LG Split HVAC with dehumidifier
We built a PassivHaus with a Silver rating. We are in the South so it is hot and humid. We have a mini lg split with a dehumidifier and an ERV system on our 2200 sf home. We have been in the home for 4 months now and cannot get the humidity under control. It is currently between 71-80% at any given time. Seems to increase when we turn on the dehumidifier (80%). Our smoke alarms have started to go off when it gets that high. My shoes have molded and the sheetrock tape is bubbling off. The temperature in the house is lovely, but it feels and is wet. We do not have any condensation in the house. We FINALLY have an appt with the contractor who installed the system. What is going on here? I want to be armed with as much knowledge as I can before they come. I hope I have provided enough information.
