Swamp Coolers, also known as an evaporative cooler, cool the air through water evaporation. This cooling appliance is low maintenance, economical, and eco-friendly to use in your garage in comparison to a typical air conditioner. Plus, they also tend to cost less to buy, and they can cost up to 75% less for daily operation than a typical air conditioner.
How do Swamp Coolers Work?
A swamp cooler can cool the air using evaporating water. This process works by pulling dry air in and moving it over a rigid cooling media or a water-moistened cooling pad, which is where the cool water will evaporate into the air cooling the air internally.
How much lower the temperature gets depends on the current relative humidity and the ambient temperature. When you have a lower humidity that is combined with a high temperature, you will get a higher cooling power. Once the cooled air is released, it is re-circulated back into the environment with the use of an efficient, high-powered fan, which creates a gentle, but cool breeze that lowers the air temperature.
For the best cooling experience, remember that the swamp cooler needs to have constant access to fresh air through an open door or window. If it is in an enclosed space, it won’t cool well. If you don’t have a fresh air supply, you will feel an increase in humidity and the air will begin to feel clammy and damp instead of fresh and cool.
Typically, a swamp cooler will be filled manually with water, similar to a humidifier. You will also find models that come with a direct hose attachment that makes it easier to refill.
How do Swamp Coolers Differ from Air Conditioners?
You will find that different cooling methods work better in different climates. The two basic types of cooling systems that will lower the temperature in your home making it more comfortable are air conditioners and swamp coolers. Both are great systems, but they work in two different ways.
- Cooling Method
Perfect for cooling air in houses located in an area with low humidity, swamp coolers work when air is passed over a wet pad while the water found in the pad evaporates into the air. This cools the air and adds some humidity or moisture at the same time. You need to control the water carefully and constantly add to the unit to guarantee that it works properly. If you live in a high humidity area, this is not the best place to use this appliance.
In comparison, an air conditioner works by condensing and then removing water already found in the air. Next, it uses a chemical that is converted from a gas into a liquid and then, before returning to gas again, the unit will pull the moisture out of the air changing the state of the surrounding air that it cools. The air conditioner then blows this cooled air from the compressor and circulates the warm air back outside. You get more control and precision with an air conditioner over your home’s temperature since you can lower it more. Plus, they’re perfect for those areas that have high humidity levels because they lower the humidity while they cool the air.

Both air conditioners and swamp coolers come with a variety of installation choices that depend on the size and type of unit you buy, and where you are installing it. Portable and window air conditioner units do not need professional installation, but a central A/C unit will need to be installed by a professional. When ductwork is required, you may need to reconfigure or add to the ducts to adapt the unit. While a system without ducts may be used, but you will need to hire an electrician or carpenter when installing the unit.
A direct air, window, or portable swamp cooler does not need professional installation, but they will need to be installed near a hose or water hookup. A whole-house unit will probably need professional installation when installing ducts or placing the unit on your roof and anchoring it into place.
Swamp coolers make your house more comfortable by adding moisture into the air if you live in a dry climate. Keep in mind that a swamp cooler is not the best choice if you live somewhere with humidity levels that are higher since it increases the humidity even more. This can lead to issues with mildew and mold growth.
An air conditioner does the opposite by removing moisture out of the air. If you live in an area with high humidity, an air conditioning unit will make your house more comfortable while also drying it out a little. If you live in an area with humidity that is already low, air conditioning can dry out the air too, which can be problematic for your skin and eyes.
- Energy Efficiency
Of the two, a swamp cooler is a more energy-efficient way to cool your home. Using between 15 and 35 % less electricity than an air conditioner needs, it does not need chemicals to work. A swamp cooler just needs a consistent supply of water. It may inefficient in areas with water restrictions or drought making them less effective than an air conditioner that can work in any weather conditions.
Requiring daily, monthly and annual maintenance, a swamp cooler needs to be filled with water at all times and the pad changed when needed. Air conditioners only require annual maintenance that can include charging with chemicals, filter changes, and cleaning.
- CO2 Emissions
Emitting fewer levels of CO2 emissions and greenhouse gas, swamp coolers only use water to cool the air. In comparison, an air conditioning unit needs a cooling chemical or refrigerant. And as the chemicals are converted to gas or liquid, an air conditioning unit will give off CO2 emission and greenhouse gasses that are bad for the environment.
Why are Swamp Coolers Good Solutions for a Windowless Garage?
An inexpensive way to keep your garage cool, a swamp cooler is typically used in a garage in a less humid and dry climate. These energy-efficient machines cool the air by changing water into vapor. During this process, the energy found in the air doesn’t change and the warm dry air is changed into cool and moist air. Keep in mind that a swamp cooler will need a constant supply of water to maintain the moisture in the system, which should be easy to provide in your garage.
While it is often bulky, a swamp cooler is a pretty solid cooling solution for a typical residential garage. While larger units aren’t difficult to install, swamp coolers are also available in portable units that you can easily move around your garage to cool off different areas as needed.

Considerations When Choosing the Best Swamp Coolers for Garage
- Residential Swamp Coolers
Typically, smaller units that are made for spot cooling, residential swamp coolers usually come with large caster wheels and a carrying handle that makes it easy to move them from room to room. They are a good option if you need a cooler that has the flexibility to move with you.
- Commercial Swamp Coolers
Larger units that can cool a large space, commercial swamp coolers usually come with forceful CFMs and large propellers. They also can include an ALCI feature with a GFCI safety plug built in making them perfect for wet and outdoor conditions.
- Swamp Cooler Sizing
It is important that your swamp cooler is rated for the space you will be using it in. If it’s too small, it won’t cool the room. If it’s too big, it will be overkill. Make sure you check the CFM rating, or cubic feet per minute, which refer to how much air is passing through the cooler each minute. Typically, the higher the CFM rating, the faster the swamp cooler will cool the air making the coverage of your garage better.
- Water Tank Capacity
- 1 to 3-gallon capacity – Small bedrooms, kitchens, sitting rooms, or home offices
- 3 to 7-gallon capacity – Medium rooms like living rooms, sunrooms, or dens
- 7 to -12-gallon capacity – Large rooms like bedrooms, living rooms, garages, or cooling multiple rooms
- 12 to 16-gallon capacity – Patios, pool areas, garages, and large decks
