Hello, A manual J would tell you what you need for the room. 9000 btu,s is 3/4 of a ton. Depending on needs, this is small to overkill.

I would not use a minipump if possible. I installed 3 units while the masterbed rm gravity drained to the exterior.the other 2 bedrooms high wall units pumped up to the attic then drained into a plumbing drain stack. The intermittant noise was an issue for the bedrooms. I went back and wraped duct insulation around the pump to help quite it down. It was not extremly noisey but noticable. I probally could have placed those 2 rms on the exterior and drain directly out . but may not look to good on a 100 yr old house front facing.

"baseless propaganda"? There wasn't a single item stated to warrant such an irresponsible response. Dismissing a truthful message and then attacking the messenger in such a patronizing manner is a common protocol for one living as a cartoon character elitist in a faux fairyland euphoria so it wasn't offensive and expected. You're right, people aren't going to stop using air conditioning but at some point many will lose the entitlement to use it. Some prefer to stay ignorant to a lot of things while they sit in front of the air conditioner with total complacency, unaware their entitlement is on the chopping block. It's all by design so Lets jump back 10 years, California seeks control of thermostats and then three years ago Let PGE control your thermostat and last year. PGE time of use plan. In this case the past has given a picture of the future, and 82 degrees will be the setting because they swallowed the propaganda from their masters, but the funny thing is California told everyone what they're going to do 10 years ago but the free cool-aide was so sweet it was missed. By the way 18,000 businesses have left California over the last 10 years and Oracle and Hewitt Packard are in the process of moving out. HP was the first Tech corner stone in silicon valley and will be a sad day for California but those 2400 good HP jobs aren't needed in the state, right?. Close eyes, click heals together 3 times.

Yeah, pulling a vacuum doesn't seem to be that big of a deal, no one is willing to touch it anyway, so I have no choice but to do it myself. Main concern is too much pressure because of the amount of coolant I can always go back to the 16-foot line set, just don't want to have a big coil of line if I don't have too. Thank you for your time.
