New homeowner and I'm troubleshooting my HVAC. The two problems I have are: -HUMIDITY!!! -Temperature difference between main level and downstairs (which is half an unfinished basement and half a finished basement that feels like a normal level of a house due to windows and high ceilings). The downstairs has significant levels of humidity: ~69-70%. The main level is around 60%. These levels have been consistent for a month (without much rain, so I don't know where all this moisture is coming from). It's summer and hot where I live so we have the AC on auto. I just bought a dehumidifier which is helping, but I'd like to see if there's anything I can tweak with the HVAC. It has two condensation exits that both feed into the same tube (see pictures). Unfortunately, the drain isn't right next to the HVAC and the bottom exit is pretty close to the floor, so most of the tube is flat on the floor. I picked it up to help it drain and there was a lot of water just sitting in it. Could this be contributing to my humidity problem? How can I fix it? As far as temperature goes, there's about a 5° difference between the main level and downstairs with downstairs being colder. We closed the vents downstairs to try to equalize the temperature, but is that the best approach? What would you recommend?
