    Hey Rob, was installing the RV Air Flow system in the second A/C worth it?

    Thanks,

    I installed the RV Airflow kits in both of our units. I was disappointed at first, particularly because the company never returned calls to troubleshoot. Fortunately (maybe unfortunately?) our unit had to be re-roofed, and while doing so an issue with our racetrack was discovered and corrected. Now they work well! We have found you really need to close one of the bedroom ceiling vents or it's a bit too much air force. We have also found that if we set the bedroom thermostat 2 degrees cooler than the living room, the units better collaborate and keep our coach very comfortable without big swings.

    To us it was because of the way we use our ACs - for example, alternating for day/night use when possible. We are also full-time, so air flow vs. noise is not just a weekend or vacation thing for us. We don't have a stix 'n brix home to maintain, so we spend our money on things that make our home on wheels suit our needs and as comfortable as possible for how we use it. Your experience may vary based on your use, etc.

    Rob, how long did it take to install the second RV Air Flow system?

    Second Chance is right. It is your call. But like he and others have said since both units are on the same ductwork, you don't need the bedroom unit running. Also, the vents on the actual AC units should remain closed to ensure a good flow of AC thru the ductwork. If I recall, the AC manual pointed that out as well. Unless it is major hot, I normally only used the living area AC.

    Greetings:

    We were recently visited by an RV Mobile Technician (replacing our converter) that was also an HVAC specialist. He explained to us that when we are not in the rig, it’s best to leave the vents fully open on all ACs because they are most efficient when they are maximizing cooling directly into the unit, rather than through the ducts.

    In short, he explained that because the cool air travels through the duct system (which is generally close to the exterior walls and ceilings of the unit), the air heats up incrementally by the time it exits the separate vents throughout the rig, depending upon how far the vent is from the AC unit. This is a acceptable when you’re in the unit (say the bedroom), because you’re likely feeling the volume of air coming out of THAT specific vent, but it actually makes the unit(s) less efficient overall in their ongoing process of cooling all surfaces inside your rig… which your thermostat responds to. Thus, when you’re gone, it’s best to let them blast the concentrated volume of cold air directly into the insulated spaces of the rig, directly out of the AC unit, rather than diminish the cold air through distribution at the various vents around the rig. He noted that in some cases, the air may be as much as 3-5 degrees warmer at the individual vents than at the central “dump vent.” Hope that all makes sense.

    Anyway, we followed his advise and have noticed a SIGNIFICANT reduction in the frequency of cycling of the system… and we’ve been experiencing 100+ degree temperatures over the past few weeks.

    Don’t know about the experience of others, but this has been substantially effective for us.

    Our unit came with one RV Airflow installed in the living room unit, none in the bedroom unit. (Thinking about adding it.) We normally set the living room thermostat to the temp we want the coach to be with the fan on low. Then we set the bedroom two degrees higher with the fan on high auto. This creates a 2-stage effect. As long as the LR unit can handle the load, it’s the only thing running. If it can’t keep up, the BR comes on at high speed. If the LR satisfies, the fan will continue running on low to circulate air. At night we lower the LR thermostat 3-4 degrees because we like it cooler when sleeping.

    Since we don’t like listening to the air conditioners run.

    And since the whole duct work is tide together, and one air conditioner in most cases is adequate. We run the one in the living room at night. And during the day from the one in the bedroom. That way we don’t listen to the noise of the air conditioner run.

    That's exactly what we do, and it works great.
