Installation & the rules that apply
This is a portable monobloc. The most regulation-light option by far. No EPA Section 608 certified technician is needed because the refrigerant circuit is factory-sealed and never opened, no building or mechanical permit is triggered since nothing is fixed to the structure, and a landlord has little ground to refuse a unit that leaves no permanent alteration. The real constraints are your lease or HOA rules on how the window kit looks from outside, and noise to neighbours.
