Portable air conditioners are a great idea for those who a.) want to enhance their existing cooling systems, b.) may not be allowed to install traditional systems or c.)  find a central cooling system to be too expensive. One of the reasons why many prefer a portable AC is the fact that it can easily be moved to different rooms and doesn’t have to be permanently installed. However, your machine conditioner still requires some minimal setup. For example, you need to make sure that the air conditioner’s hose is secured in place on the unit and to the window tightly.  Simple I know, but a very important factor to keeping your room cool.

It’s also important to know that your unit requires some maintenance for it to work efficiently and stay durable. These machines can be costly so you definitely want to make sure you spend some time and take proper care of the unit. With that being said it doesn’t have to cost you much to maintain your portable AC unit. Plus, most AC’s have similar requirements for maintenance, making your efforts to take care of your cooling system even easier.


Initial venting is one of the most common things that a portable AC requires. Your cooling unit comes with a venting kit that needs to be carefully mounted on a window. Most of these kits are fairly simple to use and don’t take long to setup. If for some reason you don’t have windows, you can also vent the unit through the walls, drop ceiling or dry vent.


Portable air conditioners have a few different ways of dealing with drainage.  Some of the best portable air conditioners evaporate water automatically, while others are required to be drained anywhere from a few hours a day to once a month. Normally, your AC unit releases water during cooling especially in humid weather and this water is collected in a bucket. The intervals for emptying the cooling unit’s bucket depend on how often the system is in use as well as the duration of operation. Most portable AC’s have a connectable hose to help collect the drainage water and a condensing pump which is considered an essential mechanism to help drain the water. This drainage system can be used to drain the water continuously if the unit is in operation for a long time.


Regular cleaning and replacement of filters is another way to properly maintain your unit. Most machines come with washable filters to help them remove particles from the air. In order for these filters to last and work effectively, you should clean them on a bi-weekly or monthly basis. Cleaning these filters can be a breeze if your portable AC has a washable filter. Simply place it in warm water and detergent. Rinse, let dry and then re-insert back into your machine. If your unit has a carbon filter then you need to replace it according to your manufacturer’s instructions.

Last but not least is cleaning the exterior of the unit. If your machines surface area is clean then you maximize your potential air volume.  No special cleaners are required, just a damp cloth should do the trick.

Cleaning your AC isn’t just about preserving performance; it’s about making sure you have clean breathable air in your environment as often as possible.


In the off season, or when you’re not using your machine for an extended period of time. It’s a good idea to store it away somewhere. This will not only preserve its cooling efficiency, but also prolong its overall lifespan. Simply unplug the unit, drain all the water and turn it on fan mode. Perform a final clean of all filters and place your unit in a dry place away from sunlight.
