Features
- H2i Technology
- Low and negative ambient temperatures don't bother the MXZ-3C24NAHZ2. It is rated for 100% heating capacity at 5 degrees F and continues to provide heating in outdoor conditions as low as -13 degrees F.
- Precision Temperature Control Technology
- This outdoor condenser is equipped with inverter technology and an electronic linear expansion valve. By adjusting compressor speed and refrigerant flow, these components provide precise temperature control and incredible efficiency.
- Integrated Base Pan Heater
- MXZ-C outdoor condensers have a factory-installed base pan heater in the drain pan. This prevents condensate from freezing and damaging the unit in frigid climates.
- Mix and Match
- The MXZ-3C24NAHZ2 is compatible with more than a dozen different indoor units. It even works with the advanced MSZ-FH indoor units. This makes it easy to design a system that suits your home, no matter how it is arranged.

Quiet & Works Quite Well

Review Posted 06/27/2018
I received the unit in April and finally finished the install a few weeks ago. I poured a 4ft x 4ft concrete pad for the compressor but honestly the compressor is so quiet (I think that my cat makes more noise when she is sleeping) and vibration free that the pad was totally "overkill". The 2 indoor units are also equally as quiet.
With regard to the install. I did the complete install myself including the required 30 amp outdoor disconnect, copper liquid and gas lines, as well as evacuating and then charging the system with additional R410A.
The electrical was easy, the plumbing a bit harder, and the system setup (charging with R410A) tougher still.
The system comes pre-charged with enough R410A for the first 25ft of liquid and gas copper pipe. My 2 indoor units required 65 ft (which was the max allowable length) so I needed to add about 1 lb of refrigerant.
For the additional piping I used pre-insulated line set 1/4 and 3/8 (available on Amazon and other places) which saved me from having to insulate the exposed copper by hand. A good flaring tool is essential to making connections that will hold pressure.
The hard part was pulling a vacuum, breaking the vacuum with nitrogen, then pulling a vacuum again, adding extra R410A, releasing the factory loaded refrigerant, then testing the system. You will need a vacuum pump, gauges, a scale to weigh the added R410A, and a ton of patience. There are quite a few videos on YouTube showing how to perform these tasks and you will need to spend some time being educated. Or you could just call an HVAC guy to charge the system for you but this might cost you a few benjamins.
To hide the copper lines on the outside of the house I used a 2in x 3in white plastic raceway product from Electriduct. These were less expensive and look nicer than what was available on Amazon.
How well does the system work? I have 2 9000 BTU units on opposite corners of a 1500 ft2 home. The house is cool dry and comfortable. There is absolutely zero noise from any of the components. The system includes a dehumidifier mode which is handy when the humidity is high but the outside temp doesn't demand full air conditioning.
Yes the system is that good.

Review Posted 07/20/2017
Went for the Mitsubishi system above the others as recommended and am so glad i did. Got the system installed by a local company that didn't mind that i had purchased the equipment myself. Its super quiet and easily cools the first floor of my house.

Love the mitsubishi heat pump

Review Posted 06/27/2016
The HVAC installer I used before passed on this one when he heard I needed ceiling cassette this time, not wall mount. I decided to order from eComfort and do it myself...
Chris was very helpful putting system together and all needed accessories. System fired right up after installation, haven't used it much yet, as place is still under construction.

Did it (almost) all by myself

Review Posted 05/31/2016
I recently purchased the MXZ-2C20NAHZ along with the 12K and 9K floor mounted indoor units. I also purchased two Mitsubishi line sets, wall brackets, disconnect switch and drain tubing. All items were received with very quick shipping and no issues or delays.
I installed all items with the exception of the line sets myself. I mounted the outdoor unit, indoor units, installed a new floor drain in my attic to collect condensation, made a new 220 line with disconnect and ran the 14/4 cables to the indoor units each with a disconnect.
I then hired an HVAC professional to assist with the installation of the refrigeration lines and to pressure test the system. The project went smoothly and I saved about 5K over a professional installation. I would recommend this to any hard core DIY’er. Make sure to follow all local code requirements and obtain permits if required by your municipality.
