Mitsubishi Hyper Heat Mini Split Reviews

Why Choose Mitsubishi?

Mitsubishi Electric started their climate control division over 30 years ago. With products ranging from Energy Star optimized systems to the first VRF (Variable Refrigerant Flow) zoning system, Mitsubishi has been leading the charge in the US.

In 1990 the HVAC division relaunched the mini-split systems for US distribution. The company was so successful that by 2013 they had to re-double their factory size and relocate the division to larger headquarters. In 2011, the mini-split ductless ACs won the prestigious BuildingGreen award Top 10 and hasn’t looked back.

If you want a company that knows quality, reliability, and dedication to their craft, Mitsubishi is that company. No matter which model or system you go with, the Mitsubishi name on the machine will give you high-quality, long-lasting comfort in your home.

Considerations for Buying a Mitsubishi Mini Split System

Before you click the buy button on any of the models, there are several factors you need to consider. Below is a brief Mitsubishi mini-split AC buyer’s guide. Read through it and make sure you have planned for everything.

Energy Efficiency/SEER Rating

Most electrical systems will have a rating that tells you how efficient it is. The Energy Efficiency Rating will determine the power consumption of the unit over a particular period of time and give you an estimate of how much (annually) it should cost to operate that equipment.

Energy Star

Energy Star systems, like those built by Mitsubishi, have higher SEER numbers than a lot of the competition. The higher the SEER number, the less you need to pay on your monthly energy bills to run the mini-split AC.

However, all systems have slightly different ratings based on size, power needs, and amount of use. The key is not to look for the highest SEER rating, but to find the model with the power to cool your home the most efficiently. Remember, a system running longer will cost you more, regardless of the SEER rating.

Mini Split Compressor Options

There are a few different types of compressors to choose from as well. The standard compressor is reliable, does its job, and doesn’t require a lot of maintenance. However, they aren’t the most efficient types available.

Mitsubishi also uses inverter-driven compressors that help reduce power consumption by drawing only the required amount needed to cool or heat the space.

The initial cost for these compressors, though, is a bit higher. While the energy savings over time may offset this cost, your budget will help determine which type is best for you to start with.

Condenser Fan Options

The condenser fans aren’t often thought about. However, they can be more efficient. Mitsubishi uses features that allow the fan to run only when needed and to help prepare the system to blow hot air immediately or cold air upon startup without drafts.

Other features, like zone control, allow the fans to run less frequently and more efficiently. These additional fan features will enable you to run the system for more extended periods or more often and not have such a drastic draw on the power consumption.

Heating Options

A lot of mini-split systems will offer heating as well as air conditioning. However, it is important to understand the types of heating offered. Some mini-split AC systems use heat pumps instead of heating elements. This allows you better control of the heat and where it is pushed to but can be less efficient.

Heating elements in the evaporator portion will be more efficient and heat quicker, but cost more in the beginning. The choice is yours, though, and both options will heat your room to temperature, regardless.

Noise Levels

Quiet running systems are almost a must, but it is a feature we often overlook. Perhaps we expect the air conditioner or heater to be quiet, but this isn’t always the case.

Noise levels when running are affected by the operation mode, fan speed, and where the vents are located. In most cases, the Mitsubishi systems are quiet enough not to disturb daily life. You won’t need to adjust the volume on your TV or your conversation when the system is running.

How Noise is Measured

Noise levels, measured in decibels (DB), tell you how loud something is at a certain distance. A hairdryer, for example, will produce about 65dB at 15 feet. Your Mitsubishi mini-split system will be quieter than this. Often in the low- to mid-30 dB range, these systems are quiet enough to run consistently without being noticed.

Price & Warranty

The final thing to consider will be your budget. While most mini-split systems are affordable for most budgets, the additional features and options can raise the price significantly.

Staying within your budget will help your peace of mind and allow you to enjoy your investment even more.

You should also pay attention to the warranty. While the period of the warranty and its coverage are important to understand, you need to read through the warranty items to make sure you qualify.

Some systems will require professional installation for the warranty to take effect. If you install the mini-split system as a DIY in these cases, you may not be covered.

Unique Features of Mitsubishi Ductless AC Units

Mitsubishi Filtration

Mitsubishi mini-split systems use up to three different types of filters. The company has shortened them to “D,” “E,” and “N.” The D filter is the deodorizing filter that is a washable filter designed to trap and eliminate odors and odor-causing bacteria from the air.

The E filter is an electrostatic filter made specifically to trap and collect in-home allergens. Allergy-causing enzymes and particles like mold, mildew, spores, pet dander, and pollen are all captured in this washable filter.

The N filter is a non-replaceable semi-permanent Nano platinum filter. You can wash it, of course, and it is designed as the first layer of defense against bacteria and viruses. Instead of the common catechin (green tea bioflavonoid), nano platinum is a superior antibacterial material.

Hyper Heat

Hyper heating is a new technology introduced by Mitsubishi (known as H2i technology) that provides warm air and heat to the home in extreme outdoor temperatures. While heat pumps are efficient, once the temperature drops below 23 degrees (F), most heat pumps require a supplemental heat source to continue to operate.

At 23 degrees, the Mitsubishi units are still operating at 100% efficiency. The systems continue to run without the need for supplemental heating to temperatures as low as -13 degree (F) while maintaining over 75% efficiency. Couple that with instant heat, a technology that provides no draft and warm air the moment you turn it on, and you have a highly capable winter solution.

I-See Sensors

Another newer technology built-in to most Mitsubishi mini-split AC systems is the 3-D I-See sensor. This is an active sensor that has three settings (Active, away, and off). In essence, the sensor is a motion detector that scans the room looking for movement through heat signatures.

The sensor will tell if a room is occupied or not and will adjust the desired temperature accordingly. This means if you are in a room more often, the temperature in that room will maintain the set temperature on the thermostat.

You can also set this to away mode, where it will reduce the number of times the AC or heater comes on when no one is home, reducing usage and power consumption to improve energy savings. The I-See option can also be disabled entirely if you wish.

SEER Ratings

When it comes to energy savings, there are few better than the Mitsubishi models. With an average SEER rating of 22, these units cost less to operate than some portable AC units and even more affordable to operate year-round than even the most efficient window units.

Comfort Control Options

Along with the I-See sensors, there are other comfort control options available, too. Zoned monitoring is one of the most advanced methods of temperature control there is without there being a smart-app feature.

Zoned monitoring takes the temperatures from the sensors at the units in various rooms to determine the overall temperature of the home. You can alter the zones with the I-See to only read temperatures in occupied rooms if you wish.

Instead of a central location to read a single temp, the zone control maintains the set temperature in the rooms that are occupied, saving you time, effort, and money.

You will also find compressor inverter technology. Not only does an inverter save wear and tear on the compressor, but it also allows for even heat and cold distribution. Inverters prevent the compressor from doing massive power draws on startup and provides you with hot or cold air the moment the system turns on.

Noise Levels

The Mitsubishi ductless mini split systems are some of the quietest operating systems on the market. With few exceptions, the average decibel rating of the system running on high mode is around 22dB.

At 22dB, the system is quieter than a whispering conversation in a quiet room. There won’t be any interference of noise when you are watching television, have friends and family over, and are talking. You can even listen to your music without the need for headphones, too.
