Does this work on its own?
No. An indoor head needs a matching outdoor unit from the approved list above. If you are replacing one head on an existing multi-zone system, match the series and refrigerant of the outdoor unit you already have.
Can I install it myself?
Mounting, wiring and running the line set are within reach of a capable DIYer. The refrigerant connection and vacuum should be done by a licensed HVAC technician in most states, and manufacturer warranties usually require it. We can point you to an installer in your area.
What if I am not sure about the size?
Room size, ceiling height, insulation, windows and sun exposure all change the answer. Call (417) 812-0015 with the room details and we will confirm the BTU rating before you order.
Can I return it?
No. All sales are final, so size it right first: the builder and the sizing guide are free, and a person confirms the pairing on every order. If anything arrives damaged, we handle the claim for you, and defects are covered by the manufacturer warranty.
What refrigerant does it use?
R454B. Match it to any existing equipment or line set you plan to reuse; refrigerants are not interchangeable.
