for venting:

  1. Vent through a wall: One option is to vent the air conditioner through a wall. This involves cutting a hole in the wall and installing a vent cover.
  2. Vent through a door: If there are no windows available for venting, you may be able to vent the air conditioner through a door. Simply cut a small hole in the door and install a vent cover.
  3. Vent into another room: If there's another room nearby with a window, you may be able to vent the air conditioner into that room. This can be done by using a duct or hose to connect the air conditioner to the other room.
  4. Vent into a drop ceiling: If the room has a drop ceiling, you may be able to vent the air conditioner into the ceiling space. This can be done by cutting a hole in the ceiling and installing a vent cover.
  5. Vent into a chimney: In some cases, it may be possible to vent the air conditioner into a chimney. However, this should only be done with the help of a professional to ensure proper usage.

It's important to note that some of these options may require more extensive installation work, and it's always a good idea to consult with a professional to ensure the safe and proper venting of your portable air conditioner.



Q: Can You Use a Portable Air Conditioner Without a Window?

A: Yes, it is possible to use a portable air conditioner without a window, but it may require some extra effort and may not be ideal. One way to use a portable air conditioner without a window is to vent it through a drop ceiling by removing a tile and placing the ceiling vent kit's metal insert in that spot to guarantee a snug fit. Another way is to vent it through a sliding door by measuring the vent panel, applying weather strips, and attaching the exhaust hose to the panel. However, it's important to understand how the unit works and how it works best to ensure proper ventilation.


Q: How Long Do Portable Air Conditioners Last?

A: Portable air conditioners typically last around 10 years on average, according to Home Inspection Insider. However, with proper maintenance and upkeep, the lifespan of a portable air conditioner can be extended by up to five additional years. The life expectancy of a portable air conditioner can also be extended by ensuring it has a low cooling load or using it infrequently. If you purchase a high-quality model with removable filters and name-brand internal parts, and keep the unit clean, you can easily get 8 to 10 years of use from them. With exceptional care and maintenance, a portable air conditioner can last up to 15 years or more.


Q: Do All Portable Air Conditioners Need To Get Vented?

A: Yes, all portable air conditioners need to be vented. Portable air conditioners pull in warm air, cool it, and expel the cooled air out of the front of the unit and the remaining warm air and moisture out of the back of the unit. It is this warm air and moisture that needs to be vented out of the room you are currently cooling. Moreover, the heat extracted from the air has to leave your room, otherwise, it will mix up with the cold air again. Ventless air conditioners are a marketing scam and never work.
