High Humidity in our house
No disrespect, but this is a true story. We purchased the house about 5 months ago. It is a brand new house that was on the market for 2 1/2 years because the market was so bad. Our original home inspector did not do a good job. After we bought the house, my wife and I noticed that the bathroom vent was blowing air down at us. This is when we decided to have the house re-inspected to see what was wrong. This new inspector said that the fan was blowing in the wrong direction.
With regards to the air coming from the supply vents, we just don't know about this. We are going to have a blower door test and duct test to see if we have any leaks.
If you have any knowledge about this, please share. the humidity is now at 54 degrees as we have our thermostat set at 72 degrees.
