If you have an evaporative cooler, you know how great they are at keeping your home cool and comfortable during the hot summer months without the expense of air conditioners. But what do you do when your evaporative cooler stops blowing cold air?
There are a few common reasons why an evaporative cooler might stop blowing cool air but don’t worry, in most cases, you can fix the problem yourself. In this blog post, we’ll go over some of the most common reasons why an evaporative cooler stops blowing cold air, as well as some tips on how to get your swamp cooler blowing cold air again.
How Air Coolers Work
Air coolers work by evaporating water to cool the air. The evaporative process happens when the air temperature is lower than the dew point, or when the relative humidity is high. The water evaporates, drawing heat from the air and cooling it.
The air cooler has a water reservoir that needs to be refilled periodically. A pump circulates water from the reservoir to the pads. As the water evaporates, it cools the air that is pulled through the pads by the fan.
There are four main parts to an air cooler: the water reservoir, the pump, the pads, and the fan. The water reservoir needs to be refilled periodically, and the pump circulates water from the reservoir to the pads. The pads are soaked with water, and as the water evaporates, it cools the air that is pulled through the pads by the fan.
The air cooler is not as effective in humid conditions because the air is already saturated with water vapor. The air cooler is also not as effective in very dry conditions because there is not enough moisture in the air to evaporate.
Common Reasons Why an Evaporative Cooler Stops Blowing Cold Air
There are a few reasons why your evaporative cooler may have stopped producing cool air. The most common reasons are a dirty cooler rotor, a fan that needs to be replaced, or dirty filters.
Check the Fan motor
An evaporative cooler, also known as a swamp cooler, uses the natural process of evaporation to cool the air. As water evaporates, it absorbs heat from the air around it, lowering the air temperature.
The fan motor is one of the most important parts of an evaporative cooler, as it is responsible for circulating the air. If the motor is not working properly, the air will not be circulated and the evaporative cooler will not be able to function.
There are a few reasons why the motor might not be working properly. One possibility is that the motor is not getting enough power. Another possibility is that the motor is defective. If you think that the problem is with the fan, the first thing you should do is check the power supply. Make sure that the power cord is plugged in and that the circuit breaker is not tripped. If the power supply is not the problem, you will need to replace the motor.
Dirty air filters are one of the most common reasons for an evaporative cooler to stop blowing cold air. When the air filter is clogged with dirt and dust, it restricts airflow and prevents the evaporative cooler from working properly.
To clean the clogged air filters, first, turn off the power to the unit. Then, remove the air filter and rinse it with water. Let the air filter dry completely before putting it back in the unit. If the filters are extremely dirty, you may need to replace them. To do this, consult your owner’s manual for the correct replacement filter size. Once you’ve replaced or cleaned the filters, turn on the power to the unit and check to see if the cold air is flowing properly.
Clogged condenser coils
There are several reasons why your evaporative cooler might stop blowing cool air, but one of the most common is a clogged condenser. A clogged condenser can cause the unit to overheat and shut down, preventing it from cooling the air.
To clean your condenser, you’ll need to remove the unit’s housing and access the coils. Use a brush or compressed air to remove any dust or debris that might be clogging the coils. Once the coils are clean, place the housing and turn on the unit. If it still isn’t working, you may need to call a technician.
Unit is Too Small
If your cooler is too small for the space, it won’t be able to circulate the air properly and will struggle to keep the space cool. On the other hand, if your cooler is too large for the space, it will cool the air too quickly and won’t be able to maintain a consistent temperature.
The best way to ensure you have the right size evaporative cooler is to have a professional come and assess the space you’re trying to cool. They will be able to recommend the perfect size unit for your needs.
If you’ve already purchased an evaporative cooler and it’s not the right size, you can try to return it or exchange it for the right size. However, many retailers have a policy that all sales are final on evaporative coolers, so you may not be able to return them. In this case, you’ll either need to sell it and buy the right size unit or find a way to make it work in the space you have.
One of the most common reasons why an evaporative cooler stops blowing cool air is improper installation. If the cooler is not installed properly, it will not be able to function properly and will not be able to cool the air effectively. There are a few things that you need to do to make sure that your cooler is installed properly:
1. Make sure that the cooler is level. If the cooler is not level, the water will not be able to flow properly and the air will not be cooled effectively.
2. Make sure that the cooler is not too close to the ground. If the cooler is too close to the ground, the air will not be able to circulate properly and the air will not be cooled effectively.
3. Make sure that the cooler is not too close to the wall. If the cooler is too close to the wall, the air will not be able to circulate properly and the air will not be cooled effectively.
4. Make sure that the cooler is not in an area where there is a lot of dust or near a window. If the cooler is in an area where there is a lot of dust, the air will not be able to circulate properly and the air will not be cooled effectively.
Air coolers are a great way to keep your home cool, but if they stop blowing cool air, it can be a frustrating experience. There are a few common reasons why this happens, but fortunately, there are also a few things you can do to get your cooler blowing cool air again. By following these tips, you can enjoy the cool air your swamp cooler provides once again.
