This C&H 5-zone package lets you independently control the climate in five separate rooms from a single outdoor unit. The base package includes one C&H multi-zone outdoor unit (rated to -13°F) and five indoor wall-mount units with remotes and built-in Wi-Fi. Using the dropdown menus on this listing, you can upgrade the outdoor unit to a larger capacity (36K, 48K, or 60K BTU) and choose from ten different indoor unit styles — wall mounts, floor consoles, floor/ceiling units, slim ducted, 4-way cassettes, 1-way slim cassettes, and central air handlers.
System efficiency: 24 SEER2, 12 EER, 9.5 HSPF2 — Energy Star certified. Uses R454B refrigerant. The outdoor unit features gold-coated coils, basepan heater, refrigerant leak detection, and high-frequency racer technology for 6-second startup. Indoor units include Wi-Fi control, remotes, auto-restart, and basepan heater. Important: total indoor BTU combined must not exceed the outdoor unit's rated capacity.

Frequently Asked Questions
How do I choose which outdoor unit size I need?
Add up the BTU of all five indoor units you're selecting. That total must not exceed the outdoor unit's rated capacity. For example: five 9K indoor units = 45K total → you need the 48K or 60K outdoor unit. The 36K outdoor can handle up to five zones as long as combined BTU doesn't exceed 36K (e.g., five 6K or 7K zones). See each outdoor unit's Allowed Combinations chart for specific pairing rules.
Can I mix different indoor unit types on the same outdoor unit?
Yes — you can mix wall mounts, cassettes, floor consoles, slim ducts, and air handlers on a single outdoor unit. The only restriction is that if you use two Central AHU units, no other indoor types can be added to that outdoor unit, regardless of remaining BTU capacity. Check the Allowed Combinations chart for any other pairing restrictions.
Do all indoor units include Wi-Fi and a remote?
Wall-mount units (Olivia, Olivia Midnight, Astoria, Astoria Pro) include Wi-Fi and a remote. Floor consoles, cassettes, and slim ducted units include remotes; some include Wi-Fi (check the cut sheet for the specific model). Central AHU units use a 24V wired thermostat interface and do not include a remote — they work with standard compatible wired thermostats.
Does this system require warranty registration?
Yes — Cooper & Hunter requires warranty registration to activate the full 7-year compressor and 5-year parts warranty. Registration can be completed at cooperandhunter.us/warranty. Failure to register may limit coverage to standard non-registered terms. Complete registration within 60 days of installation.
