Air Conditioner Vent Hose Buying Guide

When it comes to shopping for an air conditioner vent hose, it can be difficult to decide which type is the best for your needs. In this guide, we’ll help you understand what type of vent hose to buy, how to measure for the correct size, and the best materials available. With this knowledge, you’ll be able to easily select the perfect hose for your air conditioner.

Types of Air Conditioner Vent Hoses

The most common types of vent hoses available are flexible plastic and metallic vents. Flexible plastic hoses are often the most affordable and are easy to install. Metals are less common, but are also generally more durable and can handle higher temperatures. The type of vent hose you choose will depend largely on your budget and the air conditioner model.

Measuring for the Correct Size

Correctly measuring for a vent hose is essential for a secure and tight fit. Measure the inside diameter of the vent hose outlet on the back of your air conditioner and the outside diameter of any vent hose you intend to connect. The chosen hose should fit snugly on the inside diameter of the outlet and the outside diameter of the hose should match the wall vent opening.

Material Quality

When selecting material quality, take into account both environmental conditions and safety concerns. In humid areas, a corrosion-resistant option such as corrosion-proof steel or heavy-duty plastic is recommended, while in cold climates, aluminum is recommended. Additionally, look for hoses that are flame-resistant and have no exposed metal edges to prevent potential electrical shorts.


Choosing the right air conditioner vent hose is an important decision and one that can affect the longevity of your air conditioner. Consider the types, measurements and materials when selecting the correct vent hose, and you’ll be able to find the perfect hose for your air conditioner.

Personal Experience

What does AC exhaust hose do?

I was living in a hot, humid climate and constantly running my air conditioner just to keep up with the conditions outside. I soon noticed that the airflow was getting weaker and realized that one of my air conditioner vents, specifically the hose, was blocked and filled with dirt. After months of neglect, I finally decided to take a look at the hose and out my DIY-skills to the test.

At first inspection, it was clear to me that the vent hose was clogged with dirt and dust from the environment. I was able to identify the clog and realized that I needed to open the vent and get rid of all the dust particles. I started by removing the vent cover, which was luckily very easy to do as the screws holding it in place were quite accessible.

After opening the vent, I could now clearly access the dirt and dust that had been blocking the airflow. I used a vacuum cleaner with a convenient hose attachment and **** out all the dirt and debris from the vent. I then used a damp cloth to remove any extra dust particles from the vent and cleaned up the area.

I finally reattached the vent cover and was pleased with the outcome. After this, I could feel the immediate difference in the airflow and a noticable increase in efficiency of the air conditioner. I am sure that if there was a more serious problem, I would have had to call a professional, but luckily this was a fairly simple fix.

Frequently Asked Questions

What does AC exhaust hose do?

AC exhaust hoses are used to release heat and moisture generated by air conditioning systems and eliminate negative pressure inside the system. They draw in fresh air from the outside environment to balance the pressure within the AC system and help it work efficiently. An AC exhaust hose helps keep the air conditioning system running properly and efficiently by releasing that heat and moisture that builds up while cooling the interior of the building.

How do I connect my AC vent hose?

To connect your air conditioner vent hose, first slip the exhaust connector over the discharge opening at the backside of the portable a/c unit. Secure the connector with hose clamps or a tightening band if necessary. Finally, attach the other end of the exhaust hose to a window or wall vent.

What happens if you don’t vent an air conditioner?

Without installing an exhaust vent, an air conditioner cannot cool an area effectively. This is because the warm air produced by the unit would remain in the room and create a cycle between hot-and-humid and cool-and-dry. Not venting the air conditioner will cause it to become inefficient and potentially cause damage to the unit.

How long can the exhaust hose be on a portable air conditioner?

The exhaust hose on a portable air conditioner can usually be up to 5-7 feet long. It is possible to purchase an extension hose to increase the hose length if you need it to be longer. Many online retailers offer longer extension hoses, as well as parts stores and home improvement stores.

Is exhaust hose necessary for portable air conditioner?

No, an exhaust hose is not necessary for a portable air conditioner. However, it is best to use an exhaust hose when running the unit in cooling mode, as this will help remove warm air and moisture from your room. In dehumidifier mode, the air conditioner can be safely run without the exhaust hose, though it may result in the room heating up slightly.

Is the exhaust from a portable air conditioner harmful?

No, the exhaust from a properly functioning portable air conditioner is not harmful. If the unit is functioning properly without any refrigerant leakage, the air leaving the unit will contain only increased temperature, not any hazardous contents. To ensure that no harm comes from the exhaust, it is best to check the unit regularly to make sure it is in good working order.

Is it normal for portable AC exhaust hose to be hot?

Yes, it is normal for the exhaust hose of a portable air conditioner to be hot to the touch. This is because the AC unit is designed to draw warm air from the room and discharge it out the exhaust hose, cooling the room in the process. Thus, the exhaust hose will naturally be warm as it is carrying out hot air from the room.

How do I connect my AC hose to my adapter?

To connect an AC hose to an adapter, start by slipping the exhaust connector over the discharge opening at the backside of the portable a/c unit. Secure the connector to the unit with the included screws. Then attach the exhaust hose to the connector, either with the snap-lock system or clamping tightens with included bands.

What happens if you run a portable air conditioner without an exhaust hose?

When a portable air conditioner is run without an exhaust hose, the AC will recycle the room air by cycling between cool-and-dry and hot-and-humid. This can be inefficient and may increase energy consumption. Additionally, humidity levels in the room may become uncomfortable.

Can you connect two AC hoses together?

Yes, you can connect two AC hoses together using connectors. This will allow you to extend the total length of the exhaust hose and reach the desired destination. All you need to do is select a compatible connector for your exhaust hose depending on the size and type. Make sure to secure the connections to prevent any air leakage.

Final Thoughts

When buying an air conditioner vent hose, you want to make sure you purchase a durable and reliable product. Consider the diameter, length, material, and product reviews before making a purchase to ensure you are getting the best product for your needs. Additionally, it is important to always follow the setup instructions found in your user’s manual and clear out dust or debris that may clog the hose to keep your air conditioner running efficiently and your indoor air quality healthy.
