Frequently asked questions.
What's included in this system?
A complete single-zone system: the indoor unit and its matching outdoor condenser. Choose a line-set kit length at checkout, or supply your own.
What size room does it suit?
It is rated at 18,000 BTU — size it to your room’s square footage and insulation for the best match.
Does it heat as well as cool?
Yes — it is an inverter heat pump that both cools and heats down to -22°F outdoor ambient (Hyper Heat). See the specifications for this model’s heating range.
What refrigerant does it use?
R454B. The system ships factory pre-charged; a licensed installer adjusts the charge for your line length.
Who should install it?
A licensed HVAC professional — required for the refrigerant, electrical, and startup work, and to keep the manufacturer warranty valid. Many customers buy the equipment here and hire a local installer.
What warranty does it come with?
Cooper & Hunter backs it with a 7-year compressor and 5-year parts limited warranty (with professional installation and registration).
