Ductless Mini Split Air Conditioners
Ductless Mini Split Air Conditioners are a two-part system that cools and heats one or more rooms in your home. They have an indoor air handling unit and an outdoor unit with a compressor.
The indoor unit is usually hung on a wall or suspended on a ceiling, and it blows cold air into your space. This unit is connected to the outdoor compressor through a refrigerant line. As such, you don’t need to have ducts in your home to install a mini split system.
You can have one or several indoor units depending on the number of rooms you want to cool. While multiple indoor air handling units are usually connected to one outdoor unit, you can always control them independently.
Advantages of Ductless Air Conditioners
Mini split systems are great choices for homes with no existing ductwork. They are also ideal for apartments where the owners are only looking to cool a certain area at a time. The good thing is each room has its own thermostat, allowing you to condition only rooms that are currently occupied while saving energy in unoccupied zones.
Here are the advantages

Swamp Cooler/ Evaporative Cooler
Evaporating cooling is one of the oldest forms for climate control that still exists today. It’s beneficial to people living in hot dry climates, and may not be beneficial in humid climates.
Evaporative cooler are less expensive to purchase and install. Eco-friendly, easy to maintain and add moisture to the air. It’s their ability to add moisture to the air that makes them the perfect fit for dry climates.
How do swamp coolers work? By circulating water through a cooling pad while drawing air across the surface of the cooling pad. Hot air from a heat pump absorbs the moisture from the pad, reducing the temperature of the air discharged by the unit.
While swamp cooler and air conditioners serve the same purpose of keeping your room cool, they operate differently. Evaporative cooling systems draw warm air from the room they are employed while air conditioners take humidity out of the room. The difference between these two units is the operation costs. The cost of operating swamp coolers is much less compared to traditional air conditioners.

Portable Air Conditioners
Portable air conditioners are one of the affordable, most efficient and cost effective spot cooling solutions for a variety of residential and commercial applications. While the advantages of portable ac are numerous, the main advantage is their ability to provide permanent or temporary cooling to specific rooms within a home.
While it’s not a good idea to use a portable air conditioner in a room without a window, you can always be creative with your installation and vent your portable ac using other methods. One of the alternative ways of venting a portable air conditioning system is through a wall, dryer vent, or drop ceiling.
If you choose to vent a portable ac using the methods I’ve mentioned, make sure the heat is transferred to another room or outside the room. You don’t want the heat reentering the room where the ac is employed. Also, don’t extend the exhaust hose because that would reduce the efficiency of the unit.

You can find a variety of models that would work well in rooms without windows. However, one that has performed well for such a situation is the Honeywell MN10CESWW Portable Conditioner, Dehumidifier & Fan. It provides 10000 BTUs and ideal for rooms between 350 to 450 square feet.
Apart from cooling, this ac has an in-built dehumidifier that removes up to 67.7 pints of moisture from your air per day. Another important feature is the fan-only mode that circulates air in your room, preventing room stuffiness during those days when cooling isn’t necessary.

Unlike most portable ac that have to be drained continuously, Honeywell MN10CESWW has two draining options. The first is the manual system where you’ll have to drain the pan that collects the water inside the unit. The most convenient draining option is the self evaporation feature where the hose continuously drains the excess moisture.
Through the Wall Air Conditioners
Through the wall air conditioners are self contained units that can keep one or two rooms in your home cool and comfortable all year round. While wall air conditioners are similar to window units, the only distinguishing factor is how they are installed. Wall mounted air conditioners are installed by drilling a hole through a wall and using sleeves to give it support. Window air conditioners, on the other hand, are simply installed directly in a window.
Installing a through the wall air conditioner has several benefits. They are less expensive and more efficient than central systems. Because of their sleek design and installation in a wall, they not only save a lot of space but also do not compromise the amount of light or view from the window.
If you decide to choose a wall air conditioner for a room without a window, consider the size of the room and where it will be installed. Choose the appropriate amount of cooling power by taking into account the number of people that will occupy the room, ceiling height and how open the room is to the sun.
Apart from traditional wall mounted air conditioners, you can also install wall mini split systems. These are ductless mini split air conditioners that can be permanently mounted on a wall. The advantage of these units is that you don’t have to buy two seperate devices.

Remember, wall air conditioners are permanently installed through your wall, and it’s only wise to hire a professional to do the job. Improper installation can cause unwanted drafts when the ac is turned on. Also, make sure the unit is maintained properly. Schedule for maintenance service, including changing the filter to increase the lifespan of the unit.
