Questions about this system?
Answers in seconds — tap a question below
-
Covers about the combined area of its rooms, 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 19.0 — 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 19.0) 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 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-12MASTWM-230VI, CH-12MASTWM-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.
Important info
- R-410A is being phased down in favor of newer refrigerants; inventory is limited.
- Existing R-410A systems remain serviceable; parts and qualified service are widely available.
- Check local codes and rebates. Some incentives prioritize high-efficiency heat pumps (R-32/R-454B).
- We stock both R-410A and next-gen options—choose what fits your timeline and budget.

What Stands Out
Complete 2-Zone System
Heat or cool 2 rooms independently from one 18000 BTU Astoria outdoor unit (12K+12K) — every zone sets its own temperature, delivered by wall mount indoor units.
Inverter Efficiency — SEER2 19
A variable-speed inverter compressor ramps to match the load instead of cycling on/off, holding SEER2 19 on 230V — steady comfort with noticeably lower energy bills.
Smart Wi-Fi Control
Wi-Fi is included — set schedules and adjust the temperature from your phone anywhere, or pair with Alexa & Google Home.
