The RV tends to get warm during the summer months and you will want to prepare for this by assessing the air conditioner in the RV.
If the RV air conditioner is not running smoothly, you are going to end up with an overheated vehicle that is not easy to deal with.
This is a common issue when the RV air conditioner is not blowing hard.
If the RV air conditioner is not blowing hard, start by checking the air filter for debris. Clean out the debris, remove ice from the coils, and replace any damaged coil in the setup.
It is common for air to not get through when the filter is dirty. This is why you are going to want to inspect this before any other part. It is normal for this to happen over time, which is why maintaining the RV air conditioner is a must.
This guide is going to provide steps on what to do if the RV air conditioner is not blowing hard and what will push the air through.

Steps To Follow If The RV Air Conditioner Is Not Blowing Hard
1. Check For Debris On The Filter
When the RV air conditioner is not keeping up, you will have to go to the filter.
This is one of the main issues that crop up as time goes on and you haven’t cleaned the filter. It’s best to have a process in place to inspect the filter before it gets worse.
Otherwise, you are going to have an issue such as this where the RV air conditioner is not blowing air.
When you go to the filter, you will want to look for debris. Is there debris in the filter that is now clogging the airflow?
If yes, this is likely the root cause of what is going on with the RV air conditioner. You will want to get rid of the debris and make sure the filter is clean.
This is the only way you are going to get the air conditioner to work the way you want it to.

2. Remove Any Ice On The Coils
You should also take the time to look at the coils.
This is how you are going to get the air to cool down to the point you want it to. If these are not working, the pressure is going to get impacted to the point it will render the air conditioner useless.
This is why you want to be on top of this part of the RV air conditioner.
Look at the coils to see whether or not ice has built up on them. This ice will need to be removed from the coils to get them back to how they need to be.
3. Check The Coils And Evaporator Temp Sensor For Damage
You will also want to look at the coils to see if they are damaged.
It is common for them to get damaged due to the build-up and that is when you will have to replace them as soon as you can.
Another part that people overlook is the evaporator temperature sensor. This part can come loose and that will also cause the airflow to get obstructed.
You will want to take the time to put the evaporator temp sensor back where it needs to be. This is going to make it easier for you to focus on the damage. It’s best to think about this when it is time to check the coils and sensor.

4. Replace Damaged Coils
Let’s assume you have looked at the coils and they are damaged.
What are your options at this point?
You will want to look at replacing the damaged coils as soon as you can. These coils are not good for the RV air conditioner and will do a tremendous amount of damage if you are not careful.
It is best to see which coil is not working and then replace it.
This is going to make it easier for the air to flow as it needs to.
Final Thoughts
Look at these steps if the RV air conditioner is not blowing hard.
If the RV air conditioner is not blowing hard, this means there is debris in the filter or excess ice on the coils. To fix the issue, clean the filter and remove the ice from the coils. If the coils are damaged, they will need to be replaced.
You will want to take your time doing this and make sure each part of the RV air conditioner is back to how it needs to be.
If you are not doing this, the airflow from the RV AC is not going to be on par with what you desire. This will make driving in the hot weather a tough challenge.
