Split-system air conditioners for homes without air ducts

 

 

 

 

Many newer systems also function as heat pumps, providing primary heating as well as cooling.

Advantages

  • Easier installation than central systems
  • Air ducts not required
  • Zone control provides balanced comfort and energy savings
  • Quieter than window or thru-wall units
  • More secure than window air conditioners
  • Eliminates losses common in air duct

Disadvantages

  • Split-systems cost about $1,500-$2,000 per ton (12,000 Btu/h) of cooling capacity. This is about 30% more than central systems, and may cost twice as much as window units of similar capacity.
  • Qualified contractors may be difficult to locate in many smaller centres, until these systems are in wider usage

 

 

 

 

Note: The term, "split-system," can also be used to describe conventional central air-conditioners and heat pumps. If you’re shopping for “ductless” systems, make sure the dealer understands which system you are looking for. Ductless split-systems are sometimes referred to as “mini-splits."
