Indoor Ductless Systems

Indoor air conditioning units are responsible for delivering pleasantly treated air from your heating or cooling unit to your home or business. Whether you are considering having a new system installed or want to update your current system, it's important that you choose indoor units that are compatible with your needs and fall within your budget. You'll find that Mitsubishi Electric offers a wide variety of indoor units designed to work seamlessly with ductless air conditioners and ductless heat pumps.
Introducing the STAR Lineup of Ductless Air Conditioning and Heating Units, a breakthrough in pure comfort.

We offer more ENERGY STAR® systems than ever, incorporating eco-comfort technology, dual and triple-allergen filtration, and whisper-quiet operation. The new technology revolutionizes the heat pump and with a space-saving design means easy and unobtrusive installation.

Wall Mounted Indoor Units

Eco-comfort technology makes these systems smarter in how they use energy and minimizes their impact on the environment. Plus there are many advanced features like the i-see™ Sensor, that automatically detects room temperature differences and adjusts for greater comfort. Mitsubishi Electric's advanced multi-stage filtration systems dramatically reduce allergens and help eliminate odors. And our indoor units operate with sound levels starting as low as 19dB(A). That sound is even quieter than a human whisper.

Understanding Indoor HVAC Units

Sometimes known as air handling units, indoor HVAC units are an integral part of your heating or cooling system. They distribute air to your rooms. Most of these units can be controlled individually via a thermostat or wireless remote. Indoor units can be used with both single-zone and multi-zone systems, making them one of the most flexible HVAC options available to today's consumers.

Product Types

Mitsubishi Electric offers three primary types of indoor air unit. Each type of unit is designed to meet specific system needs while providing a high level of efficiency. Mitsubishi Electric is proud to offer wall-mounted, floor-mounted and horizontal ductless indoor air conditioning units.

Product Ratings and Descriptions

When shopping for an indoor air conditioning unit, you're likely to run into a number of specialized terms and definitions. Some of these terms describe the efficiency of units while others provide basic information about how the unit operates. Familiarize yourself with these four key terms before you start shopping:

  • SEER (seasonal energy efficiency ratio) ratings are used to describe the cooling efficiency of heat pumps and air conditioners. Look for SEER ratings of 13 or higher to ensure great energy savings.
  • HSPF (heating seasonal performance factor) ratings describe the heating efficiency of heat pumps during the cold season. All new heat pumps must have a rating of at least 6.8. Look for units rated with an eight, nine or 10 to enjoy the best savings.
  • Units that use an inverter compression system are designed to allow the compressor to run at variable speeds. This can help to save energy while providing for stable cooling.
  • Units that use a non-inverter compression system run the compressor at the same speed at all times. This can lead to some losses in energy efficiency and a decreased unit lifespan.

Your Mitsubishi Electric Air Conditioner and Heat Pump Options

Whether you are looking for indoor units to accompany a Mitsubishi Electric heater or air conditioner, you'll have three primary choices. Remember that choosing the right system for your needs will require careful evaluation of your building and budget. You'll be able to choose from the following system types:

  • Wall-Mounted Systems: These systems feature air handling units that are mounted high up on walls. They provide excellent cooling power and are ideal for homeowners who want to put their air handling units out of reach.
  • Floor-Mounted Systems: These systems feature large units that are situated on the floor and provide ground-level heating and cooling power.
  • Horizontal Ductless Systems: These systems can fit into slots cut for ductwork to provide an attractive, ductless comfort solution.

Which Ductless System is Best for My Needs?

Before you can choose the right ductless system for your needs, you'll need to have professional load calculations completed. These calculations will allow you to determine the size unit you need to use in your home. Remember that having a professional complete Mitsubishi Electric ductless heat pump installation and Mitsubishi Electric ductless air conditioning installation is an absolute must.
