20,000 BTU 16 SEER Mitsubishi Dual Zone Mini Split Heat Pump System 12+12 - Ceiling Cassette-R410A

I have been using this Mitsubishi unit for few years already. It has been a life saver in summer and frequently on cold damp days in winter. It does save me money in winter compared to oil heat. I use it to about 30 degrees after that the system seems to struggle a bit. Summer time it works great to cool my space.
I have one in the bedroom and had to turn off the rotating sensor because the sound it was making did bother me a bit.
The entire experience of buying on internet was smooth. I do installation myself and just called the guy to vacuum the lines. Much cheaper that way.

Purchase mini split and installed myself. In two years it paid for itself due to no longer being reliant on kerosene. Summer electric bills are half what they were when I had to use window ac units that were inefficient and a pain to heave in place. Only maintenance I’ve had to do is clear pollen from coils and clean dust from filters

We got this dual had mini split for our basement apartment, it has worked great. Energy efficient.

I bought this package unit back in 2021. The outdoor unit is heavy, so if you are wall mounting it like I did be sure to have a couple of helpers to lift it. It is quiet and has done well in both 105 degree summers and 10 degree winter temps. It is very energy efficient too so I can't complain there. I have two MSZ-GL units also that I use for my shop and they are great as well. If I had it to do over I would probably just stick with the GL units all around and save some money. I run them from the Comfort app so I have no need to program it from the remote, which is a feature of the MSZ-FH indoor units. But at least I have the flexibility if I need it. Overall my Mitsubishi mini-splits have been very reliable and function well. I did have one "leak" that was caused by a clogged condensate drain line in late 2025. Not sure what ultimately clogged it but a squirt of air from my air compressor, followed by some bleach water to kill any growth and it was draining like new again. So I would recommend preventing cleaning of the drain tubing once a year to prevent that from happening.

HVAC direct was great to work with. I called them directly to discuss the order before making it and they were very helpful to make sure I ordered the correct accessories (part numbers). I would definitely use them again.

We have had this system for several years. There has been just one failure in that time, the outdoor unit fan, which was covered under warranty. However, the temperature control is horrible. We have attempted all of the various modes and settings that seem to be available, but we consistently have inaccurate temperature control. Often we need to put the setpoint roughly 4 degrees above our desired temperature, but that varies widely. Sometimes the actual temperature is a steady 2 degrees below setpoint; sometimes it is 8 degrees. This is the case for both heating and cooling. It does heat and cool but not accurately enough to say that the space stays comfortable.

Got what I needed, without issue

The unit arrived just fine, and much more quickly than expected. My son installed it (it was purchased for him) and had the finishing touches done by a professional. The pro told him the Mitsubishi was a good unit, better than the ones he sold.
Perhaps one unit will be a bit small for one of the spaces, but will be adequante according to the pro.
We are very happy the way it turned out.

I recently purchased the Mitsubishi 20,000 condenser unit and the 15,000 & 6,000 BTU inside units. I can't figure out why the 6,000 BTU unit
has such a gigantic remote control compared to the 15,000 BTU unit. Can someone clue me in on this?

Also, the spec sheet on the website for the 15,000 BTU inside unit says the line connections are 1/4 / 1/2. They are in fact 1/4 / 3/8.
