The Air conditioner I bought from Safe National of America was working well. But after six months the exhaust broke, so I technically had to get my husband who’s an electrician look through it. He said that some wirings were made up of substandard materials that could easily spark up. I’m glad it broke otherwise we wouldn’t have known the harm it could potentially cause if that flares up. My goodness, we could be homeless if God forbid that happens. I wrote a letter of complaint to the company insisting them to return my money, it had just been a few months. The thing I’m fretting about is their electronics are totally unsafe.
