Questions about this system?

Answers in seconds — tap a question below

  • Covers about 500–800 sq ft total, split across its indoor units — each head handles its own room, so you put the right capacity where you need it. Rule of thumb: ~20 BTU per sq ft, and 12,000 BTU = 1 ton (this system is 18,000 BTU (1.5-ton)). Want help splitting the zones? Our team can map it out.
  • 12,000 BTU = 1 ton — "tons" is just the older way of stating capacity. So 24,000 BTU = 2 tons, 36,000 = 3 tons, and so on. This system is 18,000 BTU (1.5-ton). BTU tells you the capacity; SEER2 tells you the efficiency.
  • It uses R410A — a proven, widely serviced refrigerant. The outdoor unit ships pre-charged for a standard line set, so most installs need no extra refrigerant; your licensed, EPA-608-certified installer verifies the charge and tops it off if your line set is longer.
  • Rated SEER2 22.9 — a strong efficiency number, and the higher it is the lower your energy bills. Its inverter compressor ramps up and down instead of cycling on/off, so it holds the temperature steadily, runs quietly, and uses less power than a standard AC or window unit.
  • Needs a dedicated 230V circuit, like a large household appliance, so it can deliver full capacity to larger rooms and multi-zone setups. Your licensed HVAC installer or electrician sets up the correct breaker and disconnect to meet local electrical code.
  • Yes — a big upgrade. It's far more efficient (inverter, SEER2 22.9) and much quieter, since the compressor sits outside instead of in your window or on the floor. It mounts permanently, doesn't block a window, and heats as well as cools year-round. Higher upfront cost, but lower bills and a longer lifespan.
  • Yes to all three. It's an inverter heat pump — cools in summer, heats in winter (even in the cold), far more efficiently than electric heaters. A Dry mode also pulls out humidity, so rooms feel cooler and less muggy.
  • Yes. Each indoor unit has its own remote/thermostat — set different temperatures or turn one off, so you only condition the rooms you use and save energy on the ones you're not. One outdoor unit powers them all, keeping install and running costs lower than separate systems per room.
  • Yes — WiFi is not included, so you can set schedules, change the temperature, and even turn it on before you get home, all from the mobile app (and pair it with voice assistants). A standard remote is included too.
  • Ships as a complete set: CH-18MES-230VO, CH-B06MOLVWM-230VI, CH-B06MOLVWM-230VI. Everything arrives together — check the photos and specs for the full kit.
  • It should be installed by a licensed, EPA-608-certified HVAC professional — we don't recommend DIY installation. Handling refrigerant requires EPA Section 608 certification under U.S. law, and professional installation keeps the system safe, code-compliant, and your manufacturer warranty valid.
  • Yes — you get full inverter heat-pump technology and the same core features as premium brands without paying for the name, which is how we keep prices low. Shipping is free on U.S. orders over $300, and our team can help with sizing and support.

What Stands Out

Complete 2-Zone System

Inverter Efficiency — SEER2 22.9

A variable-speed inverter compressor ramps to match the load instead of cycling on/off, holding SEER2 22.9 on 230V — steady comfort with noticeably lower energy bills.

Right-Sized Coverage

Engineered to heat & cool up to 500–800 sq ft across 2 zones — matched capacity so you never over- or under-size the space.

Frequently Asked Questions

How many rooms can the Cooper & Hunter 2 Zone 18,000 BTU system cool?

The Cooper & Hunter 2 Zone 18,000 BTU mini split system can effectively cool two rooms, with a total coverage area of up to 850 sq ft. This setup allows for flexible installation in different areas of your home.

Can I mix BTU sizes with the Cooper & Hunter mini split system?

Yes, you can mix BTU sizes with the Cooper & Hunter mini split system as long as the total BTU does not exceed the maximum capacity of the outdoor unit. For example, you could pair a 12,000 BTU indoor unit with the 18,000 BTU outdoor unit for optimal performance.

Do all zones run simultaneously in the Cooper & Hunter multi-zone system?

In the Cooper & Hunter multi-zone system, both zones can run simultaneously, allowing you to maintain different temperatures in separate areas. This flexibility is ideal for tailored comfort throughout your home.

Is it more efficient to use a multi-zone mini split like Cooper & Hunter instead of multiple single-zone units?

Using the Cooper & Hunter 2 Zone 18,000 BTU mini split system is often more efficient than multiple single-zone units due to its higher SEER rating of 22.9, which enhances energy savings. This efficiency can lead to lower utility bills while providing targeted comfort.
