I live in Houston and have a split-system central A/C unit. I've only lived in the home a few months, but I was taking a look at the inside unit which is installed in an elevated closet (with the space below the unit being the return air vent). And I looked straight up and noticed this closet is not divided from my attic in any way! In other words, I can see the top of my house when looking up through the A/C closet! Is this right?? It sure doesn't seem to be. If it does need to be insulated from the attic, does anyone know if I need to adhere to any special guidelines when sealing the closet off from the attic and eventually insulating it? Any and all help is greatly appreciated. Thanks in advance.

How old is the house?

In that climate a good design is a conditioned attic where the attic floor is not insulated and is part of the house. The insulation is on the bottom of the roof.

But that is relatively new technic.

The house is older...22 years this year. So the attic floor is insulated. I called the local HVAC repairman and spoke with him (he'd been out to inspect my system when I first moved in and seemed genuine at that time), and he said that all the houses in my neigborhood with the 'closet unit' are designed that way and as long as the door has a good seal, it's not a problem. I don't see any problem with the door having a bad seal, so I think I'm okay there. Any other suggestions?
