HVAC: Don’t shut your air vents to give you better heating or cooling in certain rooms/floors. You’re adding pressure to your system and reducing its life. If it’s AC then you’re turning it into a freezer. That’s why doing so freezes the coil, not enough air flow to move the cold air out and keep it from freezing. For heat it literally can overheat the control board frying it since the blower also helps cool the electronics. If you have hot and/or cold rooms (this is normal per floors) ask about adding dampers. Most of the time it’s not possible without major drywall rework and it isn’t cheap. Your builder sucks (basically). A lot of companies won’t quote the work because it can’t be guaranteed. You’re essentially stuck with the crappy design the builder got approved. One potential is minisplits. Again, not cheap per room and not pretty but they will fix your issue.
HVAC: mini splits
black mold forms and causes breathing problems. Clean aircons (air conditioner) every 6 months - 1 year.
If water is dripping from the outside unit, your aircon is lacking gas. Making it into a giant fan.
A mini-split is chosen to meet the needs for one room. Some folks, and can't be convinced otherwise, think an aircon can cover the entire universe. And to prove it, they leave all the doors open.
This is proof we live in the matrix. It's completely unsolvable issue without self closing doors
Water dripping means the cold side coil is cold enough to condense water out of the air. In what way does that suggest it is not working?
Normally the cold is carried by the gas to your room. The less gas you have, the less efficient this transfer is, and the colder your outside unit will be.
When the cold side is for inside air, I think you'll find that the water it condenses from the inside air is piped outside
