Did you know that a portable AC without window access has other names?
They are evaporative coolers – meaning that they cool the air using evaporation, just like your skin feels cool when the breeze dries water off of it.
Other names are chillers and, our favorite, swamp coolers.
Alternatives for Portable AC Without Window Access
Mini split ductless air conditioning and heat pump systems are the leading alternative to evaporative portable ACs when there is no window.
Yes, they cost more, but they do a very good job cooling. And they are rated for all parts of the country, including very humid regions where evaporative coolers are not effective.
Will Using a Dehumidifier Help Me Run a Swamp Cooler?
No. The electrical use will heat up the unit and make the temperature in the room higher. Plus, the evaporated moisture from the cooler will condense back into water and release the heat it removed.
In short, the two units will work against one another, defeating the purpose of the swamp cooler.
Is there a best ventless air conditioner for a high humid area?
No. ventless air conditioners are not designed for use in areas with high humidity. The physics of evaporation, relative humidity and temperature just won’t work.
FAQs
Does a ventless air conditioner and heater combo exist?
No.
If you need affordable cooling in a dry part of the country plus space heating, then we recommend buying a personal or room ventless AC from the list above and also buy a small space heater.
Will an evaporative cooler / ventless AC work in a basement?
Only if the humidity level is pretty low – below 50% relative humidity, for example. Basements are usually the most humid part of any home.
If you live in a dry part of the country, and your basement isn’t leaky / doesn’t have moisture issues, then an evaporative cooler might work.
How do ventless portable air conditioners operate?
Ventless portable air conditioners use evaporative cooling technology. They draw in warm air, pass it over water-saturated cooling pads, and release cooler air back into the room. This process doesn’t require venting hot air outside.
What should I consider when purchasing a ventless portable air conditioner without a hose?
We recommend evaluating the unit’s cooling capacity, energy efficiency, and noise level. It’s also important to check the room size it can effectively cool and its water tank capacity.
Can ventless portable air conditioners also provide heating?
Some models offer heating functionality, making them versatile year-round appliances. However, not all ventless units include this feature, so it’s essential to check product specifications.
How effective are ductless air conditioners in cooling a space?
Ductless air conditioners can be quite effective, especially in smaller areas. Their performance depends on factors like room size, insulation, and ambient temperature.
What are the pros and cons of portable air conditioners without venting?
Pros include easy installation, portability, and no need for window access. Cons may involve limited cooling capacity and the need for regular water refills.
What are my options for cooling a room without window access?
Ventless portable air conditioners are ideal for rooms without windows. Other options include evaporative coolers, tower fans, and ceiling fans.
