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.
Can a swamp cooler cool an entire house?
MasterCool 7000 CFM 115V 2 Speed Down Draft 12″ Media Evaporative Cooler. This powerful evaporative cooler can cool up to 2,200 square feet of living space. Like all whole-house swamp coolers, the MasterCool 7000 CFM is hooked up to a continuous water source to maintain water levels.
At what temperature does a swamp cooler become ineffective?
According to USA Today, “When the outside temperature soars to 100 degrees (38 C), we’re in trouble if the humidity is much above 25%.” As temperatures rise, humidity must decline in order to effectively cool your home.
How much can a swamp cooler cool a house?
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.
What are the disadvantages of swamp cooler?
Cons: Swamp Coolers Don’t Work Well Over 35% Humidity – On those days when the humidity rises, a swamp cooler has a harder time cooling your home. Since water evaporation is the core of the cooling process, the air that is already saturated with water (humid air) is difficult to cool.
Can I leave my swamp cooler on 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.
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.
Should you open windows with a swamp cooler?
Open windows let out hot air when you’re using a swamp cooler. Air conditioning cools and recirculates air in a room or in an entire building. It is essential to keep the windows closed so the cooled air does not escape.
Why are swamp coolers on the roof?
Swamp coolers require winterization to prevent system damage, taking them out of commission for months out of the year. Many swamp coolers are installed on the rooftops of homes in Colorado. They also need to be winterized in order to prevent water transmission lines from bursting when below-freezing temperatures hit.
What is better swamp cooler or AC?
For budget savvy consumers, the swamp cooler is the more economical choice for summer cooling. Central AC does require some maintenance, but this is mostly clearing away debris from the compressor and making sure that the air filters are changed. Evaporative coolers require much more maintenance.
How long do swamp coolers 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.
How much electricity does a swamp cooler use?
The swamp cooler requires far less electricity thereby saving money. For example, if electricity costs $0.15 per Kwh (Kilowatts per hour), it takes $1.13 per hour to operate an A/C system. It’s only $0.26 per hour to run the cooler.
Where do swamp coolers work best?
Swamp coolers work best in very hot and dry climates, such as those found in the desert regions. This is because they add moisture to the air. In a humid climate, a swamp cooler could lead to excess humidity, along with mold and mildew growth.
How often should swamp cooler pads be changed?
Cleaning your pads annually helps manage mineral buildup, makes the pads last longer, removes foreign matter (like cottonwood seeds) and improves efficiency. For Mastercool swamp coolers, you should clean the pads annually and replace them every 3-5 years.
Are swamp coolers unhealthy?
Swamp coolers do have the potential to harbor mold and mildew. The pads do stay wet through the season, which means that mold could grow. Some people may experience difficulty breathing if your evaporative unit gets mold. To prevent mold growth, you need to keep the moisture level under control.
Can you use swamp coolers indoors?
Most effective in dry climates where humidity is 60% or below, they move air over a moisturized cooling pad that can reduce your room temperature up to 20 degrees. Our customers commonly use them in bedrooms, living rooms, garages, commercial indoor areas, and outdoor spaces like pool decks.
Do swamp coolers work at night?
Evening hours are a great time to run the swamp cooler. You can optimize airflow for dinner-time comfort and relief.
Does ice in a swamp cooler work?
In actual practice, adding ice to your swamp cooler only has a limited effect. It’s the combination of temperature and humidity in the ambient air that determines how much of a boost ice provides, not the ice itself. In fact, adding ice to your evaporative cooler might actually hamper the cooling process.
Are swamp coolers loud?
Evaporative coolers are more economical to run in dry climates than traditional air conditioning systems. While this process uses less energy than air conditioning, it’s still fairly loud. If nothing else, the machine’s motor creates noise when it runs.
