As everyone knows, cold air sinks and warm air rises. The cold air sinking thing is an efficiency robber of your air conditioners. With the "always open" floor ducts for heat and the heater return air intake ... essentially you are attempting to cool your basement (which serves as the intake plenum for your propane heater). If you go to Lowe's and buy the 2"x10" closable floor ducts, that will take care of cold air going down those openings. Then block off the return air return (mine is in the pantry), this will block the other big hole to your basement. Making these easy mods, your AC will work much better. BTW, the replacement floor air ducts don't even need to be screwed down as they sit in the existing holes perfectly, cover the existing screw holes, and aren't going anywhere (this makes them easy to remove to clean the ducts in the future). Of course they can be secured with the existing screws by using the old floor vents as a template and drilling the required two holes in each ... but they really don't need to be secured ... personal choice.
It's 90 (updated) here today (Kings Bay, GA) and the house is a very comfortable 76 (updated) degrees with our air conditioning cycling on and off. Much better than it was last year, before these easy mods. Just thought I would share with everyone. BTW ... Jetzen gave me the idea about the closable floor vents, so props to him.

awnings out on the sun side helps to shade the RV and reduce heat, covers on the clear vents & sky light. If your fans rotations reservable check the rotation.

with ronc being close to the Atlantic coast the winds can get pretty brutal and awning deployment may not be an option, but every little bit helps and you have to try to keep as much of your "conditioned" air inside as possible. So closing off those furnace ducts is a pretty wise use of $25.00.

Awnings make sense when possible ... I like the covers on the sky lights idea, just haven’t gotten there yet. Not sure about the reversing fan thing ... are you recommending to blow the ceiling fan down or have it lift up?

Not sure about the reversing fan thing ... are you recommending to blow the ceiling fan down or have it lift up? That is an age old debate, the fact is that it really does not matter in the overall temperature. Of course a fan blowing air on a person might comfort the individual, so it depends where he is located. |

During hot weather I always try to get my rig pointing north. Gives me the afternoon shade if I can't put the awning out.

Everyone down here has ceiling fans, every room in my house except the baths have fans. |

Remember - If you put the awning out, bring it in when you go away and at night before bed. You never know what comes up, even on a nice day.

We went to Lowes and bought and installed our new registers today. Lots of pet hair in those ducts! Now to figure out a cover for the air intake. Camping on the coast of Maine gives me time to think about it.

Camping on the coast of Maine gives me time to think about it. We used the silver bubble wrap stuff ... also at Lowes. It's for insulation, but works very well for our application. Others have suggested lining the exterior walls inside your cabinets for additional insulation. Haven't done that as our easy changes have made a big difference. |

Camping on the coast of Maine gives me time to think about it. I try to pull up the registers once a month an clean the duct inlets, as you say lots of dog heir when left open for heat ... As well when closed I don't know how it get in there but it seems to always have some Ugh !!! Off the subject, like Ron I did put some wooden supports from the floor to the bottom of the shelf that included the cloths hanger rods an shelf in our walk in closet as well this past year so that the shelf would not separate form the wall with a tone of cloths on it ... Cut notches in the support post so it would go around the hanger an then rest under the shelf, then screwed the support to the shelf ... Safe Travels Chuck |

Air purifiers at home end up with a lot of it stuck to the intakes. |

Wow, I never looked at the floor ducts and I made an assumption that they were the type that could be closed off. Guess not. We are pulling the rig into our driveway this Saturday and getting her packed up as the house will be completely empty this Friday. The house closes on the 29th at 9AM, and then we are headed west my friends. Back to the dry air of New Mexico. Our first night stay will be at the BUCKHORN LAKE RESORT just a little northwest of Kerville TX off I-10. This is our first stay at an RV park. It's going to be a hot week, so Saturday I will see if I can get the registers. Thanks for posting.
Bob

Thanks for the great idea. I have been wanting to clean my vents(dog hair) and it is a pain with the screws. Also we did note this trip that there was cool air under the camper. We don’t need to be cooling there. This was our first trip with 100degree heat. We usually try to avoid that. So we have done the silver insulation on all the windows , and the awning,which has helped tremendously but we will now add the vent idea. Thanks!
