The Cooper & Hunter Hyper Heat Multi-Zone 5-Zone 36k (CH-RHP36M-230VO) is the cold-climate flagship, running five heads on one 208/230V outdoor unit while keeping heating strong in deep cold. It posts a certified nominal SEER2 of 23, EER2 13, and HSPF2 10.7 - the highest HSPF2 in this group - and its heating rises from 36000 BTU at 47F to 38000 at 17F before returning to 36000 at 5F, output at or above its 47F rating well into winter.

It uses current low-GWP R-454B refrigerant, is ENERGY STAR certified, and is AHRI cold-climate designated. Cooper & Hunter is a value-focused ductless brand that delivers high-efficiency inverter multi-zone below the premium names; professional installation required and units are dealer-quoted.

Certification: ENERGY STAR certified, ENERGY STAR cold-climate certified and AHRI cold-climate designated. Refrigerant: current low-GWP R-454B. Minimum heating ambient: -22 F.

Strengths

  • Heating rises in the cold: 36000 BTU at 47F climbs to 38000 at 17F, then 36000 at 5F.
  • Certified nominal SEER2 23 / EER2 13 / HSPF2 10.7 - the highest HSPF2 here.
  • Current low-GWP R-454B refrigerant, ENERGY STAR certified, AHRI cold-climate designated.
  • Whole-home five-zone coverage with genuine deep-cold performance at a value price.

Weaknesses

  • Sits a notch below top premium brands on brand cachet and dealer network.
  • 36,000 BTU across five zones is modest per room; size each head carefully.

Sizing note: do not just add up the rooms. Multi-zone condensers have a maximum total connected capacity, and connecting more head capacity than the unit is rated for is a common installer mistake that hurts efficiency and comfort. Match total head capacity to the condenser's rating.

Frequently asked questions

Can I install the Cooper & Hunter Hyper Heat Multi-Zone 5-Zone 36,000 BTU R-454B 208/230V (CH-RHP36M-230VO) myself, or do I need a pro?
Cooper & Hunter Hyper Heat Multi-Zone 5-Zone 36,000 BTU R-454B 208/230V (CH-RHP36M-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 Hyper Heat Multi-Zone 5-Zone 36,000 BTU R-454B 208/230V (CH-RHP36M-230VO) keep heating in a cold winter?
The manufacturer publishes 36,000 BTU/h of heating output at 5F. Rated heating operation extends down to -22 F. Certified heating efficiency is 10.7 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 Hyper Heat Multi-Zone 5-Zone 36,000 BTU R-454B 208/230V (CH-RHP36M-230VO) need?
Published electrical requirements: 230 V voltage, 37 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 262.4 ft, and the included line set comes pre-charged for 125 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 Hyper Heat Multi-Zone 5-Zone 36,000 BTU R-454B 208/230V (CH-RHP36M-230VO) carry?
The manufacturer publishes these warranty tiers: Standard: 5 yr parts / 7 yr compressor (standard registration/installation terms). Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
