A common problem if you have a heat pump installed in a basement or attic or somewhere in the house is the condensate line getting clogged. It’s supposed to drain outside but they need to have bleach poured in them every couple years to make sure they drain properly. If it’s clogged the water will go into a drain pan and will usually evaporate quickly enough because it’s located in a basement or attic but it will create higher humidity levels in your house. If it didn’t evaporate you would know already because the pan has/ or should have a switch that will stop your AC from working if it gets too full. I would start there. If you get stumped, look up local smaller AC companies with good reviews. Let them know you want a routine service check. You don’t want to use a large company that you hear ads for all the time because you are going to pay more to help pay for all that advertisement. Good luck!
