Ever feel like your RV’s air conditioner just isn’t cutting it? For starters, it pays to maintain your air conditioner properly throughout the camping season. But there are also ways to improve your air conditioner’s efficiency so you can stay cool and relaxed inside.
RV Airflow Systems are easy-to-install tools that can improve your air conditioner’s performance. But how do they work? And can you install them yourself? Let’s find out.
The RV Airflow System captures discharged air and redirects it into your RV’s ductwork. It installs between the bottom of your A/C and the cover plate.
It’s available for several A/C makes and models, such as the Coleman Mach 3, 10, and 15, the Coleman Mach 8, the Dometic Brisk Air 2, the Dometic Penguin 2, and GE A/C units.
The downside is that it eliminates the quick cool feature if your A/C has one. However, the improved efficiency largely negates the need for a quick cool.
Technician Tip: Your A/C quick cool should only be opened briefly to cool the inside coil so the setpoint is reached more rapidly. Leaving them open all the time can result in the freezing of the inside coil.
You’ll need a compatible airflow system to install in your RV, so here’s how to check if they’ll fit in your unit. But first, a key definition…
An air conditioner’s plenum is responsible for bringing in, distributing, and removing air.
Before we proceed with an installation, let’s get a baseline for your RV’s current A/C airflow and noise outputs. This will help you measure after installation to compare your A/C’s performance with and without the RV Airflow system.
You’ll need an anemometer for testing airflow and a decibel meter for testing noise output. When testing noise output, simply stand below the A/C unit inside your RV and hold the decibel meter at eye level. Record your reading for reference.
Technician Tip: Measuring tools must be used in accordance with manufacturer instructions to collect accurate data.
For testing airflow, turn your A/C unit on and place the anemometer next to each vent inside your RV. Test and record the airflow reading at each vent and note which vent you recorded. You can also add up your totals and divide by the number of vents to get an average airflow throughout your entire RV.
With these metrics recorded, you can set those helpful tools aside and proceed with your RV airflow installation.
Once you’ve determined your air conditioner can fit the RV airflow system and you’ve found a compatible model, here’s the basic installation procedure:
Technician Tip: The installation procedures may differ slightly for this system’s Coleman, GE, and Dometic variations.
Take out your anemometer and decibel meter again to test airflow and noise output after installation. You’ll test noise output at eye level while standing below the A/C unit. Test airflow at all vents throughout your RV. Record all airflow totals before adding and averaging them.
You can now compare your before and after readings to measure airflow changes at each vent. You can also use your average to calculate the percentage of airflow increases throughout your entire RV.
To calculate the decibel decrease, simply subtract the “after” noise output from the “before” noise output. The smallest change that most humans can perceive is roughly three decibels.
Technician Tip: The installation is easier than installing a roof vent or A/C from scratch, and the system really does work. In more challenging units, you may have to do additional system tuning by adding or modifying duct drops to get proper airflow through the unit. In smaller units, they aren’t really beneficial because the fan is drastically oversized, to begin with. But on medium to large rigs, they truly shine.
Even the best-laid RV plans can be ruined if you’re stuck in a hot, muggy interior. So here are a few more tips to stay cool and keep your air conditioner in the best condition for camping in hot weather:
