MSA12WA & MUA12WA Mr. Slim Wall Air Conditioner 13 SEER 12,000 BTU (1 Ton)

When you buy a Mitsubishi wall air conditioner, you’re buying from an industry leader in split ductless air conditioning technology. There is none better than the ductless mini split performance for quiet, easy to use and energy efficient operation. Mitsubishi MSA12WA & MUA12WA offers efficient, individual room control with allergen filtration and thanks to this new technology all of this is done without the necessity for ductwork. You can have precise control even in difficult rooms or areas like never before.

The MSA12WA & MUA12WA systems have three main components: an indoor unit (Air Handler), an outdoor unit and a remote controller. Installation is as simple as mounting the indoor and outdoor units, connecting the refrigerant lines and making a few electrical connections (HINT: An Installation Kit might come in handy). An easy installation for your authorized contractor means you will be quickly enjoying the comfort that the Mitsubishi MSA12WA & MUA12WA provides.

The Mitsubishi MSA12WA & MUA12WA ductless systems are far more efficient than conventional systems. You never again have to sacrifice air comfort due to worries about high-energy costs.

In short, the MSA12WA & MUA12WA system delivers the ultimate in comfort control for your home, improving the quality of your family’s life in ways no other product can.

Join the eco-comfort revolution

Mitsubishi is committed to being green and they are currently offering more systems than ever that meet ENERGY STAR® standards.The high efficiency of the MS A12WA & MU A12WA helps pay for itself by cutting out the need to cool the particular zone with a gas based alternative. Strong, quiet and efficient DC motors are used both indoors and outdoors. High performance fan blades, condensers and evaporators combined with variable speed inverter driven compressors are made for unmatched performance. Variable speed compressors automatically adjust to fluctuating room capacity requirements.

The temperature of any space with an indoor air handler can be controlled to provide the perfect temperature. Along with this unique benefit, this also allows you to control whether or not a particular room is being conditioned based on if it is being occupied or not.

Allergen filtration for cleaner, healthier air

The air quality inside your home is often worse than the air quality outside. The MS A12WA & MU A12WA use a sophisticated multi part filter system to remove contaminants such as allergens, viruses and bacteria from the air as it circulates within a room. The hybrid catechin filter absorbs odor causing gases. A blue enzyme, anti allergen filter reduces germs, bacteria and viruses and helps trap dust, pollens, mites and other particles in the air that plague allergy sufferers. As a result, you enjoy pristine air 24/7. A hybrid coating process makes the filter washable and if it’s properly maintained with monthly cleanings will be effective for more than 10 years.

    Efficient. Quiet. Secure.

    That's right. Reliable Mitsubishi MU A12WA Mr. Slim units deliver all of these. First its small design, smart functionality, and lack of ductwork plus INVERTER technology make it energy-efficient. Second, the unit's fan is designed to deliver air quietly and continuously with only a gentle whoosh for constant circulation and filtration. (That's why Mr. Slim systems were the first choice for thousands of churches, schools, and libraries across the U.S.) Third, because each systems installs with only a three-inch opening for connecting the indoor and outdoor units, you don't have to worry about thieves gaining access through an easy-to-remove window unit. With Mr. Slim systems you can sleep in quiet comfort with a sense of security.

    The Solution is Clear

    • Cool only the areas you want and not the areas where you are not
    • Individual zoning at the push of a button, putting you in total comfort control
    • Less then 5% cooling loss occurs in insulated refrigerant lines versus up to 40% through ducts
    • Requiring just a 3 to 4" diameter hole in the outside wall means less mess, better home aesthetics, and improved security, unlike a window unit
    • Mr. Slim models mount high on the wall so they don't disturb your view
    • Mitsubishi units add value to your home and are more efficient than old window units, saving you money

    Mitsubishi MU-A12WA's Quiet Operation

    Do you hear that? No? You barely hear our systems because Mitsubishi indoor units operate with barely a whisper.

    For example:

    • Police siren 118 decibels
    • Circular saw 107 decibels
    • Vacuum cleaner 74 decibels
    • Library reading room 33 decibels
    • Whisper-tone voice 35 decibels
    • Our Indoor Units 19 - 34 decibels (at low speed)

    Did you hear that? We hope you did.

    System Control in the Palm of Your Hand

    Mitsubishi Electric offers a comprehensive remote controller that controls temperature, fan speed and more. Choose from four modes: COOL, HEAT, AUTO and DRY. The controller also has a 12-hour ON/OFF timer for one-button control of your personal comfort.

    Warm Air, No Drafts

    Our hot-start heat pump technology provides warmth from the beginning. The fan increases in speed as the coil is warmed, reducing drafts so when you want warm air, you’ll get it.

    Auto Changeover on Heat Pump Systems (MUZ outdoor units)

    Our heat pump systems sense whether a space needs cooling or heating and automatically switch modes as needed to maintain a consistent temperature within the selected range of a single zone.

    The Mitsubishi MU-A12WA is Easy to Maintain

    With easily accessible filters, little or no ductwork to clean, and uncomplicated wiring connection points between the indoor and outdoor units, Mitsubishi systems rely on minimal maintenance, providing another level of comfort.

    The Mitsubishi MS-A12WA is Easy to Maintain

    With easily accessible filters, little or no ductwork to clean, and uncomplicated wiring connection points between the indoor and outdoor units, Mitsubishi systems rely on minimal maintenance, providing another level of comfort.

    Multiple Filters for Cleaner, Healthier Air

    Mitsubishi indoor units use a sophisticated multi-part filter system to remove contaminants such as allergens, viruses and bacteria from the air as it circulates.

    The hybrid catechin pre-filter absorbs odorcausing gases. A Blue-Enzyme anti-allergen filter reduces germs, bacteria and viruses and helps trap dust, pollens, mites and other particles; the filter uses an enzyme catalyst to help break down the sulfur atom bonds in allergen proteins, transforming them into non-allergen proteins.

    A hybrid-coating process makes the catechin filter washable and, if properly maintained with monthly cleanings, effective for more than 10 years.

    The high-efficiency MSZ-FE09/12NA indoor units incorporate the standard Catechin filter plus two more filters for triple filtration. The second filter, a Blue-Enzyme filter made of a fibrous material, also render allergens harmless using enzymes. The third filter, a Platinum Catalyst Deodorizing filter, has a ceramic surface absorption element and uses nanotechnology for high power odor absorption. This combination of filter types provides a complete air purifying system along with the ultimate comfort solution.
