Mitsubishi Hyper Heat Mini Split Install and Review O
There are many mini split systems available from several different manufactures.

Mitsubishi is one such manufacture that is known for its well built units and good warranty.

They have many packages that can be installed including the Hyper Heat model which is designed for colder temperatures.

Mini split heat pump systems work very well cooling during the summer but can struggle to heat during the winter when the temperature drops too much.

Most units can heat down to 10 degrees Fahrenheit but will start to have problems when the temperature drops much more.

The Mitsubishi Hyper Heat system is rated to provide 100% heating capacity at between 0° Fahrenheit and 5° Fahrenheit outdoor ambient, and up to 85% heating down to -13° Fahrenheit outdoor ambient temperature.

This makes it the best mini split system for very cold climates.

Installation
The install for a Mitsubishi Hyper Heat is the same as most other mini split packages.

The outside condenser is placed on a pad, blocks, or stand.

An inside bracket is bolted onto a wall for the inside unit to hang on.

The inside unit is mounted on the wall bracket.

The copper line-set is connected. The copper tubes is what transfers refrigerant between the inside and outdoor unit transferring heat.

The line-set is not included with the kit and needs to be bought separately.

The electrical is hooked up. This includes control wires between the inside and outdoor unit along with the AC power.

After it is all hooked up a vacuum is placed on the system and tested for any leaks before releasing the refrigerant.

Operation
The unit comes with a nice remote control with a small display for controlling the temperature.

The inside unit is able to detect temperature zones in a room and directs air flow to the spot.

It has a sensor built-in that detects cold or hot spots and along with fins is able to send air to that location.

Like most all mini split units it is very quiet almost silent with only noise from the inside fan motor.

Summary
Mitsubishi mini splits system are some of the best units available.

They are highly efficient, very well built, and have very good warranty.

The SEER rating is 26 which is one of the highest available.

The main downside is the cost since they cost more compared to other systems.

Also they are not as do-it–yourself friendly as other units and mainly meant for a professional HVAC tech to do the install.

They can be installed buy a home owner but would require more skill compared to other kits.

For example no line-set or control wires are included and need to be bought separately.

This is not a huge problem for a more advanced home DIY type person but may be a problem for anyone new to a mini split install.

If you do install the unit yourself be sure to first watch some YouTube videos first like those below.

As always be sure to read the reviews on Amazon, forums, here, or elsewhere to be sure any unit is a good fit for you.

    Had a Mitsu hyper heat installed outdoor unit is MXZ3C24NAHZ, Indoor zone 1 MSZFH06NA, Indoor zone 2 MSZFH06NA, Indoor zone 3 MSZFH15NA. Seemed to cool well without attic or floor insulated, now that it is 30F outside, thermostat remotes set at 72F, indoor temp 65F, fans on automatic mode stay on low speed, air temperature coming from indoor heads is 74-76F. Any ideas? Thank you

    Is there any energy use difference between ac mode and the dehumidify mode?

    Bought a new Mitubushi 18000btu heat pump. Works great in cooling, horrible in heat. Plastic makes popping and dripping noises, coil makes pinging noises as unit heats and cools down. Mitubishi has never heard of such a thing and my only recourse is to pay for someone to diagnose problem and if unit is deemed defective I must also pay for repair or replacement. Hundreds of dollars with no guarantee, and no labor warranty. Beware
