Outdoor Single-Zone Units

Ductless HVAC systems are designed to provide reliable, efficient heating and cooling throughout a home or business. These systems rely on an outdoor heating or cooling unit that delivers treated air to indoor air handlers. Choosing the right outdoor unit is key to getting the most out of your HVAC system. Depending on your needs, you may be able to enjoy great energy savings by using a single-zone outdoor unit.

Your Single Zone Ductless Options

Single-zone ductless heating and cooling units provide for climate control inside relatively small homes and businesses. These units are designed to support home and business owners who want to cool only one room or area in a building. Single-zone units may be any of the following:

  • Mitsubishi Electric air conditioners
  • Heat pumps
  • Furnaces
  • Boilers

Efficiency Ratings

Before choosing a single-zone unit, you should familiarize yourself with important terms and ratings used to describe these systems. As you shop, keep these in mind:

  • SEER (seasonal energy efficiency ratio) ratings describe the cooling efficiency of heat pumps and air conditioners. Look for units with ratings of at least 13.
  • HSPF (heating seasonal performance factor) ratings describe the efficiency of heat pumps during the heating season. Look for units with ratings of at least 8.6.
  • Inverter systems feature variable speed controls to help make better use of energy.
  • Non-inverter systems run at only one speed and are ideal for buildings with high heating or cooling demands.

Single Zone vs. Multi Zone Systems

Deciding between single-zone and multi-zone ductless cooling units, heat pumps and heaters before shopping is essential. Remember that how well a given type of system will meet your demands depends on the size of your building, the area that you need to heat or cool and the amount of control you want to have over your building's temperature. Your Mitsubishi Electric contractor will be happy to explain your single-zone and multi-zone system options.

Which System is Best for You?

Buying the right system for your home or business now can save you from big headaches in the future. Carefully evaluate the answer to each of the following questions before making a purchasing decision. Remember that your comfort should be a top priority when choosing an HVAC system.

  • Do you want to heat or cool only one room? If so, a single-zone unit is the perfect choice.
  • Do you want to heat or cool more than one room? If so, consider choosing a multi-zone system.
  • Do you want to use your system for heating or cooling only? A single zone unit may meet your needs.
  • Do you want to use one unit for both heating and cooling? Consider using a multi-zone system to get the most out of your combined unit.

System Sizing

Of course, you'll also need to carefully evaluate unit size before making a final purchasing decision. Choosing a unit of the right size will ensure that you stay comfortable without wasting energy. Ask your contractor for help with load calculations. Choose the unit with the number of British Thermal Units (BTUs) needed to efficiently heat or cool your space.
