I had this mini split installed by a licensed HVAC tech in April of 2023 and was maintained. It worked great for the time that it worked. Here is the issue. It's stopped working in November of 2024. So it worked for a year and half with no issue. I had the same HVAC tech come out to check it out. He spent about 5-6 hours trying to trouble shoot it, because it wasn't throwing any codes, then trying to connect with their customer service. By the end, they suggested new sensors that was covered under warranty. So a week later I get them and the tech installs new sensors. Still no luck. He spends another 2-3 hours with their customer service, for them to send a PCB board covered under warranty. 2 weeks go by, and I get it, same tech comes out spends 3 hours, still not working. He contacted the customer service and warranty center, and now we are almost positive that the compressor is bad. Which has been a week and I still haven't gotten it. So not 100% yet that it will solve the issue.Here is my issue with all of this.1. Yes all parts have been sent free of charge under the warranty, however, the new compressor means new refrigerant, which can cost several hundred dollars. So they send me a new compressor, but I have to pay several hundred dollars for new refrigerant for it to possibly fix my issue.2. Guess what isn't covered under the warranty. LABOR COST. My tech charges $85 an hour for his time. Adding up his hours, and refrigerant costs, I'm going to be spending likely $1500+ JUST TO GET IT WORKING AGAIN. That is more than I paid for the whole unit!3. It stopped working the end of November, and it is now almost mid-January, and through the back and forth parts and shipping time, it's still not working. In the middle of winter, when the heat is needed.I am HIGHLY disappointed, and will swear to anyone to never buy anything from Pioneer just because of this experience. My HVAC tech, who has installed many of these, said he likely will stop purchasing and installing these, because of this experience.If they reach out to me and make something right with the labor costs, I will gladly adjust my review, since while it worked, it worked great, but there is no excuse for this ridiculous so far.

Love this mini split! Had it professionally installed in my 2.5 car garage and it works like a charm. Super efficient and run it almost 24/7 with very very little increase to the electric bill. Run it all the time to keep low humidity in the garage and provide comfort for my man space. Total cost was $2,500 installation included. That was one half the cost the local HVAC were quoting. Good purchase.

This review is for the 220V 18000btu Diamante Ultra system. I just finished the installation so long term reliability and efficiency are not known. The install was not easy due to the need to run the lines around sharp bends and corners. [But, very much worth doing.] The system is very quiet and cools the room thoroughly in a very short time. Once the set temperature is reached, the system is nearly silent. Even the outside unit is quiet. The remote is easy to use and setting the various functions is easy. The unit comes with nearly everything I needed to install. I did need to cut and braze elbows in the 1/2" line in 3 places because of tight turns that were necessary for keeping the routing neat. The electrical supply is also not included. only the wires that connect the indoor/outdoor units comes in the kit. I also used a vacuum pump and gauges to leak-check and finish the line install. Overall, I would recommend this system highly.
