I’ve only had this a few days, but I am thoroughly impressed. I have a big house (too big) and I hate running the AC constantly in this big place just to cool in my bedroom. This is not just a cooler. It is a total HVAC with fan D humidifier, refrigeration and heat. Perfect for my bedroom area. Cool is really fast, noise level is about what you would expect, I do hear it, but it’s almost like white noise, not a problem. I’m on a medication that gives me these horrible, hot flashes and night sweats. This thing is wonderful. Just press the cool button on the remote control and within seconds I feel a cold blast. For me, this is a godsend.

WOW so far worth every penny! Purchased this unit for our 26 ft camper, very cool on hot nights (running about 70°) and just used it during a cold snap for heat. Must say great unit

UPDATE: 11/2025 GIVING IT ONE MORE CHANCE: Attempt to use HEAT mode during our first winter cold snap. NOPE, all it does is blow cold air, not one bit of warmth coming form this machine. We have cleaned all filters and done reset. Additional this particular machine has never given me an ERROR message code as I see other reviews talk about. I guess this one is just a complete dud. Will contact customer service but am out of warranty now by two months. They will want the item returned at customer expense not considering the customers have already dealt with extreme frustration due to this ineffective product. My review went down to one star as I originally gave it two stars, because I hoped it would redeem itself for the winter months. Such a let down. Very disappointed with this brand. The window adapter for the vent hose if very flimsy, first you will have to cut part of the slider off (if your window is not exactly the right size) to make adjustments. The vent hose (it's honestly too long and too heavy depending on your window) keeps popping loose from adapter, has hooks where it is to snap in place on the adapter but that does NOT hold it. Eventually I had to completely remove adapter and shut window down on the part that blows all the hot air out and cover up the rest of the open window with towels and weather stripping in attempts to keep hot air from coming back in. Secondly, the hose gets extremely hot, to the point where you can feel hot air blowing from the hose near where the hose attached to the machine. I wrapped weather stripping there first, then I bought the aluminum foil HVAC tape to stop the leaking in of hot air, once that leak was improved you can tell it is putting cold air in your space. Hence I did give it two stars, but all the work and effort I have put into it, probably should only be one star. It was also very difficult to keep the vent hose attached to the back of the unit. It is a twist lock in place design, which is flawed. Needs to be sturdier, It came loose one day, fell and knocked the drain tube out from tote bin that I have the condensation draining in. There was water all over my she shed floor. I see the pictures from other customers and no one ever mentions how much water comes from the drain hose. I assume they have their hose running through the wall or something. I did see one with it dripping in trash can. That would not contain all my water. My drainage tube drips into a huge tote bin. Of which, every morning and evening I have to dip it out. I use a 2 quart bucket, making at least 4 trips to empty it out on my yard. It is just not mentioned how much condensation to be expected. I guess if I was able to cut a hole in my wall and get a longer tube this could be resolved but I am not in a situation this could be done. The temperature here is in the 90's. I purchased this product last August 2024, during that summer I just finally let my building stay hot as I wasn't dealing with fixing the building up as I am this summer. Thought I would give it another chance this year, and all I have dealt with is problems. The heating side of the Serene Life AC and Heat product was a total bust. All it did was blow cold air back in. No help in getting any warmth, went back to using the radiant oil type heaters. This product functions like a heat pump and it was very cold. There is no putting it on heat strips as you can do with you home heat pump unit. Prepare for these glitches if you buy. Maybe the designs have been changed since I got mine, but it is risky and not worth the time. The sq footage that it is to cool and heat is acceptable but it has not been worth my money. Maybe if you are cooling a small room, and have a plan for your drainage it would be okay. Controls work fine on machine and the remote. I am preparing to put in mini-split level now to replace this thing.

We live rural and in temps no hotter than about 95 degrees for about 3 hours it really helps our 1000 sqft room stay perfectly cool. My wife would say cold. The only reason I didn't give it 5 stars is the remote doesn't know what the unit is doing. So if I do not start the unit with the remote, when I finally go to use the remote after the unit is powered on manually it changes all the setting, meaning when its on low if you hit the remote it speeds the fan up from low to medium. I don't use the dehumidifier seems a hassle with dripping water into a bucket. Haven't felt the need yet. Id say its a really good machine. Overall its quiet, no louder than a wall ac in a hotel. not the window ac type the one in hotels where the panel is against the wall. It will freeze you out if you set it that low, I try to get some longevity out of stuff so we keep it at about 79 and its perfect. I've set it down to 65 and it throws ice cubes. Its a heavy unit at 14000btu but its on wheels so its ez to move around. The kit to the window didn't fit in my window very well, so I went to the dollar store and bought a couple pool noodles to even out and seal better where the kit didn't. I did buy another exhaust kit so I didn't have to keep removing from the main room to the bed room window. It was a good solution for me. We are enjoying having this AC makes our summer home even more enjoyable. I have to use a blanket to sleep when normally I only use a sheet. Love that! If you need a AC this one works well.
