Indoor Ductless Systems

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.

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.
