RVing in the summer offers lots of fun, but it can create some challenges, especially with cooling your RV. The performance of your RV air conditioner can vary widely, depending on the weather outside. On a hot summer day, it can often seem like your AC is barely able to keep up. Luckily, by helping your AC work smarter, not harder, you can significantly increase the comfort of your living space. That’s where the RV Air Flow System comes into play.

The RV Airflow System is a DIY modification to your AC unit, providing better redirection of air through your existing ductwork. It’s affordable, easy to install, and can have immediate effects on your RV’s comfort. The system is designed to work with many AC systems and can be customized if needed to fit your special needs.

Introduction to the RV Airflow System 

The RV Airflow System is an innovative, patent-pending module designed to optimize your air-conditioning unit by improving airflow throughout your RV. The easy modification is installed in the empty space in the bottom of your air-conditioning unit, referred to as the plenum. This non-mechanical device reduces air friction and turbulence within the RV ductwork, providing a more efficient way of redirecting cool air throughout your RV. This system is beneficial for most RV air conditioners in travel trailers, fifth-wheels, or motorhomes. It uses the existing duct work and ac vents.

Material and Durability

The RV Airflow System is made in the USA and is crafted from the highest density 3lb Expanded Polystyrene (EPS). Built to last, this material is water resistant, durable, and designed to prohibit mold growth and mildew. It’s a great product for anyone with an RV AC system that just can’t keep up with the summer heat demands. The system will last as long as you have your air conditioner. 

Key Benefits

  1. Longevity and Efficiency of A/C Components: The RV Airflow System reduces air friction and allows your RV to work with less resistance. This slight improvement may help to extend the life of your A/C components, potentially saving you repair and replacement costs. The appliance industry recognized that the RV Airflow System significantly boosts the performance of AC units, even under full sun and during the heat of the day.
  2. Quiet Operation: The system significantly decreases the noise level of your AC by 40%. This was confirmed using a decibel meter. By allowing the air to flow more freely, most RVers will notice a definite noise reduction immediately.  
  3. Consistent Temperatures: The unique styrofoam insulation design optimizes the discharged cold air volume and balances airflow throughout your RV’s living area. This eliminates hot or cold spots, creating a more consistent and comfortable indoor temperature, even in hot weather. This is one of the top reasons RVers make this upgrade. It can eliminate the need for a second air conditioner if you’re primarily having problems keeping certain sections of your RV cool.
  4. Economical: The unit is also economical and may save you thousands of dollars required to add a second unit. The RV Airflow System costs just a fraction of a new AC. Additionally, by being able to quick cool your RV with proper airflow, you’ll lower your electricity use, even on the hottest days.

How Does the RV Airflow System Work?

​The concept behind the RV Airflow System is pretty simple. If you picture your AC unit, the air is flowing downwards out through the vents. The pressure pushes some of the air into the ductwork distributed throughout the RV. The problem arises as the air pressure pushing the cooler air through the ductwork is variable. This means that some vents get more air than others, while further away, ones may get very little.

The RV Airflow System solves this problem by capturing 100% of the air from the AC unit and pushing it all into the ducts, providing a much better distribution of discharged air throughout the RV. This system provides much more even cooling in the RV and solves the problem of hot and cold spots, and normalizes your inside temperatures. Additionally, it eliminates air leaks which lead to inefficient cooling. It’s simple but ingenious.

RV Airflow System Kits are available for many AC units, with custom-built options available to ensure near-universal compatibility.

How do you install an RV Airflow System Kit?

Installing an RV Airflow System Kit is easy and straightforward. Only two parts of the system need to be installed: the duct adapter and the diverter. You start by removing the inside cover for your RV. This will expose the opening that is behind your filters. This can be done with a screwdriver. Once removed, the next step is to install the duct adapters, which will create an airtight seal between the diverter and ductwork. Depending on your kit and AC unit, you may need to trim the duct adapters.

​Once installed, next you simply push in the diverter and secure it with bolts. Finally, you reinstall the inside cover and turn on the RV. Since there aren’t any electrical connections or moving parts, you can accomplish this DIY modification in less than 30 minutes. For a detailed overview of this process, check out the following video:


Compatibility between the RV Airflow System and your specific RV model is crucial. RV Airflow Systems have simplified this process with their detailed compatibility list. If your RV model is not included, they offer a customized system to fit your RV’s ducted system specifications. Below is a list of RVs with a stock RV airflow Systems kit. The exact kit will depend on the specific air conditioner model installed in your RV.
