Outdoor Multi-Zone Units

Outdoor ductless heating and cooling units provide the power needed to keep your home or business comfortable year round. One of the first decisions you'll need to make when choosing a new outdoor unit is whether you will use a single- or multi-zone unit. Multi-zone units allow for individual, zoned control of set rooms and areas inside your building. These units offer powerful, efficient heating and cooling solutions for both residential and commercial spaces.

Your Multi Zone Ductless Options

Multi-zone outdoor units are paired with indoor air handlers in order to provide cooling or heating power in your home or business. These outdoor units may be Mitsubishi Electric air conditioners, heat pumps or heaters. They are paired with multiple indoor air handlers in order to provide for completely customizable temperature control in your home or business. Multi-zone units are perfect for consumers who need to cool or heat large spaces and for those who want to set different temperatures for each room in their building.

Efficiency Ratings

Choosing a multi-zone outdoor unit with high efficiency ratings will ensure that you enjoy great energy savings and total comfort. Familiarize yourself with the following ratings and system type descriptions:

  • SEER (seasonal energy efficiency ratio) ratings help consumers find air conditioners and heat pumps that cool efficiently. Buy a unit with a rating of at least 13.
  • HSPF (heating seasonal performance factor) ratings help consumers find heat pumps that heat efficiently. Buy a unit with a rating of at least 8.5.
  • Non-inverter units run on one speed all the time. This means that the unit will kick on to full power even if your building only needs to be cooled for a short amount of time.
  • Inverter units run at variable speeds. This means that the unit will choose the most efficient speed at which to produce heated or cooled air for your building.

Should You Choose A Multi Zone or Single Zone Unit?

Choosing between a single- or multi-zone unit is a simple matter of determining how you want to heat or cool your space. If you are currently using an HVAC system, think about how well it has met your needs. If you were pleased with the heating and cooling power of that system, stick with a similar type of unit for replacement. Remember that investing in the right system now can help you cut down on energy costs.

Evaluating Your Options

Ask yourself the following questions before deciding between a single- or multi-zone unit:

  • Do I need to heat or cool more than one room?
  • Do I want to control the temperature of each room or area individually?
  • Do I want to use a combined heating and cooling unit?

If you answered yes to these questions, a multi-zone system is likely the best choice to meet your heating and cooling demands.

System Sizing

Of course, choosing the right size unit is essential to meeting your heating and cooling needs. Ask a contractor to assist you with load calculations. Use the total square footage of the area that you need to cool in order to determine the number of British Thermal Units (BTUs) that your heater, air conditioner or heat pump must have to cool or heat your space efficiently.

Working with Trusted Mitsubishi Electric Contractors

Working with your local Mitsubishi Electric contractor is the best way to ensure that you choose the right multi-zone unit for your needs. Remember that your contractor can assist you whether you need to choose a unit for residential or commercial use.
