abunda_amazon_reviews My experience is quite different than a lot of people. My unit worked fine through most of the first summer. When springtime came around this year even with the cooler temps , when a moderately warm day. low 80's came around it would work fine for a couple of hours then proceed to ice up. Our installer came several times putting freon in , checking all of those hoses for leaks and pretty much every other thing he could think of. Never go it running right. So he called the manufacturer and was told that the unit of mine was meant for a smaller area. My installer, who has been in the business for several years diagreed with them saying my unit could handle the area cooled and them some. Now I am stuck with a pretty looking unit that won't do it's job as the manufacturer will not stand by it's product Pioneer sucks !;;Reviewed in the United States on July 8, 2018;;2.0 out of 5 stars;;My unit worked fine through most of the first summer;;Stephen Hirsch;;;I had so much troubles with this item I ordered from HIGHSEER. Altogether, it had taken me almost 10 weeks long to finally have the A/C system works as expected. So, from my experience, i hope it would help you guys to do a thorough test with the unit upon finish installing the A/C system to make sure everything is working and not have to go through what I had gone through. First, the original shipment they sent out somehow were lost, and they didn't even follow up with me about it. I waited for over 3 weeks and did not receive it, then i called them and found out the package somehow was lost during transist, which result me losing an additional $100 to reschedule my A/C guy for the installation. After that they ship out a new package, I received the new package about a week later, which makes it almost a month later since I made the order. (Ordered on May 25, 2017 and received the unit on June 23rd,2017). Secondly, we had the A/C unit installed a week later by a professional A/C installer and did some simple tests and it was running fine on first use (basically, only turned it on and made sure it was cold and had the unit blowing out really strong airflow). 4 days later, we tried to use the A/C on a hot day, the wall unit's fan would not run at all when we turned on the unit, and after about 30 seconds, we get an "E3" error on the wall display panel (reset the unit several times and still same issue). So then, I emailed the seller about it and they send me a video to watch & follow to figure out what's wrong. After a while playing with their debuging steps, i found out that to avoid getting the "E3" error, I had to use a chopstick and manually push the internal fan on the wall unit (right after I turned it on) to help the fan moves and then it starts to work (and literally i had to do that everytime I turned it on for about 5 weeks). I reported what i found back to the seller and they said it was probably a bad indoor controller board (PCB) or a bad internal fan motor. and they were going to send out those replacement parts the next day and I would received it in a week. However, I did not receive those replacement parts for almost 3 weeks later. During those weeks that I waited for the parts, I also found out that NONE of the other functions of the A/C system were working (timer, sleep mode, fan speed - it was always blowing at highest speed and was extremely loud, etc...) The only thing worked was either cold or hot air coming out (with the help of the chopstick). Anyway, after I received those replacement parts, with the help of Erik (from HIGHSEER) to guide me through the process of switching them out. Took me about 4, 5 hours back & forth with him through emails and I still couldn't get it to work. That was when Erik decided to send me an entire new wall unit. Took me another week to receive the unit, and waited a week for the A/C installer to have an open slot on his schedule to come by and switch out the defective one for me (btw, he charged me another $200 for the works.). Amazingly, the new unit had no problems at all, everything is working, and it's super quiet. So anyway, like i said, it had taken me almost 10 weeks long with lot of back & forth emails and an extra $250 in installation fees to have a perfect working A/C system. Once, it's working, I really like the system but with all the headaches I had to deal with and extra money I had to spend, I had to give it a 2 stars for this review, otherwise I would had given it a 5 stars review. Btw, I'm not trying to give the seller a bad rep, these guys were very responsive and helpful (especially, Erik) but because of all the troubles with my order & my unit, I just have to share about it. Maybe it was just my luck or maybe they need to do better QA on the unit before shipping it out to customers. update 02/19/2019: the A/C been working fine for a little over a year now, however, the outside unit (condenser) started making loud revving sounds (like when you floor your car's gas pedal), and it gets very very loud and since the condenser is right outside my bedroom, I could feel it vibrating the wall at night. I'm not sure if this is normal and this is a sign of it going bad. This behavior started since last month, and i'm using "Heat" mode right now. Crossing my fingers that it's not sign of problems coming... Update 7/16/19: unit is still running, but i think the temperature control for the cold A/C is not functioning correctly anymore. Doesn't matter if I set Cool at 70 degrees or 80 degrees, the cold air coming out from the vent is freezing... which making it very cold for us if we leave A/C run through out the night now. So to work around, we just use the timer function and have it turn off after 2 hours... Looks like this will not last very long now that just within 3 years, there are majors issues happening already.;;Reviewed in the United States on August 20, 2017;;2.0 out of 5 stars;;Went thru a lot of troubles to get this A/C unit installed and working properly.;;Brandon;;;I have had it running for a few days. I bought the 12K and 24K units. If you are thinking about doing it yourself its possible but it wasn't as easy as some reviewers say. Perhaps the next time I do it I will say differently. What took me the most time is the electrical since I had to go across the house and put a sub-panel in. I have done that before but fishing wires and mounting and cutting conduit just takes time so remember that. I was completely paranoid about the vacuum part but honestly that was the easiest part. The hardest part of the process is bending the lines and cutting them to length to make a nice looking install. Sure I would have just hung the coils out of the wall and called it day but to make it nice you really need to do some bending and cutting, at least in my situation. I had my brother-in-law come for the bending/cutting/vac part (he is a tech) so he could teach me and I am so happy he did. It gave me peace of mind. I could have done it without him but if you have someone who can guide you on your first time then call them. The product seems awesome, it came with literally everything needed and the instructions are very good. What you will need is a pipe cutter, flaring tool, torque wrench (if you want to go by the book) and crows fittings for your lineset size, crescent wrenches, nylog (though it does come with lineset sealant I wanted the good stuff), some sort of mounting pad, cement blocks (to raise it off the mounting pad),pipe bender for sharp bends (we did ours slowly all by hand because I bought the wrong size), vacuum pump (go 5cfm or higher for longer length), manifold gauges, micrometer (for the sticklers I am told), nitrogen to pressure test and the regulator for it (I was going to skip this part but my brother-in-law brought it with him so we did it), all the electrical equipment like volt meter, conduit, breakers, wires, etc. Its a long list as you can see so this should serve as a warning to the complexity of the project. Last thing, you need to raise it off the pad, as it comes its too low and the outside drain section hits the ground (used in heat mode), hence the cement bricks. If I were to do it again I would probably just get a snow stand. I am glad I did it but take your time, it's certainly not an easy project but it's a doable one if you are motivated.

