Question: What are the setting for temperature knob
Document: It'll constantly run at the highest setting but then you wake up feeling like an ice cube.
This unit has been working very well in my room at college. I live in a house with no central air, but this A/C unit has been keeping the room cool on a low setting.
It's quiet, powerful, easy to clean, and profoundly durable.To get the front off for cleaning follow these instructions.[... ]You can use a garden hose on the "flat" setting to clean the fins. (Yes inside, while it's still in the window, it only takes a couple seconds.) The vast majority of the water goes outside. A towel rolled up underneath takes care of the rest. Way easier than trying to use a brush or something.
I bought this unit 4 years ago. Overall, I don't need to use it all that often, maybe just 20 days a year. That being said, it still works well and keeps my bedroom cool as needed. The only problem I have with it is that it turns on and off too frequently to maintain a given temperature. This can make it difficult to fall asleep at night.
the filter on the back looks like its been kicked, its not even the same as the one in the picture, it didnt even come with the seal strip like the manual says its supposed to have the ac that was sent is an (LG) not a (Goldstar) its not even understandable!
lite weight, quiet when running, comes with vinyl slide out pannels for left and right sides, easy install in 36 inch wide window opening, plug into any 110 volt outlet, uses about 4 amps, the front pannel below the air outlet folds down on hinges for easy filter access. perfect to cool one room all the time, or keep in garage and use when the central air breaks down on friday and parts aren't available until monday. one cool room is better than no cool room.
keep cool.
it's sad all the bad reviews but honestly when you buy the cheapest thing on the market your going to get a few duds i bought 6 for about $600 tax and all they kept my house nice and cool they are for a small room after 1st year one started to shock when touched lol 2nd year one started making a noise 4th year i ran a screw in one by mistake freon leaked out 5th year i lost 2 of the last 4 this year i'm only using one at the time.
i can turn it on one room then at night turn on the batroom for bathtime it dropped me electric bill like $200 a month so 6years x 4months x $200 = $4800 - $600 =$4200 in savings much better!
Was a good deal when I purchased the small window a/c, and cooled nicely for about 1.5 years. Now, it doesn't cool at all.
Answer: Hi John, The temperature knob goes from 1 to 9 with 9 being the coolest setting. There is a 'fan only' option and a fan speed setting of high/low. There is an on/off switch too. If, however, you turn the AC off, you must wait 3 minutes before turning it back on again. The vent has a hand adjustment on it to direct air right, left or straight up from centre. It uses less electricity than our old Frigidaire 5K BTU AC so we are able to leave it on 24-7 most of the year. We leave it in the window all year and with our living room's ceiling fan it keeps the house cooler than our central air did in our old house. Hope this helps you out John. Oh yeah and we bought our Gold Star AC used yet it runs like new. We have no complaints. Have a safe & happy 4th of July all- Jack/keimanzero in Campbelltown PA.
