- Great rooms
- Big garages and workshops
- Studio apartments
Best for: homeowners building a new MRCOOL DIY 36K single-zone system or replacing their current 5th Gen outdoor unit
Features
- 18 SEER2 inverter efficiency. The compressor ramps up and down instead of cycling on and off, which is what keeps power bills down.
- Built to last outside. Gold Fin coating on the condenser resists corrosion from rain, salt air, and the elements.
- Pre-charged and ready. The refrigerant for the standard line set length is already in the unit, so there is nothing to add.
- Connects by hand. Pre-charged Quick Connect line sets thread on with basic hand tools. Open the valves and the system is charged.

If you are replacing an existing 5th Gen 36K condenser, this is the right part. The system runs on a dedicated 208/230V circuit.
