I would like to try my luck at getting a portable ac, again. Last summer I bought a reconditioned LG portable. The temp in my apartment was about 85F. I installed it as per instructions but instead of venting via the window my apartment is equipped with a vent hole right through the wall. That is to discourage window units that are not allowed as per the lease. A few seconds after installing and turning the unit on it began to blow cool air. The default temp setting was 72F I believe. I initially thought oh great. I let it run hoping/expecting my tiny apartment tool cool down soon. After about 2-3 minutes the compressor kicked down, which I thought was strange. After about a minute it kicked back in and started blowing cool air again. But then in less than one minute it kicked down again. And this continued on a continuous basis. Blowing cool air for less than a minute and then shutting down to just the fan blowing warm apartment air. I really didn't want to have to take it back if I could help it because I don't drive and it is a big hassle trying to find someone to take me or paying a car rental fee. So I called the manufacturer and they said to try let it run like that for 24 hrs to see if that would fix it. Nothing. I tried calling local ac techs and they said I probably just got a bad one. So I took it back and got a replacement. After going through the same steps again I got the same results. So needless to say I was pissed. So I took it back for a refund and just bought a couple standup fans. The weird thing was that they had a lot of these ac's with varying BTUs and they all were in new boxes. And both units I got appeared brand new. in every aspect. Even the packaging. The only thing I can think of that I did that may have been the cause, was I had to lay the box down on its side when travelling. But I was informed that as long as I let it sit upright for 24 hrs before turning it on I should be OK. Well I let (them both) sit for approx 36hrs. So do you think that caused it? I really would like to get another one for this year.
