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.
Does it heat as well as cool?
Yes — it is an inverter heat pump that both cools and heats. See the specifications for this model’s heating range.
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).
