Can you control temperature with evaporative cooler?

You have to pay attention to the temperature, monitor the fan speed and open and close windows. Basically, you’re the thermostat. It doesn’t have to be this way! You can control the temperature in your home by installing a digital swamp cooler thermostat.

Is evaporative cooling more efficient?

While fixed evaporative cooling systems can be a bit more expensive to install (most portable evaporative coolers are ready to use out of the box), operation costs are minimal – often as low as a $1 a day – making them much more energy efficient than air conditioning.

At what temperature do evaporative coolers become ineffective?

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.

How do I make my evaporative cooler colder?

Can you use an evaporative cooler and dehumidifier together?

Paired up, a dehumidifier can significantly improve the cooling efficiency of a swamp cooler on a humid day or inside a sealed house. For best results, point the dehumidifier vent at the swamp cooler intakes so that the driest air is being used to create more lovely coolness.

Does an evaporative cooler need to be vented?

Evaporative coolers don’t require venting like portable ACs, but the air forced out will still require an exit path in order to ensure sufficient cooling (this can usually be accomplished with an open door or window).

Do you keep windows open with evaporative cooling?

To get the most of the evaporative cooling system, it is important to leave your windows partially open as it allows warm air to escape as it is being replaced by cooler air. As evaporative air conditioners use air from outside to recirculate into the house, your house is filled with fresher, cleaner air.

How many windows should be open for evaporative cooling?

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.

Why is my evaporative cooler not blowing cold air?

Probably the single most common reason your swamp cooler is not blowing cold air is that the circuit breaker has tripped or the fuse has blown. These are installed so as to avoid electrical damage to the unit, so it doesn’t get fried in the case of an electrical overload.

Can you leave evaporative cooling on overnight?

Yes, it is possible to leave an evaporative cooler on overnight. It is common for some people to leave the cooler on continuously for a 24-hour period. There is no issue with the system running continuously, but you may wish to consider leaving it on overnight if you live in a humid climate.

What are the drawbacks of evaporative cooling?


  • does not perform well in humid climates or during rainy periods.
  • temperature control is limited.
  • basic air filter system only, many airborne irritants or odours missed.
  • not ideal for those with asthma or respiratory issues.
  • can use up to 25 litres of water* an hour depending on the fan speed and humidity.

Why are my floors wet with evaporative cooling?

If you are experiencing a lot of moisture on your flooring while your evaporative air conditioner is running, there is likely not enough windows open to allow proper air movement. This is a crucial element in the process of evaporative air conditioners, as you’ll need to encourage the airflow.

What is better evaporative cooler or air conditioner?

The upside is the AC units are powerful enough to cool an entire house or a large indoor area. Evaporative coolers have much lower emissions than AC units. They also cause far less noise pollution than traditional air conditioning units, if that is a concern in your area.

Where do evaporative coolers work best?

Evaporative cooling works well in hot and dry climates where humidity is typically below 25% on hot summer days. Evaporative coolers will operate under higher humidity conditions, particularly when the ambient temperature is cooler, however increased airflow is often required to achieve satisfactory cooling.

What is the major advantage of an evaporative cooler?

Evaporative cooling advantages:
Evaporative coolers are less expensive to install, estimated at about half the cost of refrigerated air conditioning. Operation costs are less, as well. Power consumption, limited only to the fan and water pump, is estimated at one-fourth that of air conditioning.
