If you want quiet operation, precise temperature control, and installation flexibility, an ACiQ mini split delivers all three, and if you would rather heat and cool with a single system, ACiQ heat pumps handle both jobs. We stock the brand across every major category because those priorities come up in nearly every project we help plan.

If you are still weighing a heat pump against a straight air conditioner, our heat pump vs air conditioner guide breaks down how each approach handles year-round comfort. Whichever direction your project takes, matched controls make a real difference, and ACiQ thermostats are purpose-built for the equipment on this page. You get a system designed to work as one, with our team ready to help you configure it.

Best ACiQ Systems for...

Single Rooms, Garages, and Additions

The best ACiQ mini split for a single room, garage, or addition is a wall unit sized to the space. The ACiQ 12,000 BTU Single Zone Wall Mounted Mini Split runs ductless and quiet.

Whole-Home Zoned Comfort

The best ACiQ system for whole-home zoned comfort is a multi-zone setup with independent room controls. The ACiQ 27,000 BTU 4-Zone Wall Mount Mini Split System conditions four areas from one condenser.

Ducted System Replacements

The best ACiQ option for replacing an aging ducted system is an inverter condenser that reuses existing ductwork. The ACiQ 3 Ton Central Heat Pump Inverter modulates output for steadier temperatures.

Hotels, Apartments, and Rentals

The best ACiQ choice for hotels, apartments, and rentals is a packaged terminal unit serving each space individually. The ACiQ 9,000 BTU PTAC Heat Pump fits a standard wall sleeve with backup electric heat.

FAQ

Are ACiQ mini splits good?

Yes. ACiQ mini splits combine inverter-driven compressors, efficiency ratings up to 27.4 SEER2, and WiFi-ready controls in wall-mount, ceiling cassette, floor-mount, and concealed duct styles. Reviewers consistently note quiet performance and straightforward installation across the lineup.

Do ACiQ heat pumps work in cold climates?

Yes. ACiQ Extreme Heat Series models maintain heating at outdoor temperatures as low as -22°F, so they can serve as a primary heat source in northern states. Standard models suit moderate winters, and dual-fuel pairings cover the harshest conditions.

What refrigerant do ACiQ systems use?

Most current ACiQ systems run on R454B, which carries a lower global warming potential than the R410A it replaces, while select models use R32. Our R-454B vs R-410A guide explains what the transition means for your purchase.

Can ACiQ mini splits heat and cool more than one room?

Yes. ACiQ multi-zone systems connect up to five indoor units to a single outdoor condenser, letting each area run its own temperature. Mix and match indoor styles per room, from wall units to ceiling cassettes, on the same system.

Who makes ACiQ?

ACiQ equipment is produced by one of the largest HVAC manufacturers in the United States, though the company keeps that manufacturer's name confidential. The arrangement lets ACiQ pair proven engineering with accessible pricing, which is why the brand has grown so quickly in recent years.
