Improving the Airflow of an RV Air Conditioner

Over the years we've shared tons of tips and tricks for cleaning and troubleshooting an RV air conditioner to improve efficiency and airflow. We get it, when you're out on the road and the temperature spikes, all you want is to force your AC unit lower faster so you can get a little relief from the heat. Unfortunately, that's just not how it works!

Although he can't make your AC unit work faster, RV maintenance and repair expert Dave Solberg does have some additional advice for improving airflow inside the AC unit. Here

Cut and fasten the thermal diverter: Often when AC units are shipped and mounted in RVs, they have a thermal diverter that is crudely cut and weakly taped between the intake and outtake vents. When that comes loose and folds over, it can cause a cycle where warm, damp air just swirls around inside the unit without ever escaping and allowing cool air to enter. Dave recommends measuring the space inside the unit, cutting a thermal panel to fit, and using HVAC tape to securely fasten it between the vents. This will instantly improve airflow.

Tape, tape, tape: Anywhere you see rough edges inside the AC unit where the intake and outtake vents are not separated, go through with HVAC tape and cover them up. Create a tight seal so air can only travel out through the outtake and in through the intake, instead of just swirling around between the two.
