How cold do swamp coolers get?

A swamp cooler operating at 85 percent efficiency can bring the temperature down to a nice, cool 72.3 degrees Fahrenheit (22.3 degrees Celsius), right in the human comfort zone.

How many degrees does a swamp cooler cool?

Here's the deal: your swamp cooler will only cool your home by about 10 degrees. In addition, it will struggle immensely, and likely will not work at all, when its humid outside. If you're new to New Mexico and swamp coolers, you might be new to monsoon season, the time of year a swamp cooler is simply not an option.

Does a swamp cooler actually cool?

According to the US Department of Energy (DOE), an evaporative cooler can successfully reduce the ambient temperature by 5 to 15 degrees—but even the DOE is quick to clarify that this process works only in areas with low humidity.

How many windows should you open for a swamp cooler?

Open the windows or vents on the leeward side of the house to provide 1 to 2 square feet of opening for each 1,000 cfm of cooling capacity. Experiment to find the right windows to open and the correct amount to open them. If the windows are open too far, too much hot air will enter.

Do swamp coolers use a lot of electricity?

Another consideration will be energy efficiency. Overall swamp coolers have been found to be far more energy efficient for home cooling. Swamp coolers will use 15% to 35% of the energy that most traditional AC units would use. They also do not require any chemicals in the way that traditional AC does.

How to make your swamp cooler even colder

Does swamp cooler work in 110 degrees?

Evaporative coolers are limited in that they can only lower the temperature a few degrees below the ambient temperature of the room. If it's 110 degrees outside, you need to lower the temperature inside by more than a few degrees.

At what temp does a swamp cooler stop working?

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.

At what dew point do swamp coolers stop working?

If you want to gauge a cooler's efficiency in terms of dew point, just keep in mind that, in general, a dew point in excess of 55 is generally a swamp cooler humidity limit.

Will a swamp cooler work in Florida?

Evaporative coolers (also known as swamp coolers) can be used in any climate because no place has 100 percent humidity. The process of using an evaporative cooler does add more humidity to the air, which is not something you would want during the summer in a humid location like Florida.

How much does it cost to run a swamp cooler all day?

How much does it cost to run a swamp cooler all day? Swamp coolers will cost about $2 to run for 24 hours. To run a unit 24 hours a day, every day, for an entire month, it would cost roughly $60. In comparison, a central AC costs about $330 per month at this rate.

What humidity is too high for a swamp cooler?

Swamp coolers work in humidity up to about 70 percent. However, you may begin to feel muggy before the air reaches this saturation with or without a swamp cooler.

Can you run a swamp cooler 24 7?

A swamp cooler can be in operation for 24 hours of the day, but you will need to ensure it has enough water. Continuous flow coolers will automatically work and will be fine to run all day. Manual swamp coolers require you to add water to the reservoir and change the settings so it will run all day efficiently.

Which is better swamp cooler or air conditioner?

air conditioner battle winner is the air cooler in a dry climate! Swamp coolers will only add to that if your area is constantly humid over 50% of the time. However, if you live in a dry or normal climate, they can effectively cool down, humidify, and purify the air.

Do swamp coolers work in dry heat?

Because of the way in which swamp coolers cool the air, they are most effective in very dry climates and don't perform as reliably in higher humidity.

Do swamp coolers work in Arizona?

In Arizona during the spring and fall, it isn't quite hot enough yet to justify turning on the central AC. These seasons are the perfect times to rely on a swamp cooler. Evaporative cooling will also add moisture to the air, which helps make the home more comfortable during these times of year.

Do swamp coolers work in the desert?

Swamp coolers are an excellent low-cost way to supplement traditional air conditioning. They work well in our desert climate and use much less electricity than an air conditioner. Ideally, they work best when the temperature is less than 100℉ (38℃) and less than 27% humidity.

Can you run AC and swamp cooler at the same time?

Running the evaporative cooler and air conditioner at exactly the same time would be a bad idea. Evaporative coolers need air flow, and air conditioners need a closed area. Evaporative coolers add moisture to the air, while air conditioners remove moisture from the air.

Why are swamp coolers on the roof?

Evaporative coolers work basically the same way: Hot air enters the outdoor unit, usually housed on the roof. Water-filled pads at the bottom of the unit cool the hot air. The cool air circulates through ducts and then leaves the house via return vents and windows.

Is it cheaper to run a swamp cooler or AC?

In general, swamp coolers do cost less to run that conventional central AC.

What are the drawbacks of evaporative cooling?

Because it adds humidity to the air, running your evaporative cooler constantly can cause your home feel sticky and less comfortable, rather than improving comfort. Additionally, evaporative coolers require a steady supply of water to maintain adequate cooling.

How much water does a swamp cooler use a day?

At seven gallons per hour for 24 hours, the cooler would use 168 gallons of water per day. Some people do decide to run their evaporative coolers around the clock, but it is likely that you will not need to run it for 24 hours every day.

How long does a swamp cooler last?

But, while swamp coolers don't cost much to buy, they are a lot of work and money to maintain. Not only that, they are only warrantied to work for 5 years. Refrigerated air systems can last up to 20 years if properly maintained.

What happens if you run swamp cooler without water?

A swamp cooler will still operate without water flowing to it, but this means it will run without lubrication, in turn causing irreversible damage to the pump from the friction.

Do swamp coolers work in 50% humidity?

Evaporative coolers are efficient for cooling spaces with low relative humidity. The level of relative humidity in your home should stay between 30 and 50 percent for optimum efficiency of your unit. You can still operate an evaporative cooler at humidity percentages up to 60 percent or more.

Can you use a dehumidifier with a swamp cooler?

In short, you can use dehumidifier with swamp cooler to reduce humidity and improve cooling. However, the compatibility of both appliances is dependent on various factors, especially humidity and size of dehumidifier. If humidity is very high, then swamp cooler will not be able to function properly.
