Reviews for 36,000 BTU 22.2 SEER2 ACiQ 4-Zone Ceiling Cassette Mini Split System Extreme Series - 9+12+18+18

Customer Reviews

Overall Ok

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).......

So far so good

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.

outstanding quality

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.

Amazing

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!

3rd system

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.

No complaints

No complaints from me. The process of identifying the type of system that I needed as well as the additional components that I wanted was very smooth and painless. I have used your site several times for finding and ordering mini split systems and each time has proven to be a simple process with quick delivery. Thanks!

No issues

Just finished installing my unit! It was easy and straight-forward. No issues at all!

My family and I are amazed the difference it has made! Our workshop is now a great place to be and work! Now our freezers and food supply doesn’t work near as hard and we can resume our freeze-dryer processes!

Thanks a million!

Superb

This system is superb. In a home built before the need for a/c; having no central ventilation system, I'm impressed with the ease of install, features and functions. This system is an absolute blessing.

The internet connected feature is phenomenal to control heat and cool on 5 units all at once.

Very satisfied and look forward to years of consistent heat and cooling throughout my home.

Very good

Initial impressions on the ACIQ mini split have been very good. I am a DIY homeowner but I am 608 certified so I installed the units myself. Installation was straightforward with no issues. I live in a log home and had reuse existing line sets due to not being able to access them without major demolition work. Line sets were thoroughly flushed and purged prior to triple evacuation. I did have to add about 3/4 lbs additional refrigerant due to the long length of the line sets. I am impressed with the units performance so far. I’m getting a 21 degree temperature difference supply vs return at the turbo fan setting. These units replaced a Carrier mini split system that never performed that well even when new. Loving the scheduling and other features of the mobile app to control the units. The inverter style condenser unit seems very efficient as far as amp draw. I really like how the fan speed will adjust to the outside ambient temperature for efficient heat extraction.

I chose the ACIQ system based on the warranty and online reviews having never seen the brand in person. I cannot yet vouch for the longevity of the units, but so far, I am completely satisfied.

Purchase went smoothly

My purchase went smoothly, had a couple of hiccups with delivery but nothing drastic. Since this was my first experience with installing a minisplit, the instructions on installing were very difficult to follow. Because of this it did take a little longer to figure out. The hvac tech that I had contacted took some time to get here so the unit wasn't charged until yesterday. So far, I am very happy with the product performance.

Great technical support

Great technical support! I believe the gentlemens name is Jim. Called twice with questions and he was helpful and very supportive. It’s all installed and working like a champ. We are off grid (batteries) and this unit doesn’t beat up or power supply to bad. Def got to be a sunny day to use
