Our take on the Stealth DIYCOOL 18,000 BTU 2 Zone Wall Mount Mini Split Heat Pump System

The Stealth DIYCOOL is a two-zone ductless mini split heat pump with 18,000 BTU of total cooling and heating, aimed at garages, additions and small apartments where ductwork is not an option. It ships with two wall-mounted indoor heads, a remote and a pre-charged line set, so a handy homeowner can do much of the install before an HVAC tech handles the refrigerant lines. That DIY angle is its main edge over brands like Mitsubishi and Daikin, which generally require a licensed installer. Reviewers like the quiet operation and the ability to set different temperatures in each zone, but some find the 250 square foot coverage claim optimistic and the app and documentation thin.

Questions and answers

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.
