With sound levels as low as 20dB, the M-Series provides quiet, energy-efficient operation, along with effective zone heating.

"mszfh12na Hyper Heat NOISY!"
I have 2 Hyper Heat 12k systems installed. I wish Mitsubishi was honest about these Hyper Heats being "silent". They are whisper quiet in cooling mode, but in heat mode.......below 32 degrees. Holy crap. If you don't hear the variable speed motor ramping up and down all night while trying to sleep, you are deaf. They do put out the heat, but they also vibrate and make this buzzing noise that is very annoying.

"Best mini-split heat pump brand!"
When I had my upstairs office built (over the garage) 8 years ago, I went with a Mr. Slim (also Mitsubishi) and loved it. It didn't have a 10-year warranty back then, but it worked great even though it was beginning to become louder and needed de-clogging recently. So, the HVAC people said it sounded like I would need a new mini-split heat pump and offered me a deal on another brand. Bad mistake, the other brand (Samsung) was was like driving a Ford Pinto instead of a Mercedes Benz. After some haggling with the HVAC people, I told them I wanted only a Mitsubishi for several reasons: Dependability, total control over temperature and fan and airflow and their auto settings truly work. It's also 2-3 times quieter than the other brand. Plus Mitsubishi is the only brand I know of, a mini-split heat pump company, that has a Customer Care center that you can call or chat with most any time. I learned the hard way, Mitsubishi is absolutely the best in product quality, user assistance, manuals are excellently written, and the M-Series runs perfectly, even quieter than Mr Slim. The other brands require that you go through an HVAC person to get any information on remote usage, reading manuals, etc, and you have no way to contact the vendor for any assistance at all. The other brand I tried was terrible (wouldn't let you control the temperature, auto mode didn't work, odd noises, loud blower). Mitsubishi is truly the cream of the crop in every imaginable way. I'll never use any other brand for a ductless mini-split except Mitsubishi!

"Our Mitsubishi Heat Pump Customizes the Temperatures in Our Home!! Love it!!"
We live in Orlando, Florida and living here sometimes makes heating and cooling your home complicated because of the extreme heat and sometimes cold winter month chill. We use a different type of heating solution that helps us fight winter chill in the areas of our home where we spend most of our time. We use the Mitsubishi M-Series - 9,000 BTU - Mini Split Indoor Unit - Wall Mounted - Heat Pump. We love it! We can use it to supplement our entire home heating system. It was inexpensive, easy to mount, and significantly lowers our overall heating bills. We have used this for almost one year. We can easily customize the temperature of a room. It also keeps the air clean and is reliable. It also has a built in dehumidifier. We love our unit and are so happy we made the decision to purchase it! Would recommend to anyone who is interested in customizing specific room temperatures!

"Great, efficient heat pump"
I love our heat pump, it's very efficient and much quieter than I expected. We've had it for about a year and so far have no complaints and have not needed any repairs or had any problems with it. I think Mitsubishi is great, specifically their hyper-heating models. I know several people that have similar heat pumps to ours but different brands and I have to say, compared to others, ours is by far more efficient where we have never needed any kind of back-up heat supply, even in the coldest winter days. Our electricity bill is also very reasonable; even though I expected it to be very high I was pleasantly surprised that it was much lower than what I thought it would be. And compared to our previous heating source (oil furnace) the total cost per month is way lower too, compared to buying oil all the time. The heat pump itself isn't cheap, but it was definitely a great investment!

"Mitsubishi - MZ-FH09NA"
This review is for the Mitsubishi - MZ-FH09NA heat pump. I had this installed ( I am no Bob Villa, that's for sure). Anyway, I had it installed by a professional, and so far I am very satisfied. I had it installed when my home was being built, so I am the primary owner. It has given me zero problems. The thing that I like the most is that it has a built in dehumidifier! No more ugly dehumidifier sitting around because this baby has one already built in. I live in the Midwest and it can get very humid in the summer, and without this my home would be swampy and quite unbearable. I can't say that there is a negative, because I've only had it for 6 moths. I'll send an updated review next year. So, all and all, I love this heat pump and would highly recommend.

"Pretty Happy with my Single Zone Mitsubishi"
I just purchased my MUZ-D Mitsubishi "Single Zone" heat pump system at the behest of a friend who I complained to about my house getting way too cold in the winter. He suggested this model, the same kind I have. I purchased it just before the winter hit last year for my bedroom. I ran the pump at night, when it got really cold, and it had no problem keeping my room warm. The machine was not loud at all and you hardly notice it is in the room. For the short time I've owned it, I haven't really had any problems with it. My only real gripe about the machine is how much it costs to run. I did some research online that said my electric bill would not go up substantially. However, in the months that I used the machine, it went up by 30%. I am not too upset by this, since ht machine has done a wonderful job. It was just more than I was expecting. Even though it has one negative against it, I would suggest this brand over other system. Mitsubishi makes a wide variety of high quality products, and this is one of them. I really liked it and I foresee myself getting another when this one eventually breaks down.
