What to look for when buying ventless portable air conditioner
Here are the most important aspects to consider before parting with your hard-earned cash and investing in a ventless portable air conditioner.
Coverage area
The cooling capacity of your air conditioner will determine the size of the space that it can effectively cool. There is no point in getting one that is not up to the job of cooling the space you intend to use it in. It will only disappoint you.
Our reviews indicate the coverage area that each model can cool so choose accordingly. Using one that does not have the capacity for the room size will not be effective at keeping you cool.
Portability
Some are more portable than others. Size and weight are important factors. Casters make a heavier unit easier to move around.
Size
Apart from the portability aspect, you also want the air conditioner to be compact so that it does not use up too much space in the room you want to use it. Some models are rather bulky while many are sleek and compact.
Style
As this is a product that is used in your home you want it to look good. Give some thought to the style of your living area. Some air conditioners have a very modern look while some are more basic. Do not get one that looks unpleasant.
Ease of use
You do not want to hassle with the air conditioner. The easier it is to operate, the better. Simple basic controls are all that is needed. LEDs are handy to show you the status of the unit. Remote control is a massive convenience as it allows you to change the settings without getting up.
A digital display is also handy but not essential. Timers and other features add to the convenience of the device.
Noise
You do not want to be disturbed by a loud noisy air conditioner. This is even more important if it is to be used in a bedroom. Some have a sleep mode which is handy. Look for a model that makes minimal noise.
Most manufactures will list the noise level which is normally measured in decibels (dBA). This will allow you to compare the various models. Fortunately, ventless portable air conditioners are one of the quieter cooling options available.
Water Tank Size
This is an important factor as if the tank is too small you will spend a lot of time and energy topping it up.
Price
Some models have design elements or special features that make them more expensive. The more powerful units will also cost a bit more. That is not to say the more affordable options are no good and there are some very well-priced ventless portable air conditioners that do a great job.
FAQs
Here are the answers to a few questions that popped up often during our research.
What are the different ways water is removed from ventless portable air conditioners?
During the process of cooling a portable air conditioner will accumulate moisture and the water needs to be removed from the unit. This condensation can be removed in different ways.
Water tank
This is the most common method and consists of a water tank that is manually removed and emptied. On quality models with a good design, this process is quick and easy. A larger tank will mean less effort.
Automatic Drainage
Some models can be set up to drain automatically. This is convenient as, once set up, there is little to nothing that has to be done when using the air conditioner. It does, however, reduce the portability of the unit.
Connecting the drainage hose is a simple process and does not require advanced DIY skills or special equipment. The main thing you need is an outlet where the drainage pipe can be fed through to a convenient area.
Automatic Evaporation
This technology is found in some of the more advanced models. Water does not condensate so there is no need to dispose of any excess moisture or water accumulation. This makes these models a breeze to operate and maintain.
What is a swamp cooler?
Many people are confused by this term and it might not sound appealing until you understand it. Traditional air conditioners use compressors and refrigerants (gas) to cool the air. Many ventless portable air conditioners use an evaporative process to reduce the air temperature.
They use a fan to draw in the old warm air and run it over cooling pads that are wet. This process cools the air for a more comfortable environment. Many also have filters to reduce impurities in the air. This cooling system requires a fresh source of air so ventilation is necessary.
How do I maintain my ventless portable air conditioner?
Fortunately, little to no maintenance is required. Apart from emptying the water tank, the only important thing to do often is to keep the unit clean.
Keep the housing clean at all times by using a damp cloth. Clean the evaporative elements with lukewarm soapy water monthly. If there is a build-up of mildew it should be sprayed with a disinfectant.
When the cooler months return it is important that you store the unit correctly. Drain the water tank and all lines and give it a good clean. Ensure that it is dry and cover it before storing it in a safe dry area.
Can a ventless portable air conditioner be used in a server room?
This is a common question as these spaces require low temperatures. A quality model will be safe and effective in maintaining a low temperature in any server room.
Are ventless portable air conditioners expensive to run?
One of the many advantages of these options is that they do not use gas and compressors like traditional fixed air conditioners This makes them extremely efficient and cost-effective to run.
Can ventless portable air conditioners be used outdoors?
Ventless portable air conditioners, also known as evaporative coolers, are designed primarily for indoor use. While some models may be used in shaded outdoor areas, their effectiveness diminishes in direct sunlight or high humidity conditions. It’s essential to check the manufacturer’s guidelines to determine if a specific model is suitable for outdoor use.Airfrov
How often should I clean and maintain my ventless portable air conditioner?
Regular maintenance is crucial to ensure optimal performance. Typically, you should clean the water tank and cooling pads every two weeks, especially during peak usage. Additionally, check and clean the fan and filters monthly. Always refer to the user manual for specific maintenance recommendations for your model.
Are there any safety precautions I should take when using a ventless portable air conditioner?
Yes, safety is paramount. Ensure the unit is placed on a stable, flat surface to prevent tipping. Keep the power cord away from water sources to avoid electrical hazards. Never operate the unit without water in the tank, as this can damage the motor. Always follow the manufacturer’s safety instructions provided in the user manual.
