Should I have let the ac guy close off a return?


I have a 2000 sq ft house in Florida with ac problems. I replaced the unit 4yrs ago, been running fairly good since then however, in Dec 08 the unit froze up (not from the low temp it was in the 80s that day). So I had someone come out to look at the ducts and add freon. This guy tells me that he wants to close off the return from the master bed (its very small) and "seal the return box". The return box is right over the return in my kitchen. He charges me $200 to close off the master bed return, add freon, and cover the return box with mastic to seal it. From reading some of the other posts, now I am thinking I need that master bed return opened and possibly adding another return. The master bed and other bed on same side of house are always hot. The newest problem I am faced with is the return box appears to be falling apart from the inside, large chunks of insulation are in my coils which I think is why this week the ac cant keep up with the set temp. I set the temp at 79 in the morning and at 3:00 its up to 82 and the unit doesnt stop until around 8 or 9 at night. And this isnt even the hottest part of summer. I am hoping that by cleaning the coils my ac should work better now, but what about the master bed return? Anyone have any suggestions?

Leave it open. Most the time you can not have enough return air.

As long as the supply air is sized correctly an unrestricted return is OK. However, the return air needs to sized as well.

If the coil has insulation in it then it needs to be cleaned

I would get a second opinion

Yep, all the above.

Cut off one return makes the other draw harder but they won't move more air.

And, causes any leaks in the return duct work. To draw more air from unconditioned space.
