In fact, a swamp cooler is highly effective at cooling and can drop the air temperature by up to 30° F. It can easily take the temperature down from more than 90° F to a comfortable 75° F or lower. Fans, on the other hand, can't cool the air at all and are only useful if you have access to a reservoir of cool air.
If you're truly looking to cool the air to provide a more comfortable ambient temperature, there is no comparison. Swamp coolers are by far the more effective option. Fans use blades to circulate the air in the room.
Drawbacks Due To High Humidity
Although low humidity can affect your health, excessive use of an evaporative cooler result in moisture buildup, promoting the growth of mould, dust mites, and mildew in a confined space.
Swamp coolers are still a great method to augment regular air conditioning at a minimal cost. They perform admirably in our arid heat and consume significantly less energy than that an air conditioning system. They operate better when the heat is far less than 100°F (38°C) and the moisture is less than around 27%.
Evaporative coolers cost about half as much to install as central air conditioners and use about one-quarter as much energy. However, they require a supply of water and need more frequent maintenance than refrigerated air conditioners.
Yes, you can leave an evaporative cooler running 24/7. Evaporative coolers rely on low-power fans that can run for long periods of time without an issue. While it's a good idea to switch the system off every now and then, you can use your evaporative cooler during extended stretches of hot weather.
Cost to run and efficiency
Electricity: A swamp cooler uses 60% to 80% less electricity than a standard AC unit, meaning big savings on electricity costs.
A wet bulb temperature above 70 degrees Fahrenheit (21 degrees Celsius) means the swamp cooler won't be able to adjust the temperature enough to keep it in the comfort zone. (This varies based on humidity, personal preference and activity, but it generally falls in the low 70s.)
'If you're looking for relief from the heat, it's best to put ice in front of a fan, not behind it,' he says. 'When this happens, the cold air from outside will enter through the open window, causing air pressure that pushes hot air out of your house naturally.
How much space a swamp cooler can cool depends on how much air the cooler can move. In general, assume that a swamp cooler can cool one square foot of area for each four cubic feet of air it moves per minute.
The average life expectancy of a swamp cooler is 15 to 20 years depending on how well it has been maintained and the quality of your water. Very hard water will calcify the components of the swamp cooler making it wear out faster.
But worse, breathe bad air in constantly and it can eventually lead to respiratory problems like allergies or asthma. Another problem with swamp coolers as it relates to cleanliness is that moisture in the ductwork causes it to break down over time, pushing metal particles out of the vents and into your home.

Cooling: Advantage Swamp Cooler
If you are looking to cool down a space to make it more comfortable, a swamp cooler has the advantage. That's because an evaporative cooler will actually cool the air, unlike a fan, which just moves hot air around.
Yes, the fan and pump motors are separate systems. You can run one without the other with no damage to the product. That said, however, you will not receive the same degree of cooling by only running the fan.
Coolers are best suited for areas with low humidity. Consider buying one if you reside in an area with dry weather conditions. On the contrary, a portable air conditioner is best for areas that experience high humidity.
Lay the cloth over the fan. As it blows the air out, it'll circulate through the cloth and the air will feel cooler. Make sure that the cloth cannot get caught on the fan in any way at all––if this is a possibility, don't use this method. Replace the cloth frequently, as they dry out.
The salt will lower the freezing point, causing the ice to melt slower and keeping your drinks colder for longer. You can also use salt to melt ice that has already formed. Simply sprinkle salt on top of the ice and watch as it melts. The salt will disrupt the ice crystals and cause them to melt faster.
A swamp cooler may stop working due to clogged cooling pads, a malfunctioning water pump, or a broken motor or fan. Electrical issues like blown fuses or wiring problems can also disrupt operation.
Use a Dehumidifier
Dehumidifiers draw excess moisture from the air and store it in a tank ready for emptying. A dehumidifier makes the air drier, allowing better evaporation and increasing the efficiency of the swamp cooler. Place the dehumidifier close to the evaporative cooler's intake grill for better results.
One of the primary limitations of swamp coolers is their diminished performance in high-humidity conditions. The cooling process relies on water evaporation, which is less effective when the ambient air already contains a significant amount of moisture.
They should not be used when the climate is humid as they use humidity to cool a home. They do require more maintenance from a traditional central air conditioner. They are prone to leaks due to float problems. If the unit is on your roof, the water that leaks from the air conditioner can stain your roof.
Air coolers are the best choice for those on a budget or living in dry, hot climates. They offer an affordable upfront cost, low energy consumption, and eco-friendly operation, making them ideal for individuals who are conscious of both their finances and the environment.
62 kWh to run (at $0.13 per kWh cost me $0.08 cents per hour to run). So depending on the speed, if I ran the swamp cooler 24 hours per day, my cost would be between $1.08-1.92 per day in electricity. Shifting to air conditioning, if you look at the graph above, you can see spikes in the usage.
