Swamp coolers work on evaporation the water flowing over the plates causes the cooler and more humid air then the blower pushes this into the home. Folks may think the fan on the furnace air handler can’t be run because you don’t heat and cool at the same time.

Can I run a swamp cooler and AC at the same time?

If you have both an evaporative cooler and central air unit, do not run them at the same time. Doing so would cause the two systems to work against each other. If you have central air, there is no need to crack a window or open a door to make the system more effective.

Is it OK to run a swamp cooler all day?





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.

Do swamp coolers work in high heat?

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.

When should you not use a swamp cooler?

They have a hard time cooling your home when it gets above 95 degrees. 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.

Should you use ceiling fans with swamp cooler?

Absolutely! For light cooling, or just to move cooler air throughout your home, fans will work best. It is only once temperatures reach turn warm that swamp coolers do their best work. One way to improve energy efficiency when using swamp coolers is to wait until the temperatures reach 85 degrees.

How cold can a swamp cooler get a house?





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 windows should be open with a swamp cooler?

You should have 1 to 2 square feet of a window or open door space for every 1,000 cubic feet per minute (CFM). For example, you have a 4,000 CFM system and windows with 4 square feet of space to the outside when opened. You need 4-8 square feet of space, which is 1-2 windows open, to run this system.

Does putting ice in a swamp cooler help?

Putting ice in your swamp cooler will reduce the effectiveness of the evaporative cooling process. Water needs to hot in order to evaporate, so adding ice increases the time it takes for the cooler to effectively cool the space.

At what humidity level do swamp coolers stop working?

In Closing



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. In order to do this, you will want to employ strategies to increase airflow.

Can a swamp cooler damage electronics?

Swamp cooler can affect functioning and potentially harm electronics, when it increases relative humidity to levels causing condensation.

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.

How much electricity does a swamp cooler use?

The study showed that the typical evaporative cooler consumed about 1500 kilowatt-hours of electricity per summer, costing about $150 at current rates. The cooler’s water consumption added an average of $54 to a municipal water bill over the course of the summer, for an electricity-and-water total of $204 per year.

Does evaporative cooling work at night?



Using Evaporative Air Conditioning in a Heatwave

You can keep it running 24/7 until the hot spell ends. You can turn the aircon on to fan only over night if the night temperatures are in the mid 20s or keep it running over night if the temperature are close to 30 degrees.

Does ice in a swamp cooler work?

Ultimately, it is up to you whether you put ice in your evaporative cooler. Most likely it won’t hurt anything – we say most likely because theoretically your pump could suck up a piece and seize up. You just have to weigh if you think it is worth a 2°F temperature difference over a 30-minute time period.
