High humidity problems
Hi. I would appreciate any assistance anyone has to offer. My home, which is supposedly very well insulated, often has humidity levels in the low 60s% and feels wet.
I have two Carrier HVACs: one in basement and one in attic above second floor. I don’t have a dehumidifier. The system only dehumidifies by cooling. The home cools well. Downstairs kept around 73 and upstairs kept around 72. Due to covid, we have been spending more time at time, so the house is almost always at these temps.
We have set the HVAC fans to always run. I have tinkered with the speeds in which they run, but that hasn’t seemed to solve the issue. We do have the overcool-to-dehumidify option on.
Also, perhaps related, the attic has been experiencing very sweaty ducts, often noticed when the system is working hard to cool in order to dehumidify. The attic is insulated. We conditioned the attic several months ago to try to stop the sweating ducts, but that has not worked and ducts still occasionally sweat
I would appreciate any advice on how to lower the humidity in the time and how to prevent leaky attic ducts. I am happy to provide more info. as needed.
