I understand the frustration of having a dehumidifier that is blowing hot air when you are expecting cold, refreshing air. As the old saying goes, “you can’t get something for nothing” and this rings true with dehumidifiers as well. If your dehumidifier is no longer able to cool the air, it may be time for some maintenance and repair.
Why is my dehumidifier blowing hot air? These include high ambient temperature, blocked airflow, dirty evaporator coils, leaking refrigerant, and more to fix it you just have to do some inspection of your dehumidifier.
In this blog post, I will discuss why your dehumidifier could be blowing hot air and how you can fix the issue. With a little bit of understanding and effort, you can get that cool air back in no time!
Why is my dehumidifier blowing hot air?
It can be confusing when your dehumidifier starts to blow hot air instead of cool air. This could mean many things, but it could also just be an issue with the fan motor or the compressor not working correctly.
- Evaporator coil is dirty
- Room is too warm
- Compressor issue
- Controlling Humidity Levels
- Blocked Airflow
- Thermal Overload
- Defrosting Mode
Evaporator coil is dirty:
when the coil gets dirty, it restricts airflow and does not allow cool air from outside to move through and cool down the interior components of your dehumidifier. So, instead of getting chilled air, you get hot.
To resolve this issue, you can either clean the evaporator coil yourself or contact a professional to help. Cleaning it will ensure your dehumidifier continues to blow cool air and perform at its highest level.
When the temperature in the room where your dehumidifier is located gets too cold, then it might enter into defrosting mode to protect itself from damage. During this time, it will stop cooling and start blowing out hot air to help melt any ice that may have built up inside of the unit.
Once the defrosting process is complete and your dehumidifier is able to start cooling again, then it should start blowing out cold air once more. If not, you can try resetting the unit or checking for any issues with its compressor or fan motor.
Room is too warm
When the air in your room is too warm, the dehumidifier can struggle to cool down the interior components. And if the internal parts get too hot, the dehumidifier won’t be able to cool them down enough and will start blowing hot air instead of cold.
To fix this issue, you can try lowering the temperature in the room. This will help the dehumidifier to cool down the interior components and start blowing cooler air again.
Yes, if there is an issue with the dehumidifier’s compressor, it can cause your dehumidifier to blow hot air instead of cool. This could be due to a mechanical issue like a worn or damaged part, or it could be caused by something as simple as a blocked airflow.
To determine the cause of this issue, you should check your dehumidifier for any signs of damage, as well as look into the controls and settings to ensure everything is working correctly. If you are still having issues, it may be best to contact a professional to take a look at your unit.
Controlling Humidity Levels:
Controlling humidity levels is one of the main jobs of a dehumidifier, and when it’s not able to do that job properly, it can start blowing hot air. This could be due to several factors, such as the air in your room being too warm or an issue with the dehumidifier’s compressor or fan motor.
It could be due to the evaporator coil becoming dirty or blocking airflow. Taking a look at all of these potential issues can help you pinpoint why your dehumidifier is blowing hot air so that you can fix the issue and get back to enjoying cool, comfortable air in your home again.
The air that your dehumidifier needs to cool down its interior components comes from outside, and if the airflow is blocked or restricted in any way, then the dehumidifier will struggle to get enough of this cool air. When this happens, it can cause the internal parts to become overheated, resulting in hot air instead of cold being blown out.
To fix this issue, you need to remove any obstructions and make sure that the room where your dehumidifier is located has adequate air circulation. This will allow it to get enough cool air from outside so that it can cool down its interior components properly and start blowing out cold air again.
Sometimes, the interior components of a dehumidifier can become overheated due to a thermal overload, and this can cause it to start blowing hot air. To fix this issue, you should check your unit for any signs of damage or wear and tear that could be causing the problem.
