Diffuser Condensation Central Air
So we had Central air installed in our house. Northeast New England region. 1 floor - Garden style, 1700sqft. So I'm getting condensation on the diffuser/vent in my kitchen and the one in our daughter's bedroom.
Here are some things I checked:
1. Went into Attic and verified all the diffuser boxes are wrapped tight and covered with insulation as is the ductwork with R-10 value insulation.
2. Made sure that our Thermostat stays between 70-72.
What's weird is that the Kitchen is the first stop in chain for the ductwork and my daughter's room is the last.
It goes Handler>Kitchen>Living RM>Living RM>Dining RM>Bedroom>Bedroom (Total of 6 diffusers). All 10x10" except kitchen which is 12x12".
We have three returns. One 9x9 in each bedroom and a 15x9 in hallway/open space that connects kitchen to living rm and dinning rm.
I called the company that installed and they are helpful and do return calls and e-mails. However, they did say there's probably nothing they can do on their end but they would come out if needed. The ductwork does have dampers before each drop. I wonder if I should try this?
Anyone ever had this issue or knows of someone who did and how to resolve it?
there would seem to be a gap in the insulation coverage or the inslulation is compressed. Insulation reqires the air gap trapped inside it to provide its rated R value. You can cover the vent in the attic with more insulation and see if that helps.
agree with turnermech seems like more insulation is needed around duct to prevent it from condensating...:yes:
