Looking at installing a mini split in a 27 x 13 room with 8 foot ceiling. Was thinking of 12,000 btu unit, but don’t know if that is the right size, and what seer rating should I get? I’m located in Michigan, and the humidity is very high in the summer. I already have a commercial dehumidifier for the room. Just looking for some help.
351 square feet
2808 cubic feet

12000 btu is rated for 400 sq ft. Seer is just efficiency. Higher seer= more expensive. But more efficient.

You can’t base BTU needs on square footage like an HVAC guy does for a home. We need to base it on the lighting wattage we use in that space as well. To cover that space with lighting, you need to at least double the BTU of cooling.

Don’t fuck around with under-sized A/Cs that will disappoint you. I would double what you’re thinking. My 16×16 has a 24k btu mini-split that is able to handle the room. Try to get one with multiple settings for day and night or you may need to be there at lights on and off to adjust the thermostat.

@jmystro Thank you brother. I can do just that. I’ll get one with a WiFi thermostat.

You probably don’t need the wifi adapter for the minisplit. It just makes your phone a remote and doesn’t add features like scheduling. You want a smart thermostat that has scheduling. They use IR (like the remote) to control the unit.

I have a 15 k unit and a 8k unit in my 12×24 barn , The 8 is in my 6×10 auto room and the 15 takes care of my lung room that houses a flood table and 1k led bar light. I had a 10 in the lung that wasn’t cutting it . Definitely prepare for more. If you think 12 go 15 or more
