Reviews by Central Air Conditioner Series


Mitsubishi Room Air Conditioners

Inverter models of room air conditioners in the M-series are available as wall-mounted, floor or 1-way cassette units, with cooling capacities from 1.5 to 7.1 kw. Some inverter models only have indoor units and some have outdoor units equipped with anti-freeze heaters. High-end units employ a large blower fan, allowing the motor to efficiently operate at a decreased speed without sacrificing cooling capabilities.

Fixed-speed room air conditioners are available for wall-mounted installation and have 2.0 to 8.0 kw capacities. Included in the variety of M-Series air conditioners are models offering an i-see Sensor temperature control and a Plasma Duo air filtering and purification system. Additionally, the “Mold Fighter” function is an option for decreasing mold spore growth.

Mitsubishi Packaged Air Conditioners

 [ Mitsubishi Series : Mr. Slim ]

The company’s packaged units, branded as Mr. Slim, also come in several options. The S Series includes indoor inverter units with capacities ranging from 2.5 to 7.1 kw. The P Series includes several indoor power inverter units, available as 4-way cassettes, wall mounts, ceiling suspensions, concealed units, standing units and more. In addition, the standard inverter packaged units consist of an indoor unit with two outdoor units, while fixed-speed models have heat pump and cooling only units. Many of these units have a side-flow configuration and long piping lengths for easy and versatile installation, and feature automatic fan speed adjustment.

Small Multi-System Air Conditioners

Mitsubishi’s MXZ Series of small multi-system air conditioners range from 3.0 to 14.0 kw. With eight models from which to choose, these units are compatible with the company’s indoor units and are designed to fulfill multi-system air conditioning needs.

Large Multi-System Air Conditioners

Mitsubishi’s CITYMULTI system outdoor units offer extremely quiet operation and coefficient of performances ratings that the company says are among the best in the industry. With 16 models from which to choose, the installation of this line is designed for flexibility making it adaptable to various conditions.

Care and Maintenance

Maintenance of Mitsubishi air conditioners greatly varies among the models, although air filter cleaning and replacement for all indoor units is advised by the manufacturer. In some cases, the manufacturer suggests cleaning the interior of room units approximately every five years. It is important that the homeowner discuss maintenance with the seller as such care will be unique to the product and product combination installed.


Mitsubishi’s packaged air conditioners come with a 5-year parts warranty that can be used only by the unit’s original owner. If installation of the product is completed by a Diamond Contractor, coverage may be extended to 7 years. The compressor is covered for 7 years, and it is important to note the consumer must pay all labor costs. Warranty information for M-series models can be obtained from the dealer.

"650 repair bill for leak, after 2.5 years"

2.0 rating
Somewhat Unsatisfied

Six hundred dollar repair 2.5 years after installation. Not heavily used. That is unsatisfactory. Not covered by warranty.

"It's not a warranty. It's a lottery."

The unit that I now have to refurbish myself, that I just bought new from the supply house. Now this unit, if I do repair the leaking coil myself as Mitsubishi Customer Support wants me to do. Why should a defective unit you have to refurbish right off the shelf be sold at the full price of a unit?? How do you explain this to the customer? Why should they be ok with a unit that never worked from the installation and had two problems in the first few weeks of its life – a fried circuit board and a refrigerant leak. I understand the warranty covering a unit that breaks after a year of operation. But a unit that was never normal off the shelf – that you have to reassemble piece by piece – I just don't get it. In the lottery of defective units, I got the defective one, and I don't get a new one even though I just paid for it. I just wish this was advertised so that I could price an extra several $100 into the quote for the customer.

"Failing Mitsubishi compressors"

Very Unsatisfied

We installed 47 Mitsubishi hvac units one year ago, in 2011. We have had to replace 5 pumps and now a compressor..after less than one year of service! The cost is $1,800 for parts and labor, which is not covered.

I have a Mitsubishi ductless ac which was installed over 5 years ago and have had it repaired twice, one under warranty and once not. The parts were avaialble and only had to wait 1 day for one and the SAME day installed for the other repair. I can believe today with UPS, any part can't be installed the next day. My suggestion is find a certified Mitsubishi dealer. They have to meet and maintain certain standards, whcih prevented me any problems.
