Why is my house so hot with a swamp cooler? If your house feels hot with a swamp cooler, it might be due to factors like inadequate airflow or incorrect sizing for the space.

Do you have to open a window when using a swamp cooler? Yes, opening windows slightly allows for proper air circulation and helps the swamp cooler work effectively.

Is it OK to run a swamp cooler all day? Yes, it's generally fine to run a swamp cooler all day, especially in hot and dry climates.

How many square feet will a swamp cooler cool? The cooling capacity depends on the swamp cooler's CFM and the climate. A properly sized cooler can cool hundreds to thousands of square feet.

Will a swamp cooler work in Florida? Swamp coolers are less effective in Florida's humid climate; traditional AC is usually a better choice there.

Do swamp coolers work in 30% humidity? Yes, swamp coolers work well in 30% humidity, and this level is conducive to efficient operation.

What makes a swamp cooler colder? Swamp coolers cool air by evaporating water, which lowers the temperature through the process of evaporative cooling.

Do swamp coolers work as well as AC? Swamp coolers are effective in dry climates but are generally not as efficient as air conditioning in hot and humid environments.

Should I use a ceiling fan with a swamp cooler? Using a ceiling fan in conjunction with a swamp cooler can enhance air circulation and improve cooling efficiency.

Does my CFM have to match the square footage? Matching CFM to square footage helps ensure effective cooling, but other factors like climate and humidity also play a role.

How many square feet is 50 CFM good for? 50 CFM would be suitable for a very small area, perhaps a bathroom or a tiny corner.

What is the rule of thumb for CFM per square foot? A common rule of thumb is around 1 CFM per square foot of space for efficient cooling, but it can vary based on climate.

What is the thumb rule for air conditioning? A general rule is to set the thermostat to 78-80 degrees Fahrenheit for energy-efficient air conditioning.

How humid is too humid for a swamp cooler? Swamp coolers become less effective as humidity levels approach or exceed 60%.

Why don't swamp coolers work when it's humid? Swamp coolers rely on the evaporation of water to cool air. In humid conditions, the air is already saturated with moisture, so less evaporation occurs.
