Single-zone heating and cooling units are connected to a single air handler inside your home or business. The outdoor air unit and indoor air handler are connected by a refrigerant line that facilitates the carriage of treated air from the outdoor unit to your indoor spaces. Remember that a single-zone unit can only be connected to one air handler. These units are ideal for:

  • Homeowners who only want to cool one or two rooms.
  • Small business spaces.
  • Small rental properties or guesthouses.
  • Garages, basements and building additions.

Product Ratings and Descriptions

When shopping for a single-zone outdoor unit, you’re likely to run into some technical terminology. Familiarize yourself with the following four terms so that you’re best prepared to pick the unit that meets your needs:

  • SEER (seasonal energy efficiency ratio) ratings will help you determine the efficiency of a heat pump or air conditioner. Look for ratings between 13 and 26 to enjoy the greatest energy savings.
  • HSPF (heating seasonal performance factor) ratings are used to gauge the heating efficiency of heat pumps. Look for ratings between 6.8 and 10 to enjoy the greatest energy savings.
  • In inverter compression systems, the compressor is run at variable temperatures depending on heating or cooling demands. This type of system provides the highest efficiency possible.
  • In non-inverter compression systems, the compressor runs at the same speed any time heating or cooling power is needed. These systems offer good energy efficiency.
