Would a mini-split heat and cool a 40x64x14 insulated pole building?
Is that something to even consider.
Thanks

Mini-split question
- Thread starter Cougar
- Start date
I have a 24’x36’x12’ tall insulated garage in central Indiana with a 2 ton, 24,000 btu min-split. it doesn’t even break a sweat. Keeps it cool and dry all summer and warm in the winter. Now, I barely open the garage doors, but when I do it recovers very quickly.
i could have gotten by easily with an 18,000 btu unit.

It'll be 102 tomorrow. I have a 40x56x16. 2 x 24k BTU will cool that building if I manage to turn the AC on in advance. I'm old, I've been running the AC in the shop for the last 3-4 days.Would a mini-split heat and cool a 40x64x14 insulated pole building?
Insulation is the primary factor though, I'm at about R12-R15, not outstanding... And have with 3 leaky big-*** doors.
Funny thing is, if it gets down below 25 degrees, I can't heat it because my Daikin splits were not designed for cold weather operation!

I have a 2 and 3 ton unit in my 30x40x18 garage (extra cooling is to rapidly add back cold air after opening garage door/brining in hot car) and today I had it set lower than I normally do on accident. It was a 100+ day today and my garage was at 76 in the late afternoon (garage was unused during the day). That is with one insulated double garage door, one insulated roll-up garage door and one man door and 2 inches of closed cell foam on the walls/ceiling.

I have a 24K EG4 mini in my 30x50x12. It's a little small based on the square footage, but is actually working very well. I set it on 78 and it has been maintaining very well in the last 2 weeks of 100+ days. It's mounted in the end of the building, so I will install a couple of fans to help move the air. I haven't seen the electric bill difference yet, but it will run off solar panels and that is the plan. I've been shopping for panels recently and will have them installed before next summer. I use a propane radiant tube for heat.

Also, I have 6" of insulation in the ceiling, but only the 1/4" double bubble wrap on the wall. 2-10x10 overhead doors are insulated.
As said, insulation is the key. I have a 30x50x14, open ceiling. I should have insulated the roof better, or had an insulated ceiling installed. Spray foam on the walls and bubble wrap insulation on the 3 roll up doors. I can barely maintain low 80s in Houston in August. But if it starts feeling warm, I just step outside and remind myself what hot and humid really means.

We’re about 250 miles north of the OP’s location, and I just installed a three ton (36k) BTU mini to cool the 32’x75’ x16’ high work area in my building with an additional 8k head in the 16x16x8 office / bathroom.
It seems like three tons will be sufficient, but the warmest days are past for this year. It’s been in the upper seventies for all but two or three days since the installation So I haven’t used it much. The building is pretty much thermally stable, but the mini seemed adequate for the two or three days of mid 80s weather it had to deal with.
The real benefit during those couple of teaser days was the dehumidification.
