I had bought a portable A/C a couple of years ago and loved it. It still works, but I wanted to get one with heat on it as well. This one is 200% better than the last one I bought. The low setting creates such an air flow that I'm almost afraid to put it on high. It cools great, easy to use with it's remote control. It circulates the air much better with it's sweeping motion on the blades. It is a little noisy, as are most A/Cs but not an uncomfortable amount of noise, I just have to turn the volume up on the television a bit. Cools my open floor plan kitchen, dining room and living room with no issues at all. It's still to warm in Texas to kick on the heater, but it will be a nice addition this winter.

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.

I bought this AC/Unit / Heater in February 2022 for my man cave area of the home. At first everything worked great. Heat was warm and A/C was ice cold with absolutely zero issues. To be honest this is a very simple device that is easy to setup and use. Instructions are simple. I was to preface this also stating this unit was NOT heavily used. The noise level is moderate (it is not quiet) but can be tolerated by turning up the TV or surround sound. I did not expect it to be super quiet so this is not an issue. What was an issue is that at the end of July 2022, It stopped working. AC was luke warm at best in the middle of the a Southern US summer. At first I was just going to toss it out and be out 400+ bucks or whatever I paid at that time. Instead I told me wife let’s see about this warranty which I turned over to her to deal with. At the end of July my wife called the company to request warranty assistance via a number found for them on google. She was able to get ahold of somebody who stated that a claim was submitted and we would receive an email within 24-48hrs. We did receive a complaint ticket # or reference number for this call. After 3 days we received no response or email and yes we checked junk mail. My wife called them again and asked what the status was and again was told she would receive an email within 24-48hrs. After 48hrs we again had no response so my wife called them again and was told again we would have an email within 24-48hrs. She used the complaint reference number each time she called. After the 3rd callback she received an email within 24hrs asking if we did all the simple things the directions said to ensure it was broken. Things such as unplug it, clean filters, drain it etc., basically easy stuff I checked 17 times before giving up. My wife emailed back and forth with the representative whom did state that it was covered and they would be sending us a new unit. We had to send them a copy of our Amazon receipt which is totally understandable. Once the new unit shipped we had it within a week. Since that time for the small amount I have used it… it is functioning perfectly. I did plug the old unit back in just to see if the heat function at least worked on it since the AC didn’t but that also did not work. So to wrap up. When the unit is working it does work as expected, it looks nice and is easy to use. The jury is still out for me on the overall quality as I’m on my second unit. The warranty is there but will require some work to get it. I still have the old unit which I will now have to take to a dump or recycle center. I realize things break unexpectedly sometimes and I am glad I didn’t have to shell out another large sum of money on a different brand. We also have a second serine life smaller A/C only unit that has worked for one summer thus far. I am going to have to see how this unit works over the winter of 2022 / Summer of 2023 to fully know if I would buy from them again. I hope this helps somebody on the fence in some way.

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.

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
