ACiQ mini split FAQs

Is ACiQ a good mini split brand?

ACiQ Essentials systems carry AHRI certificates, use R32 refrigerant, include built-in WiFi, and come with a 6-year compressor and 4-year parts warranty when registered online. The 2-zone systems are ENERGY STAR certified. Specs, manuals and AHRI certificates are linked on each product page so you can compare before you buy.

What size ACiQ mini split do I need?

As a starting point: 9,000 BTU for up to about 400 sq ft, 12,000 BTU for up to 600 sq ft, 18,000 BTU for up to 1,000 sq ft, 24,000 BTU for up to 1,500 sq ft and 36,000 BTU for up to 2,000 sq ft. Insulation, ceiling height, windows and climate change the answer, so confirm with a load calculation.

What is the difference between the 17 SEER2 and 20 SEER2 models?

The 20 SEER2 models are more efficient, are rated at their full nominal BTU, and keep heating down to -4°F instead of 5°F. The 17 SEER2 models cost less up front. On every size, the 17 SEER2 versions are rated slightly below their nominal capacity (for example, 11,500 BTU on the 12K and 23,000 BTU cooling on the 24K).

Are there 115V ACiQ mini splits?

Yes. The 9,000 BTU 20 SEER2, 12,000 BTU 17 SEER2 and 12,000 BTU 20 SEER2 systems come in 115V and 208/230V versions. The larger systems are 208/230V. Compare them with Senville's 115V models in our 110V mini split collection.

Can one ACiQ system heat and cool two rooms?

Yes. The 18,000 BTU (22 SEER2) and 24,000 BTU (23 SEER2) 2-zone systems run two wall-mount indoor units from one outdoor unit, and each room gets its own temperature control.

Can I install an ACiQ mini split myself?

Installation involves refrigerant connections and high-voltage wiring, so plan on a licensed HVAC technician, and check whether your area needs a permit.
