 You've got to make sure that filter is clean so it has good air flow through the system. That's the key number one thing. Also, your unit is taking a lot of humidity out of the air, so those drain lines need to be clear and they need to be working. So if you can check them, great. If you want to have a good professional company, I can recommend one to come in and make sure those drains are clear because if not, you're going to have a flood.
