-
Up to about 800 sq ft at average conditions. We size at about 22 BTU per sq ft, more conservative than the ENERGY STAR room-size chart. Add capacity for a hot climate, ceilings over 8 ft, strong sun (+10%), a kitchen (+4,000 BTU) or each person over two (+600 BTU). For a room-by-room load calculation, ask your installer for an ACCA Manual J. Not sure? Call (855) 775-4822 and we'll confirm the right size 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 18,000 BTU (1.5-ton). 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.
-
Rated SEER2 20.7 — 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 20.7) 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-RES18-230VO, CH-RH18MCT, CH-NPNL09-18CT. 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 items over $300 within the U.S., and our team can help with sizing and support.

What Stands Out
4-Way Ceiling Cassette
Recesses flush into the ceiling and pushes air in four directions for even, draft-free comfort across a 18000 BTU space — ideal where wall space is at a premium.
Inverter Efficiency — SEER2 20.7
A variable-speed inverter compressor ramps to match the load instead of cycling on/off, holding SEER2 20.7 on 230V — steady comfort with noticeably lower energy bills.
Right-Sized Coverage
Heats & cools up to about 800 sq ft at average conditions (about 22 BTU per sq ft).
