An important point was missed. The GWP effect is when there is a LEAK! not while it's in the system. When & IF it leaks when there is a fire, it will propagate the fire!!! Also, very important flammable A2L (R32 or R454B) might and could INTERNALY explode. This is true if the vacuum process (must be higher than R410A an A1 class non-flammable, non-explosive class) is not perfect (presence of moisture/oxygen) as when compressed the temperature could reach the lubricating OIL ignition temperature, and in the presence of flammable refrigerant (any A2, A2L or worse A3) the oil might ignite the flammable refrigerants! This possibility will not exist if A1 class non-flammable refrigerants are present. Neil Afram Director of Space Air Ltd. distributor of AC & Heat Pumps since 1980.

Purchased: August 2023 - still works GREAT!I ru-vid.comUgkxxsUnXhGsSJLim_XnMHyQK0u3XVaW-CGn live in a studio and during the summer it gets scorching hot - really old building with no ac units. I can’t express how EASY it was to install. This unit has been a life savior during the summer and some days during other seasons where it can still be a bit warm at night. In this small place is my friend, a husky, poodle mix and myself. We need AC - lolI don’t use the dehumidifier option - I’m not sure if it will leak in my house, since I did not install the small draining hose that came with it. May look into it late but I don’t worry about much humidity in the apartment. I don’t understand why the negative reviews since all things mentioned, I personally did not find issues with. Definitely worth it!
