You'll probably want a split unit. Minimum $600 including install in Eastern Europe, but more likely to be over 1k.

Extrapolate salaries, cost of living and that's more like 3k in your money.

That said magic happens when government subsidizes things. Friend spent 8k euro for 10kW solar + 15kWH battery system, of which government reimbursed 7.8k. 1.35k USD for entire system, when you'd pay this much for someone to plug some cables for half a day.
