New motorhome owners need help! National Seabreeze

Hi all. We purchased a used motorhome and have no manuals! Question...why would the a/c be sucking in air instead of blowing out?

Tell us more about your new RV, maybe someone can point you to a source for the manual. Are you talking about a rooftop A/C? They don't usually have any controls on the air flow except shutting off louvers on individual vents. Is it a heat pump too?

Write down the make and model of all appliances and google them to find manuals for the individual systems.

The RV AC has a return air side and a supply side. Air is drawn in to the return air vent and then after being cooled is discharged at the supply air vents. It is a continuous operation of recirculating the air in the coach. The return air vent is usually on the bottom of the AC interior cover and the supply vent will be on the front and back side ends of the cover for a non ducted unit, or for ducted units will be discharged though the ducts located in the ceiling in the coach. Do you have a ducted or non ducted AC. What brand and model is it. You can usually find this information by taking off the interior cover \

Welcome to the forum and congrats on your new rig.

Even the complete set of manuals which come with a new coach are really just a stack of individual manuals for the appliances and then usually one for the "house" itself and maybe one for the chassis. Check out all of your appliances and Google the make and model number. You'll be able to download nearly all of the manuals.

It would help us all provide more insightful responses if you would put the year, make and model of your coach in your signature line. You can do that via the User Control Panel.

Best of luck.

Some AC units have a dual mode so they can act as a vent in mild climate

Sue & Mike-
Welcome to the iRV2 "Family". We're sort of dysfunctional depending on the functioning nature of our RVs from time to time.
Good first question BTW.
You can post pictures by uploading your pics to iRV2 under Photos at top of page, then go to the photo, right click on it & Copy Image Location, then in your post click the small mountain+moon icon above the posting box & right click/paste the url of the photo in the dialog box. This is another way (especially good w/older or limited mintage rigs) to get good feedback, in addition to adding a signature (like mine below) to your User Profile under UserCP above.

Boy do we feel pretty dumb now that we figured it out! What we thought was THE A/C was the intake and those round thingies in the ceiling were the vents! Thank you everybody!
