Can I Run My Evaporative Cooler All Day?


An evaporative cooler, commonly referred to as a swamp cooler, is an alternative to conventional air conditioning systems that is both more affordable and less harmful to the environment. It works by bringing hot air from outside into the room and then passing that air over pads that have been moistened with water. This process both cools and humidifies the air before it is circulated back into the room.

If you are thinking about purchasing an evaporative cooler but live in a dry, hot area, you may be curious as to whether or not you can leave it on all day. The solution is not easy to come up with and is contingent on a number of different circumstances. In this post, we will explore the advantages and disadvantages of leaving an evaporative cooler running continuously throughout the day, and we will present some suggestions to assist you in making a decision that is based on accurate information.

Benefits of Running an Evaporative Cooler All Day

Energy Efficiency

Evaporative coolers save a significant amount of energy, which is one of their primary advantages. Evaporative coolers, in contrast to conventional air conditioners, which rely on refrigerants in order to cool the air, just require electricity in order to power the fan and water pump. Because of this, they have a far lower energy requirement and cost significantly less to run than conventional air conditioners.

Environmentally Friendly

Evaporative coolers offer a number of benefits, one of which is that they are kind to the natural environment. They do not give off any dangerous chemicals or glasshouse gases, thus they do not contribute in any way to the warming of the planet. Your carbon footprint can be reduced and the environment can be preserved for future generations if you run an evaporative cooler continuously throughout the day.

Comfortable Indoor Climate

If you live in a hot and dry region, keeping an evaporative cooler running all day can help keep the temperature inside your home at a tolerable level. You may minimise the discomfort produced by high temperatures and low humidity levels by maintaining a constant circulation of cold, humidified air in your space. This will allow you to remain comfortable.

Drawbacks of Running an Evaporative Cooler All Day

Increased Maintenance

When an evaporative cooler is used continuously throughout the day, one of the most significant negatives is that it may require more frequent maintenance checks. In order to prevent the growth of mould, germs, and any other potentially hazardous substances, the water pads will need to be cleaned on a regular basis. Running the refrigerator all day can also cause the water pads to wear out more quickly, which means they will need to be replaced more frequently.

Increased Water Usage

Running an evaporative cooler continuously throughout the day can lead to an increase in water consumption, which is another disadvantage of doing so. The water reservoir in the cooler needs to be kept full in order for it to perform properly; if it is left on all day, it will use up more water. Those who live in regions that have water limitations or who are making an effort to save water may find this to be a source of concern.

Limited Cooling Effectiveness

Last but not least, it’s essential to keep in mind that typical air conditioners are far superior to evaporative coolers when it comes to efficiently cooling off large rooms. It may be difficult for them to cool bigger areas, particularly if the relative humidity is high, hence they are most effective in cooling spaces that are small to medium in size. Even if you leave the refrigerator running all day, you might not get the desired cooling effect, especially if the weather is humid.

Guidelines for Running an Evaporative Cooler All Day

Regular Maintenance

It is imperative that you perform routine maintenance on your evaporative cooler in order to ensure that it continues to function properly if you choose to leave it on all day. The water pads need to be cleaned, the water level needs to be checked, and the fan and pump need to be checked to make sure they are operating correctly. In addition to preventing potential issues and extending the life of the cooler, routine maintenance will help the device last longer.

Monitor Humidity Levels

When operating an evaporative cooler throughout the day at home, it is essential to keep a close eye on the relative humidity of the air. Uncomfortable conditions can be caused by high levels of humidity, which can also promote the growth of mould and bacteria. You may monitor the humidity levels in your home with a hygrometer and then change the temperature of the cooler to match the readings. For JB quality air conditioning range see here.

Consider Room Size and Climate Conditions

When deciding whether or not to let your evaporative cooler run continuously throughout the day, it is essential to take into account the dimensions of the space you wish to cool as well as the weather patterns prevalent in your region. As was noted, evaporative coolers are most effective in cooling places of a size range between small and medium, and they may have difficulty cooling bigger areas, particularly when the air is humid. If you live in a dry, hot region, leaving the air conditioner on all day may be more efficient at keeping you cool than leaving it on in a climate with high humidity.


In conclusion, leaving an evaporative cooler on all day might result in both positive and negative outcomes for the household. It is possible for it to be energy-efficient and favourable to the environment, but it can also result in an increase in the amount of water used and the frequency of maintenance that is required. Before you make the decision to leave your evaporative cooler on all day, you should first consider the dimensions of the space that needs to be cooled, the weather patterns that prevail in your region, and the relative humidity of the air inside your home. Maintaining the cooler on a regular basis and keeping an eye on the relative humidity can also be helpful in ensuring that it operates successfully and efficiently.
