About this Item

Mitsubishi M-Series Multi Zone Concealed Duct Heat Pump System, Bundle Includes - Outdoor Unit: MXZ-4B36NA-1, and Indoor Units: SEZ-KD18NA4.TH (x2)
  • Energy Star Estimated Cooling Cost: $634

Product Highlights

IMPORTANT: This model requires two remote controllers, which must be purchased separately to complete the installation. Select from either MHK1 or PAR-32MAA-J.

System Includes:

  • Outdoor Condenser Model: MXZ-4B36NA-1
  • Indoor Concealed Duct Model: SEZ-KD18NA4.TH (x2)
  • Required, but not included: 1/4" x 1/2" line sets (x2)

This MR SLIM INVERTER-driven two-zone heat pump system, with concealed horizontal ducted indoor units, is ideal for conditioning rooms with limited wall space, because the evaporator stays hidden in the ceiling, floor, or closet.

Control Options
This system is compatible with the optional MHK1 wireless, RFI-RedLINK™ enabled, full-function wall mount controller, allowing homeowners to control their unit from a remote PC, smartphone or tablet (sold separately). If you prefer a standard, fully wired and functioning wall mount control, this system also works with the PAR-32MAA-J (sold separately).

INVERTER Technology
The M-Series INVERTER-driven compressor and linear expansion valve (LEV) works with the system’s sophisticated electronic controls to detect temperature changes in a room or zone, automatically changing speeds to adjust for precise capacity and temperature control.

Quiet Operation
Mr. Slim Indoor Units operate at very low sounds levels (19-35 decibels). According to a study performed by the National Institute for Occupational Safety and Health, most Mr. Slim Indoor Units are quieter than a human whisper (30 decibels) at low speed.

Environmentally Friendly
Mitsubishi was clearly taking the environment into consideration when designing the M-Series line by using R410A refrigerant with zero Ozone Depletion Potential (ODP), 83% recyclable components, and washable filters made from natural materials on all models.

Additional Features & Benefits

  • Auto fan speed feature plus three speed settings available (Low, Medium, High)
  • Ultra thin indoor unit body: 7-7/8" high
  • Built-in condensate removal mechanism with up to 21-11/16” lift
  • Long-life air filter is included with indoor units
  • Quiet outdoor operation ranging from 49-58 dB(A)
  • Self-check function with integrated diagnostics
  • Auto restart feature works after a power outage
  • Outdoor condenser powers the indoor units

Please Note: Mini Split Systems must be installed by a licensed Contractor with an EPA Refrigerant Certification to qualify for warranty.

Which line set kit do I need?
This system uses (2) 1/4" x 1/2" line set. These are sold separately, and you can choose from our 15 ft, 25 ft, 35 ft, 50 ft, and 75 ft lengths. The length needed depends on the needs of your project and how you will set up the system (distance from outdoor condenser to indoor air handler).

Can I install this myself?
While installation of a ductless split is much easier than a central air system, it's still much more advanced than installing a window unit or portable. Furthermore, the manufacturer warranty is only valid if a licensed professional does the installation. So while it is possible to do the installation yourself, we strongly recommend you hire an HVAC professional in your area.

Is this backed by a warranty?
Yes, it comes fully backed by a manufacturer's warranty (click here for more details), and ComfortUp is an authorized online seller of these systems. Our Customer Care Team will provide assistance should you ever need to file a warranty claim with the manufacturer. Please be aware that only systems that are installed by a licensed HVAC contractor are backed by the warranty. Proof of licensed installation is required. The receipt/invoice from your contractor should be sufficient.

Note: Concealed ducts need to be installed in a conditioned space in order to operate effectively. It’s highly recommended to discuss this application with a licensed contractor that is experienced with the installation of these units.
