moisture in air supply


We have a new HVAC system and ductwork. The air blowing out feels damp. What would/could be the cause?:confused:

It,s probably just cold. You can not tell by feel you need to check the humidity.

some forced air heating system have humdifiers built in them. If your does check the settings on it. In the winter months it will add moisture into the system. So the air won't be dry.

Thumbs up

moisture in air supply


Thank you. I don't know if my unit has a humidifier built-in. It is an electric heat pump and air handler. The idea of having moisture in the air in the winter time is a great idea, just not in the summer time. This past winter, what little time that we needed to run the heat, there was too much moisture blowing out of the register vents. That was one of my complaints to the contractor. He didn't mention the unit having a humidifier though. I will see if I can find out about my system and give it a check.

didn'tdoit, The moisture is not from the humidity of the day but rather from the air that is blowing out of the registers. I.. feel.. the moisture in the air. Cold air filled with moisture is a lot colder than dry cold air. The HVAC is drawing moisture out of the room but at the same time blowing it back with the cold air through the vents. 75 degrees with 68% humidity, not good.

I didn't realize you have a electric heat pump. I don't know anything about those because they are popular in hot weather climates. You don't see them up here in the north do to the frigid winters we have.

747..come to think of it, we never had a heat pump in Illinois either. We lived around the Galesburg area for 15 years...Yes the weather
is frigid indeed. I remember one year we had a -62 degree wind chill.....and alot of snow..the weather is why I left town:D I will take the heat anyday over the cold. Thanks for responding to my problem.

Galesburg if i'm not mistaken that is about 30 minutes from Peoria. Meaning if your in peoria get on the interstate you will be getting close to galesburg in around 30 minutes...I think 74. isn't it. I could be wrong don't really know that area very well.
