Our take on the MRCOOL DIY 5th Gen 36K BTU 2 Zone Mini Split (12K + 18K)

A two-zone ductless heat pump: one 36K BTU condenser feeding a 12K and an 18K air handler, rated 23 SEER. Its selling point is the pre-charged Quick Connect line sets with R-454B refrigerant, so no vacuum pump or gauges are needed and a homeowner can do most of the install. Each head has its own remote, and the SmartHVAC app plus Alexa and Google Home cover control. Against pro-installed multi-zone systems it trades some installer flexibility for self-installation and a Gold Fin coated condenser; owners report smooth installs and quiet, reliable running months in.

Best forHomeowners replacing window or portable AC in two roomsDIYers comfortable with basic electrical and line-set workBedroom plus living-room setups (12K and 18K heads)Year-round heating and cooling in mild to cold climates
Pros
  • Pre-charged Quick Connect line sets skip vacuuming and gauges
  • 23 SEER efficiency for a 36K multi-zone system
  • Two different head sizes match a small and a large room
  • App, Alexa and Google Home control
  • Gold Fin condenser coating resists corrosion
  • 7-year compressor and 5-year parts warranty
Cons
  • Two zones only; no third head on this condenser
  • DIY install still needs a dedicated circuit and permits in many areas
  • Line sets are fixed lengths, so routing is less flexible than field-brazed lines
  • Warranty terms can depend on registration and installation

Questions and answers

Can I really install this myself?
The refrigerant side is designed for it: pre-charged Quick Connect line sets need no vacuum pump or gauges. You still need a dedicated electrical circuit and, in many areas, a permit and inspection.
What rooms do the two air handlers suit?
The 12K head is aimed at rooms up to about 550 sq. ft. and the 18K head at up to about 800 sq. ft. That fits a bedroom plus a living room or open office.
Does it heat in winter?
Yes. It is a heat pump with heating, cooling and dehumidification modes, and owners report it kept homes warm on sub-zero nights. Output drops as outdoor temperatures fall, as with any heat pump.
How is it controlled?
Each indoor unit has a wireless remote and a digital display. The SmartHVAC app adds phone control, and it works with Amazon Alexa and Google Home.
What warranty comes with it?
A 7-year compressor warranty with limited lifetime coverage and a 5-year parts warranty. Register the unit and keep installation records, since coverage can depend on them.
Can I add a third zone later?
No. This condenser is built for two zones, and the included 12K and 18K heads fill both. A three-zone setup needs a different condenser.
