Coleman heat pump will not dehumidify
I have tried to read all the posts on this topic but still would like some help. I had a new heat pump installed two years ago. We had some issues with it on the heating side and they replaced the air handler last winter. Since then the humidity never gets below 50rh And most of the time it is in the mid 50's. They have tried many different thing but to no avail,( they in larged the ducts). Last week they changed the variable fan and slowed the air flow down. The RH dropped to the low 50's. Of course some of that might be the outside RH is lower. I have a Colman 8t I think and it is a 15 or 16 seer in a ranch style home with vaulted ceiling in part of the house. And it is 1400 sq ft. I am sure this is not enough info but if I had some questions to ask or suggestions for them, that would help. Thanks in advance.
