I had a mini split installed in my house last August and I love it. It's very energy efficient, super quiet, and had minimal cost compared to other options. My house is a split level log home. Bottom floor is very open floor plan, 1300 sq ft, kitchen/LR, bath, and 2 bed and the master bed/bath, 400 sq ft is upstairs. We installed one 24K btu mini split on the bottom level and it easily keeps the whole bottom floor cool. We use ceiling fans to circulate but the bedrooms that are on the opposite end from where the MS is, stay cool also. Our upstairs bedroom still has a window unit in it but I will replace it with a mini split when it goes out.

I loved the mini split so much that I had one installed in my 600 sq ft nightly rental cabin last November. I've compared my light bills for both my house and my rental (from the previous year) and it's always far lower. Both were previously cooled with window units. The rental cabin also was heated with space heaters so the mini split heat was a substancial savings this past winter.

FWIW, the single hose floor units are a waste of money and energy. Now a dual hose unit, especial a commercial grade one, that is worthwhile for certain applications.

I have a 10+ year old mini-split. Don’t make my mistake. Mine is an A/C, not a heat pump. When this one dies eventually, I will replace it with a heat pump. It gives me some redundancy with heating and it’s more efficient in the shoulder seasons than my natural gas boiler. It also would justify installing solar panels since heat is my big energy bill.

Generally, Mitsubishi has the best reputation for mini splits. Stick with the name Japanese brands and avoid Chinese stuff including Chinese stuff with US brands on them.

Look up Unico and Space Pak. These are alternatives to ductless and don't have ugly ac units stuck in the walls.

My only counterpoint to that is that the chinese stuff is 2x-3x cheaper than the Japanese brands so it's definitely a cost/benefit analysis.

I went with Midea (chinese) and for how little it cost, I plan to just replace the entire unit if there is ever a problem as it's cheaper than a service call. For example my 12k BTU 22 SEER hyper heat unit was $750 including shipping and a free lineset, the same Mitsubishi unit was $1,900 plus shipping plus lineset.

I've had my Midea systems for 3 years so far and zero issues. They even survived a big installation error on my part on day one plus another catastrophic issue this year when a flooring contractor cut through a refrigerant line inside the wall and released all the refrigerant. Just had to replace a section of refrigerant line and recharge the unit and it kept on trucking.

I'm not disputing that Mitsubishi and Fujitsu are the best- they are slightly more efficient (26 SEER vs 22 SEER) and are known to be more reliable. But wow the Chinese units are affordable and so far I'm really happy with them.

I have a coworker who says her neighbor has Spacepak, but she still has to have a few window units. For whatever reason, it does not work that well. She lives in a neighborhood with older homes as well. My sister looked into one and it was apparently going to take a month to put in vs. a week for the minisplit. There wasn’t a cost difference for her, but she ended up with wall units that are probably a bit too powerful. She has a home with architectural interest and the units aren’t that awful. I think they have 6 wall units and 2 outside units.

Carrier 17000, 17.6 SEER mini split in Bangkok.. 620 USD installed. Always seems like the HVAC people are ready to try one on, here. My brother paid about 3500 for Carrier with 2 blowers in VA, and about a thousand for labor and materials. I think his is 24000 BTU. 10,000 USD is crazy.

Decent price. Daikin are very popular in Thailand.
