Wait! This is an Individual Component To build a working system, this unit must match your other equipment in two ways:

  • Same Brand Only: Only pair with other same Brand and Series.
  • Same Refrigerant: Both units must use the exact same gas type (R454B, R32, or R410A).

Mixing different brands or refrigerant types will cause the system to fail and void your warranty.

Questions about this system?

Answers in seconds — tap a question below

  • Sized for about the room's square footage at ~20 BTU per sq ft. Rule of thumb: ~20 BTU per sq ft, and 12,000 BTU = 1 ton (this unit is 12,000 BTU). Ceiling height, insulation, sun and climate shift that — if you're between sizes, size up for hot/humid rooms. Not sure? We'll confirm the right BTU for your space.
  • 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 12,000 BTU. BTU tells you the capacity; SEER2 tells you the efficiency.
  • It uses R454B — the newest low-GWP eco refrigerant, so it's future-proof and efficient. 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.
  • 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 compressor) 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 — WiFi is 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-RLS12MIA-230VO. 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

Sleek Wall-Mount Design

A slim, quiet indoor head mounts high on the wall of MIA-series heating & cooling — modern looks with whisper-quiet operation.

Smart Wi-Fi Control

Wi-Fi is included — set schedules and adjust the temperature from your phone anywhere, or pair with Alexa & Google Home.

Year-Round Heat Pump

One system that cools in summer and heats in winter — reliable Cooper & Hunter performance in every season.

Cooper&Hunter Outdoor Condenser

The outdoor condenser is the core of a ductless system: it houses the inverter compressor, the heat exchanger and the fan that reject heat in cooling and absorb it in heating. This listing is the condenser as a single component — for replacing a failed outdoor unit or building a system to your own specification.

It runs on R454B, the low-GWP refrigerant that replaces R410A in new equipment, and pairs with Cooper&Hunter indoor units of matching capacity and voltage. A corrosion-protected cabinet, inverter operation and a wide ambient range suit residential and light commercial installations.

Warranty and Tech Support Info

Model CH-RLS12MIA-230VO

By selecting Cooper&Hunter products for your home or business, you’ll receive expert technical support from heating and cooling specialists, including product manuals, troubleshooting guides and warranty information.

Warranty terms: the manufacturer provides a Limited Warranty of 7 years for the compressor and 5 years for parts.

Energy Efficiency

Energy Efficiency

Cooper&Hunter’s Inverter Technology maximizes efficiency and reduces energy costs by adjusting the compressor speed to your specific needs. Experience unparalleled comfort, quieter operation, and longer equipment lifespan. Choose Cooper&Hunter for cutting-edge HVAC solutions that deliver optimal performance and reliability.

Main Features

An inverter-driven compressor modulates capacity instead of cycling on and off, which holds temperature steadier and cuts running cost. The cabinet is finished for outdoor exposure, and the heat exchanger is sized for year-round heat-pump duty, not cooling alone.

Because the condenser is sold on its own, you match it to the exact indoor configuration you need — replacement, retrofit or a custom build — without paying for parts you already have.

Frequently Asked Questions

Is this a complete system or just the outdoor condenser?

This listing is the outdoor condenser only. The Cooper & Hunter MIA 12,000 BTU outdoor condenser is sold as a single component for replacements and custom builds, so it does not include the indoor unit, line set or installation kit. Order the matching components separately if you are building a full system.

Which units is the Cooper & Hunter MIA 12,000 BTU compatible with?

It pairs with Cooper & Hunter R454B equipment of the same refrigerant and voltage — R454B, 230V. Match the total indoor capacity to this condenser's rating, and keep the refrigerant identical: R454B components cannot be mixed with R410A.

What line set size does it use?

Copper line size is 1/4"/3/8" (liquid/gas). Use the same diameters on the matching component, and keep the run within the manufacturer's maximum length.

Does it come pre-charged with refrigerant?

Yes — it ships pre-charged with R454B for line sets up to 25 ft. Longer runs need additional refrigerant added by a licensed technician.

Do I need a licensed technician to install the Cooper & Hunter MIA 12,000 BTU?

Yes. Connecting refrigerant lines requires EPA 608 certification in the United States, and correct evacuation and charging are what keep the rated efficiency and the factory warranty intact.
