I recently built a seasonal home in central Wisconsin and noticed some condensation issues with my AC system. It's been pretty humid lately, and I found water pooling under the front left corner of the unit, which seems to be caused by humid air coming from the intake line. I checked the condensate line, and it's clear, but I'm worried about the water dripping onto the internals. Would it be alright to cap that intake line during the summer months when I'm not using the furnace?
Also, I've read that drain collars need to be installed horizontally, but my intake goes up vertically for about 4 feet before going out horizontally for around 9 feet. Is it okay to install the drain tee that far from the unit? The manual advises a 90-degree turn immediately from the unit, with the drain about a foot from the inlet. Lastly, are my vents positioned correctly according to the diagram I provided? This is a 96% efficient Goodman unit. Thanks for any guidance!

You definitely need to be cautious about capping that intake line. Those 96% efficient furnaces operate under specific conditions, and capping it could mess with their functionality. It’s best to leave it open year-round instead of risking performance issues. If moisture is a problem, consider consulting with a professional to find a safe solution.
That makes sense! I assumed capping it might help, but I guess it's not worth the risk. Thanks for clarifying!
