Refrigerant levels couldn’t be better, ac is running great, we are dealing with a ductwork issue, the crawlspace ductwork isn’t insulated and picking up all the humidity and pushing it back through the home, we only have 64 degrees coming from the vents and there’s no room the crawlspace for work to be done… I’d consider calling a general contractor to get the flooring up to get into the crawlspace easier and seeing if they are able to get to the crawlspace and ductwork.
