After using first frigidair for 5 years and still counting I needed AC for bigger room so got this one. Using it for few months does excellent job. Sometimes it gets so cold in the room that it feels like winter in summer. It's not heavy on electricity too as it's energy star certified. Unit started to have problem with fan function but Frigidaire has excellent customer service. Mechanical faults may happen so It's ok. I will buy same unit again.
