- Is 18,000 BTU enough for two rooms?
- It depends on room size and insulation. Split across two heads, each zone gets roughly 9,000 BTU, which suits a small bedroom or office but not a large open living area.
- Can I really install this myself?
- You can mount the indoor and outdoor units and run the pre-charged line set, but refrigerant connections and the final vacuum usually need a licensed HVAC tech. Skipping that step can void the warranty.
- Does it heat in winter?
- Yes, it is a heat pump and heats as well as cools. Output drops as outdoor temperatures fall well below freezing, so it is best in mild to moderate climates.
- How many remotes are included?
- It comes with a remote for the system, and each zone can be set separately. Check the box contents for whether one or two remotes ship.
- How does it compare with Mitsubishi or Daikin?
- Those brands have deeper service networks and stronger cold-climate ratings. Stealth competes on DIY-friendly installation and two-zone flexibility at a lower installed effort.
- Does it need a dedicated electrical circuit?
- Yes, a mini split of this size needs its own circuit, typically 240V. Have an electrician confirm your panel can support it before buying.
