I posted this on another forum and received some interesting comments so I would be interested in any input from knowledgeable members of this FR site.
I came up with this brilliant idea (in my own mind) to take the roof A/C cover off, clean up the interior and then cover the inside of the a/c cover with Reflextix
(available at your local box stores).
Anyway, the job was very easy and I covered the complete inside except the vent areas. I secured the Reflectix with dabs of 5200 to help in preventing any sagging onto the top of the a/c parts.
My thought is that the reflectix will reflect the hard Florida sun from the compressor and condenser and allow it to run a little cooler.
Running cooler might help improve efficiency and less overall strain on the a/c unit.
So, so far, after a week, it seems like the a/c is running far less than before (might be just a mind thing) but it does seem like a keeper mod.
After completing the a/c mod, I then removed the Max Aire covers from my vents and covered the interior of them with the Reflectix as well.
My wife had previously cut Reflectix pieces to attach into the inside of the roof vents, thus significantly reducing interior heat, but the area around the vents still seemed to remain quite warm compared to the rest of the ceiling.
I immediately noticed a very significant drop in temperature after my Reflectix addition to the actual roof vent covers. (This was not just a mind game - it really works).
Has anyone else done this?
How about long term effects?
Anyone have any pros/cons on what I did?
I have seen a couple of the more expensive window a/c units with a layer of insulation in them, so maybe this is not a crazy idea?
Unfortunately I did not do any prior measurements so if anyone does try this, please post some before and after results/measurements.
