The Cooper & Hunter Hyper Heat Multi-Zone 3-Zone 19k (CH-RHP19M-230VO) is the cold-climate version of the three-zone Hyper, built to keep heating output up as temperatures fall. It posts a certified nominal SEER2 of 25, EER2 15, and HSPF2 10.4, and its heating holds essentially flat from 20000 BTU at 47F to 20000 at 17F and 19000 at 5F - real deep-cold capability, not a warm-day rating that collapses in 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.

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 3-Zone 19,000 BTU R-454B 208/230V (CH-RHP19M-230VO) myself, or do I need a pro?
Cooper & Hunter Hyper Heat Multi-Zone 3-Zone 19,000 BTU R-454B 208/230V (CH-RHP19M-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 3-Zone 19,000 BTU R-454B 208/230V (CH-RHP19M-230VO) keep heating in a cold winter?
The manufacturer publishes 19,000 BTU/h of heating output at 5F. Rated heating operation extends down to -22 F. Certified heating efficiency is 10.4 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 3-Zone 19,000 BTU R-454B 208/230V (CH-RHP19M-230VO) need?
Published electrical requirements: 230 V voltage, 17.5 A minimum circuit ampacity, and 20 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 196.8 ft, and the included line set comes pre-charged for 75 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 3-Zone 19,000 BTU R-454B 208/230V (CH-RHP19M-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.
