The portable AC pulls in the warm air, cools it and expels the cooled air out in the front of the unit maintaining the temperature of your room and keeping the warm air and moisture out at 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. The easiest and most popular way to vent your portable AC unit is through a nearby window, which is why each and every portable air conditioner we offer on our site includes an easy-to-use window snap kit. 


since most air conditioners contain both a fan and a compressor, but they sound similar to the window ac or a split ac which many of us have heard at some point or the other. before buying you can look at the decibel (dB) unit of the air conditioners which is located on each product description page. But if your current AC unit is making noise, then you can opt form AC services or get it checked and if in case of any problem you can opt for AC repair services.


If you want to find out the energy efficiency of your air conditioners you can look for the five-star rating of your ac units. The higher is the five-star rating of the air conditioner, the more will be the energy saving capacity of your unit. But you want to keep in mind that the efficiency of your air conditioner unit will depend on its condition and status, so it is very important that you keep using regular AC services in order to maintain a good condition of your AC.


Since portable air conditioners pull moisture as well as heat out of the air, many people are concerned about where the water goes. Many units have self-evaporative technology. This innovative technology internally processes and evaporates the collected moisture and then exhausts it out of the back of the unit. In climates that are extra humid, some water may collect in a reservoir located inside the unit. In this case, you can either manually empty the reservoir when it is full or use the integrated gravity drain. With that said, due to recent advancements in portable air conditioner technology, the need to drain is increasingly rare.


Portable air conditioners require regular maintenance and functioning in order to work properly. Draining is a very essential step for the portable air conditioners to work properly and keep it running effectively. The frequency of draining of your portable air conditioners will depend on the condition of the air inside your home and also on the temperature, humidity and air quality index of your area.


Depending on the temperature and humidity of your area you might need to drain your portable air conditioner unit every 8 hour if you used it all day long. 

If you live in a dry area you might not need to drain your portable air conditioner unit so frequently. This is because the water that you fill in your portable AC unit is used to cool down the warm air. The warmness of the air will depend on the humidity of your area. If you live in a dryer area then the AC will not need to drain much moisture and hence you won’t have to drain it much frequently.

However, nowadays modern portable air conditioners units are able to remove the moisture from the air using the exhaust vent. In order to follow this process, the air conditioner sprays water from the condensation tank onto the condensation coils, the condensate comes into contact with the hot condenser coil, it evaporates. The vapor is then blown out of your house through the exhaust hose. Most times, this method is able to get rid of the water from your portable air conditioner’s condensate tank. Only in humid climates will your portable air conditioner’s tank need to be emptied regularly.

Even if you live in a dry area, you need to make it a habit to empty your portable AC’s tank at least once a month. This will remove any residual water. It will also give you a chance to inspect your portable air conditioner’s tank for any signs of mould.


  • Mould will grow in your air conditioner unit-  if you keep the stagnant water for a long period of time in your air conditioner, then there are chances that mould growth and reproduction might occur in the water storage vent of the AC unit without you noticing it.  Mould growth happens especially in portable air conditioners that are not emptied. If water is left inside your portable AC’s tank, it creates a moist environment that is perfect for a mould colony to grow in. In order to prevent this, it is very important that you regularly drain your vent and regularly use AC services for your AC units.
  • The condenser tank can overflow: –   if your portable AC conditioner switch is not working then you may experience the risk of water overflow. This is not a huge problem and can be easily corrected with an AC repair service, but it can cause water damage to your home if ignored for a long term.
  • The portable air conditioner unit will shut off and will not turn back off: – this can be the most common outcome if you do not drain your portable air conditioner unit, as most of the portable AC units have a built-in-float switch. The purpose of the float switch is to turn off the air conditioner if its condensate tank fills up with water. When an air conditioner has a full tank, then it is usually accompanied by an alarm that will alert you of its status. That way, you’ll know it’s time to drain the tank.


  • UNPLUG THE POWER: – before you begin the process of draining your portable air condition unit, it is important that you make sure that it is disconnected from any source of power supply as it can lead to electric shock and will be harmful for you.

  • Set your AC unit in a suitable place: – once you are done with turning off the power supplies of your portable air conditioner unit, you need to find a suitable place where you can discharge the water that you drain from the AC unit.
  • Drain into a pan: once you have unplugged your AC unit, carefully carry it to the sink or bathroom. You can place a pan directly under the draining port, it is generally located in the back of most units. Now you can remove the plug and allow the unit to drain. Be prepared that once you have removed the plug the water will flow freely. When the unit has completely drained you can replace the drain plug and can plug the unit back into the sockets.
  • Drain with a condensate pump:-  condensate pumps are the pumps which can remain plugged in to the AC units and you can drain water from the vent of your portable air conditioner unit. These pumps usually have two hoses, one connected form the pump to the AC unit and the other connected at the pump at open end to drain water. You can place the drainage end of the hose outside the window or into your drainage sink. The condensate pump will automatically turn on once a certain level of water has collected inside the vent of your portable AC unit. It will then automatically turn off once it has drained the majority of water.

  • Drain with a hose: – It is common that now all the AC have a hose option, so you can manually check them before choosing any method for draining your Air conditioner vent. The drain hose can remain attached to a unit and can easily rely on gravity to drain water, meaning the hose must go downhill. Use a drain hose when the AC is in a location with a food drain such as the basement. Before you begin, confirm that the hose fits securely, with a water-tight fit, over the drain port. You may be able to use a standard garden hose, but if that will not fit properly, you can purchase an appropriate hose from a hardware store. Attach your hose to the unit for continual drainage. 
  • Drain into a sink, bathtub or outside:- After unplugging your unit you can carefully carry it to a sink or a bathtub. To avoid leaking, move slowly, keeping it level at all times. Note that your unit surface must sit on a flat surface. Once situated, remove the drain plug and allow the unit to drain. When the unit has completed draining, replace the drain plug, return the unit to its proper location, and plug it back in.

If you want your portable air conditioner to run on a continuous drainage system, then you will need to set up a drain hose. The drain hose will drain water from the tank automatically. One side of the drain hose attached to the condenser tank and the other side goes to a drain. The condensation hose can also be directed outside to drain. Using a drain hose will prevent your condensate tank from accumulating water. With this setup, you won’t need to worry about emptying the condensate tank.
