Cooper & Hunter / Ceiling Cassette PRO
Cooper Hunter Ceiling Cassette PRO 37k Hyper Ceiling Cassette 208/230V Mini-Split
The hyper light-commercial PRO cassette certifies at 36,600 BTU cooling and 37,000 heating, with 21.2 SEER2 and 10.6 HSPF2, rated to -22F.
This is one of the few places in the Cooper & Hunter range where the hyper unit is better on both axes - more efficient in cooling than the standard version as well as far more capable in the cold. If the building operates through winter, there is no real argument for the cheaper one.

Frequently asked questions
- Can I install the Cooper & Hunter Ceiling Cassette PRO 37,000 BTU R-454B 208/230V (CH-RSH36LCCT / CH-RHP36LCU-230VO) myself, or do I need a pro?
- Cooper & Hunter Ceiling Cassette PRO 37,000 BTU R-454B 208/230V (CH-RSH36LCCT / CH-RHP36LCU-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 Ceiling Cassette PRO 37,000 BTU R-454B 208/230V (CH-RSH36LCCT / CH-RHP36LCU-230VO) keep heating in a cold winter?
- The manufacturer publishes 37,000 BTU/h of heating output at 5F. Rated heating operation extends down to -22 F. Certified heating efficiency is 10.6 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 Ceiling Cassette PRO 37,000 BTU R-454B 208/230V (CH-RSH36LCCT / CH-RHP36LCU-230VO) need?
- Published electrical requirements: 230 V voltage, 38 A minimum circuit ampacity, and 40 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 Ceiling Cassette PRO 37,000 BTU R-454B 208/230V (CH-RSH36LCCT / CH-RHP36LCU-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.
