What people are saying

Rated 4 out of 5 by from Does the job, beware if you dont clean it yearly After 3 1/2 years the heating coil rusted out and it had mold all over the blower and the coils.

Rated 5 out of 5 by from Best A/C Yet! This a/c unit is the best one we've had yet. Surprisingly quiet for the 18,000 BTU's power. Keeps a small condo (600 sq ft) comfortably cool even in Florida summer heat. Much superior to the two other a/c units we've had before this one. Highly recommend.

Rated 5 out of 5 by from Possitivly the best This unit was bought after the many reviews that I read. This unit is really quite, not the window shakers that you hear about. We put the unit on 76 degrees and it cools the whole house very comfortably in the hot Florida weather that we are experiencing this year. Installation was easy. This unit does the job!

I have a window that is 49 inches wide. So my question is how long are the accordion parts that are installed on the side? I don't see them in the photo nor are they mentioned in the specifications section.

When running the heat should the little stick you push in and out for vent. What position should it be in when I'm running the heat? Close, fresh air, or vent? 

Asked by: Ward Man 2
We appreciate your interest in this air conditioner. When using the HEAT function, it is suggested to have the Fresh Air stick in the CLOSED (IN) position to prevent cold air access.

when I turn the heat on it will not let me put it on energy saver how do I do that,

Asked by: TINAmayfield00117
We appreciate your interest in this air conditioner. The Energy Saver mode is designed to regulate the fan along with the compressor system. As the heater mode does not utilize the compressor, such regulation is not available. As such, it is not possible to activate the Energy Saver mode with the HEAT function.
