LESLIE: Joe in Illinois, you’ve got The Money Pit. How can we help you today?
JOE: I have a single-story house that’s got hot water. I’ve got a boiler with a hot-water heat baseboard. And about eight years ago, I had air – central air conditioning installed.
JOE: And when they did all that, they ran all the trunk lines up in the attic, put all my registers in the ceiling.
TOM: Yep. Mm-hmm.
JOE: And now the problem I have is during wintertime, I’m getting condensation. You know, I’ll go around and shut those registers off but it’s not 100-percent shut-off on those registers, of course. And I’m getting condensation that’s forming up in my trunk line and I’m getting condensation dripping out of my registers, which – I’m starting to get some water stains on my ceiling around my registers from this.
TOM: Alright. So you have an energy problem. The problem is that those registers are so cold that when the warm, moist air from the house strikes them, it condenses. And so, you need additional insulation in the space above that. You may need to insulate in or around those ducts. You may need to wrap those ducts with additional insulation. You need to keep those ducts warmer and frankly, the bigger problem is one that you can’t see. If it’s that cold at your ceiling, you’re probably losing a lot of heat through that ceiling. So, I would get up in that attic space and take a look.
In your part of the country, having 15 to 20 inches of insulation is not unheard of and it is certainly a good idea.
JOE: Well, basically, I know when they put it in there, they laid those trunk lines right on top. I’ve got like 20 inches of blown fiberglass and they laid those trunk lines. I need to peel that fiberglass back, bury those trunk lines and insulate all around that real good.
TOM: I think that would make a lot of sense.
JOE: Sounds good, then.
TOM: Alright, Joe. Good luck with that project. Thanks so much for calling us at 888-MONEY-PIT.
