Reviews for 48,000 BTU ACIQ Extreme 23 SEER2 5 Zone Wall Mount Mini Split Heat Pump System - R454B | 230V - 6 + 6 + 12 + 12 + 18

Purchased and installed in 2022 - worked well for 2 years besides some minor noise and leakage issues. Then main circuit board broke and was told it was apparently due to us not installing a surge protector. Service/Warranty support was responsive but it took us about 2 months to finally resolve issue and had to replace board 2-3 times, costing us a lot in HVAC tech visits and had to install window AC units (as the minisplits went out during prime summer heatwave in DC). After it was fixed, we installed a surge protector, and hasn't recurred again (although we are nervous it will). Overall, I wish I had purchased a unit that local HVAC techs could have parts for same day (instead of having to wait for a week or two for replacement control boards to be shipped across country), but purchased this unit during COVID when supplies were limited during a renovation unfortunately. I also over the past 4 years have tried over 20 times to contact support/manufacturer to get replacement air filters for the 5 mini splits and have never been able to get anyone knowledgeable and get the replacements.....so normal parts service (outside of warranty service) is just non-existent......you'll just keep getting redirected to the https://hvacdirect.com/part-quote site, but I've never received a response from that site (and its often down).......

I got 2 wall units up and running last week and so far so good. They are keeping the main level at the desired temp in 20 degree outdoor weather. This week is supposed to get much colder so we'll see. I still have 2 more ceiling cassettes to put on this condenser, but they are going to be a lot more work.

Quality product. Much higher attention to detail than the Tosot unit it replaced. Very happy with purchase

I have not finished the install yet, but I am very impressed with the design of the system; I really liked the attention to details in the design; the little kickstand in the air handler that holds it out from the wall while you attach the lineset. The kickstand that holds up the wiring module. The locking bar that holds up the cover. priceless! And the performance specs are awesome I think. And the condenser area seems larger than the other one I put in 5 years ago that I can't remember; probably is why it is so efficient. Not excited that the refrigerant leak sensor in the handlers have to be replaced after 15 years, but I understand that is how things are and they probably won't cost much by then.

Doing great and just went through temperatures at -10. Heating was great and far better than the base board heat I had. My electric bills are down over 30% too!

I'm happy with the unit, everything going well with it so far.

Installed this system myself. Had to call tech support a few times to keep me on track, which was a big help.
Watched some generic youtube videos as well.
This system works great and is keeping g my 2500sqft home in Tahoe warm.

Prompt shipping, well protected from damage. Lowest price. Good customer support.

I really like this brand for mini split systems. they have a wide range of BTU's and how many units you can put on them.

Having a very large ranch house, I choose to install 3 separate outdoor units, and 10 indoor wall units.
Install went smoothly, all units performed as expected, looking forward to savings in utility bills, only time will tell.
