Anyone have experience with mini split condensate pumps? I'm thinking of installing another mini split this time in my basement that has just one walk out wall. Where I can I can install the unit has a concrete pad on the outside and I can see that using a gravity condensate line will leave me with a wet messy pad all summer. I'd like to be able to pump the condensate up to the underside of my deck past the pad and then back down to the ground. I'll just have to deal with the line in winter as it can get below freezing here. I'm assuming there's never any condensate in heat pump mode.

I've seen a few reviews and most people complain that these pumps are very noisy. Any recommendations?

I’ve been using a little giant brand condensate pump that I got at Home Depot for under $50 on a standalone dehumidifier in my basement for many years now. Yes, you can hear it when it runs, but that is for a short time, infrequent, and not of an objectionable pitch.

I would not install a mini-pump if I had the opportunity to directly drain out.

They are not ‘that’ noisy but just not the most reliable.

Thanks for the information so far. I've got two of those Home Depot / Lowes condensate pumps now. One on the main home heat pump system and another on the garage dehumidifier. I suppose I could just mount another one up on the wall directly under the indoor side of the split. I was trying to avoid having yet another thing sitting on the floor with another power line to plug in.

I really don't think I want a constantly wet concrete pad all summer under my deck so I need to move the water away. The mini split in the shop just drains by gravity but it's out to the back and keeps the plants happy.