Anyway, after I received those replacement parts, with the help of Erik (from HIGHSEER) to guide me through the process of switching them out. Took me about 4, 5 hours back & forth with him through emails and I still couldn't get it to work. That was when Erik decided to send me an entire new wall unit. Took me another week to receive the unit, and waited a week for the A/C installer to have an open slot on his schedule to come by and switch out the defective one for me (btw, he charged me another $200 for the works.). Amazingly, the new unit had no problems at all, everything is working, and it's super quiet. So anyway, like i said, it had taken me almost 10 weeks long with lot of back & forth emails and an extra $250 in installation fees to have a perfect working A/C system. Once, it's working, I really like the system but with all the headaches I had to deal with and extra money I had to spend, I had to give it a 2 stars for this review, otherwise I would had given it a 5 stars review. Btw, I'm not trying to give the seller a bad rep, these guys were very responsive and helpful (especially, Erik) but because of all the troubles with my order & my unit, I just have to share about it. Maybe it was just my luck or maybe they need to do better QA on the unit before shipping it out to customers. update 02/19/2019: the A/C been working fine for a little over a year now, however, the outside unit (condenser) started making loud revving sounds (like when you floor your car's gas pedal), and it gets very very loud and since the condenser is right outside my bedroom, I could feel it vibrating the wall at night. I'm not sure if this is normal and this is a sign of it going bad. This behavior started since last month, and i'm using "Heat" mode right now. Crossing my fingers that it's not sign of problems coming... Update 7/16/19: unit is still running, but i think the temperature control for the cold A/C is not functioning correctly anymore. Doesn't matter if I set Cool at 70 degrees or 80 degrees, the cold air coming out from the vent is freezing... which making it very cold for us if we leave A/C run through out the night now. So to work around, we just use the timer function and have it turn off after 2 hours... Looks like this will not last very long now that just within 3 years, there are majors issues happening already.

4.0 out of 5 stars

Great kit, had almost everything needed to install except the tools. Is performing well in the rooms I installed them in.
I have had it running for a few days. I bought the 12K and 24K units. If you are thinking about doing it yourself its possible but it wasn't as easy as some reviewers say. Perhaps the next time I do it I will say differently. What took me the most time is the electrical since I had to go across the house and put a sub-panel in. I have done that before but fishing wires and mounting and cutting conduit just takes time so remember that. I was completely paranoid about the vacuum part but honestly that was the easiest part. The hardest part of the process is bending the lines and cutting them to length to make a nice looking install. Sure I would have just hung the coils out of the wall and called it day but to make it nice you really need to do some bending and cutting, at least in my situation. I had my brother-in-law come for the bending/cutting/vac part (he is a tech) so he could teach me and I am so happy he did. It gave me peace of mind. I could have done it without him but if you have someone who can guide you on your first time then call them. The product seems awesome, it came with literally everything needed and the instructions are very good. What you will need is a pipe cutter, flaring tool, torque wrench (if you want to go by the book) and crows fittings for your lineset size, crescent wrenches, nylog (though it does come with lineset sealant I wanted the good stuff), some sort of mounting pad, cement blocks (to raise it off the mounting pad),pipe bender for sharp bends (we did ours slowly all by hand because I bought the wrong size), vacuum pump (go 5cfm or higher for longer length), manifold gauges, micrometer (for the sticklers I am told), nitrogen to pressure test and the regulator for it (I was going to skip this part but my brother-in-law brought it with him so we did it), all the electrical equipment like volt meter, conduit, breakers, wires, etc. Its a long list as you can see so this should serve as a warning to the complexity of the project. Last thing, you need to raise it off the pad, as it comes its too low and the outside drain section hits the ground (used in heat mode), hence the cement bricks. If I were to do it again I would probably just get a snow stand. I am glad I did it but take your time, it's certainly not an easy project but it's a doable one if you are motivated. With the tools I saved around 8K over what installers around here wanted for these two rooms (family room and basement exercise studio)
