Cooper & Hunter / Ceiling Cassette
Cooper Hunter Ceiling Cassette 36k R-454B 208/230V Mini-Split
This is where the range crosses into light-commercial equipment: the CH-RH36LCCT cassette delivers 36,000 BTU of cooling and 38,000 of heating at 20 SEER2 and 10.3 HSPF2, rated to -13F.
At this size the install becomes a structural question rather than a mounting one. The head is large and heavy, it needs a substantial ceiling cavity, and the condensate and return-air paths have to be designed rather than improvised. Treat the equipment price as the smaller half of the project.

Frequently asked questions
- Can I install the Cooper & Hunter 4-Way Ceiling Cassette 36,000 BTU R-454B 208/230V (CH-RH36LCCT / CH-R36LCU-230VO) myself, or do I need a pro?
- Cooper & Hunter 4-Way Ceiling Cassette 36,000 BTU R-454B 208/230V (CH-RH36LCCT / CH-R36LCU-230VO) is built for professional installation: the line set must be flared, evacuated, and charged, which requires EPA-certified refrigerant handling. Installing it outside the manufacturer's requirements can void the warranty, so budget for a qualified HVAC installer.
- Will the Cooper & Hunter 4-Way Ceiling Cassette 36,000 BTU R-454B 208/230V (CH-RH36LCCT / CH-R36LCU-230VO) keep heating in a cold winter?
- The manufacturer publishes 26,600 BTU/h of heating output at 5F. Rated heating operation extends down to -13 F. Certified heating efficiency is 10.3 HSPF2. Match those numbers against your climate's design temperature - in cold regions, output at 5F matters far more than the nameplate capacity measured at 47F.
- What electrical circuit does the Cooper & Hunter 4-Way Ceiling Cassette 36,000 BTU R-454B 208/230V (CH-RH36LCCT / CH-R36LCU-230VO) need?
- Published electrical requirements: 230 V voltage, 33 A minimum circuit ampacity, and 35 A maximum breaker or fuse sizing. Confirm the final circuit against the unit nameplate and local code with a licensed electrician.
- How far can the outdoor unit be from the indoor head?
- The published maximum line-set length is 246 ft, and the included line set comes pre-charged for 25 ft. Longer runs than the included set allows typically mean added refrigerant and a pro visit, so measure the planned routing before ordering.
- What warranty does the Cooper & Hunter 4-Way Ceiling Cassette 36,000 BTU R-454B 208/230V (CH-RH36LCCT / CH-R36LCU-230VO) carry?
- The manufacturer publishes these warranty tiers: Standard: 5 yr parts / 7 yr compressor (licensed-technician installation and registration terms). Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
