Floor vents

[jpbuch9309]

We are full timers with two dog I pulled up the floor vents and hot glued window screen to the bottom of the vents so no crud fall in

here is a pretty good idea I just saw online

They have filters on the ACs but tell us not to do it to furnaces.
The intakes are small, but if the filtering media or screens are monitored and changed should not be a problem.
Just think of all the dog hair ingested and deposited somewhere in the furnace system or lint etc now.
We don't hear much about furnace fires ,though, in RVs.
There are different meshes of wire available. I haven't looked in years so I don't know about availability. A coarse grid would stop a lot of junk and no inhibit flow, if kept clean. This is the thing. They are afraid people would not clean them. Is there not a thermal shut down on furnaces to shut them down ff they get too hot?

I would recommend that you remove the screening if it is truly window screen screening. You will actually dramatically reduce air flow and you can cause over-heating and premature shut down of the system when you need the heat the most. Air flow is reduced by at least 50 percent and if any of that crud has accumulated on that screen it the amount of reduction will be increased.

I've read that butter works real good.

Bob, are you watching?:B

FWIW, here, at the sticks-and-bricks, the Polish Princess has polyfill across a few vents. She thinks it keeps the ducts cleaner.

x2. Sometimes we forget to remove them when we fire up the furnace. Hmmm nothing like the hot rubber backing smell. 🙂

It seems to me that dust and some sand etc. will still get in past the new screen. Larger stuff will collect on top of your new screen and block the flow more. Like someone said I would just remove the vents once or twice a year and use a shop vac in them. That's what I do one rental mobile homes. Be care not to tear the duct loose. A lot of times you can slide the shop vac hose down the the duct for good cleaning.

I just remove the two screws when vacuuming.

I was thinking screens reduced air flow by more than a very small degree. But, didn't know the amount.

The screen probably restricts air flow some but to a very small degree. The kind of crud is the dust that comes in, whatever might be tracked in, yours, the dogs, visitors, etc. If you were not aware of what kind crud falls in, you probably dont have furnace vents in the floor or have never looked and checked them.

Won't the screen restrict the air flow?
And, what kind of crud was falling in the vents? :B
