Air Conditioning for Small Room (12m2): Installation Costs & Energy Bills in an Old Apartment

Hello.

Due to the fact that a year ago the heat was unbearable, and with the computer turned on it was a tragedy at all - I live in an old block of flats on the 8th floor, fortunately from the north, but summer is unbearable.

What would be the cost of air conditioning for such a room? My room is in such a place that behind the wall I have this kind of a pseudo balcony with escape ladders, accessible from the corridor - so I could install the other part of the air conditioner there - although I will probably need to have the building administration approval.

Another thing is that the electricity bill will probably get a lot ...

To such a room, basically every one on the market - if you plan to buy for years - I recommend something good - Fujitsu or Daikin, Mitsubishi, Toshiba. You have Chinese from the market for 3-4 seasons.

Air conditioner LG STANDARD P09EN 2.5kW inverter - I found such a thing on a known site at a price of 1670 PLN new with free delivery. Will it take a little?

or at a price of ~ 1100 PLN new KAISAI ECO KED-09KTA 2.6 kW. Although I realize that probably this Kasai belongs to the category of "Chinese", although maybe it's not that bad?

What are the installation costs? Unfortunately, I don't know anything about it, so self-assembly is out of the question.


I will mention that the air conditioner will not be used very hard - probably only a piece of June, July August when temperatures rise - if there were 23 degrees in the room. In addition, the sun does not watch my room at all, the windows are tight, the building is insulated and already in mid-autumn I have heating from the municipal network.

I have several LG on site - I can't comment on durability yet - they've been around for two years.
On the plus side there is definitely quiet operation and at least very good energy factors on paper.

I recommend gree has been mounting for 7 years and no complaints