How to stop your dehumidifier from blowing hot air:
No one likes the feeling of hot, stuffy air in their home. A dehumidifier can be a great way to reduce humidity and make your home comfortable. However, it can be unpleasant when a dehumidifier starts blowing hot air instead of cool and refreshing air. Fortunately, there are several steps that you can take to troubleshoot and solve the problem.
- Clean your dehumidifier’s air filter
- Clean your dehumidifier’s evaporator coil
- Thaw out your dehumidifier
Clean your dehumidifier’s air filter:
A dehumidifier’s air filter helps to trap dust, pollen, and other airborne particles that can make your home feel stuffy and uncomfortable. If the filter becomes clogged with debris, it won’t be able to do its job effectively, resulting in hot air being blown out of the unit instead of a cool and refreshing atmosphere.
To prevent this from happening, you should regularly clean the air filter on your dehumidifier. This will ensure that the air flowing into your home is free from allergens and pollutants while ensuring that your dehumidifier runs optimally.
Clean your dehumidifier’s evaporator coil:
Cleaning the evaporator coil is vital for stopping your dehumidifier from blowing hot air. The evaporator coil works by absorbing moisture from the air and then releasing it as cool air into your home. However, if dirt and debris build up on this coil, it can prevent it from cooling properly.
To clean the evaporator coil on your dehumidifier, you’ll need to take apart the unit and use a soft-bristled brush or vacuum cleaner attachment to remove any dust and debris that may have accumulated on the coil. Once you’ve finished cleaning it off, put everything back together before turning your dehumidifier back on.
Thaw out your dehumidifier:
Thawing out your dehumidifier is an important step to take if you find that it’s blowing hot air instead of cool, refreshing air. While this isn’t a permanent solution, it can help in the short term until you can address any underlying issues with your dehumidifier.
During cold weather, ice can form on the coils inside your dehumidifier and cause it to start blowing warm air. To thaw out your unit, unplug the power cord and locate the drain plug or valve at the bottom of the appliance.
Ensure this plug or valve is open so that any melting water can flow freely. Then leave the appliance off for a few hours while the ice melts. After the appliance has had enough time to thaw out, you can plug it back in and turn it on again.
What temperature should the air that your dehumidifier is producing be?
The temperature of air coming out of your dehumidifier depend on the model and the ambient room temperature. Generally speaking, a compressor dehumidifier produces air a few degrees warmer than the air in your room, usually ranging from 3-5°F above room temperature.
On the other hand, a desiccant dehumidifier puts out much warmer air compared to room temperature, with an average difference of 18-22°F.
This slight increase in temperature can make all the difference when it comes to efficiently removing moisture from the environment and providing you with a comfortable living space. Warm air holds more humidity than colder air, so this slight temperature increase helps maximise your dehumidifier’s effectiveness.
If your dehumidifier is blowing hot air, you’ll want to take action and get it back to producing a fantastic, comfortable atmosphere. To do this, check for any issues with the compressor and ensure that refrigerant levels are balanced.
Consider switching to an air conditioner rather than a dehumidifier if you need additional cooling without extra heat. With the right approach, you can enjoy fresh, dry air in all seasons without compromising comfort or energy efficiency. So don’t delay – tackle those warm blasts of air head-on today!
Dehumidifier makes room hot?
It is a common misconception that dehumidifiers can make a room hotter. In fact, dehumidifiers work to remove moisture from the air in order to reduce humidity levels. By doing this, they actually help lower the temperature of a room and create a more comfortable atmosphere.
Do all dehumidifiers blow hot air?
No, not all dehumidifiers produce hot air. Many use refrigeration technology to cool incoming air and remove moisture from it in the process. Some units may blow warm air as a byproduct of this process, but they are generally equipped with a fan that dissipates the heat quickly and keeps the room temperature comfortable. Depending on the type of unit you have.
Does dehumidifier help with AC?
Yes, a dehumidifier can help with air conditioning. When a room is too humid, it can become very uncomfortable and the AC unit may not be able to keep up with the demands of cooling the environment.
