Portable Air Conditioner Exhaust Hose Gets Hot

A portable air conditioner works by releasing humid air into the atmosphere and then releasing it through the exhaust pipe to regulate the temperature of any room. Because of the hot air going through it during the cooling process, the hose gets warm.

However, if the portable air conditioner exhaust hose gets hot than typical, there must be a problem. So, what’s the problem, and how can you solve that? We’ll help you understand why your portable AC exhaust hose gets hot and what to do about it.

5 Reasons Your Portable Air Conditioner Exhaust Hose Gets Hot

Dirt and Dust Accumulation in the Air Filters

You can anticipate dirt and dust to accumulate in the air filters of a portable air conditioner after extended use. If you do so, your air conditioner will begin to break down. It could make a noise or cause the exhaust hose to overheat. Dirty filters can also result in frost buildup on your portable AC. The best solution for this is to clean your portable AC filters regularly. You can replace them if they’re non-washable air filters. Clean filters will ensure the condenser coils and evaporator gets enough air supply helping them work effectively.

Cleaning the filters varies according to the manufacturer’s instructions, but most recommend doing this after 2-3 months.

Inappropriate Venting

Although venting traditionally occurs through the window, there are several options a portable AC can get rid of the heat. A portable air conditioner can use an exhaust hose to eliminate the heat it collects from its environment.

Nonetheless, the venting has to be done properly to ensure it works well. This requires you to use the recommended venting kits for your portable AC. You also need to properly install the exhaust vent, to help channel out all the heat from the room without exerting strain on the AC.

While installing the exhaust vent, consider its diameter, the hose length, and how close it is to the power output. But you shouldn’t interfere with the hose’s length and diameter, as this can alter how your portable AC works. Doing this can result in your portable AC heating up and causing damage to its internal parts.

Wrong Choice of Size of Air Conditioners

Before buying a portable air conditioner, you need to consider the size of your room. It will help you in identifying the right size of portable air conditioner that will meet your cooling demands. Having a smaller AC for a bigger room and vice versa will make your system experience challenges during the cooling process.

To avoid such issues, check the BTU ratings of your portable AC, which varies from each system. Note that having a higher BTU rating isn’t a solution. A portable AC with a higher BTU rating than what’s required will make your system keep shutting off and on, which can make it overwork.

But this doesn’t mean you should have a portable AC with a lower BTU rating that will not meet your room need. A portable air conditioner with a lower BTU rating in a bigger room will result in poor cooling results, and you’ll not meet the desired comfort you’d wish for.

The AC will not also keep up with the room’s high heat load, making it overheat in the process. This means you should measure your room’s size in square foot and record it before going to buy your portable AC.

You should also have detailed information about how many people occupy your house, the house’s ceiling height, and sunlight conditions. These details are vital in getting the right size of portable AC that will not strain to meet your comfort.

Frost and Ice Buildup

As your portable AC removes heat from the atmosphere, moisture from within can cool and freeze on the coil. When there’s a huge accumulation of ice on the coils, it will result in a blockage which will affect how your portable AC works.

This will lead to hot vents and undesired temperatures in the house, making you uncomfortable. Your portable AC will also consume a lot of power in the process as it struggles to keep up with the condition. Frost buildup will also cause regular shutting off, making your system fail to work at all. It can also result in refrigerant leakage, which is an essential component in the cooling process as it filters out heat. Without enough refrigerant in your portable AC, it will fail to cool your room as required.

To reduce the frost buildup in your system, remove things like plants or furniture around it that prevents airflow. This is because evaporator and condenser coils depend on adequate airflow to work effectively. You should also monitor your portable AC to identify damaged parts which require repair and clean the dirty areas which interfere with free airflow.

The Exhaust Hose Isn’t Insulated

Usually, most portable air conditioners exhaust heat through the exhaust hose. But when the exhaust hose isn’t insulated, it will radiate the heat passing through it, making it hot. You can use duct wrap to insulate your exhaust hose if it’s not wrapped.

The duct wrap will prevent heat transmission between the exhaust hose and the surrounding outer surfaces. Most portable air conditioners have easy-to-install exhaust hose covers, which you can also remove and wash.

Using Ventless Air Conditioner Is An Alternative Option

An excellent portable and ventless air conditioner can keep you cool in any area you want, with or without window access, for a reasonable price. A ventless portable air conditioner can best be described as a compact air cooling system with no exhaust hose that can be easily carried from one location to another. The ventless air conditioner is an AC unit that doesn’t require a vent through the window in order to function properly. The installation of a ventless portable air conditioner doesn’t need installation and doesn’t require professionals to install. It cooled air by drawing hot air from the room and passing it over water cooling pads, where the water evaporates into the air and absorbs the heat from the air molecules. The fan then circulates the colder air throughout your space. There are numerous options available, but selecting the finest ventless portable air conditioner is extremely challenging.

Here we listed of few ventless portable air conditioners based on popularity and efficiency. But we always advise you to talk with professionals or do some research before making any purchase.

Bottom line

The reasons why your portable air conditioner exhaust hose gets hot could be a simple thing, most of which you can be in control of. Regularly clean your portable AC’s filter, place it in a good place that doesn’t restrict airflow, and properly vent the exhaust. Alternatively, check to confirm if the BTU ratings of your portable fit the type of room, you’re going to use it on before buying it. If the exhaust hose isn’t insulated, get the right cover and prevent it from radiating heat from its environment.

If none of the above solutions works for your portable AC, call a technician and let them diagnose the problem. You can also consider returning your portable AC to its manufacturer if its warranty period is still active.
